Please answer this with the steps included please<br> y-10 = -5/4x + 30/4<br> for middle school
Phantasy [73]
<span>y-10 = -5/4x + 30/4 represents a linear function; we know that because both x and y have the power 1.

We could put this equation into one of several forms.

Suppose we wanted to put it into slope-intercept form.  Then </span><span>y-10 = -5/4x + 30/4 becomes y = 10 + 30/4 - (5/4)x, or y = 35/2 - (5/4)x.  Thus, this line has the slope -5/4 and the y-intercept (0, 35/2).

If this isn't quite what you wanted, then please share the instructions.

What is the x-coordinate of the point where the lines x=4y-8 and 1/2x+y=11 interscent? <br>x=?
BlackZzzverrR [31]

Answer:

x = 52

Step-by-step explanation:

To answer this question, we need to set up a system of linear equations:

x = 4y - 8

(1/2)x + y = 11          (Note:  Please use (  ) around fractions such as this 1/2, to                    

                                  eliminate possible ambiguity)

We want to find the x-coordinate, so should start by elilminating y from this system of equations.  

Do this by multiplying the 2nd equation by -4.  This results in

-2x - 4y = -44

Combine this result with x = 4y - 8:

  x = 4y - 8

-2x - 4y = -44

----------------------

-x          = -52   (Notice how the "y" terms cancel each other out.)

Dividing both sides by -1 produces the desired answer:  x = 52
