Answer:

y = 40.96

Step-by-step explanation:

Given

4 = $\frac{y}{10.24}$ ( multiply both sides by 10.24 to clear the fraction )

4 × 10.24 = y , that is

y = 40.96

Answer: -6 = x

Step-by-step explanation: Start by distributing through the parentheses

on each side of the equation to get 5x - 40 = 7x - 28.

Now move your x's to the right and

numbers to the right and you get -12 = 2x.

Divide both sides by 2 and -6 = x

Helppppppppp mathhhhhhhhhhhh

Since this is an isosceles right triangle the sides have equal length. From the Pythagorean Theorem:

h^2=x^2+y^2, where h=hypotenuse, x and y are the side lengths.

Since x=y=s and we are told that h=22 we can say:

2s^2=22^2

2s^2=484

s^2=242

s=√242

s=√(121*2)

s=√(11*11*2)

s=11√2

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify points from graph.

Point (8, 5)

Point (4, 2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(8 - 4)^2 + (5 - 2)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{4^2 + 3^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{16 + 9}$
[√Radical] Add: $\displaystyle d = \sqrt{25}$
[√Radical] Evaluate: $\displaystyle d = 5$
