30. Set up a proportion of 6/2 and x/10. cross multiply 6 times 10 and you get 60. divide 60 by 2=30

7x - 5y = 22<br> 7x - 9y = 6<br> What's y?

Vesna [10]

You can do this by taking away the second equation from the first to get rid of the x terms so:

7x - 7x = 0
-5y - -9y = - 5y + 9y = 4y
22-6 = 16

So you are left with the equation:
4y = 16

Divide both sides by 4 to find y
y = 4

Find the average rate of change of the function

8090 [49]

The average rate of change from an interval from $x_1$ to $x_2$ is the change in the value of the function divided by the change in x.

$\dfrac{f(x_2)-f(x_1)}{x_2-x_1}$

Let's find the values of $f(x_1)$ and $f(x_2)$

$f(x_1)=4^2+3(4)=28$
$f(x_2)=9^2+3(9)=108$

$\dfrac{f(x_2)-f(x_1)}{x_2-x_1}$

$=\dfrac{108-28}{9-4}=\boxed{16}$

Your answer is 16. I hope this helps and have an awesome day! :)
