How do you decide which variable to isolate in order to use the substitution method to solve a system of linear equation?​

It doesn’t really matter which variable you isolate first but usually you would use the one that’s by itself already. like for example one of the equations was y = 8. you would already have your y solve for so you would just have to plug that in for y in the other equation. personally, i usually do x first unless one of the equations has either x or y by itself already. i think its easier to just do x first and then solve for y after that, but it just depends on what the equations are; sometimes it might be easier to just do y first. hope this helps!

Simple...

as far as I can see it looks like you need two names for the angle formed..-->>

the angle would be acute

and

complementary

Meaning both those angles <DHR and <DHM  have to be both smaller than 90° but when you add them both they should equal 90°.

Thus, your answer.

Concider the functions: f(x)= (2/3)x and g(x)=(2/3)x-3+2. Which statement is true regarding the vertical and horizontal translat
ioda

The function g(x) is a translation to the right of 3 units and up 2 units of f(x), so the correct option is B.

<h3>Which statement is true regarding the vertical and horizontal translations from f(x) to g(x)?</h3>

For a given function f(x), we can write a vertical translation of n units as:

g(x) = f(x) + n

  • If n < 0, the translation is downwards.
  • if n > 0, the translation is upwards.

And a horizontal translation of n units as:

g(x) = f(x + n).

  • if n > 0, the translation is to the left.
  • if n < 0, the translation is to the right.

Here we have:

f(x) = (2/3)*x

g(x) = (2/3)*(x - 3) + 2

By comparing it with the general translations, we conclude that we have a traslation of 3 units to the right and 2 units up.

So the correct option is B.

Answer:

2) y = x - 4

   y = -x + 2

   => x - 4 = -x + 2

   => 2x = -6

   => x = -3

   => y = -3 - 4 = -7

3) y = 3x + 1

   y = 5x - 3

   => 3x + 1 = 5x - 3

   => 2x = 4

   => x = 2

   => y = 3(2) + 1 = 7

4) 2x + y = 8 => y = -2x + 8

   y = x - 7

   => -2x + 8 = x - 7

   => 3x = 15

   => x = 5

   => y = 5 - 7 = -2
