Step-by-step explanation:</h2>
<h3>1. Write the expression.</h3>
<h3>2. Substitute y for x, and x for y.</h3>
<h3>3. Solve for y.</h3>
<h3>4. Express your result.</h3>
.
180 - 149 = 31
x/100 *149 = 31
1.49x = 31
x= 31/1.46 = 20.81 %
Answer:
y=2x-19
Step-by-step explanation:
I'm guessing you mean slope intercept form y=mx+b
If so, first you would have to find the slope of the line
To do that, use the formula y2-y1/x2-x1
Remember you can pick any coordinate pair for this
I will pick 1=y2 -5=y1 10=x2 and 7=x1
When I put that in the equation I get 1-(-5)/10-7
Overall I get 6/3, or 2
Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)
I will pick (10,1)
1=y and 10=x and 2=m
1=2(10)+b
this simplifies to 1=20+b
now subtract 20 from both sides and get -19 = b
Now you have your equation y=2x-19
In order to solve this we can first convert 3h 28m to 208 minutes.
This will make it so we can find how many minutes it took her to run per mile.
The way we do that is by dividing 208 by 26. This leaves us with 8 minutes per mile.
Hope this helped at least a bit!
