Pre Calc Question for one of my classes

Mathematics
1 answer:
Tatiana [17]3 years ago
5 0

Answer:

Step-by-step explanation:

f(x) is like y in a linear equation. There is one major difference. F(x) tells you what to substitute on the right every time you see an x.

f(a) = -3a + 7

f(b) = -3b + 7

For this question a and b have values. Now work with the right side only. This is the quickest way to get the answer, but it is only marginally correct.

f(a) = -3(-8) + 7 = 24 + 7 = 31

f(b) = -3(7) + 7 = -21 + 7 = - 14

f(a) + f(b) = 31 - 14 = 17

f(a) - f(b) = 31 - (-14) = 31 + 14 = 45

Answer: about 78 mL

Step-by-step explanation:

When you see the liquid in a curved shape, you want to look at the very bottom of the curve. The bottom shows that our answer will be in the 70 mL, but close to 80. If you look at the lines in between, we can see that there are 5 lines, meaning each line represents 2 mL. Now, we count up and reach 78 mL.

Answer:

Angle 1 - 51

Angle 2 - 39

Angle 3 - 90

Angle 4 - 51

Angle 5 - 17

Angle 6 - 129

Step-by-step explanation:

Angle 1 = 180 - 90 - 39 = 51

Angle 2 = 90 - Angle 2 (51) = 39

Angle 3 = 90

Angle 4 = 180 - Angle 2 (39) - Angle 3 (90) = 51

Angle 5 = 180- 90 - 34 -39 = 17

Angle 6 = 180 - Angle 4 (51) = 129
