Answer:
x = -5 y = -9
Step-by-step explanation:
y = x -4
5x + y = - 34
substitute x-4 in for y to solve for x
5x + x - 4 = 34
solve for x . . . add 5x + x = 6x
so you now have 6x-4 = -34
add 4 to both sides of the equation
6x-4 + 4 = -34+ 4
6x = -30
divide both sides by 6
6x/6 = -30/6
x= -5
then you plug -5 for x in the first equation
y = x - 4
y= -5 -4
y =-9
x= -5 y= -9
You will multiply and combine similar variables using the rules of exports making the answer D: x^6
Answer:
It should be -2x +6
Step-by-step explanation:
13 min -> 39 min (to download)
2.5 * 60 -> x
x = 2.5 * 60 * 39/13 = 450 min
This assumes, uniforms non flickering download speed, with no cutoffs.
