Question

1) One equation of a system of equations is 5x + 2y = 10. What is the second equation such that the system is independent?

Answer 1

1. is C.  2. is B. 3. I don't know so sorry

Answer 2

1) You are supposed to solve for y from the given equation also know as slope-intercept form ... which is y = mx + b 

5x + 2y = 10 

Start by subtracting 5x from both sides....

2y = - 5x + 10 

Divide both sides by 2 to get y by its self...

y = - 5/2 + 5  is the answer

2) A) y = |x + 6| + 1 

Because the graph moved 6 to the left and 1 up

3)  The graph of y=|x/2| was shifted 4 units up
   
From y=|x/2| to the graph of the equation y=|x/2| +4

The formula is  f(x) = a ( x - h ) + k 

    k represents y value .... In the coordinate plane y values go up and down..

    h represents x value .... In the coordinate plane x values go right and left 

For example .....   f(x) = a ( x - 5 ) + 4 

 Means that  the graph moved 5 to the right and 4 units up..
