Hope this helps
Step-by-step explanation:
Let's solve your equation step-by-step.
4x+2=2x+12
Step 1: Subtract 2x from both sides.
4x+2−2x=2x+12−2x
2x+2=12
Step 2: Subtract 2 from both sides.
2x+2−2=12−2
2x=10
Step 3: Divide both sides by 2.
2x

Answer:
C)
f(–3) = 9
Step-by-step explanation:
Given f(x) = 4x^4 + 5x^3 – 15x^2 – 45
f(-3) means let x = -3
f(-3) = 4(-3)^4 +5(-3)^3 – 15(-3)^2 – 45
=4(81) +5(-27) -15(9) -45
= 324 - 135 - 135 -45
=9
Answer:
We need to find the unit rates for the fruit. To do this, divide the cost by the number of pounds
Grapefruit:
cost/pounds
$3/6 pounds
3/6=0.5
0.5 per pound
Apples:
cost/pounds
$2.65/5 pounds
2.65/5=0.53
0.53 per pound
