Which inequality does the graph below represent?
Dima020 [189]

Answer:

A. y\le2x^2-8x+3

Step-by-step explanation:

The given parabola has vertex at (2,-5).

The equation of this parabola in vertex form is given by:

y=a(x-h)^2+k, where (h,k)=(2,-5) is the vertex  of the parabola.

We substitute the values to get:

y=a(x-2)^2-5

The graph passes through; (0,3).

3=a(0-2)^2-5

\implies 3+5=4a

\implies 8=4a

\implies a=2

Hence the equation of the parabola is

y=2(x-2)^2-5

We expand this to get:

y=2x^2-8x+8-5

y=2x^2-8x+3

Since the outward region was shaded, the corresponding inequality is

y\le2x^2-8x+3

The correct answer is A

I need to write a problem for this equation 3(2x-5)=24
o-na [289]

Answer:

Three times the difference of two times a number and five is equal to 24, what is x?  

Step-by-step explanation:

To write any equation in word problems, it is important to identify all your parenthesis operations by their technical names. Subtraction is a difference. So since we are multiplying it by 3, it becomes three times a difference.

A grocery delivery service has 22 members. Each member pays monthly dues of $12.80
slava [35]

Answer:

C

Step-by-step explanation:

If 9 members paid on the first day, this means they did not pay on the third day

The remaining people (everyone but the 9) paid on the third day

Therefore we must subtract to find out how many members paid on the third day

22 - 9 = 13

Each of the 13 members paid $12.80 which means we must multiply

13 × 12.80 = 166.40

In total, the grocery store collected $166.40 on the third day of the month
