Answer:
b = $423.25
Step-by-step explanation:
cost of car rent per day = $25
Cost of GPS rent per day = $12.95
Cost of gas per gallon= $4.30
A car has 19 gallons and a GPS
The cost of gas for 19 gallons = 4.30 * 19
= $81.70
Total bill = b
Number of days = d
b = (25 + 12.95)d + 4.30*19
b = 37.95d + 81.70
When d = 9 days,
b = 37.95(9) + 81.70
b = 341.55 + 81.70
b = $423.25
Answer:
-2 because rise over run is -2/1 or -2
Step-by-step explanation:
Answer:
y = -3x
Step-by-step explanation:
(a) Slope
y = mx + b
Choose points (-3, 9) and (3, -9)
m = (-9 - 9)/(3 – (-3))
m = -18/(3 + 3)
m = -18/6
m = -3
=====
(b) y-intercept
y = mx +b
Choose point (0,0).
0 = 0 + b
b = 0
=====
(c) Equation of line
y = mx + b
y = -3x
If they get unexpected results they could note what they could've done wrong or what they could change in a next trail of experiments. Or look back and see what different happened to they could've hypothesized. There could be many different courses on what to do next.
