<u>Given</u>:

Given that the graph of the quadratic function.

We need to determine the value of a in the function's equation.

<u>Value of a:</u>

The value of a can be determined using the formula,

y=a(x-h)^2+k

where (h,k) is the vertex and a is a constant.

From the graph, it is obvious, that the vertex of the parabola is (0,9).

Thus, substituting the vertex (h,k) = (0,9) in the above formula, we get;

y=a(x-0)^2+9

y=ax^2+9  -------- (1)

Let us substitute any one of the coordinate that the graph passes through to determine the value of a.

Let us substitute the point (3,0) in the equation (1), we have;

  0=a(3)^2+9

  0=9a+9

-9=9a

-1=a

Thus, the value of a is -1.

Hence, Option B is the correct answer.

Write an equivalent expression to present patricia total earnings this week 7h + 135 + 5h = ?h + ?​
Paul [167]

Answer: 12 h + 135

Step-by-step explanation: 7h +135 + 5h = ?h + ?​

                                             7h +5h +135  

                                            =12h +135

So u combine like terms together  which are 7h and 5h which gives you 12 h.And then you have 135 left,so you add 12h to 135.

Ps.If you don't know what like terms are.I will explain down below.

Like terms are  variable that are the same.For an example 4y and 3y are like terms .Another example is 1/3 xy and 6xy .

Hope this helps :) and if it does please give brainliest .

Evaluate 3^2 + (7 − 2) ⋅ 4 − 6 over 3
goldfiish [28.3K]

Answer:

7.7

Step-by-step explanation:

we basically follow the BEDMAS rule

1st we workout the bracket (7-2)=5

2nd the exponent 3^2=9

3rd the multiplication (7-2) . 4 = 5 . 4 = 20

4th addition 9+20=29

5th step is subtraction 29-6=23

the final step is dividing 23 by 3, which will become 7.7
