Answer: The equation that has the solution x = 5 is 32−4x=12

Step-by-step explanation:

Hi, to answer this question we have to solve each equation and the one that has the solution x=5 is the correct.

The equation that has the solution x = 5 is 32−4x=12.

To confirm the answer we have to solve the equation by isolating the variable x.

32−4x=12

-4x = 12 -32

-4x = -20

x = -20 / -4

x =5

Feel free to ask for more if it´s necessary or if you did not understand something.

It would be 32-4x=12
32-4(5)=12
32-20=12
12=12

which description best describes the solution to the following system of equations y= -2x +3 y= -x + 1
marin [14]
For this case we have the following system of equations:
 y = -2x +3

y = -x + 1
 Equating the values of y we have:
 -2x +3 = -x + 1

 From here, we can clear the value of x.
 We have then:
 -2x + x = 1 - 3

-x = -2

x = 2
 Then, we look for the value of y.
 For this, we substitute x in any of the equations:
 y = -x + 1

y = -2 + 1

y = -1
 Answer:
 
The ordered pair solution of the system of equations, is given by:
 
(x, y) = (2, -1)

which equation in point-slope form contains the point (-3, 5) and has slope -1 ANSWERS y + 3 = -1(x-5) y-3= -1(x+5) y+5=-1(-3) y
castortr0y [4]

Answer:

<h2>y - 5 = -1(x + 3)</h2>

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

We have m = -1 and the point (-3, 5). Substitute:

y-5=-1(x-(-3))\\\\y-5=-(x+3)
