Answer:

Step-by-step explanation:
When a quantity "A" varies DIRECTLY with another quantity "B", we can write the proportionality equation as:
A = kB
Where k is the proportionality constant (to be found)
In this problem, it is given x varies DIRECTLY with y, so we can write:
x = ky
Also, given, x = 11, y = -3, so we plug these into the equation and first find k:
x = ky
11 = k(-3)
k = -11/3
Now, we need to find x when y = 8, so we substitute and find x:

Answer:
1
Step-by-step explanation:
If you convert it to a decimal both fractions equal to 1.5/1.5 which makes the answer 1
Answer:
Step-by-step explanation:
f(x) = x^2 - 2x + 6
to find f(-1), we sub in -1 for every x
f(-1) = (-1^2) - 2(-1) + 6
f(-1) = 1 + 2 + 6
f(-1) = 9 <=======
