What is the slope of the line that contains the points (1, −1) and (−2, 8)?
A. −3
B. 7 over 3 negative
C. 1 over 3 negative
Problem 1
Plug in x = 0 and solve for y to get the y intercept
6x+12y = 60
6(0)+12y = 60
12y = 60
12y/12 = 60/12 ... divide both sides by 12
y = 5
Answer: A) 5
======================================
Problem 2
Use the slope formula.
The two points are (x,1, y1) = (1, -1) and (x2, y2) = (-2, 8)
m = (y2-y1)/(x2-x1)
m = (8-(-1))/(-2-1)
m = (8+1)/(-2-1)
m = 9/(-3)
m = -3
Answer: A) -3
A function is shown.
f(x)=x2+2x−1
Which graph represents the function?
The fourth graph represents the function.
We have to rewrite the given function into the standard form of a parabola.
What is a parabola?A parabola is a U-shaped plane curve that is symmetrical about its vertex.
What is the standard form of a parabola?The standard form of a parabola is given by:
y = (x-h)²+k
Where (h,k) is the vertex of the parabola.
The given function is rewritten in its standard form:f(x) = x²+2x-1
We can rewrite this as:
f(x) = x²+2x+1-2
f(x) =( x+1)²-2
By observing the function in standard form, we can see that the vertex of the parabola is (-1,-2).Now compare this with the given graphs. The only graph that has its vertex at (-1,-2) is the fourth graph.
We have found the graph that represents the function f(x) = x²+2x-1 to be the fourth graph.

Find the perimeter of the polygon with the vertices q(−3, 2), r(1, 2), s(1,−2), and t(−3,−2).
The solution is in the attached picture.
*******************The perimeter of a shape is the sum of all visible side lengths of the shape. The perimeter of polygon qrst is 16 units.
Given that:
[tex]q = (-3,2)[/tex]
[tex]r = (1,2)[/tex]
[tex]s = (1,-2)[/tex]
[tex]t = (-3,-2)[/tex]
First, we calculate the distance between the vertices using distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
So, we have:
[tex]qr = \sqrt{(-3- 1)^2 + (2 - 2)^2} = \sqrt{16} = 4[/tex]
[tex]rs = \sqrt{(1- 1)^2 + (2 - -2)^2} = \sqrt{16} = 4[/tex]
[tex]st = \sqrt{(1--3)^2 + (-2 - -2)^2} = \sqrt{16} = 4[/tex]
[tex]tq = \sqrt{(-3--3)^2 + (-2 -2)^2} = \sqrt{16} = 4[/tex]
The perimeter (P) is the sum of all sides:
[tex]P = qr + rs + st + tq[/tex]
[tex]P = 4 + 4 + 4 + 4[/tex]
[tex]P = 16[/tex]
Hence, the perimeter is 16 units.

ANSWER
Yes it is very true
EXPLANATION
If the two equations intersect at [tex](50,60)[/tex] then this point must satisfy the two equations.
[tex]3x+2y=270---(1)[/tex]
We substitute [tex](50,60)[/tex] in to erquation (1)
[tex]3(50)+2(60)=270[/tex]
[tex]150+120=270[/tex]
[tex]270=270[/tex]
[tex]y=\frac{4}{5}x+20 ---(2)[/tex]
We now substitute [tex](50,60)[/tex] in to erquation (2) also
[tex]60=\frac{4}{5}(50)+20[/tex]
[tex]60=40+20[/tex]
[tex]60=60[/tex]
Since the point satisfy all the two equations, it is true that they intersect at [tex](60,50)[/tex]

There were 13,501 visitors to a museum in june.What is this number rounded to nearest ten thousand ?Explain how
13,501 rounded to the nearest ten thousand is 14,000. This is because if you look at the 3, the number next to it is 5, causing it to round up. Numbers 0-4 are rounded down, and numbers 5-9 are rounded up.
Answer:
10,000
Step-by-step explanation:
When we round a number to the nearest ten thousand we check the digit at the thousand place,
If the digit ≥ 5,
The number is rounded to next ten thousand,
If the digit < 5,
The number is rounded to previous ten thousand.
Here, the given number,
13,501,
Digit at thousand place = 3 ( < 5 )
Thus, 13,501 ≈ 10,000 ( nearest ten thousand )

Is it possible for a number to be a rational number that is not an interger but is a whole number. Explain
Whole numbers are a subset of integers, which in turn are a subset of rational numbers.
So, every whole number is an integer, and every integer is a rational number.
So, it is possible for a rational number not to be an integer. Think of any decimal number: 1.356 is a rational number, but it's not an integer.
On the other hand, if a number is not an integer, it can't be a whole number, because all whole numbers are integers.

Jasmine is a receptionist at a doctors office . She books 36 appointments each day. Four out of every 24 appointments are cancelled. How many appointments are cancelled each day?
Answer:
6 appointments are cancelled per day
Step-by-step explanation:
Question says 4 out of 24 appointments are cancelled.
It means out of 1 appointment , the cancelled appointments = [tex]\frac{4}{24}[/tex]
=[tex]\frac{1}{6}[/tex]
Now the questions says each day there are 36 appointments
And we have to find how many appointments got cancelled each day,
It means we have to find how many appointments got cancelled out of 36 appointments each day
So we multiply 36 by [tex]\frac{1}{6}[/tex]
=[tex]36 * \frac{1}{6}[/tex]
= 6
Hence , 6 appointments got cancelled each day.
Jasmine has 6 appointments cancelled per day, determined by scaling the given cancellation ratio (4 out of every 24) to match the number of daily appointments she books (36).
Explanation:To answer this question, we first need to understand the rate at which appointments are cancelled. The problem states that 4 out of every 24 appointments are cancelled. To find out how many appointments are cancelled each day, we use this ratio and apply it to the 36 appointments that Jasmine books each day.
First, we need to scale the ratio to match Jasmine's daily bookings. To do this, we multiply the numerator and denominator of the ratio by 36/24, which is 1.5. This gives us a new ratio of 6 cancellations for every 36 appointments.
So, each day, out of the 36 appointments that Jasmine books, 6 appointments are cancelled.

Given:
m 2 = 30°, m P =
30
60
90
120
Answer:
Measure of ∠P = 60°
Step-by-step explanation:
Consider triangle PMO.
Since PM is perpendicular to MO , hence m∠PMO = 90°
Also given that m∠MOP = m∠2 = 30°
And since sum of three angles of a triangle is 180°
⇒ m∠PMO + m∠MOP + m∠MPO = 180°
⇒m∠MPO = 180° - (m∠PMO + m∠MOP) = 180° - ( 90 + 30 ) = 60°
Hence m∠MPO that is m∠P is 60°
Answer:
m 2 = 30°, m P = 60
The correct choice is 60
