Answer:

the second option: \(7x+4y=44\)

Step-by-step explanation:

So when a line is parallel, it means that it has the same slope and a different y-intercept, it's important that there is a different y-intercept, otherwise it would be the same line, and the "two lines" would intersect at infinite points.

Anyways by looking at the graph you have two points (-8, 5) and (-4, -2). So the run in this case was 4 and the rise was -7. This is a slope of -7/4. So we have the equation: \(y=-\frac{7}{4}x+b \text{ where b}\ne-9}\). Since it passes through the point (8, -3) we can plug that in as (x, y) to solve for b (the y-intercept)

Plug in (8, -3) as (x, y)

\(-3=-\frac{7}{4}(8)+b\)

Multiply the -7/4 and 8

\(-3 = -14+b\)

add 4 to both sides

\(11 = b\)

So this gives us the equation:

\(y=-\frac{7}{4}x+11\)

Since it's asking for it in standard form you move the 7/4 x to the other side

Add 7/4x to both sides

\(\frac{7}{4}x+y=11\)

Multiply both sides by 4 to cancel out the fraction

\(7x+4y=44\)

The equation r-6=0 is given in the cylindrical coordinates. The shape of this equation is not a sphere; it is a cylindrical shell. This equation is a cylindrical shell rather than a sphere.

Therefore, the given statement, "The shape of this equation is a sphere" is FALSE.

Cylindrical coordinates (r, θ, z) are a coordinate system that defines a point in three-dimensional space. It is similar to the polar coordinate system, except that the z-axis is added, resulting in the use of a cylindrical surface to specify the point location.

Let's find the solution.The cylindrical coordinate system is a three-dimensional coordinate system that is defined by the distance from a point in the xy-plane to a fixed point known as the origin, the angle that the point makes with the x-axis, and the vertical height of the point from the xy-plane, which is referred to as the z-coordinate of the point.

When defining a point in three-dimensional space, cylindrical coordinates are commonly used.

A sphere is a three-dimensional object with a curved surface that is equidistant from a single point in space. A spherical coordinate system is often used to specify the position of a point on a sphere. A cylindrical coordinate system, on the other hand, is commonly used to specify the position of a point on a cylindrical shell.

The equation

r - 6 = 0

is given in cylindrical coordinates. This equation is a cylindrical shell rather than a sphere.

Therefore, the given statement, "The shape of this equation is a sphere" is FALSE.

The triangle with sides 25cm, 5cm and 24cm is not a right triangle.

Now, According to the question:

Let us assume that :

ABC is a right triangle,

A = 25cm

B = 5 cm

C = 24 cm

We have to find if the given sides of a triangle form a right triangle.

By using Pythagoras theorem for a right triangle,

\(A^2 = B^2+C^2\)

\((25)^2 = (5)^2 + (24)^2\)

LHS:\((5)^2 + (24)^2\)

= 25 + 576

= 601

RHS:\((25)^2\)

= 625

LHS ≠ RHS

Since, the Pythagorean theorem does not apply, the given sides do not form a right triangle.

Therefore, the triangle with sides 25cm, 5cm and 24cm is not a right triangle.

The general pattern of An is: An = 12(1 +* (*)) + (n-1)*(12*(*)(*) - 33.14). To find the general pattern of An, we can observe that each term is obtained by adding a constant multiple of the previous term with a fixed value.

Based on the given information, we can calculate the value of A2 as follows:
A2 = Ap+* (*)
  = A1+* (*)
  = [12(1 +* (*))] + (*)
  = 12 + 12*(*)(*)
So, we can write the general formula for An as:
An = A1 + (n-1)*d
where d is the common difference between consecutive terms. To find the value of d, we can subtract the first term from the second term:
d = A1 - Ao
 = [12(1 +* (*))] - 13 13 3 13 + 3.14 4 4
 = 12 + 12*(*)(*) - 13 - 13 - 3 - 13 - 3.14 - 4
Simplifying the above expression, we get:
d = 12*(*)(*) - 33.14
So, the general pattern of An is:
An = 12(1 +* (*)) + (n-1)*(12*(*)(*) - 33.14)

The numbers are 2,5,8

Step-by-step explanation:

1320/6=220

1350/6=225

1380/6=230

These numbers are all divisible by 6.

The possible digits that would make the number divisible by 6 are 2 , 5 and 8.

We know that any number must be divisible by 6 if the number is an even number and divisible by 3.

Now the given number is 13...0.

Since the last digit is 0, hence it is an even number.

Now for the number divisible by 3, the sum of the digits must be divisible by 3.

let the missing digit be a such that 6 is factor of 13a0

Therefore the number is 13a0.

Sum of the digits = 1+3+a +0 = 4+a

Now the value of a can be 2 then sum is 6, hence divisible.

The value of a can be 5 then sum is 9, hence divisible.

Also the value can be 8 then sum is 12 hence divisible.

Therefore the required complete numbers are :

1320/6=220

1350/6=225

1380/6=230

Hence the required digits are 2,5 and 8.

Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon.

Regular and irregular polygons

Interior angles of polygons

To find the sum of interior angles in a polygon divide the polygon into triangles.

Irregular pentagons

The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°.

Example

Calculate the sum of interior angles in a pentagon.

A pentagon contains 3 triangles. The sum of the interior angles is:

180 * 3 = 540

The number of triangles in each polygon is two less than the number of sides.

The formula for calculating the sum of interior angles is:

(n - 2) * 180  (where n is the number of sides)

The value of x is (5t-a) when the formula is 6x+a=5(x+t).

According to the question,

We have the following information:

6x+a=5(x+t)

Now, from this formula, we have to mark the value of x or in other words, we have to find the value of x.

Now, multiplying 5 into the bracket on the right hand side:

6x+a = 5x+5t

Subtracting 5x from both sides of the equation:

6x-5x+a = 5t

x+a = 5t

Subtracting a from both sides of the equation, we will get the final value of x in terms of t and a:

x = 5t-a

Hence, the value of x is (5t-a) when the formula is 6x+a=5(x+t).

The values in between can be obtained by adding 3 to the previous food coupon value and adding 5 to the previous raffle ticket value. Based on the given information, we know that each donor pack contains 3 food coupons and 5 raffle tickets.

We can complete the double number line by considering the relationship between the number of food coupons and the number of raffle tickets.

Starting with the given values:

Food coupons: 0

Raffle tickets: 0

We can increment both values by the same amount to maintain the ratio of 3 food coupons to 5 raffle tickets. Adding 3 to the food coupons and 5 to the raffle tickets, we get:

Food coupons: 3

The required cost of the meal given as a hot dog is of $6 and the hamburger is of $8.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Let's call the cost of a hot dog meal "x" and the cost of a hamburger meal "y".

From Mrs. Hammond's purchase, we know that:

x + 3y = 30   -- - - - - -(1)

From Mr. Weber's purchase, we know that:

3x + 3y = 42 - - - - - -(2)

We can use substitution to solve for one of the variables in terms of the other. If we substitute the first equation into the second equation:

3x + 3y = 42

3x + 3(30 - x)/3 = 42

3x + 30 - x = 42

2x = 12
x = 6

now,
6 + 3y = 30
3y = 24
y = 8

The blanks are filled as follows

Step one

Equation 2x + y = 18 Isolate y,

y = 18 - 2x

Step Two:

Equation 8x - y = 22, Plug in for y

8x - (18 - 2x) = 22

Step Three: Solve for x by isolating it

8x - (18 - 2x) = 22

8x - 18 + 2x = 22

8x + 2x = 22 + 18

10x = 40

x = 4

Step Four: Plug what x equals into your answer for step one and solve

y = 18 - 2x

y = 18 - 2(4)

y = 18 - 8

y = 10
