the angles on the opposite sides of a quadrilateral touching the circumference adds up to 180 degrees

so,

(21x-2) + (38x +5) = 180

21x+38x −2+5=180

59x+3=180

59x=177

x=3

What is the equation for this graph’s lone of best fit. <br> this is due today pls help
Natasha2012 [34]

Answer:

I don't know if your question is multiple choice or not but here's a close estimate to what it should be.

y = \frac{3}{4} x  

Step-by-step explanation:

Obviously at a drop of 0 height there would be 0 rebound height so your y-intercept has to be 0.

As for the slope of the line I used the point at 2.5 and 3.

Here are the coordinates (2.5, 1.25) and (3, 1.625)

Find the average rate of change as you see below

1.625 - 1.25 = .375

3 - 2.5 = .5

.375 / .5 = .75 or 3x/4

The points aren't exactly on the line and the graph isn't 100% linear so obviously the equation is not 100% precise. The slope should very close to 0.75 or 3/4.

X<br> (2x - 7)^3= (2x)^3- 7^3<br> = 8x3 - 343
emmainna [20.7K]

Answer:

(2x - 7)³ ≠ (2x)³- 7³

Step-by-step explanation:

(2x - 7)³= (2x)³- 7³

Use pascal's triangle to expand left side. Simplify all else.

(2x)³ + 3(2x)²(-7)¹ + 3(2x)¹(-7)² + (-7)³ = 8x³- 343

8x³ + 3(4x²)(-7) + 3(2x)(49) + (-7)³ = 8x³- 343

8x³ - 84x² + 294x - 343 = 8x³- 343
