Answer:
6
Step-by-step explanation:

Answer:
x=4
ME=9
AM=18
AE=27
Because m in the midpoint ME is double AM
2(4x-7)=5x-2 4(4)-7 5(4)-2 18+9
8x-14=5x-2 16-7 20-2 =27
<u>-5x -5x</u> =9 =18
3x-14=-2
<u> +14 +14</u>
<u>3x</u>=<u>12</u>
3 3
x=4
Answer:
57?
Step-by-step explanation:
Answer:
-720
Step-by-step explanation:
We are given the expression:

and asked to evaluate when x= -2 and y= -3.
Therefore, we must substitute -2 for x and -3 for y.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Evaluate the first exponent.
⇒ (-2)³ = -2 * -2 * -2= 4*-2= -8

Evaluate the second exponent.
⇒ (-3)²= -3 * -3= 9

Multiply 10 and -8.

Multiply -80 and 9.

The value of 10x³y² at x= -2 and y= -3 is -720
