Answer:
D) 26/48
Step-by-step explanation:
/ = division sign
26/48 also means 26 divided by 48.
Simple math.
C - no solution
you take the second solution and times the entire equation by -1
then simply
and you get 0x + 0y = 20
312* 17.5= 5460.00
134*19=2546
2546+5460= $8,006.00
Let's first rewrite it in vertex form.
Start by completing the square.
y = x² + 4x + 4 - 4 - 1
y = (x + 2)² - 5
(x + 2)² = y + 5
Now, 4a = 1; a =

So, the vertex form is (x + 2)² = 4(

)(y + 5)
So, we know that the vertex is at (-2, -5).
Since it's a concave up parabola, we just have to change the y-value to find the focus.
∴ F(-2, -5 +

)
F(-2,

)
