Answer:
- f(4) = -12
- f(-2) = -6
- f(2) = -10
- f(0) = -8
- f(-3) = -5
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
Personally, I find it easier not to deal with so many minus signs. I would rewrite the function to ...
f(x) = -(8 +x)
I find it easier to evaluate the series of argument values when they are in increasing order. This serves as a check, because we expect the function values to be in decreasing order.
f({-3, -2, 0, 2, 4}) = -(8 +{-3, -2, 0, 2, 4}) = -{5, 6, 8, 10, 12} = {-5, -6, -8, -10, -12}
- f(4) = -12
- f(-2) = -6
- f(2) = -10
- f(0) = -8
- f(-3) = -5

As always, for repetitive evaluation of the same function, a spreadsheet or graphing calculator is a handy tool.
21499 +12*x=22.75*x
21499=22.75x-12x
21499=10.75x
x=21499/10.75≈1999.9≈2000 books
Answer:
Step-by-step explanation:
Angles 1 and 5 are in corresponding positions, so since A and B are parallel to each other, angles 1 and 5 are also congruent. If they are congruent, then that have the exact same measure. That means that if the sum of them is 100, each one has a measure of 50 degrees.
Angle 4 is vertical to angle 1, so that means that angles 1 and 4 are congruent. If angle 1 measures 50, then so does angle 4.
Answer:
30 minutes
Step-by-step explanation:
We use the red line to determine the values
X = 360
Go up to the red line and go to the left
y = 30
