Answer:
10.4 miles
Step-by-step explanation:
Write an equation for the total cost paid as a function of the # of miles driven:
L(x) = $6.75 + ($3.20/mile)x
and set this equal to $40.03 to determine the # of miles Lupita rode:
L(x) = $6.75 + ($3.20/mile)x = $40.03
Isolate the x term by subtracting $6.75 from both sides:
($3.20/mile)x = $40.03 - $6.75 = $33.28
Finally, divide both sides by ($3.20/mile):
x = $33.28 / ($3.20/mile)
= 10.4 miles
Lupita rode 10.4 miles in the taxi.

x=1/3
Step-by-step explanation:
Answer:
180 houses
Step-by-step explanation:
The 3 part of the ratio 10 : 3 represents 30 bungalows, thus
30 ÷ 3 = 10 ← value of 1 part of the ratio
10 parts = 10 × 10 = 100 ← number of flats
The 5 part of the ratio 9 : 5 represents 100 flats, thus
100 ÷ 5 = 20 ← value of 1 part of the ratio, then
9 parts = 9 × 20 = 180 ← number of houses
Answer:
The answer to your question is: y = -1/2 x + 1
Step-by-step explanation:
Data
A (-4 , 3)
B (6, -2)
Formula
(y - y1) = m(x - x1)
Process
(y - 3) = -1/2 (x + 4)
2(y - 3) = -1(x + 4)
2y - 6 = -x - 4
2y = - x - 4 + 6
2y = - x +2
y = -1/2 x + 1
