A manufacturing company with 450 employees begins a new product line and must increase their number of employees by 18 percent.

Tcecarenko [31]

Answer:

531 employees

Step-by-step explanation:

A manufacturing company with 450 employees begins a new product line and must increase their number of employees by 18 percent. Note that

450 employees - 100%

x employees - 18%.

Mathematically, you can write proportion:

$\dfrac{450}{x}=\dfrac{100}{18},\\ \\x=\dfrac{450\cdot 18}{100}=81.$

The new number of employees is

$450+81=531.$

2. Write an equation of a line in slope-intercept form

Alona [7]

Answer:

$y = -3x + 6$

Step-by-step explanation:

$m = -3\\(4,-6)\\x = 4\\y = -6\\m = \frac{y-y_1}{x-x_1} \\-3 = \frac{y -(-6)}{x-4} \\-3 =\frac{y+6}{x-4} \\Cross-Multiply\\-3(x-4) = y+6\\-3x+12=y+6\\-3x+12-6=y\\-3x+6 = y\\y =-3x+6$
