Margie can drive 160 miles on $20 of gas
Answer:
y = 46
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 23 when x = 8 , then
23 =
( multiply both sides by 8 )
184 = k
y =
← equation of variation
When x = 4 , then
y =
= 46
Answer:
90%
Step-by-step explanation:

Answer:
The first one and the last one. A and D.
Step-by-step explanation:
A linear equation is and equation where the line is going up on a graph. In order for that to happen, y must always be bigger than x. The first and last chart all the way to the right is the only one that has that trait. :)
