1)
x^2 + (3y/2z) = 7
2x^2z + 3y = 14z
3y = 14z - 2x^2z
3y = 2z(7 - x^2)
y = 2/3(z)(7 - x^2)
2)
(3zx^4) /(5+z) = 2y
3zx^4 = 2y(5+z)
3zx^4 = 10y + 2yz
Answer:
-2
Step-by-step explanation:
9+n/4= -15
cross multiply
9+4-15=n
13-15=n
n=-2
Answer:
x < ( 8 - 2b ) / -a
Step-by-step explanation:
For this problem, we simply will solve the inequality for x.
-ax + 2b > 8
-ax > 8 - 2b
x < ( 8 - 2b ) / -a
Note, the comparison is flipped since a negative multiplicand was used to isolate x.
Cheers.
Answer:
No, it is a parabola. (assuming that you meant to write 6x² - 2y = 7).
Step-by-step explanation:
If there is a square in the x or y, this gives it away that it cannot be a straight line.
