In short, Your Answer would be Option B
Hope this helps!
blank = exponential growth.
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
<u>x=7</u>
And it's the same thing for the negative:
x-4=-3 Add 4 to both sides to get an x= equation
<u>x=1</u>
Hope this helps
Answer:
yes
Step-by-step explanation:
each input is put with only one output therefore it is a function
The school council will have 216 small sandwiches.
Step-by-step explanation:
Sandwiches ordered = 12
Length of one sandwich = 6 feet
1 foot = 12 inch
6 feet = 12*6 = 72 inches
Length of one sandwich in inches = 72 inches
As one small sandwich is 4 inches,
Number of small sandwiches in one sandwich = 
One sandwich = 18 small sandwiches
12 sandwiches = 18*12 = 216 small sandwiches
The school council will have 216 small sandwiches.
