|10x + 15| \geq 105\\
 5|2x + 3| \geq 105\\
|2x+3|\geq21\\
2x+3\geq21 \vee 2x+3\leq-21\\
2x\geq 18\vee2x\leq-24\\
x\geq9 \vee x\leq-12\\

Simplify the following.
GalinKa [24]

Answer:

(2f-17h)/24k

Step-by-step explanation:

We can make the common denominator for 3k and 8k in the form of 24k, so we get (multiply the first fraction by 8 and the second one by 3 to get 24k on each denominator) (8f-32h)/3k-(6f-15h)/24k. Now we can just subtract the numerators :

8f-32h-6f+15h (sign gets flipped on 6f and 15h), so we get

(2f-17h)/24k

Find the slope rise/run
Sloan [31]

Answer:

m = -1/3

Step-by-step explanation:

Find two points in order to calculate slope:

  • (0, 2)
  • (3, 1)

Slope (m) =

ΔY /ΔX= -1/ 3= -0.33333333333333

  • ( ΔX = 3 – 0 = 3
  • ΔY = 1 – 2 = -1 )

Slope intercept:

y = -0.33333333333333x + 2
