Answer:
v=7
Step-by-step explanation:
i just used a math website for my answers and told it to simplify. try using that website. i always get an 90-100's on my tests from using that
-3x + 20 > = 8
-3x > = 8 - 20
-3x > = -12
x < = -12/-3
x < = 4
( - infinity, 4] <== interval notation
25% because I did 6.5 divided by 26
1/5x + 2/3(15) = 30
1/5x +10 = 30
1/5x = 20
x = 20 * 5
x = 100
C)2+(-3);-1
If you look at the model you see it meets at zero both ways go to -1 and 2 but when you travel to -1 its -3 because you move backwards on the model
