Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ 3, 6 ] , then

f(b) = f(6) = 6² + 3(6) + 2 = 36 + 18 + 2 = 56

f(a) = f(3) = 3² + 3(3) + 2 = 9 + 9 + 2 = 20 , then

average rate of change = $\frac{56-20}{6-3}$ = $\frac{36}{3}$ = 12

A local hamburger shop sold a combined total of 578 hamburgers and cheeseburgers on Tuesday. There were 72 fewer cheeseburgers s

andreev551 [17]

Let h be hamburgers and c be cheeseburgers.
We know that $h + c = 578$
We also know that $c + 72 = h$
This gives us a system of equations we can solve. My preferred method to solve systems is substitution, where we solve one equation for one of the variables, then substitute that solution in the other equation, reducing it to a single variable equation. One of the equations already equals h, so we can go straight into the sub part.
$h + c = 578$
$(c + 72) + c = 578$
$c2 = 506$
$c = 253$
Finally, we go back to the other equation and solve for h.
$c + 72 = h$
$253 + 72 = h$
$325 = h$
So, total there were 253 cheeseburgers sold, and 325 hamburgers sold.

Is the relation ship shown by the data linear? if so model the data with an equation pls help

svet-max [94.6K]

It is not linear. Check to see if the points fit in any of the equations. Use 3 for x and 1 for y. None of them work. You get false statements like 3=1.
