Answer:

x=8

Step-by-step explanation:

Distribution Property: multiply -9+x into -10

-10(-9+x)= 90-10x

90-10x=10

Put alike numbers together.

\(\frac{90}{-90}\)-10x= \(\frac{10}{-90}\)

-10x=-80

Divide to get x.

-10x=-80

\(\frac{-10x}{-10} = \frac{-80}{-10}\)

x= 8

Answer:

Total cost: 486.080$

Step-by-step explanation:

Original Price: 560.000$

Sale: 20%

Discount: 560.000$ * 20% = 112.000$

Discounted Price: 560.000$ - 112.000$ = 448.000$

Tax Rate: 8.5%

Tax: 448.000$ * 8.5% = 38.080$

Tax after Tax: 448.000$ + 38.080$ = 486.080$

In this section we will discuss the method of graphing an equation in two variables. In other words, we will sketch a picture of an equation in two variables.

Step-by-step explanation:

The pair of 1st line is vertical opposite angle and 2nd one is adjacent angles.

What is vertical opposite angle ?

When 2 lines meet one another, then the other angles, shaped thanks to intersection ar known as vertical angles or vertically opposite angles. A try of vertically opposite angles ar continuously adequate to one another. Also, a angle and its adjacent angle are supplementary angles, i.e., they add up to a hundred and eighty degrees.

Main body:

1st pair of line intersect each other , so ∠1 = ∠2 by using vertical opposite angle.

2nd pair of line also intersect each other , so ∠3 ,∠4 are adjacent angles.

Hence ,pair of 1st line is vertical opposite angle and 2nd one is adjacent angles.

The slope of the secant line PQ, when x = 4.1, is approximately 9.6.

To find the slope of the secant line PQ, we need to determine the coordinates of point Q and then calculate the difference in y-coordinates divided by the difference in x-coordinates.

Given that Q has coordinates (x, x²+x+3), when x = 4.1, we can substitute this value into the equation to find the y-coordinate of Q.

For x = 4.1:

y = (4.1)² + (4.1) + 3

 = 16.81 + 4.1 + 3

 = 23.91

So the coordinates of Q are (4.1, 23.91).

The slope of the secant line PQ is calculated by taking the difference in y-coordinates divided by the difference in x-coordinates:

slope = (23.91 - 23) / (4.1 - 4)

     = 0.91 / 0.1

     ≈ 9.1

Therefore, when x = 4.1, the slope of the secant line PQ is approximately 9.1.

YOU SUBTRACT -4 ON BOTH SIDES SO YOU'LL GET X= 1/4

Answer:

x= 1/4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(3/2)(2)+(3/2)(−6x)+1=3+−5x (Distribute)

3+−9x+1=3+−5x

(−9x)+(3+1)=−5x+3 (Combine Like Terms)

−9x+4=−5x+3

−9x+4=−5x+3

Step 2: Add 5x to both sides.

−9x+4+5x=−5x+5x+3

−4x+4=3

Step 3: Subtract 4 from both sides.

−4x+4−4=3−4

−4x=−1

Step 4: Divide both sides by -4.

Not all possible values of the domain may be covered by an operation's definition. For instance, it is impossible to square the roots of negative numbers or divide by zero in real numbers. An operation's domain of definition, also known as the active domain, is the set of values for which the operation is specified. However, the set of real values obtained by the operation is its codomain of definition, active codomain, image, or range. The set that contains the values created is referred to as the codomain. For instance, only non-negative numbers are produced by the squaring operation when applied to the real numbers; the set of real numbers is the codomain, but the non-negative numbers are the range.

The radius of the cone is 783.84/√h

A cone is the surface traced by a moving straight line (the generatrix) that always passes through a fixed point (the vertex).

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.

The volume of a cone is expressed as;

V = 1/3πr²h

643072 × 3 = 3.14 × r²h

r²h = 614400

r² = 614400/h

r = 783.84/√h

Answer:

10 m and 60 m.

Step-by-step explanation:

Perimeter = 140 m

Area = 210 \(m^{2}\)

Distance between pair of opposite sides = height of the parallelogram = 7 m

Area of parallelogram = \(\frac{1}{2}\) x base x height

210 = \(\frac{1}{2}\) x base x 7

420 = 7 x base

base = \(\frac{420}{7}\)

         = 60 m

The base of the parallelogram is 60 m, which is equal to the length of the opposite side.

Perimeter = 2(a + b)

140 = 2 (a + 60)

140 = 2a + 120

2a = 140 - 120

2a = 20

a = 10 m

Thus, the length of two adjacent sides of the parallelogram are; 10 m and 60 m.

Step-by-step explanation:

The difference in the values of the two cars when they are each 7 years old is equal to $6,000.

In order to determine the difference in the values of the two cars, we would have to write an equation that models the price of the cars after a length of time, by using the data points shown in the graph above.

Mathematically, the slope of any straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

For Car A, we have:

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (9 - 12)/(4 - 2)

Slope, m = -3/2

Slope, m = -1.5

At point (4, 9), a linear equation for car's value can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

Where:

Substituting the given points into the formula, we have;

y - y₁ = m(x - x₁)

y - 9 = -1.5(x - 4)

y = -1.5x + 15

In 7 seven years, the value of Car A is given by:

y = -1.5x + 15

y = -1.5(7) + 15

y = $4,500

Note: The negative sign indicates that the value of the car is depreciating.

For Car B, we have:

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (10 - 18)/(5 - 1)

Slope, m = -8/4

Slope, m = -2

At point (5, 1), a linear equation for car's value can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

y - 1 = -2(x - 5)

y = -2x + 11

In 7 seven years, the value of Car B is given by:

y = -2x + 11

y = -2(7) + 3.5

y = $10,500

Now, we can determine the difference as follows:

Difference = $10,500 - $4,500

Difference = $6,000.
