You mean by subtraction, right?
The slope intercept equation of the line above is y=-2x+3
It is 8 percent of 50.
This is 1 way-
<span>4/50=%/100 You now have a proportion. Cross multiply.
50%=400 Replace % with any variable.
50x=400 Now divide both sides of the equation by 50.
x=8
</span><span>
(% is basically the percentage of 4 of 50 over 100. its much easier to solve </span>percentage problems when the percentages are over 100. 100 represents a full percentage.
example- 4 of 100 is 4% of 100)
2nd example-
Since the percentage can be found if over 100 as well (%/100), and since 100 is a multiple of 50, we can do 4 of 50 (which would look like 4/50) and multiply both numbers by 2 to get the percentage. These are our steps:
<u />4/50× 2/2=
8/100
Therefore, 4 of 50 is 8% of 50
Answer:
<em>Hello There If you want to learn of the equation of the circle. Look at the circle first then.. The center-radius form of the circle equation is in the format will help you from that point. with the center being at the point (h, k) and the radius being "r". This form of the equation is really helpful, since you can easily find the of center and the radius.</em>
Hope it helps!
