Answer:
Yes it is a proportional relationship
Step-by-step explanation:
That is because 20 and 10 are your original and 40 and 20 and 60 and 30 match with it.
Answer:
3n+10
Step-by-step explanation:
6(n+4)-4
PEMDAS
start with parenthesizes
6 x n = 6n
6 x 4 = 24
so we have
6n+24-4
subtract the 4
6n+20
simplify by dividing by common factor
6n/2 =3n
20/2 =10
3n+10
Answer:
1.) 1-b, 2-a, 3-d, 4-c
Step-by-step explanation:
You recognize that the point-slope form of the equation for a line with slope m and point (h, k) is ...
... y - k = m(x - h)
____
Match this form to the given equations to determine (h, k). Once you determine (h, k) from the equation, find that point in the list of points to get your match-up. (All the slopes are correct, so you don't need to do any more work than just described.)
_____
For problems 3.) and 4.), use the above form with the given point and slope.
Answer:
Step-by-step explanation:
n ≥ -2 + 9
n ≥ 7
