25. Any anymore in an absolute value |x| means how far the number is from zero. It doesn’t matter whether it’s a negative or a positive. Usually, you should be able to just take out any negative sign you see. Ex; |3| = 3 |-3| = 3 |-55| = 55 and so on

The answer is 25.

Explanation: absolute value is always the opposite of the number inside the bars unless if the number is already positive, absolute value is always positive.

Solve the system of equations 4x - 2y =8 3x + 4y = 17

igor_vitrenko [27]

Answer:

Solution: x = 3, y = 2, or (3, 2)

Step-by-step explanation:

Given the systems of linear equations with two variables:

$\displaystyle\mathsf{\left \{{Equation\:1:\:4x - 2y =\:8} \atop {Equation\:2:\:3x + 4y = 17}} \right}$

The <u>process of elimination</u> will be used to solve for the solution to the given problem.

First, we must multiply Equation 1 by 2:

(2)[4x - 2y] = 8(2)

8x - 4y = 16

Add the revised Equation 1 (from the previous step) to Equation 2:

$\displaystyle\mathsf{\left \ {{\quad \:\:\:8x\:- 4y = 16} \atop + {\quad\underline {\:\:3x\:+ 4y = 17\:} \underline}} \right.}\\\displaystyle\mathsf{\qquad\:\:11x\qquad\:=33}$

Next, divide both sides by 11 to solve for x:

$\displaystyle\mathsf{\frac{11x}{11}\:=\:\frac{33}{11}}$

x = 3

Substitute the value of x = 3 into Equation 1 to solve for y:

4x - 2y = 8

4(3) - 2y = 8

12 - 2y = 8

Subtract 12 from both sides:

12 - 12 - 2y = 8 - 12

- 2y = -4

Divide both sides by -2 to solve for y:

$\displaystyle\mathsf{\frac{-2y}{-2}\:=\:\frac{-4}{-2} }$

y = 2

<h2><u>Double-check:</u></h2>

In order to verify whether we have the correct values for the solution, substitute x = 3, and y = 2 into both equations:

Equation 1: 4x - 2y = 8

4(3) - 2(2) = 8

12 - 4 = 8

8 = 8 (True statement).

Equation 2: 3x + 4y = 17

3(3) + 4(2) = 17

9 + 8 = 17

17 = 17 (True statement).

Therefore, the solution to the given system is x = 3, y = 2, or (3, 2).

Help lol

mr Goodwill [35]

Answer:

Step-by-step explanation:

slope = (y2 - y1) / (x2 - x1)

(3/2,-2).....x1 = 3/2 and y1 = -2

(-3,7/3)....x2 = -3 and y2 = 7/3

now we sub

slope = (7/3 - (-2) / (-3 - 3/2) = (7/3 + 2) / (-3 - 3/2) =

(7/3 + 6/3) / (-6/2 - 3/2) = (13/3) / (- 9/2) =

13/3 * -2/9 = - 26/27 <====
