Answer:
-15x<=45 and 14x<=-42
x>=45/-15 and x<=-42/14
x>=-3 and x<=-3
so x=-3
Step-by-step explanation:
the answer of 0.4 is 2/5 or 2 1/5
Convert the given mileage of the automobile from miles per gallon to kilometers per liter through the given conversion factors.
(34 miles / gallon) x (1.61 km / 1 mile) x (1 gallon / 3.79 L) = 14.44 km/L
Thus, the automobile can travel about 14.44 kilometers per liter of the gasoline.
Y = mx + c
Where
y is the y of (2, -8)
x is the x of (2, -8)
m is the gradient or slope
c is the y intercept (you don’t know what it is)
Put into equation and find c
Once find c rewrite the equation with only the m and c in numbers
Eg
y = 5x + 3 (this is an example not the answer)
