If x= -1
so.
2(-1)^2-5 / (-1 +9)
=-3/8
=-0.375
the answer is C). y= 1/4x + 2
Answer:
B
Step-by-step explanation:
Given a quadratic function in standard form
y = ax² + bx + c ( a ≠ 0 )
• If a > 0 then the graph opens upwards
• If a < 0 then the graph opens downwards
y = x² + 5x + 6 ← is in standard form
with a = 1 > 0
The graph therefore opens upward
Look up a Pizza Place Online; with a website preferably
Find the cost and diameter of each size (should be in any pizza menu)
Divide the diameter by the cost (Cost/Diameter)
ex: 4.99/12
=0.415833333 per inch
Do this for all the sizes and compare each of the sums.
The one with the lowest cost per inch would be the best deal.
Hope this helps!
