Answer:

y = (5/2)x - 5

Step-by-step explanation:

5x-2y = 10

Subtract 5x from both sides

-2y = 10 - 5x

Rearrange

-2y = -5x + 10

divide both sides by -2 to isolate y

y = (5x/2) + (10/-2)

y = (5/2)x - 5

Answer:

y = 5/2x - 5

Step-by-step explanation:

Step 1: Write equation

5x - 2y = 10

Step 2: Solve for x

Subtract 5x on both sides: -2y = 10 - 5x
Divide both sides by -2: y = -5 + 5/2x
Rewrite: y = 5/2x - 5

Use the substitution method to solve the system of equations. choose the correct ordered pair. 2x - y = 103x - 2y = 8

crimeas [40]

$2x-y=10\Rightarrow 2x-10=y \\ 
\Longrightarrow 3x-2y=8\Rightarrow 3x-2(2x-10)=8 \\ 
3x-4x+20=8 \\ -x=8-20=-12 \\ x=12 \\ \\ y=2(12)-10=24-10 \\ y=14 \\ \\ (x,y)=(12,14)$

What is the distance to the earth’s horizon from point P? Express your answer as a decimal

rewona [7]

Answer:

The distance to the earth's horizon from point P is 216.2198187 mi, appriximately 216.22 mi

Step-by-step explanation:

This is a right triangle:

Hypotenuse: c=3959 mi + 5.9 mi → c=3964.9 mi

Leg 1: a=x=?

Leg 2: b=3959 mi

Using the Pytagorean theorem:

a^2+b^2=c^2

Replacing the known values:

(x)^2+(3959 mi)^2=(3964.9 mi)^2

Solving for x: Squaring:

x^2+15,673,681 mi^2=15,720,432.01 mi^2

Subtracting 15,673,681 mi^2 both sides of the equation:

x^2+15,673,681 mi^2-15,673,681 mi^2=15,720,432.01 mi^2-15,673,681 mi^2

x^2=46,751.01 mi^2

Square root both sides of the equation:

sqrt(x^2)=sqrt(46,751.01 mi^2)

x=216.2198187 mi

x=216.22 mi
