Percent change formula states that
((New-old)/old) x 100 = the percent change / percent increase
So if we take your equation and plug it into our formula
((225-120)/120) x 100
(105)/120 x 100
.875 x 100
87.5 % increase of students on the trip
Hope this helps!
Answer:
-2
Step-by-step explanation:
Equate the expressions for y. This gives ...
... x - 1 = 2x + 1
Add -1-x to get ...
... -2 = x . . . . your value of x
Answer:
We can tell by the graph that it has a positive slope. The
y-intercept is at positive 4. Trying to find the next whole number intercept point will be at (-2,0). Count up and over from that point to the y-intercept point, and put it in rise over run form... 5/2 (up 5, over 2). Now apply these known variables into the slope intercept form: y = mx + b.
The final answer is: y = (5/2)x + 5
M is the slope and B is the y-intercept.
