A=πr²
πr²= 64π
Subtract the from both sides

Square root both sides

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\
m=\dfrac{2-(-3)}{-1-6}\\
m=\dfrac{5}{-7}\\
m=-\dfrac{5}{7}\\$

Answer:

0.74

Step-by-step explanation:

We can isolate x, getting 9.2x - 1.9x = -1 + 6.4

We can then simplify, getting 7.3x = 5.4, which we can solve by dividing both sides by 7.3:

x = 5.4 / 7.3 = 0.74

I believe it is 8 because $EF= \frac{AB+CD}{2} = EF= \frac{5+11}{2} =8$

C. 4x + y = 21

4(3) + 9 = 21
12 + 9 = 21
21 = 21
