Answer:
see attached for a graph
x = 0.5 when y = 1
Step-by-step explanation:
The graph has a y-intercept of -1, which is halfway between 0 and -2. It goes up 4 units (2 vertical grid spaces) for 1 unit to the right (1 horizontal grid space). It seems to cross y = 1 at about x = 1/2.
x = 1/2 when y = 1.
Answer:
15 feet
Step-by-step explanation:
if the dog run is a rectangles then the formula for the perimeter is 2h+2l
if we plug in the numbers we know we get this:
2h+2(5)=40
2h+10=40
2h=30
h=15
Answer:
70
Step-by-step explanation:
39+5=44
100-44=56

Answer:
$407.34
Step-by-step explanation:
1. Find the discount. This can be done by multiplying the original cost by the discount percentage.
678.90 x 40% = $271.56
2. Subtract the amount of the discount from the original price.
$678.90-$271.56 = $407.34
The new price is $407.34
