Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (1, -5)

Point (7, -1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{-1+5}{7-1}$
Add/Subtract: $m=\frac{4}{6}$
Simplify: $m=\frac{2}{3}$

Simplify each expression. Use positive exponents. A^4b^-3 ab^-2

choli [55]

$\dfrac{a^4b^{-3}}{ab^{-2}}$

$= {a^{4-1}b^{-3+2}}$

$= {a^{3}b^{-1}}$

$= \dfrac{a^3}{b}$

Hey there! :D

The midpoint and the outside line are symmetrical to eachother, 2(BF)= AE

Two midpoint segments equals one AE segment.

So, use the representation above and plug in the numbers.

2(23)= 5x -4

56= 5x-4

Add 4 to both sides.

60=5x

Divide by the 5.

x=12

I hope this helps!

Answer:

D. Step 5

Step-by-step explanation:

Andrew made a mistake at last step.

It should be:

-11.8 + 9.8 = 9.8 - 11.8 = -2 but not -21.6
