Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
x = the number of weeks she mows the lawn
y = the amount of money in Jana's savings account
y = 25x + 125
[amount of money in savings account(y) = $125 plus $25 per week(x)]
y-intercept = 125
So if x = 0 weeks and y = $125 in the savings account, $125 was already/initially in the savings account before she started earning and depositing $25 per week. Your answer is C
Answer:
48 square feet
Step-by-step explanation:
First, make an equation for the perimeter. W is the width and since the length is three times the width it is 3W. W+3W+W+3W=32. Add like terms and you get 8W=32. 32 divided by 8 is 4 so the width is four. 4x3 is 12 so the length is 12. you get area by multiply length and width so 12x4 is 48.
Answer:
0.43y + 8.1
Step-by-step explanation:
