Answer:
We just need the equations to equal the same, which is y.
5+1.10x=y
3+1.50x=y
5+1.10x= 3+1.50x
Let's get x by itself by subtract 3 from both sides.
2+1.10x= 1.50x
Now subtract 1.10x from both sides.
2= 0.4x
Now divide each side by 0.4
5=X
So, at 5 games they're the same cost. Let's find the cost.
5+1.1(5)= 5+5.5=10.50
3+1.5(5)=3+7.5= 10.50
So, at 5 games, they are $10.50.
Hope this helps! :)
Answer:
E = 324
Step by step explanation:
y - 3x = 7
can be written as
y = 3x + 7
For every value of x there is a unique value of y. For example when x = 0 y = 3(0) + 7 = 7
Yes it is a function.
In particular it is a one-to-one function.
