Answer:

c = -5

Step-by-step explanation:

Plug in -5 to c in the equation:

c² - 25 = 0

(-5)² - 25 = 0

Simplify. First, solve the power, then solve the subtraction:

(-5)² - 25 = 0

(-5 * -5) - 25 = 0

(25) - 25 = 0

0 = 0 (True)

Answer:

c=-5

Step-by-step explanation:

c^2-25=0

I'm going to solve this by using square root after I get the square termed by itself.

$c^2-25=0$

Add 25 on both sides:

$c^2=25$

Square root both sides:

$c=\pm \sqrt{25}$

$c=\pm 5$

Check!

$(5)^2-25=0 \text{ and } (-5)^2-25=0$

Answer:

Step-by-step explanation:

I think below is your full question:

Erin and Dan went shopping at their local store. Erin bought shirts that cost $12 each and spent $18 on accessories. Dan bought the same number of shirts as Erin for $16 each and spent $10 on accessories.

If Erin and Dan were billed the same amount by the store, how many shirts did each of them buy?

Here is my answer

Let x is number of shirts

Person COST

ERIN 12x+18

DAN 16x+10

Equally Billed 12x+18=16x+10 <=> x = 2

so each of them buy 2 shirts

How do you find the slope (m) and the y-intercept for (0,-4), (5,-4)?

navik [9.2K]

Answer:

In order to find the slope (m), and the y-intercept of this coordinate pair, you must complete rise over run.

This is represented by y2-y1, x2-x1. This can be represented like so:

-4-0 = -4

5--4 = 9

Here, we have concluded that our slope is -4/9.

Now, we must convert this into point slope form. Point slope form is y-y1=m(x-x1). This will look like this in our situation:

y+4=-4/9(x-0)

To solve, distribute the -4/9 first, which will leave you with:

y+4=-4/9x+0

Now, subract the 4 to both sides of the equation.

Our final answer looks like: y=-4/9-4.

-

SLOPE: -4/9

Y INTERCEPT: -4
