Find the equation, (f(x) = a(x - h)2 + k), for a parabola containing point (2, -1) and having (4, -3) as a vertex. What is the s
postnew [5]

Given that the vertex of the parabola is (4,-3)

The parabola passes through the point (2,-1)

We need to determine the standard form of the equation of the parabola.

<u>Standard form of the equation of the parabola:</u>

The standard form of the equation is y=a(x-h)^2+k where the vertex is (h,k) and a is the constant.

Substituting the vertex (4,-3) in the above equation, we get;

y=a(x-4)^2-3  ---------------(1)

Substituting the point (2,-1) in the above equation, we have;

-1=a(2-4)^2-3

-1=a(-2)^2-3

-1=4a-3

  2=4a

  \frac{1}{2}=a

Thus, the value of a is \frac{1}{2}

Substituting the value of a in the equation (1), we get;

y=\frac{1}{2}(x-4)^2-3

Thus, the standard form of the equation of the parabola is y=\frac{1}{2}(x-4)^2-3

How do you solve <br>m=q/z-v solve for z
g100num [7]
Hello!

To solve whatever z is we have to get it by itself by using inverse operations. I will undo operations below.

m=q/z-v+v
m+v=q/z(z)
m+v+z=q
m+v+z-z=q-z
m+v=q-z
Here I will switch z to adding negative z so we can use the commutative property.
m+v= q+(-z)
m+v=-z +q
m+v-q=-z+q-q
m+v-q=z

We now have our formula for z. z=m+v-q. Hope this helps!

Mr.Curry soent 1/3 of his paycheck on bills and 1/6 on food
yaroslaw [1]
$300 = 1/6
1/3 is 1/6 times two
$600 = 1/3

1/3 = 2/6

3/6 = $900 ( Bills and Food )
So, he has 3/6 left, which is also $900
900 + 900 = 1800

Mr. Curry received 1,800 dollars in his paycheck and spent $600 dollars on bills.

Solve linear equation x+3+x-8+x=55
Andru [333]
First you add like terms which means you add all the x's together and all the constants.
3x -5 =55 (Remember that 8 has a negative sign in front which brings that sign with it when combinding like terms)
Then you isolate the variable by adding 5 on both sides.
3x = 60.
Finally you divide by 3 on both sides to get x=20

Use the graph that shows the solution f(x) = G (x)
Bingel [31]

Answer:

The correct options are A and C.

Step-by-step explanation:

The given functions are

F(x)=-\frac{3}{4}x^2+3x+1

G(x)=2^x

We have to find to solution for the equation

F(x)=G(x)

-\frac{3}{4}x^2+3x+1=2^x

The solution of the above equation is the intersection of F(x) and G(x).

From the graph it is noticed that both graph intersects each other at (0,1) and (2,4).

The x-coordinates of these points are the solutions of the given equation.

Therefore the solution of given equation are 0 and 2.

Therefore option A and C are correct.
