The first week of January, there are 49 dogs and 28 cats in an animal shelter. Throughout the month the ratio of dogs to cats remains the same. The last week of January there are 20 cats in the animal shelter. How many dogs are there?

35 dogs

Step-by-step explanation:

We can simplify the ratio 49:28 by dividing by 7

The new ratio is 7:4 which is easier to work with.

It says there are 20 cats so we know that for every 4 cats there are 7 dogs

We simply multiply 20 by 7/4

20 x 7/4 = 35 so  there are 35 dogs

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
