Answer:

no \: solution

Step-by-step explanation:

1) Expand.

7a + 5a + 15 = 8a + 4a+ 8

2) Simplify 7a + 5a + 15 to 12a + 15.

12a + 15 = 8a + 4a+ 8

3) Simplify 8a + 4a + 8 to 12a + 8.

12a + 15 = 12a + 8

4) Cancle 12a from both sides.

15 = 8

5) Since 15 = 8 is false, there's no solution.

no \: solution

Therefor, this equation has no solution.

Find f. f ''(x) = −2 + 36x − 12x2, f(0) = 8, f '(0) = 18 f(x) =
Alik [6]
Integrate <span>f ''(x) = −2 + 36x − 12x2 with respect to x:

f '(x) = -2x + (36/2)x^2 - (12/3)x^3 + c.  Find c by letting x = 0 and using f(0)=8.

Then f '(0) = -2x + 18x^2 - 4x^3 + c = 18 (which was given).

Then             -0      + 0      - 0 + c = 18, so c = 18 and 

f '(x) = </span>-2x + 18x^2 - 4x^3 + 18.

Go through the same integration process to find f(x).

Some one plz help meh I need to understand and I dont
vfiekz [6]

Answer:

It's asking you to find the inputs of the function.

Step-by-step explanation:

Basically, when you input something, you replace "x" in the equation with the number you want to input. For example, if I had the equation: 5x/6+5, then I wanted to input "5", then 5 would replace x in the equation, making 5(5)/6+5. The output they are giving you is simply evaluating the equation that you used to input x, so basically in the case I gave you, the output would be 5(5)/6+5, or 25/6+5, and 55/6. Using the outputs, they want you to find the inputs.
