-3y = x...so we sub in -3y for x in the other equation
-x + 7y = 70
-(-3y) + 7y = 70
3y + 7y = 70
10y = 70
y = 70/10
y = 7
so we sub in 7 for y in either of the original equations to find x
-3y = x
-3(7) = x
-21 = x
so ur solution is (-21,7)

Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Do you have any idea on how this is solved? When (h, k) both equal 0; you get a special formula. x^2 + y^2 = r^2 --- x^2 + y^2 = 25
And you can kinda look at the graph and guess which one it'll be.

Answer:
Cube the scale factor 0.25. Then multiply the volume of the box by 0.015625.
