hi there! heres my answer for you...

Answer:

you started at (-5, 4)

Step-by-step explanation:

do what the instructions given said but in reverse. so move up 7 units and move back down 1 unit and you will find where you started.

hope this helps. have a good one!

The coordinate of the point from where we started will be (1, -2).

A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.

You move up 1 unit and down 7 units. You end at (-5, -2).

Let the initial coordinate be (x, y). Then the transformation is written as,

(-5, -2) → (x + 1 - 7, y)

Compare the abscissa, then we have

- 5 = x + 1 - 7

x = - 5 - 1 + 7

x = 1

Compare the ordinate, then we have

y = -2

Then the coordinate of the point from where we started will be (1, -2).

The solution to the systems are (1, 1), (-3, -1), (1, -2), (2, -1), (7, -1) and (-2, 2)

System 1

In this case, the system of equations is given as

y = -3x + 4

y = 3x - 2

Next, we plot the graph of the system of equations

In this case, the point of intersection of the equations represent the solution to the system

From the graph, the lines intersect at (1, 1)

So, the solution is (1, 1)

System 2

In this case, the system of equations is given as

y = x + 2

x = -3

Next, we plot the graph of the system of equations

In this case, the point of intersection of the equations represent the solution to the system

From the graph, the lines intersect at (-3, -1)

So, the solution is (-3, -1)

System 3

In this case, the system of equations is given as

4x + y = 2

x - y = 3

Next, we plot the graph of the system of equations

In this case, the point of intersection of the equations represent the solution to the system

From the graph, the lines intersect at (1, -2)

So, the solution is (1, -2)

System 4

We have

y = 4x - 9

y = x - 3

Substitute y = 4x - 9 in y = x - 3

4x - 9 = x - 3

Evaluate the like terms

3x = 6

So, we have

x = 2

Recall that:

y = x - 3

So, we have

y = 2 - 3

y = -1

So, the solution is (2, -1)

System 5

We have

x + 7y = 0

2x - 8y = 22

Make x the subject in x + 7y = 0

x = -7y

Substitute x = -7y in 2x - 8y = 22

-14y - 8y = 22

Evaluate the like terms

-22y = 22

So, we have

y = -1

Recall that:

x = -7y

So, we have

x = -7(-1)

x = 7

So, the solution is (7, -1)

System 6

We have

-7x + 2y = 18

6x + 6y = 0

Make x the subject in 6x + 6y = 0

x = -y

Substitute x = -y in -7x + 2y = 18

7y + 2y = 18

Evaluate the like terms

9y = 18

Answer:

10 gallons

Step-by-step explanation:

Amy​'s car's maximum capacity to hold gas = 19 gallons

present amount of gas  = 9 gallons

As the car's capacity is 19 gallons and present amount in tank is 9 gallons, so we can fill it as much as so that the amount in tank becomes 19 gallons.

let assume she fills x gallons

then x gallons and 9 gallons present earlier should be equal to 19 gallon, as the tank can not hold more than that.

lets write it mathematically

x + 9 = 19

subtracting 9 from both side

x + 9 - 9 = 19 - 9

=> x = 10

Thus, 10 gallons of gas is needed to fill the gas tank.

The dimension of the rectangular of a norman window will be 1.6803*3.3606.

What is the area of Rectangle?

In any quadrilateral which have equal and parallel opposite sides is considered to be a rectangle. It is also called as a polygon with four sides and the four angles that are all 90 degrees each. A rectangle is a shape with only two dimensions. The product of the length and the breadth calculates its area. The length of the diagonals of any rectangle are equal in length. Thus, the length of the diagonals can be calculated easily using the Pythagoras theorem where, the diagonal is considered to be the hypotenuse.

Let r represents the radius, and b be the breadth.

Then, perimeter = 3.14*r+2r+2b = 12

For the dimension needed for the most light to enter we need to maximize the area.

Hence, area of the window : area of the semicircle + area of the rectangle

= \(\frac{3.14*r^2}{2} + 2rb\)

= \(12r - (\frac{3.14+4}{2}) r^2\)

A'(r) = 0

Therefore, \(r=\frac{12}{3.14+4}\) which is nearly equal to 1.6803m

From this value of r we can calculate the value of b to be;

b= 1.6803m

Thus, a= 3.606m

Thus the required dimension is : 1.6803*33606

Answer: \(230\)

Step-by-step explanation:

To find coterminal angles, add/subtract integer multiples of \(360^{\circ}\).

\(-490^{\circ}+360^{\circ}=-130^{\circ}\\\\-130^{\circ}+360^{\circ}=230^{\circ}\)

An angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘ is 130∘.

To find an angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘, we can use the concept of coterminal angles.

Coterminal angles are angles that have the same initial and terminal sides when drawn in standard position. To find a positive coterminal angle with a negative angle, we can add 360 degrees to the negative angle until we get an angle within the desired range (0∘ to 360∘).

Let's find the positive coterminal angle:

θ = -490∘ + 360∘

θ = -130∘

So, an angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘ is 130∘.

Answer:

Step-by-step explanation:

To dilate the square by a factor of 1111 from the origin, we need to multiply each coordinate by 1111.

The coordinates of point C are (8,8). So, to find the coordinates of point C' after dilation, we can simply multiply each coordinate by 1111:

x-coordinate of C' = 1111 * 8 = 8888

y-coordinate of C' = 1111 * 8 = 8888

Therefore, the coordinates of point C' are (8888, 8888).

We must find the zeros of the following function:

Now, the zeros of a function are the values of x when f(x) is equal to 0. So we must find all the values of x that makes f(x) = 0. To do that, it is convenient to rewrite the function f(x) as:

Where we use the fact that:

• (x + 3)² = (x + 3) (x + 3),

• (x² + 49) = (x + 7) (x - 7).

From the previous equation, we see that if we replace x with the following values, we get f(x) = 0:

• x = -3,

• x = 3,

• x = -7,

• x = 7.

Answer

All the real zeros of the function are -3, 3, -7, 7.

The temperature at x = 4, y = 3.2, estimated through linear interpolation from the given data points, is approximately 46.744.

To find the temperature at x=4, y=3.2 using linear interpolation, first of all, determine the values at the surrounding grid points and interpolate between them.

From the given table, we can identify the following surrounding points:

Point A: (x=4, y=3)

Point B: (x=4, y=4)

Point C: (x=6, y=3)

Point D: (x=6, y=4)

Next, interpolate along the x-axis at y=3 to find the temperature at x=4:

Temperature at x=4, y=3 = Interpolate(A, B)

Also, we have to interpolate along the x-axis at y=4 to find the temperature at x=4:

Temperature at x=4, y=4 = Interpolate(A, B)

Next, we'll interpolate between the temperatures obtained above along the y-axis at y=3.2:

Temperature at x=4, y=3.2 = Interpolate(Temperature at x=4, y=3, Temperature at x=4, y=4)

Let's calculate these values step by step:

Interpolate along the x-axis at y=3:

Temperature at x=4, y=3 = Interpolate(A, B)

= 80.00 + (4-4)/(4-4) * (80.00 - 80.00)

= 80.00

Interpolate along the x-axis at y=4:

Temperature at x=4, y=4 = Interpolate(A, B)

= 38.43 + (4-4)/(4-4) * (35.03 - 38.43)

= 38.43

Interpolate between temperatures along the y-axis at y=3.2:

Temperature at x=4, y=3.2 = Interpolate(Temperature at x=4, y=3, Temperature at x=4, y=4)

= 80.00 + (3.2-3)/(4-3) * (38.43 - 80.00)

= 80.00 - 0.8 * 41.57

= 80.00 - 33.256

= 46.744

Therefore, the temperature at x=4, y=3.2 is approximately 46.744.

The equation of a line in the slope intercept form is expressed as

y = mx + c

where

m = slope

c = y intercept

The given equation is expressed as

y = 7x/3 + 5

By comparing both equations, slope,m = 7/3

Recall, if two lines are parallel, it means that they have the same slope. This means that the slope of the line parallel to the given line is 7/3. Since the line passes through the point(- 9, 2), to find the y intercept of this line, we would substitute m = 7/3, x = - 9 and y = 2 into the slope intercept equation. We have

2 = 7/3 * - 9 + c

2 = - 21 + c

c = 2 + 21 = 23

The equation of the parallel line is

y = 7x/3 + 23

Recall, if two lines are perpendicular, it means that the slope of one line is equal to the negative reciprocal of the slope of the other line. This means that the slope of the line perpendicular to the given line is - 3/7. Since the line passes through the point(- 9, 2), to find the y intercept of this line, we would substitute m = - 3/7, x = - 9 and y = 2 into the slope intercept equation. We have

2 = - 3/7 * - 9 + c

2 = 27/7 + c

c = 2 - 27/7

c = - 13/7

The equation of the perpendicular line is

y = - 3x/7 - 13/7

The vertices of a rectangle are W(1, 2) X(4, 2) Y(4, 23) and Z(1, 23) Find the perimeter of the rectangle is 16.

We could use the distance formula to find the distance between the points in this problem, but when we look we see that the sides of the rectangle are parallel to the x and y-axis for each pair of sides. The first two points have a distance of 3 because 4-1=3. Since it is a rectangle, the opposite side will have the same length. For the sides perpendicular, we look at the points with the same x coordinate. Using (4,2) and (4,-3), we can calculate the length of the side by finding the distance by adding the absolute values of the y coordinate. 2+3=5. This means that the triangle has two sides with a length of 5 and two sides with a length of 3. Adding these together, 5+5+3+3 = 16.
