The slope of the line segment AB will change from -3 to 1/3 after a 270 degree rotation of the line segment
How to determine the slope of line segment A'B'information gotten from the question include
Points A' and B' are the images of points A and B after a 270 rotation
the slope of line segment AB is -3
Rotation is one of the movements that is under transformation it involves a movement about an axis.
With respect to the problem here, the axis of the rotation is the origin of the coordinates
The rotation will lead to formation of an image A'B' which is perpendicular to the preimage
The relationship between two slopes that are perpendicular to each other is
slope of line, m = -1/slope of the perpendicular line, m'
m' = -1/m
m' = -1/3

Eight times the square of a negative
integer plus 24 times the negative
integer equals 80. Find the unknown
negative integer.
Answer:
-2
Step-by-step explanation:
8(-a)^2+24*-a=80
or,8a^2-24a=80
or,8a^2-24a-80=0
or,8(a^2-3a-10)=0
or,a^2-3a-10=0
or,a^2-(5-2)a-10=0
or,a^2-5a+2a-10=0
or,a(a-5)+2(a-5)=0
or,(a-5)(a+2)=0
either,
a-5=0
•°•a=5
or,
a+2=0
•°•a=-2(negative integer)
The value of the unknown integer is -2.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given data eight times the square of a negative integer plus 24 times the negative integer equals 80 in the form of the mathematical expression will be written as:-
8(-a)²+24-a=80
8a²-24a=80
8a²-24a-80=0
8(a²-3a-10)=0
a²-3a-10=0
a²-(5-2)a-10=0
a²-5a+2a-10=0
a(a-5)+2(a-5)=0
(a-5)(a+2)=0
a-5=0
a=5 or, a+2=0 a=-2
Therefore, the value of the unknown integer is -2.

Answer:
$80 + $32x = y
Step-by-step explanation:
80 dollars is mandatory, and will always be charged no matter how many hours the electrician works. The $32 is charged based on how many hours the electrician worked. We don't know how many hours he worked, therefore we put an X next to $32 as a way to remind ourselves to multiply the amount of hours he worked times how much he charges per hour. Y would be the total fee.

f(0) and f(2) in function notation form
Answers:
f(0) = 1
f(2) = 5
============================================
Explanation:
Determining f(0)
The y intercept point (0,1) indicates that x = 0 and y = 1 pair up together. Recall that y = f(x), which means f(x) = 1 when x = 0. This is shortened to f(0) = 1.
-----------------
Determining f(2)
Start at 2 on the x axis. Draw an arrow pointing directly upward until you get to the curve. See the diagram below. Then move to the left until you hit the y axis. You should arrive at y = 5.
This tells us x = 2 and y = 5 pair up together. Therefore, f(2) = 5.

11.)60 degrees the lines on the triangle (the lil dashes) mean that that all the sides are equal making all the angles equal as well so all the angles equal 60 degrees.
12.) no, because in order for all the sides to be 12ft the angles have to be 60 degrees and this one is only 58 degrees so it wont exactly reach 12ft

Answer:
64 bags
Step-by-step explanation:
number of bags sold by Takis Scorpion BBQ = x
Number of bags sold by Takis Valcano Quesco = 3x - 6
the total number of bags = x + ( 3x - 6 )
x + 3x - 6 = 250
therefore, 4x - 6 = 250
4x = 250 + 6
4x = 256
dividing through by 4
x = 64
