1 answer:

5 0

Find slope
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given (
(5,19) and (9,23)
slope=(23-19)/(9-5)=4/4=1

slope=1

equation with point (x1,y1) and slope is m is
y-y1=m(x-x1)
given
(5,19)
y-19=1(x-5)
y-19=x-5
y=x+14

HELP PLEASE BEST ANSWER WILL BE MARK AS BRAINLIEST!

First of all,
The total weight of the six dogs are:
71+34+15+23+18+56=217 pounds
Then, we know that the average weight of the seven dogs are 40 pounds, so the total weights of the seven dogs are:
40×7=280 pounds.
Lastly, we know that the six dogs weights are 217 pounds and the total weight of the seven dogs are 280 dogs, so the seventh weight of the dog is:
280-217=63 pounds. As a result, the seventh weight of the dogs at the vet is 63 pounds. Hope it help!

The area (A) of a circle is a function of its radius (r) and is given by the function A=f(r)=pie r^2. What is the domain of this

Alenkinab [10]

All positive real numbers. in this function, the domain is the radius. all real numbers includes negative numbers, and u cant have a negative distance. you also cant have a radius of 0 because the circle wouldnt exist. and u can have a fraction domain, so A is the answer
