Question

.

Answer 1

ok for number 11 use the distance formula \[d=\sqrt{(x2-x1)+(y2-y1)2}\] sub both A(-1,0) and B(5,8) into that equation.

Answer 2

and number 12 u use the midpoint formula (x1+x2)/2 (y1+y2)/2
to get x value y value

Answer 3

the only steps u have to do are sub in the correct values into the formulas.

Answer 4

ok for question 11 \[d= \sqrt{((5-(-1))^2+(8-0)^{2}}\]
\[d= \sqrt{6^{2} + 8^{2}}\]
\[d = \sqrt{36 + 64}\]
\[d=\sqrt{100}\]
d = 10

Answer 5

when i stated the distance between two formulas b4 i forgot the ^2 around the x^2 bracket but the working out is correct.

Answer 6

so for question 12 a(-1,0) and b(5,8)
\[(-1+5)/2\] and \[(0+8)/2\]
4/2 8/2
2 4
x-value y-value
so mid point is at the coordinates (2,4)

Answer 7

omg. i love you. thank you so much.

Answer 8

haha it's okay. as long as u understand how to do it :)
