Answer:X = 3
Step-by-step explanation:
Answer:2000 for the first one 200 for the second
Step-by-step explanation:
<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.

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
