If f(x) = -5x – 4 and g(x) = -3x - 2, find (f+ g)(x).
a. (f+g)(x) = 5x + 3x + 6
o

o
b. (f+g)(x) = -5* - 7x - 2
c. (f+ g)(x) = -5- 3x - 6
o
d. (f+ g)(x) = -8x- 6

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

me! what did you put for this question?

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
