2x-2y over 36-3x when x=7 and y=2 please show work

1 answer:

5 0

(2x-2y)/(36-3x)

So now you sub in the variable into the equation
(* means multiply in this case because x would make it more confusing)

((2*7)-(2*2))/(36-(3*7))
= (14-4)/(36-21)
= 10/15
then you can reduce the fraction to 2/3
so the answer is 2/3 or if you want to put it in a decimal, 0.67

Find a power series for the function, centered at c. f(x) = 1 9 − x , c = 4 f(x) = [infinity] n = 0 Incorrect: Your answer is in

Wewaii [24]

Looks like the given function is

$f(x)=\dfrac1{9-x}$

Recall that for |x| < 1, we have

$\displaystyle\frac1{1-x}=\sum_{n=0}^\infty x^n$

We want the series to be centered around $x=4$ , so first we rearrange f(x) :

$\dfrac1{9-x}=\dfrac1{5-(x-4)}=\dfrac15\dfrac1{1-\frac{x-4}5}$

Then

$\dfrac1{9-x}=\displaystyle\frac15\sum_{n=0}^\infty\left(\frac{x-4}5\right)^n$

which converges for |(x - 4)/5| < 1, or -1 < x < 9.

A cookie contains 9 grams of fat. If you eat no fewer than 4 and no more than 7 cookies, how many grams of fat will you

Hitman42 [59]

Step-by-step explanation:

Since each cookie has 9 grams of fat, four cookies would contain 4*9 = 36 grams of fat.

Also nine cookies has 7*9 = 63 grams of fat.

So the number of grams consumed will be at least 36 and no more than 63.

Remove the parentheses from the following expression, and combine like terms: 3(ax + b2 – c) + 2

expeople1 [14]

Hi, Eswoody01! :)

To remove the parenthesis, we must distribute them:
$3(ax + b^2 - c) + 2$
$3*ax+3*b^2-3*c + 2$
Simplify.
$3ax+3b^2-3c + 2$

This is the most you can simplify this expression.

Hope this helps.
