Answer: A'(3,2), B'(0,1) and C'(-4, -5).
Step-by-step explanation:
When we rotate (a,b) 90 degrees clockwise, the new point will be (b,-a).
i.e. rotation rule for 90 degrees clockwise : (x,y) → (y,-x)
Given: Triangle ABC with coordinate points A(-2,3); B(-1,0); C(5,-4) is rotated 90 degrees clockwise.
Then, the new image points for triangle A'B'C' will be :
A(-2,3) → A'(3,-(-2)) =A'(3,2)
B(-1,0)→ B'(0,-(-1)) = B'(0,1)
C(5,-4) → C'(-4, -5)
Hence, the new image points for triangle A'B'C' are A'(3,2), B'(0,1) and C'(-4, -5).

What is the y-intercept of a line with a slope of 2/3 that passes through (-5,1)?
Answer:
(0,13/3)
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b
We know the slope is 2/3 and a point on the line is (-5,1)
y = 2/3x +b
Substitute the point into the equation
1 = 2/3 (-5) +b
1 = -10/3 +b
3/3 = -10/3 +b
Add 10/3 to each side
10/3 = b
The equation is
y = 2/3 x+13/3
The y intercept is
(0,13/3)
Answer:
[tex](0,13/3)[/tex]
Step-by-step explanation:
Since we know the slope and a point, we can use the point-slope form.
Recall that the point-slope form is:
[tex]y-y_1=m(x-x_1)[/tex]
Let m be 2/3 and let (-5,1) be x₁ and y₁. Therefore:
[tex]y-(1)=\frac{2}{3}(x-(-5))[/tex]
Simplify:
[tex]y-(1)=\frac{2}{3}(x+5)[/tex]
Distribute:
[tex]y-1=\frac{2}{3} x+\frac{10}{3}[/tex]
Add 1 to both sides. The left cancels. 1 is the same as 3/3:
[tex]y=\frac{2}{3} x+\frac{10}{3}+\frac{3}{3}\\[/tex]
Simplify:
[tex]y=\frac{2}{3}x+\frac{13}{3}[/tex]
This is in slope-intercept form. The coefficient is the slope and the y-intercept is the constant. Thus, the y-intercept is 13/3.

En un entrenamiento, Mariana metió 12 de los 15 tiros al arco que pateo. Carla tuvo una efectividad del 75%. Cual de las dos chicas tuvo un mejor desempeño al pasear al arco?
Answer:
Mariana has better performance.
Step-by-step explanation:
We are given that in a training session, Mariana made 12 of the 15 shots on goal that she kicked and Carla had an effectiveness of 75%.
And we have to find which girl's performance is better.
Since it is stated that Carla had an effectiveness of 75%.
Similarly, we will find the effectiveness of Mariana;
Total shots available to Mariana = 15 shots
Number of shots on goal = 12
So, her effectiveness = [tex]\frac{12}{15} \times 100[/tex]
= [tex]4 \times 20[/tex] = 80%
This shows that Mariana has a better performance as compared to Carla as 80% > 75%.

Alonzo is planning to purchase roses for his mother on her birthday. He has seen them advertised at 12 roses for $15.00 and 20 roses for $23.00. Which is the better buy?Explain and show work below.
Answer:
20 roses at $23 is the better buy
Step-by-step explanation:
Here, we have Alonzo who wants to purchase Roses. He has two buying options.
Either he buys 12 roses at $15 or buys 20 roses at $23. We want to know which of the two options is better for him.
what we shall do here is to get the unit price per each of the roses in each set. The set having the lower rose to dollar value is the better buy.
Firstly, 12 roses for $15.
Price per rose here is 15/12 = $1.25 per rose
For 20 roses at $23
Price per rose here is 23/20 = $1.15 per rose
Since 1.15 is less than 1.25, then the second option is the better buy.

. Dillion deposits $150 into his account. One week later, he withdraws $26. Write an addition expression to represent this situation. How much higher or lower is the amount in his account after these two transactions?
Answer:
[tex]Expression = x + 150 +(- 26)[/tex]
$124 higher
Step-by-step explanation:
Given
[tex]Deposit = \$150[/tex]
[tex]Withdrawal = \$26[/tex]
Required
Represent the situation
Determine how much higher or lower is the remaining amount
Let the initial amount in his account be represented with x
When he deposited, the balance becomes
[tex]Balance = x + 150[/tex]
When he withdrew, the balance becomes
[tex]Balance = x + 150 + (-26)[/tex]
Hence, the algebraic expression is
[tex]Expression = x + 150 +(- 26)[/tex]
Calculating how much higher or lower
[tex]Balance = x + 150 + (-26)[/tex]
Open bracket
[tex]Balance = x + 150 -26[/tex]
[tex]Balance = x + 124[/tex]
Recall that the initial amount in the account is x
The difference between the balance and the x is as follows
[tex]Difference = x + 124 - x[/tex]
[tex]Difference = \$124[/tex]
Hence, the account has a higher of $124 after both transactions

The middle note C has a frequency of 262 hertz and can be modeled using a sine function with an amplitude of 1.5, where x is time in seconds. Which function represents the vibrations of this note?
Answer: f(x) = 1.5*sin(x*2*pi/0.0038s)
Step-by-step explanation:
A sine function is:
f(x) = A*sin(c*x + f)
Where A is the amplitude, we know that it is 1.5
c is a constant that depends on the frequency.
f is a phase.
As there is no mention of a phase, we can assume f = 0.
Then our function is:
f(x) = 1.5*sin(c*x)
now let's find the value of c.
We know that the frequency is 262hz.
Then the period can be calculated with the equation:
T = 1/f.
T = 1/262 Hz = 0.0038 seconds.
Now, the period of a sin function is 2*pi.
whit pi = 3.14159265358979.....
Then we have that:
sin(0) = sin(c*0.0038s)
sin(0) = sin(2*pi)
then:
c*0.0038s = 2*pi
c = 2*pi/0.0038s
Then the function is:
f(x) = 1.5*sin(x* 2*pi/0.0038s)
According to the information given, the sine function is:
[tex]y = 1.5\sin{(524\pi x)}[/tex]
The standard sine function is given by:
[tex]y = A\sin{(2\pi fx)}[/tex]
In which:
A is the amplitude.f is the frequency, in Hz.In this problem:
Amplitude of 1.5, hence [tex]A = 1.5[/tex]Frequency of 262 Hz, hence [tex]f = 262[/tex]Then, the equation is:
[tex]y = A\sin{(2\pi fx)}[/tex]
[tex]y = 1.5\sin{(2\pi (262)x)}[/tex]
[tex]y = 1.5\sin{(524\pi x)}[/tex]

Answer:
Solution : Option A and Option C
Step-by-step explanation:
To determine our vertical asymptote here we can make the denominator of the rational function equivalent to zero ...
x - 9 = 0,
x = 9 - this is our vertical asymptote
Now there are three rules that we need to apply when determining the horizontal asymptote. To do so we take the degree of each " x " term and compare the numerator and denominator degree.
If the numerator (degree) < denominator (degree), we take the degree of the numerator as the asymptote --- (1). If the numerator (degree) = denominator (degree) we take the coefficient of the x terms, and divide --- (2). If the numerator (degree) > denominator (degree) their will be no asymptote.
In this case our degree for the numerator is 1, (x¹) and our degree for the denominator is the same, 1 (x¹). Therefore we divide the coefficients, 2 / 1 = 2. Our horizontal asymptote is y = 2.

Do only equations with variables on both sides ever have no solution or can an equation with the variable on one side have no solution? Justify your answer.
Answer:
When an equation that has no solution, it means that the equation does not have an answer and that there is no way that the equation will be true regardless of the values given to variables or where the variables are on one side or both sides of the equation because of the way the equation was set up or constructed.
Step-by-step explanation:
For example, the following equation with variables on both sides of the equal sign that has no solution, we have;
21 + 9·x = 15+ 5·x + 4·x
21 + 9·x = 15+ 9·x
Subtracting 9·x from both sides gives;
21 + 9·x - 9·x = 15+ 9·x - 9·x
21 + 0 = 1 5 + 0
21 = 15 (Which not true and cannot be true because 21 ≠ 15)
For example of equation with variables on one side of the equal sign has no solution, we have;
21 + 9·x - 5·x - 4·x = 15
21 + 9·x - 9·x = 15
21 + 0 = 15
21 = 15 (Which not true and cannot be true because 21 ≠ 15).
Answer:
they don't always have solutions
