Answer from: lalalooowt

(–2.2, –3)

Step-by-step explanation:

y = – 3

y = x – 0.8

Substitute the value of y into the second equation

-3 = x-.8

Add .8 to each side

-3 +.8 = x-.8+.8

-2.2 = x

-3 =y

The solution for the system of equations is (–2.2, –3)

Step-by-step explanation:

The solution of the system of equations can be expressed with its components in x and y in the form (x,y) where x is the value of x and y is the value of y. The values of x and y can be found solving the system of equations given.

1. Write the system of equations and name each equation:

y=-3 (Eq.1)

y=x-0.8 (Eq.2)

2. Replacing Eq. 1 in Eq. 2 and solving for x, we have:

y=x-0.8

-3=x-0.8

-3+0.8=x

-2.2=x

3. Express the answer as the solution tho the system of equations:

(x,y)=(-2.2,-3)

Answer from: barattah
Given ---›

y = -3

&

y = x - 0.8

So,
=> x = y + 0.8

=> x = -3 + 0.8

=> x = -2.2

Therefore, the best approximation for the solution to this system of equations is = (–2.2, –3)

Answer from: Gimagg8195
Given:
y = -3
y = x - 0.8

y = y
-3 = x - 0.8
-3 + 0.8 = x
-2.2 = x

The best approximation for the solution to the given system of equations is: (-2.2, -3)
ansver
Answer from: dondre54
The answer is C (-2.2, -3). 

In order to find the ordered pair we must use what we know from the first equation in the second. We already know that y = -3, so that goes into the second equation. 

y = x - 0.8
-3 = x - 0.8 
-2.2 = x
