5
Answer:
[tex]\boxed {21}[/tex]
Step-by-step explanation:
Find [tex]g(5)[/tex]:
[tex]g(x) = x^{2} - 4[/tex]
-Apply [tex]5[/tex] for variable [tex]x[/tex] to the equation:
[tex]g(5) = (5)^{2} - 4[/tex]
-Solve the expression:
[tex]g(5) = (5)^{2} - 4[/tex]

A family daycare center charges a $75 enrollment fee and $100 per week for a child to attend. Write the linear equation to model this situation.
Answer:
100x+75=y
Step-by-step explanation:
Answer:
y=100x+75. Where y equals total cost and x equals numbers of weeks enrolled.
Step-by-step explanation:
75 is the upfront cost, aka the cost of zero weeks, this cost will never change and is a one-time payment, therefore it needs no variable. 100 is the cost per week which means every week costs 100 more dollars, this is why it must have a variable because it will change with time. They are added together because they both show the total cost and together will show how much one person is spending.

A cookie contains 9 grams of fat. If you eat no fewer than 4 and no more than 7 cookies, how many grams of fat will you
consume?
compound inequality
Step-by-step explanation:
Since each cookie has 9 grams of fat, four cookies would contain 4*9 = 36 grams of fat.
Also nine cookies has 7*9 = 63 grams of fat.
So the number of grams consumed will be at least 36 and no more than 63.
The number of grams consumed will be; at least 36 and no more than 63.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We have been given that cookie contains 9 grams of fat and eat no fewer than 4 and no more than 7 cookies, then;
Since each cookie has 9 grams of fat, four cookies would be;
4 x 9 = 36 grams of fat.
Also, the nine cookies have 7 x 9 = 63 grams of fat.
Therefore, the number of grams consumed will be; at least 36 and no more than 63.

What is a Ratio?A ratio shows us the number of times a number contains another number.
Since For every 5 hardcover books a teacher buys, he or she can get 2 paperback books for free. Therefore, the ratio of hardcover books to paperback books will be,
Hardcover/paperback = 5/2
Using the same ratio for 35 hardcover books,
35/Paperbook = 5/2
(35×2)/5 =Paperbook
Paperbook = 14

For Judy's birthday, her friends gave her a gift card. She went to the clothing store and bought a total of $178.25 worth of clothing. Judy used all of the money on the gift card to pay for part of the total. She paid the remaining $71.30 with cash. Which percentage best describes the part of the total Judy paid for with the gift card?
Answer:
60%
Step-by-step explanation:
Firstly, we want to solve for the amount on the gift card
the total cost is $178.25
the cash payment is $71.30
then the value of the gift card is
=$178.25- $71.30
=$106.95
Therefore the percentage of the gift card to the total pay is
=(106.95/178.25)*100
=0.6*100
=60%

How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
WE are given that AB is rotated 120° clockwise about B.
AB is rotated 120° clockwise about B. Then AB is rotated 45° counterclockwise about A.
It is rotated 120° clockwise and clockwise is negative and the other is rotated 45° counterclockwise and counterclockwise is positive.
