x = -7½
Now of course, you have to check the bottom equation:
4[-7½] + 10 = -20
-30 + 10 = -20 ✅

Answer:
Step-by-step explanation:
Are these polynomials ?
y = k / x² ( y varies inversely as the square of x )
y = 1/8 when x = 1:
1/8 = k / 1²
8 k = 1
k = 1/8
For x = 5:
y = 1/8 / 5² = 1/8 : 25 = 1/8 · 1/25 = 1/200
Answer: A ) 1/200
Hope This Helps!!!
Answer:
5x - 8y = -48
Step-by-step explanation:
Move 5/8x to the y side to get (-5/8)x + y = 6. Multiply both sides by -8 to get 5x - 8y = -48.
