Frank needs a total of $360 to cover his expenses for the week. He earns $195 a week working at a restaurant and also walks dogs to supplement his income. Frank charges $15 per dog that he walks.

Besides his $195 weekly income he would have to walk 11 dogs at a charge of $15 each to cover his total expense of $360.

Step-by-step explanation:

$360 - $195 = $165 remaining expense to be covered.

$165 / $15 = 11 walks

Therefore he needs to do 11 dog walks at a rate of $15 plus his restaurant earnings to complete $360.

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.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
