The slope of the line that passes through the point \left( 2 , 4 \right)(2,4) and \left( 3 , 8 \right)(3,8) is

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

4+3x is the answer

hope you got it
