Answer:
x= 42
Step-by-step explanation:
x/2+9=30
x+18=60
x=60-18
x= 42
$10.71

Step 1
you can easily solve this by using a rule of three.
Let
x represents the money Eileen will pay if her bag weighs 63 pounds
the proportion is the same
then

Step 2
solve for x

Answer:
y = x + 3
Step-by-step explanation:
Slope-intercept form is represented by the formula
. We can write an equation in point-slope form first, then convert it to that form.
1) First, find the slope of the line. Use the slope formula
and substitute the x and y values of the given points into it. Then, simplify to find the slope, or
:
Thus, the slope of the line must be 1.
2) Now, since we know a point the line intersects and its slope, use the point-slope formula
and substitute values for
,
, and
. From there, we can convert the equation into slope-intercept form.
Since
represents the slope, substitute 1 in its place. Since
and
represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:

The distance between these points are 6
