Answer:

he age of girl 3 \frac{1}{2} years ago is 8.5 years  .

Step-by-step explanation:

Given as :

The present age of seventh grader girl = 12 years

Let The age of her 3 \frac{1}{2} years ago = x years

So The age of girl \frac{7}{2} years ago = x years

<u>Now, According to question</u>

The age of girl 3.5 years ago = 12 - 3.5

Or,  The age of girl 3.5 years ago = 8.5 years

Hence The age of girl 3 \frac{1}{2} years ago is 8.5 years  . Answer

Hey there!

This equation we're given is a function. This means that we will get a certain output for each input. If your input is x, the output, or y, will be 0.3 of x plus 11.8. It appears that the independent variable (our x) is the age in the table and the height of the jump is the dependent variable (our y). We can plug some of the data into our function and see if it is true! We will use the first two columns of the table to test this out.

--------------------------------------------------------------------------------------------

                                                   Column 1

Age: 22

Height of Jump in Inches: 15.4

15.4=0.3(22)+11.8

15.4=6.6+11.8

15.4=18.4

This is equation is false, so this data point does not match the given function. We can check with one more column just to make sure, but just given this we immediately know that the given equation is not a good fit for the data.

--------------------------------------------------------------------------------------------

                                                   Column 2

Age: 24

Height of Jump in Inches: 17

17= 0.3(24)+11.8

17=7.2+11.8

17=19

This is equation is also false.

--------------------------------------------------------------------------------------------

Therefore, this equation is not a good fit for the data given.

I hope that this helps! Have a wonderful day!

A sequence is defined recursively by the formula f(n + 1) = f(n) + 3 . The first term of the sequence is –4. What is the next te
sergiy2304 [10]
Translate the equation to math.
It says the term after the current term is the current term plus 3.
Next term = this term + 3
Next term = -4+3
The next term is then -4+3 or -1.

Answer= - 1

Hope this helps :)
