Answer:
$175
Step-by-step explanation:
let the original price be x
if 1/5 is off the price then the sells is at 4/5
4/5 of x = 140
thus,
4/5* x=140
4x = 140*5
x=700/4
x=$175
Answer:
9 x 5 - 9 = 36
Step-by-step explanation:
If you graph 4 separate triangles with the four different points, (2,3) and (1,5) form a right triangle.
Answer:
Its 5
Step-by-step explanation:
-3 * 5 = -15 , i.e smaller than 15.
The slope f'(x) = [f(4) - f(2)]/(4-2)≥3,
so [f(4) - 13]/2 ≥3
f(4) -13 ≥ 6
f(4)≥19, so it can be as small as 19.
