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

Mimi sells super-sized cookies for $1.50 each and estimates she has expenses of $10 to make one batch of cookies. If the inequality 1.5x - 10 > y models this situation, how many cookies, x, would she need to sell to make a profit of at least $30? a: x > 20 cookies b: x > 26 cookies c: x > 27 cookies d: x > 35 cookies
Answer:
(b) x > 26 cookies
Step-by-step explanation:
The selling price of 1 super-sized cookie, S.P.=$1.50
Let a batch have x cookies.
So, the selling price of x cookies=1.5x
The expences in making one batch of cookies=$10
So, net profit = 1.5x-10
The given inequality to model this is 1.5x - 10 > y, That means the profit for one batch is greater than y.
As she wants to make a profit of at least $30, so for this condition, the value of y is 30.
Now, the given inequality become,
[tex]1.5x - 10 >30[/tex]
[tex]\Rightarrow 1.5x>30+10[/tex]
[tex]\Rightarrow x>\frac{40}{1.5}[/tex]
[tex]\Rightarrow x>26\frac{2}{3}[/tex]
As x is the number of cookies, so, it can't have a fractional value. This can be written as
[tex]x>26[/tex] or [tex]x\geq27.[/tex]
So, she has to sell more than 26 cookies to make a profit of at least $30.
Hence, option (b) is correct.
Toby the Tiger makes $25 an hour selling cereal. Write an equation to
describe the proportional relationship between the amount of hours that
Toby works and the amount of money that Tony earns. (Hint: Make Table)
*
y=5x
y=15x
y=35x
y=25x
Answer:
I think it is y=25x
Step-by-step explanation:
Since Tony the Tiger makes $25 an hour, in 2 hours, he would make $50. Both of them, when divided, equal 25, the constant of proportionality.
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]

explain how to graph an equation in slope-intercept form.
Answer: explain how to graph an equation in slope-intercept form.
Step-by-step explanation: To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

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.

Answer:
y +4 = 1/5(x +5)
Step-by-step explanation:
The equation of a line with slope m through point (h, k) in point-slope form is ...
y -k = m(x -h)
You have m=1/5, (h, k) = (-5, -4). Putting these values into the formula gives ...
y -(-4) = (1/5)(x -(-5))
y +4 = 1/5(x +5)
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

What is the 'K' (Constant of Proportionality) for a straight line that goes through the origin with a point of (3, 30).
Answer:
k = 10
Step-by-step explanation:
The constant of proportionality of a graph in Mathematics is simply the ratio of y to x which can be called the slope.
It's given by; k = y/x
We are given; y = 30 and x = 3.
Thus;
k = 30/3
k = 10
Each year the seventh graders who study life science participate in a special field trip to the city zoo in 2010 the school paid $1,260 for 84 students to enter the zoo in 2011 the school paid $1,050 for 70 students to enter the zoo in 2012 the school paid $1,395 for 93 students to enter the zoo is the price the school pays each year in entrance fees proportional to the number of students entering the zoo explain why or why not
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.
Answer:
yes
Step-by-step explanation:
the price the school pays each year in entrance fees is proportional to the number of students entering the zoo.
