Which one of the following statements is true? a. if f is continuous on (a, b), then f attains an absolute maximum value and f attains an absolute minimum inside the interval (a, b). b. if f '(x) > 0 on the interval (a, b), then f is decreasing on the interval (a, b). c. if f and g are increasing on the interval (a, b), then f + g is increasing on (a, b). d. none of these are true.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
