Mathematics

Marina CMI [18]3 years ago

For this case we have a function of the formy = f (x)

Where:

f (x) = - 4x + 3

We must find the value of the function when the variable x is -5.

Then, substituting, x = -5

f (-5) = - 4 (-5) +3

We have that by sign law- * - = +

f (-5) = 20 + 3\\f (-5) = 23

Answer:

f (-5) = 23

ANSWER

f( - 5)=23

EXPLANATION

The given function is

f(x)=-4x+3

To find f(-5), we substitute x=-5 to obtain;

f( - 5)=-4( - 5)+3

We multiply out to obtain:

f( - 5)=20+3

We simplify to get,

f( - 5)=23

Dr. Wong has a table of data in her veterinary office that shows the average lifespans and weights of several popular dog breeds
belka [17]

Answer:

1. The heavier the dogs are, the shorter lifespan they have.

2. The lifespan of a bloodhound is on average 10 years long

3. Number 2

Step-by-step explanation:

#1 explination: Since its obvious that the graph angles downwards as it goes towards the left, and because as you go to the left you get heavier dogs, put 2 and 2 together and you get my answer.

#2 explination: We see 3 dots around 90 pounds, one that lives 11 years, and 2 that live 10 years. Since we need to be accurate, we need to find the average of 10, 11, and 10. (10+10+11)/3=10.33. Now we round to 10, so 10 is our answer.

#3 explination: Since there is a bloodhound that lives to be 14, we have two answers, 2 or 3. 1 doesn't work since if Alfonso doesn't have good estimation, the first two questions wouldn't matter *the more you know*. Since we see no unusual pattern between any of the three dots I mentioned earlier, Dani must of forgotten her dog's age (probably because of that dog years thing.)
