What are the solutions to the equation 3(x-4)^2=27

Rom4ik [11]

Answer:

x=1, x=7

Step-by-step explanation:

Firstly, you can simplify by dividing both sides by 3, which will make the equation easier to simplify:

(x-4)^2=9

Next, you can take the square root of each side, which will cancel the square, and make the 9 even easier to work with:

(x-4)=(± )3

*Note the (± ) sign, this is because there is a positive and negative answer*

After this, you will basically have two equations:

(x-4)=3

and

(x-4)=-3

You are going to solve both to get both answers, but lets start with the positive first:

x-4=3 Add 4 to both sides to get an x= equation

And it's the same thing for the negative:

x-4=-3 Add 4 to both sides to get an x= equation

Hope this helps

How to estimate 5 2/11- 3 2/18

Nimfa-mama [501]

Answer: The estimated value is: " 2.1 " .

__________________________________

Step-by-step explanation:

__________________________________

We are asked to "estimate" :

5 2/11 - 3/ 2/18 ;

Note: Consider: " 5 2/11 " ;

Note that: "2/11" is close to: "2/10" ; which can be expressed as a decimal value: "0.2 " ;

So, consider this value: "5 2/11 "; as estimated: " 5.2 " .

Now, consider: " 3 2/18 " ;

Note that : "2/18" can easily be reduced to: "1/9 ";

Since: "(2/18)" = "(2÷2) / (18÷2) " = "1/9 " ;

Note that "1/9" is close to "1/10" ; which can be expressed as a decimal value: "0.1 ".

So, consider: "3 2/18 " ; as estimated: " 3.1 " .

__________________________________

So: To estimate: " 5 2/11 - 3 2/18 " ;

__________________________________

Use the following: "5.2 - 3.1 " ;

__________________________________

5.2

- 3. 1

__________________________________

" 2.1 "

___________________________________

The estimated value is: " 2.1 " .

The graph of the function, B(x), is shown below. Determine the following values for the function:

Softa [21]

Answer:

$B(-1) = 1\\\\B(3) = 0\\\\B(1) =2$

Step-by-step explanation:

By definition, a relation is a function if each input value has one and only one output value.

The input values are the x-values and the output values are the y-values.

Given:

$B(-1),B(3)$ and $B(1)$

We can identify that we need to find the output values of these input values:

$x=-1\\x=3\\x=1$

Observe in the graph attached that:

When $x=-1,\ y=1$

When $x=3,\ y=0$

When $x=1,\ y=2$

Therefore:

$B(-1) = 1\\\\B(3) = 0\\\\B(1) =2$
