Put this equation into slope-
intercept form.
5x – 4y = 12

y = 5/4x - 3

Step-by-step explanation:

Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

First, isolate variable y on the left side of the equation.

- 4y = - 5x + 12

Now, divide both sides by - 4 to solve for y.

y = 5/4x - 3

Step-by-step explanation: In slope-intercept or y = mx + b form, the y is by itself on the left side of the equation.

So our first task in this problem is to get

y by itself on the left side of the equation.

First subtract 5x from both sides to get -4y = -5x + 12.

I put the x term first because that's how it is in y = mx + b form.

Now divide both sides by -4 to get y = 5/4x - 3.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
