Answer:
Step-by-step explanation:
Let's solve for f.
y=3x−2x2findf(3)
Step 1: Flip the equation.
−6df2inx2+3x=y
Step 2: Add -3x to both sides.
−6df2inx2+3x+−3x=y+−3x
−6df2inx2=−3x+y
Step 3: Divide both sides by -6dinx^2.
−6df2inx2
−6dinx2
=
−3x+y
−6dinx2
f2=
3x−y
6dinx2
Step 4: Take square root.
f=√
3x−y
6dinx2
or f=−√
3x−y
6dinx2
Answer:
f=√
3x−y
6dinx2
or f=−√
3x−y
6dinx2

Answer:
The expression would be 43x + 128
Step-by-step explanation:
43 dollars is multiplied by however many feet is used. Then, the exception(the gate) is added to the charge that is 43x
Answer:
$50
Step-by-step explanation:
Let x represent the cost of the cell phone.
Since the TV cost 5 times as much as the cell phone, its cost can be represented by 5x.
Since the computer cost 2.5 times as much as the TV, its cost can be represented by 12.5x.
Create an equation to represent the situation, and solve for x:
x + 5x + 12.5x = 925
18.5x = 925
x = 50
So, the cell phone cost $50
