Replace every x you see with 5 and do the math.

f(x) = 2x^2 + 2x - 3

f(5) = 2(5)^2 + 2(5) - 3

f(5) = 2(25) + 10 - 3

f(5) = 50 + 10 - 3

f(5) = 60 - 3

f(5) = 57

9) Which equation represents the line that passes through the point (3,4) and is parallel to the x-axis?
kobusy [5.1K]
Since the line is parallell to the x-axis we know the slope is zero: m=0

Using the point-slope formula we can substitute know values:
y=mx+b
4=0(3)+b
b=4
y=0x+4
y=4

You could also jsut do it by inspection: since it passes through (3,4) and is horizontal it must cross at (0,4) i.e. all y=4.

Marisa decided to raise the price of her earrings so that she will make a profit of $5.00 on each pair. She has
Varvara68 [4.7K]

Marisa, who raise the price of her earrings so that she will make a profit of $5.00 on each pair, expect to make a profit with her company.

<h3>What is the unit price?</h3>

The unit price is the amount of money required to buy one unit of a item or goods.

To find the unit price, divide the total cost of the goods to the total number of goods.

The cost of repair will now be $60. Thus, the total cost of 50 earrings is,

C=60\times50\\C=3000

Marisa decided to raise the price of her earrings so that she will make a profit of $5.00 on each pair. Thus, the new selling price of her earring is,

P=60+5\\P=65

The sale's price of 50 earrings is,

P=50\times65\\P=3250

She has also improved the quality control so that only 1 pair in 50 need to be returned for repair. Thus, the cost price of one earring has to be removed from the sales price of 50 earrings as,

P=3250-60\\P=3190

The profit made by her company on 50 earrings is

p=P-C\\p=3190-3000\\p=190

Thus, Marisa, who raise the price of her earrings so that she will make a profit of $5.00 on each pair, expect to make a profit with her company.
