1 answer:
pav-90 [236]3 years ago
8 0

Answer: A: 180= 90+4x+x

B: x=18

Step-by-step explanation:

1. Every triangle has a length of 180

2. So all the measurements combined would equal 180

3. So write the equation 180=90+4x+x

4. Let‘s simplfy, 180=90+5x

5. Subtract 90 from each side, 90=5x

6. Divide each side by 5, 18=x.

7. Double check our work! 90+(4*15)+18=180

The regression equation y = -0.414x + 106.55 approximates the percent of people in an
murzikaleks [220]

The correct option will be:   A. 67%

<em><u>Explanation</u></em>

Given equation is:   y = -0.414x + 106.55 , where x is the length of the film in minutes and y is the percentage of people finish watching the film.

Here, the length of the documentary is given as 95 minutes. So, we will <u>plug x=95 into the above equation</u> and get....

y=-0.414(95)+106.55\\ \\ y=-39.33+106.55\\ \\ y=67.22 \approx 67

<em>(Rounded to the nearest percent)</em>

So, the percentage of people in an audience who will finish watching a documentary that is 95 minutes long will be 67%

Ostrovityanka [42]

Answer: OPTION C.

Step-by-step explanation:

Given the following expression:

4x(3x- 7) - 19x^2

You can simplify this expression applying these steps:

First step: You must apply Distributive property:

=12x^2-28x-19x^2

Second step: You need to add the like terms.

Then, you get:

=-7x^2-28x

You can observe that this simplified expression matches with the expression provided in Option C.

Line e passes through points (7, 8) and (4, 10) Line f is parallel to line e. What is the slope of line f?
Tatiana [17]
<h3>Answer:  -2/3</h3>

==================================================

Explanation:

Use the slope formula to find the slope of line E

m = (y2-y1)/(x2-x1)

m = (10-8)/(4-7)

m = 2/(-3)

m = -2/3

The slope of line E is -2/3

The slope of line F is also -2/3 since parallel lines have equal slopes but different y intercepts.
