1st problem-no
2nd problem-yes
3rd problem-yes
4th problem-no
Consider the example
(3x+5) - (x-10)
When we subtract off the (x-10), we are basically subtracting off x and also subtracting off -10. This is the same as adding on 10 because -(-10) = 10
So we would have these steps
(3x+5)-(x-10)
3x+5-x+10
2x+15
Often students forget to distribute the negative all the way through and would have 3x+5-x-10 as an incorrect step. You need to multiply that -1 through to each term, so that's why the distributive property is used.
You add them and then it would be 30.6898033492

Answer:
y = 2/3x
Step-by-step explanation:
Slope-intercept formula: y = mx + b
m = 2/3 because the slope is 2/3.
b = 0 because the y value of the origin is 0, as the point is at (0, 0).
That makes y = 2/3x + 0, but adding zero does nothing so you take it out to get y = 2/3x.
