I am unable to solve this problem.
The answer is negative 149
-2y-6-7y
-9y-6
I hope that this helps!
I think you can find it graphically by points through a table you create like:
let x = 0, and find the value of y
for example for the first equation when we let x = 0 you find y = 6 and be in the form of (0,6) then draw them or you can let x = -2 or -3 , etc as you like
to be more accurate you can find 3 pionts and start graphing them
these two equations are straight lines and they will intersect in a point
Hello!
You divide the total time by the time unit for the slope
54 / 3 = 18
Multiply this by how height the cart goes
4 * 18 = 72
The answer is 72
Hope this helps!
