Use substitution to solve the system<br><br> 2y - 8 = x<br><br> 2x + 3y = -2

devlian [24]

Answer:

x=2y-8

We use the substitution of x in the second equation

2*(2y-8)+3y= -2

4y-16+3y=-2

7y-16= -2

7y= -2 +16

7y=14

y=14Ș7

y=2

so x= 2*2 -8

x=4-8

x=-4

the solution is (x,y)=(-4, 2)

What is the length of the line segment with endpoints (11,−4) and (−12,−4) ?

bija089 [108]

Answer:

Length of the line segment with endpoints (11,−4) and (−12,−4) is 23 units

Step-by-step explanation:

Given:

Endpoints are (11,−4) and (−12,−4)

To Find:

The length of the line = ?

Solution:

The length of the line can be found by using the distance formula

$\sqrt{(x_2-x_1)^2 +(y_2 - y_1)^2$

Here

$x_1$ = 11

$x_2$ = -12

$y_1$ = -4

$y_2$ = -4

Substituting the values

Length of the line

=> $\sqrt{((-12)- 11)^2 +((-4) - (-4))^2$

=> $\sqrt{(-12- 11)^2 +(-4+4)^2$

=> $\sqrt{(-23)^2 +(0)^2$

=> $\sqrt{529}$
