3b<40 because no matter what the price cannot be over 40 because she only has 40
Answer:
x-intercept (s):
For this case h (x) = 0
x2 - 2x - 8 = 0
(x-4) * (x + 2) = 0
x1 = 4
x2 = -2
y-intercept:
For this case x = 0
h (0) = (0)2 - 2 (0) - 8
h (0) = - 8
vertex:
We derive the equation:
h '(x) = x2 - 2x - 8
h (x) = 2x - 2
We match zero:
2x-2 = 0
x = 2/2
x = 1
We evaluate the function for x = 1
h (1) = (1)2 - 2 (1) - 8
h (1) = 1 - 2 - 8
h (1) = -9
The vertex is:
(1, -9)
axis of symmetry of the function:
x = 1

Multiply the denominator by the number in front of it and then add it to the numerator. (6•2=12+5=17). The denominator stays the same. Your answer is 17/6. Hope this helped!
Answer:
O x >9
The arrow points left
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<em>Given 2 < x-7</em>
<em>adding '7' on both sides, we get</em>
<em>⇒ 2 + 7 < x -7 +7</em>
<em>⇒ 9 < x</em>
<em>⇒ x>9</em>
<em>Given inequality 2 < x -7</em>
The arrow points left
<u><em>Final answer</em></u>:-
solution is x >9
The arrow points left
