<span>15x-3y=27
5x+4y=14
multiply (2nd) equation by (3)
15x + 12y = 42
</span>15x - 3y=27
15x + 12y = 42
-------------------substract
-15y = -15
y = 1
15x-3y=27
15x-3(1)=27
15x - 3 = 27
15x = 30
x = 2
so now you have x = 2, y =1
answer <span>D. (2,1)</span>
The vertex form is
where (h,k) is the vertex, and a is the coefficient.
On the graph, the vertex is point (2,0), so our vertex form is
which is answer D. We remove the a, since the parabola is not stretched, just shifted.
One way of approaching this problem would be to convert both measurements into inches.
7 ft 6 1/2 inches = 84 inches + 6.5 inches = 90.5 inches
2 5/8 inches x 2 = 4 10/8 inches, or 5 2/8 inches, or 5.25 inches
Adding these two results together produces 95.75 inches.
Let, numbers = x,(x+2),(x+4),(x+6)
A.T.Q,
x+x+2+x+4 = x+6+18
3x+6 = x+24
3x-x= 24-6
2x = 18
x = 9
Numbers would be 9, 11, 13, 15
