What are the vertices of triangle A'B'C' produced by (x, y) -> (x+5, y-2)?

Answers

Answer:

The vertices of triangle A'B'C' produced by (x, y) → (x+5, y-2) will be:

A'(8, -2) B'(8, 0) C'(5, -5)

Step-by-step explanation:

Given the vertices of an original triangle ΔABC such that

A = (3, 0)B = (3, 2)C = (0, -3)

As the rule of translation is given by

Translation: (x, y) → (x+5, y-2)

So, after the translation the vertices of the original triangle ΔABC will be translated as:

A = (3, 0) → (x+5, y-2) ⇒ (3+5, 0-2) = A'(8, -2)

B = (3, 2) → (x+5, y-2) ⇒ (3+5, 2-2) = B'(8, 0)

C = (0, -3) → (x+5, y-2) ⇒ (0+5, -3-2) = C'(5, -5)

Therefore, the vertices of triangle A'B'C' produced by (x, y) → (x+5, y-2) will be:

A'(8, -2) B'(8, 0) C'(5, -5)

What is the solution to the following equation? x2 + 3x + 4 = 0

Answers

Answer:

[tex]x=\dfrac{-3\pm \sqrt7i}{2}[/tex]

Step-by-step explanation:

The given equation is [tex]x^{2}+3x+4=0[/tex].

We need to find the solution of the above equation.

The solution of an equation [tex]ax^2+bx+c=0[/tex] is :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

We have, a = 1, b = 3 and c = 4

[tex]x=\dfrac{-3+ \sqrt{(3)^2-4(1)(4)} }{2}, \dfrac{-3- \sqrt{(3)^2-4(1)(4)} }{2}\\\\=\dfrac{-3+\sqrt{9-16}}{2}, \dfrac{-3-\sqrt{9-16}}{2}\\\\=\dfrac{-3\pm \sqrt7i}{2}[/tex]

So, the solution of the given equation is [tex]\dfrac{-3\pm \sqrt7i}{2}[/tex].

Answer my last question

Answers

Answer:

I answer your last question just now, yep right now this momment

Step-by-step explanation:

The function c(x) = 18x -10 represents the cost in dollars. How many tickets can you buy?

Answers

Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.

So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 80 dollars.

The solution would still clear your concept though.

Answer:

Please check the explanation.

Step-by-step explanation:

We know that the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where m is the slope or rate of change and b is the y-intercept

Given the function

[tex]c(x) = 18x -10[/tex]

comparing with the slope-intercept form of the line equation

here

rate of change = 18c(x) = y = the costx = tickets

Assuming the total cost i.e. c(x) = $80

In order to find the value of x, set [tex]c(x) = 80[/tex]

i.e.

[tex]80 = 18x -10[/tex]

switch sides

[tex]18x - 10 = 80[/tex]

add 10 to both sides

[tex]18x - 10 + 10 = 80 + 10[/tex]

[tex]18x = 90[/tex]

Divide 18 to both sides

[tex]\frac{18x}{18}=\:\frac{90}{18}[/tex]

[tex]x = 5[/tex]

Therefore, we conclude that if you can buy x = 5 if you pay 90 dollars.

Tammy figured her math exam would be difficult unless she put in at
least 15 hours of study time to prepare. She studied 2½ hours on
Monday, 3 hours on Tuesday, 4¾ hours on Wednesday, and 4 ½
hours on Thursday. Did she study for at least 15 hours? Explain.

Answers

Answer: No, she did not study for at least 15 hours.

=======================================================

Explanation:

Fractions are often a pain, so I find it easier to convert to decimal form whenever possible.

1/2 = 0.5

3/4 = 0.75

which lead to,

2 & 1/2 = 2 + 1/2 = 2 + 0.5 = 2.5

4 & 3/4 = 4 + 3/4 = 4 + 0.75 = 4.75

4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

-----------------------------

We can then rephrase the problem like so:

"She studied 2.5 hours on Monday, 3 hours on Tuesday, 4.75 hours on Wednesday, and 4.5 hours on Thursday"

Add up those decimal values to get:

2.5 + 3 + 4.75 + 4.5 = 14.75

In total, Tammy studied for 14.75 hours, which is equivalent to 14 & 3/4 hours.

This result is smaller than 15, so she did not study for at least 15 hours.

Note: "at least 15" is the same as saying "15 or more".

Answers

Answer:

The value of x = 40.

Step-by-step explanation:

From the figure, it is clear that given a transversal line cuts two parallel lines m and n, thus making the corresponding congruent angles 120° and 3x°.

Here, 120° is corresponding to 3x°.

As corresponding angles are congruent.

3x° = 120°

Divide both sides by 3

3x/3 = 120 / 3

x = 40

Therefore, the value of x = 40.

What is the probability that a number selected at random integers 3 to 30 inclusive is a multiple of 3

Answers

Answer:

5/14 if I'm not wrong!

I hope it will be useful.

The probability that a number selected at random in between integers from 3 to 30 inclusive is a multiple of 3 is .

What is probability?

The term probability indicates the chance of happening an event or incident.

The total integers between 3 to 30 inclusive is a multiple of 3 is:

{3, 6, 9, 12, 15, 18, 21, 24, 27, 30}

Therefore, favorable event = 10 numbers.

Here, sample space is:

{3, 4, 5, 6,......, 30} = 28 numbers

Therefore, required probability is

= (10 / 28)

= 5 / 14

Answers

(-5, 2) ⇒ x₁ = -5, y₁ = 2

(7, -1) ⇒ x₂ = 7, y₂ = -1

Slope:

[tex]\bold{m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-2}{7+5}=\dfrac{-3}{12}=-\dfrac14}[/tex]

Slope intercept form:

y = mx + b

Plug m and (7, -1) :

-1 = -¹/₄(7) + b

-1 + ⁷/₄ = b

b = ³/₄ ← y-intercept

Therefore slope intercept form of h(x):

h(x) = -¹/₄x + ³/₄
