Answer:
Hot Dog and Bologna
Step-by-step explanation:
618+5400=6018
6018+(50+2500)=8568
8568-(47+2900)=5621
she has $5,621 in her account
The denominator is 14-x.
Since the denominator cannot be equal to zero, you take the denominator, set it equal to zero, and solve.
This ill give you the value or values that must be eliminated (cannot be in the domain).
14 - x = 0
add x to both sides
14 = x
The domain is x ≠ 14
OR
(- ∞, 14) ∪ (14, ∞)
OR
All real numbers except 14
<span>The first part of the quadratic formula, x = - b/2a, is the equation of the axis of symmetry, and the x-coordinate of the vertex. </span>
<span>In standard form: - 2x² + 8x - 5 = 0, a = - 2, b = 8, c = - 5 </span>
<span>The axis of symmetry: x = - 8/2(- 2) = - 8/- 4 = 2 </span>
<span>Go back and solve for y to find the y-coordinate of the vertex. </span>
<span>y = - 2(2)² + 8(2) - 5 </span>
<span>y = - 2(4) + 16 - 5 </span>
<span>y = - 8 + 16 - 5 </span>
<span>y = 3 </span>
<span>Vertex is (2, 3)</span>
