Answer:
x=3
y=5
Step-by-step explanation:
x+5y=28 (i)
-x-2y=-13. (ii)
add equation 2 from equation 1
x+5y=28
-x-2y=-13
3y=15
y=5
put the value of y in equation 1
x+5y=28
x+5*5=28
x+25=28
x=28-25
x=3
Answer:
x-axis only.
Step-by-step explanation:
2x = 5y2 - 3
Convert to vertex form:
x = 5/2 y^2 - 3/2
This is a parabola with axis of symmetry y = 0. The vertex is at (-3/2, 0) and it opens to the right.
The axis of symmetry is the x-axis ( y = 0).
