Ashley and Robbin bought identical backpacks at different stores. Ashley’s backpack originally cost $65 and was discounted 25%.
miskamm [114]

Answer:

Ashley’s backpack is the better buy.

Step-by-step explanation:

You have to calculate the price that was paid for each backpack after the discount was applied.

Ashley’s backpack: $65*0.25= $16.25

Final price= $65-$16.25= $48.75

Robbin's backpack: $75*0.3= $22.5

Final price= $75-$22.5= $52.5

According to this, the backpack that is the better buy is the one that Ashley bought because after the discounts were applied it cost $48.75 and Robbin's backpack cost $52.2 which means that Ashley's backpack was cheaper.

Find the slope-intercept equation for the line with the indicated slope and y-intercept. Slope 1/4; y-intercept (0, -4)
Ilya [14]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have the slope m = 1/4 and y-intercept (0, -4) → b = -4.

Answer: y=\dfrac{1}{4}x-4

The expression (y^20) (y^-5)^2 is equivalent to y^n. What is the value of n? n = 27 n = 10 n = -200 n = 17
belka [17]

Answer:

n = 10

Step-by-step explanation:

Using the rules of exponents

a^{m} × a^{n} ⇔ a^{(m+n)}

(a^{m}) ^{n} = a^{mn}

Given

(y^{20} ) ((y^{-5}) ^{2}

= y^{20} × y^{-10}

= y^{(20-10)}

= y^{10} → in the form y^{n} with n = 10
