Question is Incomplete;Complete question is given below;
Caleb made $105 mowing lawns and walking dogs, charging the rates shown. If he mowed half as many lawns as dogs walked, how many lawns did he mow and how many dogs did he walk? $7.50 for walking dogs and $20 for mowing lawns
Answer:
Caleb mowed 3 lawns and walked 10 dogs.
Step-by-step explanation:
Let the number of dogs he walked be 'd'.
Let number of lawn he mowed be 'l'.
Given:
If he mowed half as many lawns as dogs walked
So we can say that;
Now given:
Cost for mowing each lawn = $20
Cost for walking each dog = $7.50
Total amount made = $105
Now we can say that;
Total amount made is equal to Cost for mowing each lawn multiplied by number of lawn he mowed and Cost walking each dog multiplied by number of lawn he mowed.
framing in equation form we get;
Substituting equation 1 in equation 2 we get;
Applying distributive property we get;
Dividing both side by 17.5 we get;
Substituting the value of 'd' in equation 1 we get;
Hence Caleb mowed 3 lawns and walked 10 dogs.
Answer: To find the excluded value in the domain of the function, equate the denominator to zero and solve for x .
Step-by-step explanation:
For example, in the problem below The domain of the function is set of real numbers except −3 . The range of the function is same as the domain of the inverse function. So, to find the range define the inverse of the function.
