Consider the function represented by 9x+3y= 12 with x as the independent variable. How can this function be written

Brums [2.3K]

Well, function is already written in "function notation" though not explicitly which I assume is "function notation".

Explicit notation for this function is:

$f(x)=4-3x$

Hope this helps.

What is the average (arithmetic mean) of the first 90 measurements in a certain list of 92 measurements? (1) the average of the

marishachu [46]

The sum of all the measurements is just the average times the number.

$\bar x = \frac{1}{n} \sum_{i=1}^n x_i$

$\sum_{i=1}^n x_i = n \bar x$

So if the average of all 92 is 7 the sum of those is $92 \times 7$

The average of the last two is 7.2 so their sum is $2 \times 7.2$

That means the sum of the first 90 is $92 \times 7 - 2 \times 7.2$

so the average of the first 90 is

$\dfrac{92 \times 7 - 2 \times 7.2}{90} = 6.99556$ cm

F(x)=x^2=10x+35 what is the value of h when the function is converted to vertex form

puteri [66]

I hope this helps you

y=x^2-10x+35

y=x^2-10x+25+10

y-10=(x-5)^2

y=(x-5)^2+10

h= -(-5)=5

k =10
