4 5 3 are the correct answers
Answer:
A.
Step-by-step explanation:
m = y2-y1/x2-x1
m = 12-4/15-5
m = 8/10
m = 4/5
Time = Distance / Speed
T = 8.5 miles/ 22 miles = 0.3863
Answer:
f(86)-f(82)
Step-by-step explanation:
well f of 82 = 2 plus _ plus _ plus _ and f of 86 is 2+_+_+_ subtract them
(A) 3 (B) 4 (C) 47 (D) 59 (E) 83
these are some possible answers so the answer is b, 4
btw, 86-82 = 4 duh
The first answer of part A is 32
So 4y means you have to multiply 4 by y, which is 20 since 4x5=20
And then you add 12, which is 32.
The second answer to part A is 40
With the second question of part a, the expression is basically saying 4 times whatever 5+3 is. So 5+3= 8, and 4(8) is 40
For part B, they are equivalent because let’s pretend y=2. 12+4y= 20. And then 4(y+3) would equal 20 because 4(2)=8 and 4(3)=12 and 8+12=20. This might not be the answer that your teacher is looking for, but it’s still a right answer so technically they can’t say it’s wrong unless you have a super unfair teacher
