Answer: $157.50
Step-by-step explanation:
$5250÷100=$52.50
52.50×3=$157.50
Answer is 0
the slope formula is y2-y1 / x2-x1
plug in (1,5) and (2,5)
5-5 / 2-1
0/1 = 0
Answer:
19 hours
Step-by-step explanation:
Issac shovels driveways to earn money. He can shovel 14 driveways in 8 hours. Earns $25.00 for each driveway. Issac is saving up to buy a new computer that costs $831.25. How many hours does Issac need to work to earn enough money to purchase the computer?
Step 1 find the number of driveways to shovel
25x = $831.25
x = $831.25/25
= 33.25 driveways
Step 2
He can shovel
14 driveways = 8 hours
33.25 driveways = x
Cross Multiply
14x = 8 × 33.25
x = 8 × 33.25/14
x = 19 hours
Step-by-step explanation:
it is a line (as the variable x is only occurring with the exponent 1, this makes this a linear equation or simply a line).
all we need to do is find 2 points, mark them in the graph, and the draw a line through both points (and beyond these points).
the first point for me is always for x = 0.
f(0) = 4×0 - 4 = -4
so, the first point is (0, -4)
and for a second point let's pick e.g. x = 2
f(2) = 4×2 - 4 = 4
so, this second point is (2, 4).
