When y is equal to 0, you get the x-intercept.

Replace y with 0 and solve for x.

0 = 4x + 16
-4x = 16 <--- Transpose the 4x to the left-hand side
x = -4 <--- Divide both sides by -4

So, the x-intercept is -4.

Answer:

(7,9)

Step-by-step explanation:

7x - 8y = -23

7x - 7y = -14

Solve the equation for 7x

7x - 8y = -23

7x = -14 + 7y

Substitute the given value of 7x into the equation 7x - 8y = -23

-14 + 7y - 8y = -23

solve the equation for y

y = 9

substitute the given value of y into the equation 7x = -14 + 7y

7x = -14 + 7(9)

solve the equation for x

x = 7

A math book at the victor valley college bookstore originally cost $84 to purchase if they sell it for $126 what is the markup r

Sergio039 [100]

50% because you first subtract the original price from the new price so 126-84 equals 42 then you divide that by the original price 84 which will give you .5 which turns to 50%
