Answer:
75%
Step-by-step explanation:
$39= x-(0.25x)= 0.75x
A 25% discount takes off 0.25 of the price.
x= original price
To find the original we use something like the above equation
6x-24
you have to multiple the 6 by the number in the parentheses
Answer: It is the top right one.
Step-by-step explanation: That one passes the vertical line test. A function can't have any points that have the same x-coordinate.
Slope=m=(2-5)/(8-2)=-3/6=-1/2
y=mx+b
y=-x/2+b, using (8,2) we have:
2=-8/2+b
2=-4+b
b=6
y=-x/2+6 or more neatly
y=(-x+12)/2
Answer:
x = -11
Step-by-step explanation:
-12 = x - 1
-12 + 1 = x
x = -11
