It’s a because you have to calculate and do the formal slope
Answer:
a) 1/7 liters of petrol is used for each mile
Step-by-step explanation:
Justin fills his car with 40 litres of petrol. After travelling 35 miles it's down to 35 litres.
From the above statement:.
The difference is :
40 litres - 35 liters = 5 liters
Hence:
After travelling 35 miles he used 5 liters
(a) How much petrol does the car use each mile?
This is calculated as:
35 miles = 5 Liters
1 mile = x liters
Cross Multiply
35x = 5 Liters
x = 5/35
x = 1/7 liters
Hence, for each mile, 1/7 liters of petrol is used
B.) 91
13x7=91 being the lowest common multiple available
Answer:
y- (0,2.5) x-(3.5,0)
Step-by-step explanation:
This is because the intercepts of a graph are the points at which a line intersects with a desired axis. So for the Y axis the inercept would be at 2.5 making the y intercept (0,2.5). The same concept is used on the X axis.
