3 is the slope. method: y2-y1 over x2-x1
First do 43 - 30= $13 for two hats
so for one hat you do 13 divided by 2 which equals= <u>$6.50</u> for one hat
then you do 30 - 13= $17 for two pairs of gloves
so for one pair of gloves you do 17 divided by 2=<u> $8.50</u> for one pair of gloves
this is the quadratic formula
Hey there! I'm happy to help!
Here's how to find the distance between any two points.
Find the difference of the x values.
-5-7=-12
Square it.
-12²=144
Find the difference of the y values.
6-3=3
Square that.
3²=9
Add the two numbers we got.
144+9=153
√153≈ 12.37.
Have a wonderful day! :D
To simplify this, we need to distribute the coefficient:

The answer is C.
