3x=15-6y in slope intercept form
sdas [7]

Answer:  y= -1/2x + 5/2

Step-by-step explanation:

3x = 15 -6y

+6y       + 6y

3x +6y =15

-3x           -3x

6y= 15-3x   divide both sides by 6

y= 15/6 - 3/6x

in slope intercept form us y= -3/6x + 15/6  in simplest form is y= -1/2x + 5/2

What is the value of x will make the inequality true. 5x - 10 < 75?
Ipatiy [6.2K]

Answer:

x=16 or any value less than 16.

Step-by-step explanation:

16x5=80 and subtract 10 you get 70. X has to equal a value that makes the whole left side of the equation "smaller" than the irght side, and 16 or any value less than that would accomplsish this.
