Melanie has 137 dollars in total.
Let each book cost=x
No of books=17
So total cost of 17 books=17x
After buying books Melanie left with 11 dollars
According to question the required equation will be=
17x+11=137
17x=137-11=126
x=8
i.e Price of each book is 8 dollars. (Answer)

Answer:
Step-by-step explanation:
Here,
y
∝
x
⇒
y
=
k
x
where k is constant.
⇒
1
=
k
.2
[put y =1,x=2]
⇒
k
=
1
2
Again, y = kx
⇒
y
=
1
2
×
4
[put x = 4]
⇒
Y
=
2
Answer:
y
=
2
Answer:
y - 2 = 6 (x - 1)
Step-by-step explanation:
Slope intercept form equations look like this:
y - y1 = m (x - x1)
***m = 
Using the point (1,2), we know that x1 = 1 and y1 = 2. Let's sub these values into the slope intercept equation:
y - 2 = m (x - 1)
To complete this equation, we need to find slope. Pick out another point on the graph and plug into the slope equation. We can use point (2,8), where (1,2) = Point 1 and (2,8) = Point 2.

Now that we know m = 6, let's plug that back into the original equation to get our final answer:
<u>y - 2 = 6 (x - 1) </u>
I hope this helps!
First, square both sides of equation so it ends up to be:
a/6=81
so
a=27/2
