If f(x) = 2x – 5 and g(x) = 5x – 2, what is f · g?

A.
f(x) · g(x) = 10x2 – 29x + 10

B.
f(x) · g(x) = 10x + 10

C.
f(x) · g(x)= 7x – 7

D.
f(x) · g(x) = 10x*2 + 29x – 10

The answer is option A.

Step-by-step explanation:

f(x) = 2x – 5

g(x) = 5x – 2

f(x). g(x) = (2x - 5) ( 5x - 2)

= 10x² - 4x - 25x +10

= 10x² - 29x + 10

Hope this helps

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
