Answer:

y = -2x + 4

Step-by-step explanation:

Two points on this line are (2,0) and (0,4). Moving from (0,4) to (2,0), x increases by 2 and y decreases by 4. Thus, the slope of this line is m = -4/2, or m = -2.

Thus, the equation of this line is y-0 = (-2)(x - 2), or y = -2x + 4.

The equation for a line with a y-intercept of 4 and a x-intercept of 2 is y = -2x + 4 where -2 is the slope and 4 is the y-intercept.

Steps:

37-(x+8)=32

Subtract 37 from both sides

37-(x+8)-37=32-37

Simplify

-(x+8)=-5

Divide both sides by -1

-(x+8)/-1=-5/-1

Simplify

x+8=5

Subtract 8 from both sides

x+8-8=5-8

Simplify

x=-3

The Golden Years Senior Citizen Center uses a phone tree to announce when the center will be closed for poor weather. When each

stira [4]

Answer:

50 Minutes.

Step-by-step explanation:

The function c approximates the total number of calls made after m minutes since the start of the phone tree.

$c(m)=\frac{2}{3}\times (3^{\frac{m}{10}}-1)$

We need to find the number of minutes after which the total number of calls will 363.

Substitute c(m)=363 in the given function.

$363=\frac{2}{3}\times (3^{\frac{m}{10}}-1)$

Multiply 3/2 both sides.

$363\times \frac{3}{2}=(3^{\frac{m}{10}}-1)$

$242=3^{\frac{m}{10}}-1$

Add 1 on both sides.

$243=3^{\frac{m}{10}}$

$3^5=3^{\frac{m}{10}}$

On comparing both sides we get

$5=\frac{m}{10}$

Multiply both sides by 10.

$50=m$

Therefore, the total number of calls will 363 after 50 minutes since the start of the phone tree.
