distance formula
(x1-x2)^2 + (y1-y2)^2 = d^2
(4-1)^2 + ( x-3)^2 = 5^2
9 + (x-3)^2 = 25
(x-3)^2 = 16
x-3 = 4
x = 7
x = three length
x + x + x + x+15 + x+15 = 250
5x +30 = 250
5x = 220
x = 44 x+15 = 59 cm

10000
2-1 = 1
4-3 =1
6-5 =1
.
20 000 - 19999 = 1 10,000 ones = 10 000
Sumn = a(rn-1) / (r-1) a = 1/4 r = 1/2 Sum = 63/128
sub in these values and solve for 'n'..... Let me know if you get stuck
The slope of the new line will be the same : 1/2
so answer A or B Substitute in the point given 4, -1 to see which one it is .....
parallel slope is still 1/2
so answer A or B sub in the point 4, -1 into each of them to find which one it is....
Here is one 9999 - 4360 = 5639
2x = 5y multiply by 7/5
14/5 x = 7y
14/5 x = 11z
14/5 /11 = z/x
14/55 = z/x
-2x^2 + 6x - 8
-2 (x^2-3x) - 8
-2 (x^2 - 3x + 2.25) + 4.5 - 8
-2 (x- 1.5)2 - 3.5
