No
in the first equation x is = to 10
in the second equation x is = to 9

I got this by first subtracting 7 from 27. I got 20. then I divided 20 by 2 and got 10 for x

for the second I subracted 1 from 28 and got 27. then I divided that by 3 to get x=9

First factor the numerator
b^2-6b+8/b-4 * b+8/b-2

u will get
(b-2)(b-4)/(b-4)*(b-2)*b+8
those will cancel out each other will left only
b+8

Create the equation of a line that is perpendicular to 2y=14+(2/3) x and passes through the point (-2,8).

Answer:

y = -3x +2

Step-by-step explanation:

If you divide the equation for the given line by 2, it will be in slope-intercept form:

y = (1/3)x +7

This tells you its slope is 1/3. The slope of the perpendicular line is the negative reciprocal of this: -1/(1/3) = -3. The point-slope form of the equation for the perpendicular line can be written as ...

y = m(x -h) +k . . . . . line with slope m through point (h, k)

Your line is ...

y = -3(x -(-2)) +8

y = -3x +2
