Answer:
Step-by-step explanation:
$2.50(f) + $4(n) = Total Cost
$2.50(9) + $4(9) = Total Cost
$22.50 + $36 = Total Cost
$58.50 = Total Cost
If she lost 1/3 of her bows and still had 42, that means she had 63 bows before school because 1/3 of 63 is 21 and 63-21=42. If she got 7 for her birthday then 63-7=56. She had 56 bows before her birthday
Answer:
y = 0.2x + 3.4
Step-by-step explanation:
Slope intercept form of line is
y = mx + c
where
m = slope
c is y intercept
given that slope is 0.2 thus, m = 0.2
now equation of line
y = 0.2x + c
now we substitute value of x and y ( (-2, 3) in this equation as given that the given point passes through the line
3 = 0.2*-2 + c
3 = -0.4 + c
c = 3+0.4 = 3.4
put c = 3.4 in equation
y = 0.2x + c
y = 0.2x + 3.4
Thus,
third option , y = 0.2x + 3.4 is the correct answer
