Answer:6x -6
Step-by-step explanation:
4 times x and 4 x -2 4x -8
2 times x and 2 x 1 2x +2
5 ≤ 2x+1 ≤ 7
Do not write the line underneath the greater than sign, it was the only sign available
x = 2.5
Well it depends...... (.5= 1/2)
Answer: Choice A
m = undefined
point (-2,5)
==================================================
Explanation:
The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)
Another point on this line is (-2,5) since this also has x coordinate -2.
------------------
All vertical lines have undefined slope.
Let's pick two points such as (-2,0) and (-2,1) and find the slope through them
m = (y2-y1)/(x2-x1)
m = (1-0)/(-2-(-2))
m = (1-0)/(-2+2)
m = 1/0
m = undefined, since we cannot divide by zero.
