Answer:
Use the formula π*(r^2) where r is radius
Area of big circle, all 3=314.1592654 (approximately) and this is =100%
Area of middle circle=153.93804
Area of small circle=78.53981634
Percentage of middle circle with small circle = (153.93804/314.1592654)*100= 48.999999999999 approx= 49%
Percentage of small circle alone = (78.53981634/314.1592654)*100
= 25%
So 51%= big circle alone
And 51%+25%= 76%
100%-76%=24%
Since y=mx+b is the slope-intercept form of a line, where m=slope and b=y-intercept, we can see that:
The y-intercept is 5 (technically the point (0,5))
The x-intercept occurs when y=0 so:
2x+5=0
2x=5
x=2.5
So the x-intercept is the point (2.5, 0)
