Answer:
9
Step-by-step explanation:
f(x) = -x^2
f(3) = -3^2
f(3) = 9
C1000÷ct=w
you pretty much ×1000 and then ÷t and c
To be able to compare 2 fraciton we have to make common denominator and then we can just compare numerators.

Now we can compare numerator from the first (9) and from the second fraction (8)
9>8, so the bigger is 9/10
5x+4y = 73
-4x + 4y = -8
5x + 4y -(-4x+4y) = 73 -(-8)
5x + 4y + 4x - 4y = 81
5x + 4x + 4y - 4y = 81
9x = 81
x = 81÷9
x = 9
Substitute x = 9 into any of the equations to find y.
5(9) + 4y = 73
45 + 4y = 73
4y = 73 - 45
4y = 28
y = 28÷4
y=7
Answers :
x = 9
y = 7
The ratio is 9/12 and you can write it as a proportion. so you multiply 9 by 100 then divide it by 12. answer is 75% chance
