Jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A rat weighs

brilliants [131]

Answer:

The slope is $s =$ $0.1774 / pounds

Step-by-step explanation:

From the question we are told that

The weight of the rat is $w_1 = 3.5 \ pound$

The cost of feeding the rat per week is $c_1 =$ $4.50

The weight of a Beagle is $w_2 = 30 \ pound$

The cost of feed a Beagle per week is $c_2 =$ $9.20

Now the slope can be evaluated mathematically as

$s = \frac{c_2 -c_1 }{w_2 -w_1 }$

substituting values

$s = \frac{9.20 -4.50 }{30 -3.5 }$

$s =$ $0.1774 / pounds

stira [4]

$p(x)=x^2-x-6$

$q(x)=x-3$

$p(x)-q(x)=x^2-x-6-(x-3)=x^2-x-6-x+3=\boxed{x^2-2x-3}$

The answer is C.

Hope this helps.
