Answer:
h[j(3)] = -20
Step-by-step explanation:
We need h(j(3)). First find j(3)
j(x) = -x, so
j(3) = -(3) = -3
Now find h(-3)
h(x) = 4x - 8, so
h(-3) = 4(-3) - 8
h(-3) = -12 - 8 = -20
So h[j(3)] = -20
Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
75+50x=25+70x
Step 1: Simplify both sides of the equation.
50x+75=70x+25
Step 2: Subtract 70x from both sides.
50x+75−70x=70x+25−70x
−20x+75=25
Step 3: Subtract 75 from both sides.
−20x+75−75=25−75
−20x=−50
Step 4: Divide both sides by -20.
−20x
−20
=
−50
−20
x= 5/2
