Answer:

B) $50

Step-by-step explanation:

If we know that $15 is 30% of the original price, we can set up an equation as follows:

0.3x = 15

x is representative of the original price, and 0.3 represents the 30% discount. Isolate x and solve to get 50.

Given the equation 5(-2x -10) = 25(x + 1), solve for the value of x that will make the equation true.

Answer:

Step-by-step explanation:

5(-2x -10) = 25(x + 1)

-10x - 50 = 25x + 25

by transposing

-10x - 25x = 25 + 50

-35x = 75

x = -75/35

or 2.142857..... in decimal

WHAT IS THE SLOPE OF THE LINE PASSING THROUGH THE POINTS (-2, -7) AND (3, 5)?????? PLZ ANSWER QUICKLY!!

jarptica [38.1K]

Answer:

The slope of the line with points A(-2, -7) and B(3,5) is m = (12/5).

Step-by-step explanation:

The two pints are given as A(-2, -7) and B(3,5)

Slope of a line with points (a,b) and (c,d) is given as

$m =( \frac{d -b}{c-a} )$

So, here the slope of line AB is

$m =( \frac{5 - (-7)}{3 - (-2)} ) = \frac{5+ 7}{3 +2} = \frac{12}{5}$

or, m = 12/5

Hence, the slope of the line with points A(-2, -7) and B(3,5) is (12/5).
