Step-by-step explanation:
are you sure the fuel consumption is given by 6,8 km/l ?
normally it is given by l/100km.
but ok, let's assume this is correct.
it would mean the car can drive 6,8 km with every liter of fuel in the tank.
how many liters will the car need to go 450 km ?
well, as many liters as 6,8 fits into 450 :
450/6,8 = 66.17647059... liters
this is not a very fuel efficient car ...
You need to make the right side = 0
To do this you subtract 10 from both sides of the equation:-
x^2 + 6x + 9 - 10 = 10 - 10
x^2 + 6x - 1 = 0
Answer:
y intercept=15 and slope is 3
Step-by-step explanation:
Ok so for this one we know the y intercept is 15 because the y intercept is wherever x=0 and in the table when x=0 y=15
to find slope we use (y2-y1)/(x2-x1) which when we put points (0,15) and (1,18) in for would be:
(18-15)/(1-0)
