<h3>
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.
The equation you would use would be (1/8)*200 which equals 25. To get this answer you multiply the volume by the quantity of cubes.

train distance + plane distance = 1300 miles
50x + 275x = 1300
x(325) = 1300
x = 4 hours
4x2=8

Answer:
To what
Step-by-step explanation:
Answer:
x = 50
Step-by-step explanation:
SU is a midline segment and is one half the measure of VW, thus
VW = 2SU , that is
x - 46 = 2(x - 48) ← distribute
x - 46 = 2x - 96 ( subtract x from both sides )
- 46 = x - 96 ( add 96 to both sides )
50 = x
