Answer:
Eliminating
Step-by-step explanation:
The given equations are ,
- x+y=0
- x-y= -16
Here I would prefer to use Elimination Method. Since there is negative y and positive y in the equations . So we can eliminate y easily and then we can find x. Also , let's solve ,
<u>On </u><u>addition </u><u>:</u><u>-</u><u> </u>
→ 2x = -16
→ x = -16/2
→ x = -8
<h3>Hence the most preferred method is " Elimination Method ".</h3>
Answer:
your answer is right -2/3
Step-by-step explanation:
![m = \frac{y2 - y1}{x2 - x1} = \frac{10 - 4}{ - 6 - 3} = \frac{6}{ - 9} = - \frac{2}{3}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20%20%3D%20%20%5Cfrac%7B10%20-%204%7D%7B%20-%206%20-%203%7D%20%20%3D%20%20%5Cfrac%7B6%7D%7B%20-%209%7D%20%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B3%7D%20)
Answer:
m= 3/7
Step-by-step explanation:
I'm assuming the question is solve for the variable, m.
First step is to isolate the variable
In other words, let's move everything (but m) from the left side to the right side
To move 7 to the right side, we can either divide both sides by 7 or multiply both sides by 1/7 (both equal the same thing)
7/3m × 1/7 = 1 × 1/7
1/3m = 1/7
Now we must move 1/3 from the left to the right side
We can use the reciprocal, 3/1, to do this
1/3m × 3/1 = 1/7 × 3/1
m = 3/7
(a + b) (a-b ) - 4b - 4
<u>Explanation:</u>
Given:
a² - b² - 4b - 4
(a + b) (a-b ) - 4b - 4
This equation cannot be solved further.
Thus, the equation is (a + b) (a-b ) - 4b - 4
