You have to use the substitution method by substituting one Y value with the other
Answer:
C.
Step-by-step explanation:
When you write the equation of a line in slope-intercept form,
y = mx + b,
m is the slope.
Parallel lines have equal slopes.
The given line is
y = (4/5)x - 1
and has slope 4/5.
The only equation in the choices with slope 4/5 is in choice C whose line is
y = (4/5)x + 2.
1) (12p-3)(12p-3)
=144p^2-36p+36p+9
=144p^2+9 (-36+36=0 so it cancels out)
The regular price is 3.18.
50% off half the price, so you can either divide the regular price by 2 or multiply it by 0.50
3.18 / 2 = 1.59 ( 3.18 *0.50 = 1.59)
so the sale price is 1.59
now subtract the sale price from $5 to find the amount of change they got back:
5.00 - 1.59 = $3.14 change back
