I just need to know
1. slope
2. y-intercept
3. slope intercept form
(-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-interceptTherefore slope intercept form of h(x):
h(x) = -¹/₄x + ³/₄WHAT ARE THE COORDINATES OF POINT Q? (-4,2 1/2)

Answer:
6b
Step-by-step explanation:
Using the distance formula that is given, and knowing that we are trying to get from C to B, we have y₂ = b and y₁ = -5b, so y₂ - y₁ = b-(-5b) = 6b

What are the next three terms in the sequence 4096, 1024, 256, 64, ...?
Answer:
16,4, and 1
Step-by-step explanation:
You divide by 4
4096 divided by 4 gives 1024
1024 divided by 4 gives 256
256 divided by 4 gives 64
So
64 divided by 4 gives 16
16 divided by 4 gives 4
4 divided by 4 gives 1

Calculate the distance between the points N=(-9,9) and H=(-3,2) in the coordinate plane.
Answer:
[tex]\sqrt{85}[/tex] units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = N(- 9, 9) and (x₂, y₂ ) = H(- 3, 2)
d = [tex]\sqrt{-3+9)^2+(2-9)^2}[/tex]
= [tex]\sqrt{6^2+(-7)^2}[/tex]
= [tex]\sqrt{36+49}[/tex]
= [tex]\sqrt{85}[/tex]

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.
so
3x° = 120°
Divide both sides by 3
3x/3 = 120 / 3
x = 40
Therefore, the value of x = 40.
What are the vertices of triangle A'B'C' produced by (x, y) -> (x+5, y-2)?
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)Answer my last question

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

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

A chemist is using 353 milliliters of a solution of acid and water. If 14.7 of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth
Answer:
The amount of Acid in a solution = 51.9 millimeters
Step-by-step explanation:
Given that the total amount of solution of acid and water = 353 milliliters
Acid percentage = 14.7%
Thus, in order to determine the amount of acid, all we need is to multiply 353 with 14.7% or 0.147.i.e
Amount of Acid = 14.7% of 353
= 0.147 × 353
= 51.9 millimeters
Therefore, the amount of Acid in a solution = 51.9 millimeters
The function c(x) = 18x -10 represents the cost in dollars. How many tickets can you buy?
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 = ticketsAssuming 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

hours on Thursday. Did she study for at least 15 hours? Explain.
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".
