Answer:
A.) y = 20x
B.) 21 minutes
Step-by-step explanation:
y = mx + b; y2 - y1/ x2 - x1 = m (slope)
A.) If a factory can build 20 cars per hour, the first point would be (1, 20). To find the slope (m), divide the y-axis by the x-axis: 20/1 = 20.
B.) Before we can do this problem, we must first convert the hours to minutes. 1 hour = 60 minutes. Then we divide the minutes by the number of cars. 60 ÷ 20 = 3. That means the factory builds 1 car every 3 minutes. Multiply the number of cars, 7, by the number of minutes it takes to make one car: 7 • 3 = 21.
Hope this helps,

Answer:
148.2
Step-by-step explanation:
LA= PH
P= 8.2+8.2+3.2+3.2=22.8 in
H= 6.5 in
PH= 22.8(6.5)= 148.2 in
B as -$39 as he owes his mom that, then +30 as he earned it and then since he lent his sister $21 that’s $21 less so -$39+$30-$21
