Solve for each variable in the equation 5x+6y+7z=90 a. x
b. y
c. z
d. How are the results in parts (a)-(c) related?
Help! Due at 12:59.

Ok, so I think

X=(90-6y-7z)/5

Y=(90-5x-7z)/6

Z=(90-5x-6y)/7

I think they are related because all of the answers (a)-(c) have 90 subtracted by the following variables. Also all of the results include fractions... I don’t know for sure if this answer is right though, sorry

The graph of y = 4x - 3 is reflection of the graph of y = (-4x + 3) in the x axis

Step-by-step explanation:

We are told that y = -4x + 5.

This means that the graph of y = -4x + 5 - 2 = -4x + 3 shifts upwards by 2 units.

So the graph of y = -4x + 5 is the graph of y = -4x + 3 shifted upwards by 2 units.

Now, since it is reflected, it means that the graph of y = -(-4x + 3) = 4x - 3 is reflection of the graph of y = (-4x + 3) in the x axis

Therefore, the graph of y = 4x - 3 is reflection of the graph of y = (-4x + 3) in the x axis
