Answer:
C. Reflection over x- axis, down 6 right 3
Step-by-step explanation:
Answer:
(X=Y)=(3,6)
Step-by-step explanation:
5x-4(4x-6)=-9
x=3
y=4x3-6
y=6
Step-by-step explanation:
This is most easily solved by writing the factored form:
Notice how, if we were to substitute -9 for x, the left part would be -9 + 9 = 0. Since (x + 1) × 0 = 0, this makes the function 0. The same logic applies for the right part.
Don't hold me accountable but I believe it is the 2nd equation.
Answer: B. He loses 1/5 of his points in the next crash
Plug in x = 0 to get y = 100(4/5)^0 = 100. He starts with 100 points
After x = 1 crash happens, he has y = 100(4/5)^1 = 80 points left. He lost 20/100 = 1/5 of his points after one crash.
