Answer:

y=-x/3+2

Step-by-step explanation:

If you graph out 3x-y-7=0, you will get a line that goes through the points (0, -7), and about (2.3, 0). If you graph out y=x/3+2, you have to make sure that this line forms a 90 degree angle on the previous line, thus making this line perpendicular to the previous line.

If p(x) = x²+x+6 and q (x)=3x-1 find q ( 1/4)
erma4kov [3.2K]
<h3>Answer is    -1/4</h3>

Work Shown:

q(x) = 3x - 1

q(1/4) = 3(1/4) - 1 ... replace x with 1/4

q(1/4) = 3/4 - 1

q(1/4) = 3/4 - 4/4 ... rewrite 1 as 4/4

q(1/4) = (3-4)/4

q(1/4) = -1/4

The p(x) function is never used.

Solve the rational equation 5/x = 4x+1/x^2
Irina18 [472]

Answer:

x = 1

Step-by-step explanation:

Set up the rational expression with the same denominator over the entire equation.

Since the expression on each side of the equation has the same denominator, the numerators must be equal

5x =4x+1

Move all terms containing x to the left side of the equation.

Hope this can help you
