Answer:

D.  4

Step-by-step explanation:

Given expression:

-2x^2-4x+10

To find the value of the expression when x = -3, substitute x = -3 into the expression:

\implies -2(-3)^2-(-3)x+10

Apply exponent rule  (-a)^2=a^2:

\implies -2(3^2)-4(-3)+10

\implies -2(9)-4(-3)+10

\implies -18-4(-3)+10

Apply rule -(-a)=a :

\implies -18+(4)(3)+10

\implies -18+12+10

Add/subtract from left to right:

\implies -6+10

\implies 4

Solve for x and y. What is m
irina [24]
3x + 2y + y - 3x = 180

3y = 180

y = 180/3

y = 60

3x = y - 3x

Let y = 60

3x = 60 - 3x

3x + 3x = 60

6x = 60

x = 60/6

x = 10

Answer: x = 10, y = 60
