3⁄2 c + 23 = 38<br><br> can you help me find out what c is pretty please
kolbaska11 [484]

Answer:

C=10

Step-by-step explanation:

To solve this problem, first, you have to isolate it on one side of the equation. Remember, isolate c on one side of the equation.

3/2c+23-23=38-23 (subtract 23 from both sides.)

38-23 (solve.)

38-23=15

3/2c=15

2*3/2c=15*2 (multiply 2 from both sides.)

15*2 (solve.)

15*2=30

3c=30

3c/3=30/3 (divide by 3 from both sides.)

30/3 (solve.)

30/3=10

c=10

Evaluate:-19 - (-10) + (20) - (30) - (-15)<br> A) -4 <br> B) -3 <br> C) 3 <br> D) 4
Tresset [83]

So firstly, remember that <u>subtracting a negative number is the same as adding a positive number</u> so our expression will look like this:

-19+10+20-30+15

Now solve as such:

\underbrace{-19+10}_{-9}+20-30+15\\\\\underbrace{-9+20}_{11}-30+15\\\\\underbrace{11-30}_{-19}+15\\\\\underbrace{-19+15}_{-4}\\\\-4

<u>Your answer is -4, or A.</u>

Let f(x) = 2x2 + x − 3 and g(x) = x + 2.<br><br> Find (f • g)(x)
katen-ka-za [31]

Answer:

(f\cdot g)(x) =  2x^3 + 5x^2-x-6

Step-by-step explanation:

We are given the two functions:

f(x)=2x^2+x-3\text{ and } g(x)=x+2

And we want to find:

(f \cdot g)(x)

Recall that this is equivalent to:

=f(x)\cdot g(x)

Substitute. Hence:

(f\cdot g)(x)= (2x^2+x-3)(x+2)

Expand if desired:

\displaystyle = x(2x^2+x-3)+2(2x^2+x-3) \\ \\ = (2x^3+x^2-3x)+(4x^2+2x-6) \\ \\\ = 2x^3 + 5x^2-x-6
