Answer:
y = 2x - 2
Step-by-step explanation:
2 x + y = 2
2x - 2 = y
Answer:
Step-by-step explanation:
Ok so to find constant of proportionality, you need to find K.
X would be gallons and y is cost.
To find k you need to do k=y/x
k=17.50/5
k=3.5
That's the first one. Now you need to make sure its <em>constant</em> with each one so keep going.
k=35/10
k=3.5
k=52.50/15
k=3.5
For all of those 3.5 was constant.
Because they are constant, that means the data in the graph is a proportion.
An example of an unproportional relationship would be if instead of 15 in the last column, it was 16.
k=52.50/16
k=3.28
That be different from the other 3.5's meaning its not proportional. But that's just an example.
If you need extra help reach out to me and I'll help you best I can. I hope this helps though. <3
Answer:
312
To find the number that is 80% of 390, multiply 390 by 80%.
80% = 0.8.
390 * 0.8 = 312
(6,1) , (3,4)
slope = (4 - 1) / (3 - 6) = -3/3 = -1
y = mx + b
slope(m) = -1
use either of ur points....(6,1)...x = 6 and y = 1
now sub and find b, the y int
1 = -1(6) + b
1 = -6 + b
1 + 6 = b
7 = b
so ur equation is : y = -x + 7
