Answer:

$y=-\frac{1}{4} x-1$

Step-by-step explanation:

find the slope of the line using the two points (0,-1) and (4,-2)

$\frac{(-2+1)}{(4-0)} =-\frac{1}{4}$

since we already know that the y-intercept is -1 then you plug the numbers into the slope-intercept form y=mx+b and you get $y=-\frac{1}{4}x-1$

A fish tank holds 832 gallons but is leaking at a rate of 5 gallons per week. A second fish tank hose 1040 gallons but is leakin

OverLord2011 [107]

Answer:

Within 52 weeks, the amount of water in the two fish tanks will be the same.

Step-by-step explanation:

First, let's make the two equations equal to each other by placing an equal sign.

832 - 5x = 1040 - 9x

Now, that they are equal to each other, we can solve for x.

Okay, so we can move -5x to the other side by adding both sides with 5x.

832 = 1040 - 4x

Then, subtract 1040 from both sides to move it to the other side.

832 - 1040 = -208

-208 = -4x

Lastly, divide both sides by -4 to get the value of x.

-208/-4 = 52

x = 52
