Answer:

<em>Solving the system of equations using elimination involves eliminating one variable by adding or subtracting the equations. Elimination method is as follows:</em>

5)2x + 6y = -12)

2(5x - 5y = 10

10x - 30y = -60

10x - 10y = 20

We subtract the equations eliminating the 10x term.

40y = -80

y = -2

x = (10 + (-2)5) / 5

x=0

Hope this helps!

Let 6x-3y=3 be equation 1 and -2x +6y=14 be equation 2.

Take 2 common from eq 2 let the optioned eq be equation number 3.

And solve eq number 1 and 3.

Algebra 3, in the excercise size the graphs to determine the functions domain and range, x and y intercepts if any, and the func
fredd [130]

Answer:

Read Explanation

Step-by-step explanation:

The domain is a list of all possible x-values, this graph starts at 0 and proceeds to positive infinity, making the domain:

[0,∞)

The range is a list of all possible y-values, this graph starts at -1 and proceeds to positive infinity, making the range:

[-1,∞)

x-intercepts Are where the line crosses the x-axis, in this graph the line only crosses the x-axis at x of 2. Making its only x-intercept 2.

y-intercepts Are where the line crosses the y-axis, in this graph the line only crosses the y-axis at y of -1. Therefore its y-intercept is -1.

In function notation when a question asks for f(x) its asking for the y values at the given x-values. At x of 3 the y value equals 1.

Please help ! Algebra
Simora [160]

Answer:

C

Step-by-step explanation:

y = (2x - 2) / 4 Interchange x and y

x = (2y - 2) / 4  Multiply both sides by 4

4x = 2y - 2       Add 2 to both sides.

4x + 2 = 2y       Divide both sides by 2

4x/2 + 2/2 = 2y / 2

2x + 1 = y

Now put 3 in wherever you see an x

2*3 + 1 = y

6 + 1 = y

7 = y
