I need help figuring out what: f(r-2)=6x+7 is

Mathematics

Andrej [43]3 years ago

Answer:

f(r-2) = 6r -5

Step-by-step explanation:

f(r-2) is another notation for x = r-2

so we’ll plug in r-2 for x and solve:

f(r-2) = 6(r-2)+7

f(r-2) = 6r -12 +7

f(r-2) = 6r -5

17. 7 1⁄5 – 6 2⁄5 = ? A. 4⁄5 B. 13 3⁄5 C. 1 4⁄5 D. 1 1⁄5
Kay [80]
The answer is 4/5, A. First, we should convert everything into an improper fraction. This gives us 36/5 - 32/5. Next, we have to subtract and get an answer of 4/5. Usually, we would have to convert this number back into a mixed number, but 4/5 is less than 1 and is therefore the answer.

Hope this helps!

Kate scored 85,78,72, and 81 on 4 math tests. What score does she need on the fifth test to have at least an 80 average?
Elan Coil [88]

I am not good in this kind of question so maybe 84?

suppose the full marks for each of them is 100 so for 5 of them it will be 500 cause if you if you multiply 100 full marks by 5 it will be 500

so the answer to this question is maybe 84?

cause if you add all of them with 84 the outcome will be 400 and if you divide the 400 by 5 it will be 80
