Replace f(x) with 0. Then solve for x

f(x) = x^2 + 5x - 14
0 = x^2 + 5x - 14
x^2 + 5x - 14 = 0
(x+7)(x-2) = 0 ... factor (think of two numbers that multiply to -14 and add to 5)
x+7 = 0 or x-2 = 0
x = -7 or x = 2

The two zeros, roots, or x intercepts are x = -7 or x = 2

Answer: Choice C) {2, -7}

A company manufactures skateboards. Each skateboard requires 1 6/7 hours of labor to assemble and 2 1/2 hours of labor to finish
Assoli18 [71]

Answer: The total cost will be $156.85.

Step-by-step explanation:

Since we have given that

Time taken by labor to assemble the each skateboard is given by

1\frac{6}{7}\ hours\\\\=\frac{13}{7}\ hours

Time taken by labor to finish and stain each skateboard is given by

2\frac{1}{2}\ hours\\\\=\frac{5}{2}\ hours

Cost of labour to the company per hour = $36.00

According to question,

We will use "Distributive Property":

a\times (b+c)=a\times b+a\times c

36(\frac{13}{7}+\frac{5}{2})\\\\=36\times \frac{13}{7}+36\times \frac{5}{2}\\\\=\frac{468}{7}+18\times 5\\\\=\frac{468}{7}+90\\\\=\frac{468+630}{7}\\\\=\frac{1098}{7}\\\\=\$156.85

Hence, the total cost will be $156.85.
