 { x + 2y = 4    * ( 3 )
  -3 x + 2y = -4 

 3 x + 6 y = 12
-3 x + 2 y = -4
---------------------
          8 y = 8
      
             y = 8 / 8
           
             y = 1

For x :

x + 2 y = 4

x + 2*(1 ) = 4
 
x + 2 = 4

x = 4 - 2

x = 2

Answer C   ( 2 , 1 )

hope this helps!

Given the point (10, 25) and m = 2.5 , write the equation for the function m(t) point-stope form.
dalvyx [7]

Answer:

the equation for the function m(t) point-stope form will be:

  • y - 25 = 2.5 (x - 10)

Hence, option D is correct.

The graph is attached below.

Step-by-step explanation:

Given

Point (10, 25)

Slope m = 2.5

To determine

Write the equation for the function m(t) point-stope form.

We know that the point-slope form of the line equation is

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

In our case:

  • m = 2.5
  • (x₁, y₁) = (10, 25)

so

substituting the values m = 2.5 and the point (10, 25) in the equation

y-y_1=m\left(x-x_1\right)

y - 25 = 2.5 (x - 10)

Therefore, the equation for the function m(t) point-stope form will be:

  • y - 25 = 2.5 (x - 10)

Hence, option D is correct.

The graph is attached below.
