Answer:
Your final answer is either
x≥-2 if your initial inequality was
6x+2≤2(5-x)
OR
x≤-2
if your initial inequality was
6x+2≥2(x-2)
Step-by-step explanation:
As shown you have an equality, not an inequality.
-6x+2=2(5-x) distribute through parenthesis
-6x+2=2(5)+2(-x)
-6x+2=10-2x add 2x to both sides
2x-6x+2=10-2x+2x
-4x+2=10 subtract 2 from both sides
-4x+2-2=10-2
-4x=8 divide both sides by -4
-4x/(-4) = 8/(-4)
x = -2
With the ≥ or ≤ sign you would solve the exact same way
except for the point where when dividing both sides by
-4 requires you to reverse the inequality.
Your final answer is either
x≥-2 if your initial inequality was
6x+2≤2(5-x)
OR
x≤-2
if your initial inequality was
6x+2≥2(x-2)
Answer:
z = 1 i hope this helps! :)
Step-by-step explanation:
given 12 = 15(z - 1/5)
distribute the 15 to both the z and the - 1/5
12 = 15z - 3
add 3 to both sides
15 = 15z
divide both sides by 15
1 = z
flip the equation around so the variable is on the left
z = 1
Answer:
g=22.5
Step-by-step explanation:
To solve, cross multiply
16/9=40/g
16*g=40*9
16g=360
Divide both sides by 16
16g/16=360/16
The 16s on the left will cancel, leaving us with
g=22.5
So, g=22.5, and the correct choice is the last one
Answer:
C
Step-by-step explanation:
The y intercept is is -3 so that eliminates 2 options. Next the king goes up to the top right so it’s a positive slope. So that leaves only one option. The slope goes up one and to the side two. So it’s 1/2
