(Distribute the 3)
6x +15 <span>≥ 2(x + 6)
(Distribute the 2)
6x + 15 </span><span>≥ 2x +12
(subtract 2x from both sides)
4x + 15 </span><span>≥ 12
(subtract 15 from both sides)
4x </span><span>≥ -3
(divide by 4x on both sides)
x </span>≥ -0.75
Hope that helped!
Answer:
D. Maya is incorrect because she listed the runners from least improved to most improved. Runners that decreased times are improving, and those that add time are not improving.
Step-by-step explanation:
I got it right on edge
I have it. Let me just type it in.
-(-7y + 12) = 7y - 12
u are distributing the -sign through the parenthesis...so u take the number outside of the parenthesis (and if it just a sign, the number is 1)...and u multiply it by everything in the parenthesis.
-1(-7y + 12) = -1 * -7y + (-1) * 12 = 7y + (-12) = 7y - 12
