<span>X^2- 4x- 6y- 14=0
6y = x^2 - 4x - 14
Divide through by 6:-
y = (1/6)x^2 - (2/3)x - 7/3</span>
It’s C because
3*2 - 2* -1 =8
6+2=8
8=8
3) adjacent
x = 180 - 34 = 146
4)adjacent
x = 90 - 74 = 16
6)supplementary
2x + 5 + 75 = 180
2x + 80 = 180
2x = 100
x = 50
2 miles per hour
all you have to do is multiply 1/3 by 6 since she only walks 1/3 miles in 1/6 of an hour and you want to find the miles walked in a hour<span />
First, substitute 6 in for x:
5 x 6^2 + 6 - 7
Simplify:
30^2 + 6 - 7
30^2 + 1
900 + 1
901
Hope this helps!!
