We want: P(x,y) => P'(-x,-y)
Check each one:
A)
P(5,5) => P'(5,-5) Wrong
B)
P(-4,5) => P'(4,5) Wrong
C)
P(-4,-1) => P'(2,4) Wrong
D)
P(1,-5) => P'(-1,5) Correct
The answer is D.
The answer is d because y intercept is -3
You can do Guess and Check(but the smart way). You first get 102 and 12. Then, you can minus 3 from each one of them, getting 99 and 9, also being 11 times the other, so then the answer would be 180 - 99 or 90 - 9, equaling 81
Y = -9x is proportional because its in the format y = kx
if you graph this equation youll see that it is a straight line that passes through the origin
i hope this helps!!
Answer:
Five hours at both ski resorts cost the same
Step-by-step explanation:
Let x = hours Let y = cost
Black Diamonds Ski Resort: 25 + 10x = y
Bunny Hill: 50 + 5x = y
Since the cost should be equal, we can substitute for these two equations.
25 + 10x = 50 + 5x
Solve for x:
x = 5
Check: Plug in for x
Black Diamonds Ski Resort: 25 + 10(5) = 25 + 50 = $75
Bunny Hill: 50 + 5(5) = 50 + 25 = $75
The cost is the same, so we know that five hours has the same cost at both ski resorts.
I hope this is correct! Please mark me as brainliest if this is correct :3
