Apair of 120 shoes was discounted 20 percent a costumer had a coupon for an additional 5 off what was the final price of the shoes ?

The final price of the shoes is $91.20.  

Step-by-step explanation:

In order to find the final price of the shoes, we need to calculate each discount separately.  Since the initial cost of the shoes is $120, we need to first find the cost after the 20% discount.  If the shoes are discounted 20%, then we can find the cost by multiplying the original amount by 80%, or 0.8:  $120 x 0.80 = $96.00.  Since the customer also has an additional 5% off with the coupon, we can then take the new total, $96.00, and multiply by 95%, or 0.95, to get the final cost:  $96.00 x 0.95 = $91.20.  

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
