Answer:
C
Step-by-step explanation:
A and B are not straight lines, so they are not linear functions.
C and D are straight lines, so they are linear. However, D fails the vertical line test, so it is not a function.
8/1 + (x-1)/(x+4)
You need the same common denominator (bottom number) to be able to add together so multiply 8 by (x+4) to both bottom and top
8 (x+4)/(x+4) + (x-1)/(x+4)
Add
8 (x+4)+(x-1)/ (x+4)
Distribute the 8 to (x+4)
8x+32+x-1 / x+4
Simplify
9x+31/x+4

Answer: The answer is 3.60 dollars.
Step-by-step explanation:
1 bottle = 10 cents
12 bottles = 120 cents
100 cents = 1 dollar
1 cent = 1/100
120 = 1/100 * 120 = 1.2 dollars
now
1 aluminium can = 5 cents
48 cans = 5*48 = 240 cents
240 cents = 1/100 * 240 = 2.4 dollars
so total = (1.2+2.4) dollars
= 3.6 dollars
He can eat 30 things of candy in 3 minutes so that is 10 pieces every minute. So that would be 10x, and he has already eaten 57 pieces. Your equation would be : c = 10x + 57
Oscar's budget is 2500. So if he is 500 under budget....2500 - 500 = 2000....so he spent 2000
=====================
f(x) = 38x + 10x - 3...when x = 2...so simply sub in 2 everywhere there is an x
f(2) = 38(2) + 10(2) - 3
f(2) = 76 + 20 - 3
f(2) = 93 <==
