Answer:
y≥ 23
Step-by-step explanation:
y/3 - 7 ≥ 2/3
Add 7 to each side
y/3 - 7+7 ≥ 2/3+7
y/3 ≥ 2/3+21/3
y/3 ≥ 23/3
Multiply each side by 3
y/3 *3 ≥ 23/3*3
y≥ 23
Answer:
D) 1/2
Step-by-step explanation:
4/5x-1/10=3/10
4/5x=3/10+1/10
4/5x=4/10
4/5x=2/5
x=2/5÷4/5
x=2/5*5/4
x=10/20
x=1/2
Answer:
Step-by-step explanation:
Slope is the difference in y over the difference in x, or 23--21 / -4-7 = 44/-11 = -4
using the first point we get
y--21=-4(x-7)
y+24 -4(x+ -7)
-7 goes in the? box
