Answer:
Value of a is 2
Step-by-step explanation:
Given the equation of the quadratic function represented by the graph is
. we have to find the value of a.
As seen in the figure, parabola cuts the graph at point (2,1) implies point (2,1) is one of the solution of the given quadratic equation i.e of given parabola.
∴ Point (2,1) satisfies the given equation.
Hence, we can find the value of a by putting the value of x and y, we get

⇒ 
Hence, the value of a is 2
the only thing that get the closest is 28,056
Subtracts 150 each time—
950-150=800 and 800-150=650 and so on and so forth. The number sequence only includes 5 numbers so there is no way to tell if there is a tougher solution.
Answer: $357 is more amount budgeted for food increase.
Explanation:
Since we have given that
Number of people according to the budget = 150
Cost of food per person= $4.25
Total cost of food is given by

If the number of guests attending the opening was 56% more than expected,
So, number of guests now is given by

Total cost of food is given by
Difference between them is given by

Hence, $357 is more amount budgeted for food increase.
Answer:
EC/BC = DE/AB
Step-by-step explanation:
There are multiple answers for this, but this should work as well. EC is proportional to BC, and AB is proportional to DE, so one answer is: EC/BC = DE/AB
