Answer: -2 (sqrt:6)/5
Step-by-step explanation:
#12. When x = 4, y = 5(4) - 1 = 20 - 1 = 19
when x = 12, y = 5(12) - 1 = 60 - 1 = 59
when x = 0, y = 5(0) - 1 = 0 - 1 = -1
when x = 0.5, y = 5(0.5) - 1 = 2.5 - 1 = 1.5
Y2-y1/x2-x1 then plug in numbers so 6-2/10-1 which gives 4/9
| -24x + 120| > 48
-24x + 120 > 48
-24x > 48 - 120
-24x > - 72
x < -72/-24
x < 3
-24x + 120 < -48
-24x < -48 - 120
-24x < - 168
x > -168/-24
x > 7
solution is : x < 3 or x > 7...answer B
7x-4y= - 12 is the standard form
