Which equation describes the line with slope of 3 and
containing the point (-3,-2)?
y = -1/3x-3
y = 1/3x - 1
y = 3x – 2
y = 3x + 7
Option D is the correct answer, y = 3x + 7
The line is y=3x+7
Given that the point is (-3, -2) and slope=m=3.
Using the point slope formula we get:
[tex]y-\left(-2\right)=3\left(x-\left(-3\right)\right)\\y+2=3\left(x+3\right)\\y+2=3x+9\\y=3x+7[/tex]
The line is y=3x+7

Writé the equation for a parabola with x-intercepts of 1 and -3 and passes through
(-9,28).
Answer:
[tex]\displaystyle f(x)=\frac{7}{15}(x-1)(x+3)[/tex]
Step-by-step explanation:
Equation of the Parabola
The general form of the equation of the parabola is:
[tex]f(x)=ax^2+bx+c[/tex]
We can try to find the values of a,b, and c by using the three given points (1,0),(-3,0),(-9,28).
However, we'll use an easier method. There is another form of the parabola in case we know its roots, also called zeros or x-intercepts. If p and q are the roots of f, then f can be expressed as:
[tex]f(x)=a(x-p)(x-q)[/tex]
We already know the values of p=1 and q=-3, thus replacing them into the equation, we have:
[tex]f(x)=a(x-1)(x+3)[/tex]
We only need to find the value of a. We do that by using the point (-9,28):
[tex]28=a(-9-1)(-9+3)[/tex]
Operating:
[tex]28=a(-10)(-6)=60a[/tex]
Solving for a:
[tex]\displaystyle a=\frac{28}{60}=\frac{7}{15}[/tex]
Thus, the equation of the parabola is:
[tex]\boxed{\displaystyle f(x)=\frac{7}{15}(x-1)(x+3)}[/tex]
How would you explain to someone the rules of a horizontal translation where we are subtracting from the inputs(within the parenthesis) before evaluating the function
Answer:
Ok, we know that we can write a horizontal translation as:
y' = f(x - A)
where if A is positive, this moves the graph of f(x) A units to the right.
Why is this?
Ok, let's compare:
y = f(x)
and
y' = f(x - A)
in y, when x = 0 we have f(0).
While to have this same point in y', we need to evaluate in x = A.
f(A - A) = f(0).
Then the value f(0) is now at x = A, this means that the point moved A units to the right.
And you can do this for all the values, so you will find that the entire graph of f(x) has ben moved A units to the right.

The Lanier band is raising money for their annual trip. They are selling insulated cups for $25 each and have already made $1500. They need to make at least $10,000 to go on the trip. Which inequality represents the situation?
A. 25x + 1500 ≤ 10,000
B. 25x+ 10,000 ≤ 1500
C. 25x + 1500 ≥ 10,000
D. 25x + 10,000 ≥ 1500
Answer:
25x + 1500 < 10,000
They have to make at least $10,000 to go on the trip.
The cups are $25 each, so it would be 25x.
In addition to that, $1500 has already been made.
= 25x + 1500 < 10,000

Rhone purchases eggs from a local dairy farm. He finds 3 broken eggs. He uses half the remaining eggs to bake a few pancakes. If 5 eggs remain now, how many eggs did Rhone purchase from the farm?
Answer:
He bought 13 eggs
Step-by-step explanation:
Lets make a equation:
X-3 /2=5
That means 5 times 2+3 would be X. 5 times 2=10 plus 3=13
The required number of eggs that Rhone purchased is given as 13.
Given that, Rhone purchases eggs from a local dairy farm. He finds 3 broken eggs. He uses half the remaining eggs to bake a few pancakes, at the end, 5 eggs remain now, how many eggs did Rhone purchase from the farm is to be determined.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let the number of eggs be x,
Now,
3 eggs were found broken, the remaining eggs = x - 3,
He uses half the remaining eggs to bake a few pancakes and 5 eggs were left,
So,
X-3 /2=5
x = 10 + 3
x = 13
Thus, the required number of eggs that Rhone purchased is given as 13.

A spinner is divided into 5 uneven sections, which are labeled red, blue, green, yellow, and orange. Ricardo spun the spinner 120 times. The results are Red: 35 Blue: 36 Green: 32 Yellow: 8 Orange: 9 Based on the different data, what is the probability ricardo will soon blue on his next spin?
Answer: 3/10
Step-by-step explanation: It's 3/10 because the total amount when you add all the numbers together is 120, and since he spins it 120 times, we could assume that 36 would be the amount of times that it would land on it based on the data given. We're not done yet though. You do 36/120 to get the probability, and you simplify it to get 3/10.
The probability that Ricardo spins blue on his next spin is 0.3
We could use the principle of experimental probability to determine the probability of spinning blue on next spin :
Given that :
Red: 35
Blue: 36
Green: 32
Yellow: 8
Orange: 9
Experimental probability = (number of times event occur / total number of trials)
Total number of trials = (35 + 36 + 32 + 8 + 9) = 120
The experimental probability of spinning blue is thus :
(Number of blue spins / total number of spins)
= 36 / 120
= 0.3
The probability of spinning blue on next spin is 0.3

Is this a function or non function?
Answer:
yes it is a function
Step-by-step explanation:
A function can only cross the y-axis once. If it crosses any y-axis more than once, it is not a function. This starts at 0 and will continue on to positive infinity. It will never cross the same y-axis twice. So yes, it is a function.

On a coordinate plane, a straight red line with a positive slope, labeled g of x, crosses the x-axis at (negative 3, 0) and the y-axis at (0, 3). A straight blue line with a positive slope, labeled f of x, crosses the y-axis at (0, negative 3) and the x-axis at (1, 0). Both lines intersect at (3, 6).
Which statement is true regarding the functions on the graph?
f(6) = g(3)
f(3) = g(3)
f(3) = g(6)
f(6) = g(6)
Answer:
f(3)=g(6)
Step-by-step explanation:
The statement is true regarding the functions on the graph is f of 3=g of 3. The correct option is B.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given two function f(x) and g(x) which intersect at (3, 6).
Now, when two functions intersect then it means that there is a value of x for which the value of both the functions is equal. This value of x and y is the point at which the two functions intersect.
Hence, the statement is true regarding the functions on the graph being
f of 3=g of 3.

The area of the base of a square notepad is 2.25 square inches. What is the length of one side of the base of the notepad?
Answer:
1.5 inches
Step-by-step explanation:
Because the base of the notepad is a square, that means that each side of the base would be equal. Since the area is 2.25 square inches, and each side would have to be equal, the equation to solve would be x*x = 2.25, or x^2=2.25. So, you just take the square root of both sides, and x=1.5 inches. Each side of the notepad would be 1.5 inches.
Answer: 1.5 inches

Answer:
Yes, the price the school pays each year in entrance fees is proportional to the number of students entering the zoo
Step-by-step explanation:
Relationships between two variables is proportional if their ratios are equivalent.
In 2010, the school paid $1,260 for 84 students to enter the zoo.
Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1260:84=15:1[/tex]
In 2011, the school paid $1,050 for 70 students to enter the zoo.
Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1050:70=15:1[/tex]
In 2012, the school paid $1,395 for 93 students to enter the zoo.
Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1,395:93=15:1[/tex]
As [tex]1260:84=1260:84=1,395:93=15:1[/tex],
the price the school pays each year in entrance fees is proportional to the number of students entering the zoo.
