rosijanka [135]

Answer:

15 customers were outside

Step-by-step explanation:

Represent customers inside with x and customers outside with y.

So, we have:

$x = \frac{1}{3}y - 2$ --- First Statement

$x = 3$ --- Second Statement

Required

Find y

Substitute 3 for x in $x = \frac{1}{3}y - 2$

$3 = \frac{1}{3}y - 2$

Add 2 to both sides

$2 + 3 = \frac{1}{3}y - 2 + 2$

$2 + 3 = \frac{1}{3}y$

$5= \frac{1}{3}y$

Multiply both sides by 3

$3 * 5= \frac{1}{3}y *3$

$15 = y$

$y = 15$

<em>Hence; 15 customers were outside</em>

Determine the slope of the line that passes through the points (-41, 15) and (-73, 15).

murzikaleks [220]

Slope formula = (y₂- y₁)/(x₂ - x₁) = m
The line passes through 2 points A( x₁, y₁) & B(x₂ y₂)
but we are given A( - 41, 15) & B(- 73, 15). NOW PLUG:

m = (15 - 15) / [( - 73 - ( -41)]
m= 0/(-32) & m =0
(when the slope = 0, this means the line is parallel to x=axis)
