Work out the following, giving your answers in their simplest form: 4 2/5 ÷ 1 1/5
Black_prince [1.1K]

Answer:

First make mixed

4 x 5 = 20

20 + 2 = 22

22/5 = 4 2/5

1 x 5 = 5

5 + 1 = 6

6/5= 1 1/5

Multiply the reciprocal. The reciprocal is the fraction flipped over like 1/2 becomes 2/1

22/5 / 6/5 = 22/5  x 5/6

Multiply

22 x 5 = 110

5 x 6 = 30

110/30

Simplify

110/10=11

30/10=3

Answer is

11/3 = 3 2/3

So first you got to simlipy both sides of the equation.Like this:

10x-3x+2=6x+6

7x+2=6x+6

Then you have to move the variables to one side and the other nums to the other side:

7x-6x = 6 -2

Then you have to simplify.

x = 4

What quadratic function does the graph represent?
nekit [7.7K]

Answer:

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

Step-by-step explanation:

The function of the graph can be written in the vertex form as

f(x)=a(x-h)^2+k, where V(h,k)=V(2,4) is the vertex of the quadratic function.

We substitute the value to obtain;

f(x)=a(x-2)^2+4,

The point (5,1) lies on the graph so we use it to determine the value of a.

1=a(5-2)^2+4,

1-4=a(3)^2,

-3=9a,

a=-\frac{1}{3}

The required equation is

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