Answer:
4x3=12
Step-by-step explanation:
<span>+2x- 2y + 3z =-4
2(-3) - 2(-7) + 3(-4) = -4
-6 + 14 - 12 = -4
-18 + 14 = -4

Answer:
t=-3.7
Step-by-step explanation:
Let's solve your equation step-by-step.
5(t+3)=−3.5
Step 1: Simplify both sides of the equation.
5(t+3)=−3.5
(5)(t)+(5)(3)=−3.5(Distribute)
5t+15=−3.5
Step 2: Subtract 15 from both sides.
5t+15−15=−3.5−15
5t=−18.5
Step 3: Divide both sides by 5.
5t/5=-18.5/5
t=-3.7
The domain is all real numbers and the range is all the reals at or above the vertex y coordinate (if the coefficient on the squared term is positive) or all the reals at or below the vertex (if said coefficient is negative).
