The question is asking for you to plug in each number in the brackets into x and solve for y, or f(x), g(x), etc. I will do no. 19 as an example:
f(x) = -3x + 1
This problem has the domains -2, -1, and 0. First, we'll start with -2:
f(x) = -3(-2) + 1
f(x) = 6 + 1
f(x) = 7
Now -1:
f(x) = -3(-1) + 1
f(x) = 3 + 1
f(x) = 4
Lastly, 0:
f(x) = -3(0) + 1
f(x) = 0 + 1
f(x) = 1
For question 23, we can use the distance formula, which is ratextime. The domain in this case is time (t). You can set up a function like this: d(t) = 60t
Answer:
Step-by-step explanation:
If it's (-216):
(-216) + 3(5 - 4 x 2)
(-216) + 3( -3)
(-216) -9
-225
If it's -2(16):
-2(16) + 3(5 - 4 x 2)
-2(16) + 3(-3)
-32 - 9
-41
Answer:
1/2
Step-by-step explanation:
2 1/4 - 1 3/4 Because the denominator are already the same, all you have to do is make it a mixed number and subtract. To do that you multiply the whole number to the denominator and add that new number to the numerator. So you would then have.
9/4 - 7/4
Keep the denumerator the same and subtract the numerators.
2/4
Then simplify
1/2
Answer:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate.
