Add 36 to each side of the equation.

Answers

Answer:

Option C is correct

Multiply both sides of the equation by (1)/(2)

Step-by-step explanation:

Given the equation:

2x^2+12x = 32

Multiply both sides by (1)/(2)  we get;

(1)/(2) \cdot (2x^2+12x) = (1)/(2) \cdot 32

Simplify:

x^2+6x = 16

Subtract 16 from both sides we have;

x^2+6x-16=0

Therefore, the first step to solve the equation by completing the square is,

Multiply both sides of the equation by (1)/(2)
Multiply both sides of the equation by 1/2

Write a linear equation to represent the line shown on the graph

Answers

The linear equation representing the line passing through the points (0, 4) and (2, -2) is y=−3x+4.

Here, we have to write a linear equation that represents the line passing through the points (0, 4) and (2, -2), we can use the point-slope form of a linear equation:

y - y_1 = m(x- x_1)

where:

m is the slope of the line,

(x_1,y_1)is one of the given points on the line.

Given the points (0, 4) and (2, -2),

let's calculate the slope m:

m= −2−4/ 2−0

 = −6/2

 =−3.

Now, use the point-slope form with the point (0, 4):

y−4=−3(x−0).

Simplify the equation:

y−4=−3x.

Add 4 to both sides:

y=−3x+4.

So, the linear equation representing the line passing through the points (0, 4) and (2, -2) is y=−3x+4.

Answer:

y=-3x+4

Step-by-step explanation:

it's negative bc the slope is going from left to right. you just have to do rise over run to find the slope.

Solve this equation: –9h – 6 + 12h + 40 = 22. A. h = 24 B. h = – 4 C. h = 4 D. h = –4/7

Answers

In the equation: -9h - 6 + 12h + 40 = 22, collecting like terms gives: -9h + 12h = 22 + 6 - 40 which gives 3h = -12. They we divide both sides of the equation by 3 to get 3h / 3 = -12 / 3 which gives h = -4. Therefore, the solution to the given equation is h = -4 (option B).

You are standing 44 meters from the base of a building. You estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82°. If the total height of the building is another 121meters above the 86th floor, what is the approximate height of the building? (Round your answers to one decimal place.)
meters
One of your friends is on the 86th floor. What is the distance between you and your friend?
meters

Answers

The height of the building is 313 m while the friend is 192 m above me.

What is the angle of elevation?

The angle of elevation is the angle between the horizontal plane and the line of sight or upward direction to an object or point of interest. It is typically measured in degrees, minutes, and seconds.

The angle of elevation is commonly used in trigonometry, surveying, and navigation to determine the height or distance of an object.

Let the distance from the ground frond to the 86th floor be x

We would now have that;

Tan 82 = 121 + x/44

44Tan 82 = 121 + x

313 = 121 + x

x = 313 - 121

x = 192 meters

Total height of the building = 192 m + 121 m = 313 m
