When you are looking for a fraction, it is best to convert this into a percentage, which in this case, is 80%. Following on from this, you will have to round the number up, which in this case, will be to 200- however, depending on the number, this could be different. From this, you then have to find 80% of 200. From this, you then have to divide 200 by 10, giving you 20, and then multiply this by 8, to get 160, and this is a good estimate for 4/5 of 192. Hope this helps you <span />
Step-by-step explanation:
Let x=3.
So, f(3-3)=f(3)-f(3), and thus f(0)=0.
Answer:
-4(3-1)+2
-4x2+2
-8+2= -6
since there is only one - and one + the answer will be negative
Answer:
It is the easiest way to graph an equation.
Step-by-step explanation:
Isolating the y variable is also slope-intercept form.
Slope intercept form is the easiest form to use when graphing.
y = mx + b
m is the slope, b is the y-intercept.
it makes it way easier to graph an equation when it is in slope intercept form.
I hope that helps! =)
You don't use it usually because teachers usually say use 3.14 as an approximation
