you have to think that the original price multiplied by 0.75 (also known as 75%) gave the result of what he saves i.e 84 $. So we put up an equation with the original price multiplied by 75% which equals the 84 $ he saved on buying that item on sale
Answer:
Step-by-step explanation:
point-slope formula is asked for [y-y1 = m(x-x1]
where the given point, P=(x1,y1) = (-4,6)
and the slope , m is given as 3/2
so plug those into the formula
y-6=3/2(x-(-4))
y-6=3/2(x+4)
voila .. you are done :)
Answer:
Solutions:-5,0,9,6
Not solutions: 12.5,10
Explanation:
The inequality that was given is:
20 > 5 + 3x
First, group similar terms;
20 - 5 < 3x
15 < 3x
x = 5
Thus, the solutions are:-3.5, 5, 4 3/4, -15
The not solutions are:-10 2/3, 129,
Hope this helps! :)
