Answer:
Step-by-step explanation:
I think you meant y = -x^n, where ^ denotes exponentiation.
If n is odd, the graph begins in Quadrant II and decreases through the origin into Quadrant IV. This is true of -x, -x^3, -x^5, and so on.
Step-by-step explanation:
If x is the volume of the first tank, and y is the volume of the second tank, then:
x + y = 55
x = 2y + 4
Solve the system of equations using either substitution or elimination. Using substitution:
2y + 4 + y = 55
3y + 4 = 55
3y = 51
y = 17
Solve for x using either equation.
x + 17 = 55
x = 38
The first tank holds 38 gallons, and the second tank holds 17 gallons.
