Answer:
I prodict the answer is C
Answer:
true for all x
Step-by-step explanation:
3x - 4 ≤ 2
Add 4 to each side
3x - 4+4 ≤ 2+4
3x<6
Divide by 3
3x/3 <6/3
x<2
or
2x + 11 ≥ -1
Subtract 11 from each side
2x + 11-11 ≥ -1-11
2x≥ -12
Divide by 2
2x/2 ≥ -12/2
x ≥ -6
x<2 or x ≥ -6
true for all x
2+4+6+8 = "i=1" "n=4" Σ 2i
X = -9, y = -3.4
You can get this by adding through and getting the x's to cancel. Then use the y value to solve for the x.
The answer is D
To solve the inequality:
3-2x >= -17
-2x >= -20
x <= 10 when you divide by a negative, the inequality sign switches
Graph D covers all numbers less than or equal to 10
