Answer:
And solving we got:
If we subtract 100 from both sides we got:
Step-by-step explanation:
For this case we have the following equation given:
We want to find a general expression given by:
Where the center is (h.k) and the radius is r.
We can begin completing the squares of the equation given and we got:
And solving we got:
If we subtract 100 from both sides we got:
Then we can conclude that the center is:
And the radius would be:
500- 300 = 200
750 - 725 = 25
200÷ 25 = 8
it will take them 8 months for the total rent to cost the same
2x + 3y = 6
Put this into y=mx+b form (which is also called slope-intercept form)
Where m=slope and b=y-intercept
In order to put this into slope-intercept form, we simply need to subtract 2x from both side.s
3y = 6 - 2x
Then, divide both sides by 3 so that we fully isolate y.
3y ÷ 3 = (6 - 2x) ÷ 3
Simplify.
y = 2 - 2/3x
Put this into order by moving "x" onto the correct place.
y = -2/3x + 2
Therefore -2/3 is the slope, as it is in the "m" spot.
Hope I helped! :)
The first one is right and the third one is right, but you need to switch the 15% and the 95%.
In #2, it's asking for the kids that <em>are not</em> Michael, so it'd be 18/19. Which is then rounded to roughly 95%.
#4 asks for 6/40 = 15%
