Answer: 68
Step-by-step explanation:
Answer:
1. y = 2m + 4
2. y = 3m + 1
3. y = 2/3m +1
4. y = 4m -6
Will answer any questions in the comments
Step-by-step explanation:
1. 1 -> 5 = 4
6 -> 14 = 8
8/4 = 2
y = 2m + 4
2. 2 -> -3 = -5
-5 -> 10 = 15
5/15 = 3
y = 3m + 1
3. 9 -> -3 = -12
11 -> 3 = -8
-8/-12 = 2/3
y = 2/3m + 1
4. 3 -> -2 = -5
6 -> -14 = -20
-20/-5 = 4
y = 4m - 6
Answer:
r=0.2
Step-by-step explanation:
Given the quantities x and y
![\left|\begin{array}{c|c}x&y\\---&---\\8&1.6\\15&3\\2&4.4\end{array}\right|](https://tex.z-dn.net/?f=%5Cleft%7C%5Cbegin%7Barray%7D%7Bc%7Cc%7Dx%26y%5C%5C---%26---%5C%5C8%261.6%5C%5C15%263%5C%5C2%264.4%5Cend%7Barray%7D%5Cright%7C)
When x=8, y=1.6
On Substitution into y=rx
1.6=8r
r=1.6/8=0.2
When x=15, y=3
On Substitution into y=rx
3=15r
r=3/15=0.2
When x=2, y=0.4
On Substitution into y=rx
0.4=2r
r=0.4/2=0.2
Therefore, the constant of proportionality, r=0.2
NOTE: One set of values is enough to determine this. Others are done for verification.
Answer:
2 gallons of gas
Step-by-step explanation:
if there is 4 gallons for 80 and there would then be 40 which is half of 80 then there would be half as much of the gallon of gas
