Answer:

y=-5/2x+4

Step-by-step explanation:

find the slope by using y2-y1/x2-x1

-1-19/2-(-4)

simplify

-20/8

simplify

-5/2

use slope-intercept form, y=mx+b

since we know the slope, find b

plug in one of the ordered pairs into the equation

-1=(-5/2)(2)+b

simplify

-1= -10/2+b

simplify

-1=-5+b

add 5 to both sides

b=4

plug b into y=-5/2x+b

y=-5/2x+4

Answer:

The length of the hypotenuse is 26 inches

Step-by-step explanation:

The leg(brace) attached to the wall is 10 inches

Perpendicular = 10 inches

Your surfboard sits on a leg that is 24 inches.

Base = 24 inches

Formula : $Hypotenuse^2 = Perpendicular^2 +Base^2$

$Hypotenuse^2 = 10^2+24^2$

$Hypotenuse = \sqrt{10^2+24^2}$

Hypotenuse = 26

Hence the length of the hypotenuse is 26 inches

the ratio of kiara money to tyler is 9:7. if kiara had $126 how much money do kiara and tyler have together

PolarNik [594]

To solve this problem, we can make a proportion.

Since Kiara's money has a ratio of 9:7 in comparison to Tyler's, we can make the proportion as follows:

9/7=126/x, where x is Tyler's money. This can be simplified to 9=882/x, or 9x=882. Then, divide by 9 to find x, which results in x=98.

Now we know that Tyler has $98, so we just need to add 126 to 98 and get $224 all together.

Hope this helps!
