Step-by-step explanation:
In order to figure out what is f(-2), we substitute all the "x" in the function with "-2" like this:
f(-2) = x² - 6x - 14 = (-2)² - 6(-2) -14
Now we can follow PEMDAS:
(-2)² - 6(-2) -14
= 4 + 12 - 14
= 2.
Hence, f(-2) = 2.
Pine Hill Middle School has 300 students. In
Zoey's class, two out of five students belong to
a club. Use this ratio to predict how many
students in the school belong to a club.
There are 120 students in the school Pine Hill Middle School who belong to a club.
What is a ratio?A ratio describes a comparison between two or more quantities in simplest form.
Given that Pine Hill Middle School has 300 students.
Also given two out of five students belong to a club.
∴ We can conclude that (2/5)th of the total students belong to the club which is numerically,
= (2/5)×300.
= 120 students.
We can also solve this by ratios if in a total of 5 students 2 students belong to a club that means 3 students doesn't belong to the club and their ratio is 2:3.
∴ The no. of students belonging to the club is 2/(2+3)×300.
= (2/5)×300.
= 120 students belong to the club.

This week, 300 tickets were sold to the school play. This is 120 percent of the number of tickets sold last week. How many tickets were sold last week for the school play?
Answer:
300=120/100* number of tickets sold last week.
So last week's number of tickets=300÷(120/100)=300*100/120=30*100/12=5*100/2=5*50=250 tickets
So the answer is 250

The number of fish in a lake decreased by 25% between last year and this year. Last year there were 60 fish in the lake. What is the population this year? (Consider using a tape diagram)
Answer: This population, the population is 45 fish.
Step-by-step explanation: This problem can be solved by a rule of three. Last year there were 60 fish in the lake. That was 100, that is, decimal 1. This year it decreased by 25%. So there 100%-25% = 75%, that is decimal 0.75. So 60 fish - 1 x fish - 0.75. This population, the population is 45 fish.

Mr. Parker wants to rent a cargo van for a day. It will cost the daily fee of $50.00 plus $0.35 per mile driven.
Let m = the number of miles Mr. Parker drives for the day. Write an algebraic expression that shows the amount he will pay for the van.
Answer:
50d * 0.35m
Step-by-step explanation:
so I don't normally do it like this it would normally be 50 * 0.35x. but the days also had a fee unless she doesn't have it for 2 days and only has it one but d is the days she has it and m is the miles driven the * is times
you would have to find out the days she has it unless you don't have that is would be the answer above (if I am wrong I'm sorry)
A bowling alley charges a rental fee of $12 for the lane. They then charge $7.75 for each game bowled. If I have a total of $105. Write an inequality and solve it to find the maximum number of games, g, that I could play?
Answer:
12
Step-by-step explanation:
12 + 7.75*g <= 105 Subtract 12
7.75g < =105 - 12 divide by 7.75
g <= 93 / 7.75
g < = 12
You have to put an equal sign in there because 7.75 divides equally into 93.
A 9 foot flagpole cast a shadow 6 feet long, and at the same time a nearby tree cast a shadow 14 feet long. What is x the hight of the tree.
The height of the nearby tree is 21 feet.
What is proportion?
Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole.
According to the problem,
Height of the flagpole = 9 feet
Length of the shadow = 6 feet
Length of the shadow cast by the tree = 14 feet
Let the height of the tree be x,
Since they cast aa shadow at the same time nearby, If we set up a proportion,
⇒ [tex]\frac{9}{6}[/tex] = [tex]\frac{x}{14}[/tex]
⇒ 6x = 126
⇒ x = [tex]\frac{126}{6}[/tex]
⇒ x = 21 feet
Hence, we can conclude, the height of the shadow is 21 feet.
