Answer: 7/21 is the answer because 7 * 2 = 14 and 21*2=42
Step-by-step explanation:
The anser for 6 is 25/92
The answer for 7 is 1 1/2
To get the answer you need to multiply 1,000 by 7.15 then move your decimal to make it accurate and you should end up with 7150

Answer: b = 4 and c = 7.</h3>
===============================================
Explanation:
Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.
The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.
Plug those three values into the vertex form below
y = a(x-h)^2 + k
y = 1(x-(-2))^2 + 3
y = (x+2)^2 + 3
Then expand everything out and simplify
y = x^2+4x+4 + 3
y = x^2+4x+7
We see that b = 4 and c = 7.
