Steps to solve:
f(x) = 3x³ – 2x² + x; x = -3
~Substitute
f(-3) = 3(-3)³ - 2(-3)² + (-3)
~Solve the exponents
f(-3) = 3(-27) - 2(9) + (-3)
~Multiply
f(-3) = -81 - 18 - 3
~Subtract
f(-3) = -102

3/4 * h = 2 1/4
3/4* h * 4/3 = 9/4 * 4/3
h = 3
Answer:
x=0, y=-12
Step-by-step explanation:
you can use substitution to solve for x
-3(x-12)=2x+36
-3x+36=2x+36
subtract 36 from both sides and add 3x to both sides
0=5x
x=0
now plug in 0 as x for either equation
y=0-12
y=-12
to check your work plug in x and y into the other equation
-3(-12)=2(0)+36
36=36

Answer:
x=-2
Step-by-step explanation:
2(3x – 1) = 4x - 6
Distribute
6x-2=4x-6
Moving like terms (4x)
2x-2=-6
Moving like terms (-2)
2x=-4
Divide both sides by 2 to isolate x
x=-2
