For this, plug in 4 into the x placeholder to solve:

f(4)=2*4^2+4*2-7\\ f(4)=2*16+8-7\\ f(4)=32+8-7\\ f(4)=33

<u>In short, f(4) = 33.</u>

What is the sum of 2x^2 and 2x^3
jeyben [28]

For this case we have the following expression:

2x ^ 2 + 2x ^ 3

The terms are not similar, so they cannot be added.

<em>Examples of similar terms:</em>

x ^ 3 + x ^ 3 = 2x ^ 3\\3x ^ 4 + 2x ^ 4 = 5x ^ 4

Then, the expression given can only be rewritten as:

2 (x ^ 2 + x ^ 3)

This is taking common factor 2 to both terms.

Answer:

2 (x ^ 2 + x ^ 3)

Write the equation of a line that is parallel to the line-y=-x+6
Ostrovityanka [42]

Answer:

y=x-5

Step-by-step explanation:

y=mx+b

if lines are parallel then that means the slope (m) is the same so the only thing left to change is the y-intercept (b). this can be anything but probably shouldn't be what the original was

During a stretch of 5 games, Stephen Curry averaged 42 points per game. In his first 4 games he scored 45, 48, 32, and 40 points
makkiz [27]
First, I will add up the know amount of points Chef Curry scored
45 + 48 + 32 + 40 = 165
To find the mean, add up all the numbers and divide that by how many values you had
I know 210 / 5 = 42, so I will subtract:
210 - 165 = 45
Cheer Curry scored 45 points
