If ƒ(x) = 15x + 7 and g(x) = x2 – 5x, find (ƒ + g)(x). a. (ƒ + g)(x) = x2 + 10x +7 b. (ƒ + g)(x) = 15x2 – 75x +7 c. (ƒ + g)(x) = 15x + g + 7 d. (ƒ + g)(x) = 15x3 – 68x2 – 35x

x² + 10 x + 7 → A

(f + g)(x) = f(x) + g(x) = 15x + 7 + x² - 5x = x² + 10x + 7

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
