Step-by-step explanation:

2. 40% of x = 35

a. Equation = 0.4x = 35

b.

35 / 4 = 8.75

8.75 x 10 = 87.5

Check:

87.5 * 0.4 = 35

3. Priya has completed 9 questions which is 60% of the entire test.

a. Equation = 0.6x = 9

b.

9 / 6 = 1.5

1.5 x 10 = 15

15 questions

Check:

0.6(15) = 9

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
