Hey, TailsIsTheBest!
Great question=)

Question:What is the value of the expression f2 + 8 if f = 7?

Answer:22

Work:They already gave us the value of the variable f, so all we have to do it plug in 7 for f's place.

(7)2+8
7*2=14
14+8=22

I hope this helps;)
If you have any questions on my work, feel free to ask me.

If the values are placed right next to each other without a symbol, then you multiply them.
So, you multiply the value of 7 with 2, since they are placed right next to each other.
(7x2) + 8 = 14 + 8 = 22

Change 5x - y = 3 into slope-intercept form. © by – 5x+3

agasfer [191]

The slope intercept form is $y=5x-3$

Explanation:

The equation is $5 x-y=3$

Now, we shall bring the equation $5 x-y=3$ in the slope intercept form.

The general form of the slope intercept is given by

$y=mx+c$

Hence, we need to rewrite the given equation in this form.

Thus, we have,

$5 x-y=3$

Subtracting both sides of the equation by 5x, we get,

$-y=-5x+3$

Multiplying both sides of the equation by (-), we get,

$y=5x-3$

Thus, the slope intercept form of the given equation is $y=5x-3$

A clothing store pays $89.47 for a dress. The store’s percent of markup is 50% and the tax is 7.6%. Find the selling price for t

Goryan [66]

Hi,
SP=Selling Price
CP of dress= $ 89.47
percent of mark up = 50%
SP without tax= 100+ mark up % /100 * CP
SP without tax= 100+50/100 * 89.47
SP without tax= 150/100 * 89.47
SP without tax= 1.5 * 89.47
SP without tax= $ 134.205
tot. SP(SP with tax)= 100 + tax %/100 * SP
SP=100 + 7.6/100 * 134.205
SP= 107.6/100 * 134.205
SP= 1.076 * 134.205
SP= $144.40458
Hope this helps you.
