Answer:

x=sqrt of 12

Step-by-step explanation:

First, you divide by 9 on both sides:

x^2= 108/9

Then you solve that:

x^2 = 12

Then you find the root of both sides:

sqrt (x^2)= sqrt (12)

and you get:

x= sqrt of 12 which is about 3.46... OR 2√3

Answer:

Shifted by 6 units left on the x-axis.

Step-by-step explanation:

Given function is,

f(x) = 5ˣ + 1

After transformation, this function becomes g(x) = $5^{(x+6)}+1$

Here, g(x) = f(x + 6)

By the rule of transformation,

Function 'f' has been shifted by 6 units left on the x-axis to form a new function 'g'.

Answer:

A- X= 20÷5-3

B- 20÷5=4; 4-3=1

C- X=1

Step-by-step explanation:

Okay, well we have to work backwards. 20 cookies, and she makes 5 bags. We need to find out what 'x' means. To do that, we take 20 cookies and divide it by 5. 4 cookies. Then we want to take 3 cookies out of each bag to find out how many cookies she first put in. 1 cookie.

Let's check:

bag 1:

o (one cookie)

bag 2:

o (one cookie)

bag 3:

o (one cookie)

bag 4:

o (one cookie)

bag 5:

o (one cookie)

Now we have 15 cookies left. Now let's put 3 in each:
