James buys a shirt and a pair of socks on sale for 25% off.

bixtya [17]

Answer:

$12

Step-by-step explanation:

24 x 0.25 = 6 ----- The 6 represents how much money is being taken off the original price

24 - 6 = 18 ---- the price of the shirt after sale was $18

24 - 18 = 6 ---- after the sale the socks were $6

6 + 6 = 12 ---- the original price of the socks

What is the slope of the line represented by the equation y = 4/5 x -3? A-1 B-4/5 C4/5 D3

Cerrena [4.2K]

Option C

ANSWER:

For the given equation slope is $\frac{4}{5}$ so the correct option is c.

SOLUTION:

Given, line equation is $y=\frac{4}{5} x-3$

We need to find the slope of the given equation.

Above given equation is in the form of slope intercept form, i.e. y = mx + c

Where m is the slope and c is the intercept made on axis by this line.

By comparing the given equation and the general form, we can conclude that, m = $\frac{4}{5}$ and c = -3

hence, for the given equation slope is $\frac{4}{5}$ . so the correct option is c.
