Which set of ordered pairs does not represent a function?
\{(2, 7), (1, 7), (0, -8), (5, -1)\}{(2,7),(1,7),(0,−8),(5,−1)}
\{(-1, -9), (-5, -2), (8, 4), (-5, 2)\}{(−1,−9),(−5,−2),(8,4),(−5,2)}
\{(3, 1), (5, 5), (9, 8), (7, 6)\}{(3,1),(5,5),(9,8),(7,6)}
\{(2, 0), (1, -6), (4, 5), (-8, -6)\}{(2,0),(1,−6),(4,5),(−8,−6)}
Answer:
The second option
Step-by-step explanation:
There can NOT be a function when one x-value coordinate corresponds to multiple x-values. -5 is corresponding with two different y-values, -2 and 2.
What is the slope of a line which passes through the points (-6, 4) and (4, 6)?
A) 5
B)1/5
C)2
D)1/2
Answer:
1/5
Step-by-step explanation:
To find the slope between two points, we use the formula
m = ( y2-y1)/(x2-x1)
= ( 6-4)/(4 - -6)
= ( 6-4)/(4+6)
= 2/10
= 1/5

CALCULATOR COLOR THEME 0 ZOOM 2. Danielle wants to translate triangle XYZ so that vertex Yis mov (-4,2) to (0,-3). Which of the following mappings can be used to coordinates of Xand Z?
Answer:The answer is (x,y)->(+4,y-5)
Step-by-step explanation:
since -4 to 0 is + 4 and 2 to -3 is -5
The correct mapping is (x, y) ⇒ (x + 4, y - 5)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).
Since the vertex Y(-4, 2) was translated to Y'(0, -3), hence the triangle was translated 4 units to the right (-4 + 4 = 0) and 5 units down (2 - 5 = -3). This can be represented by the mapping:
(x, y) ⇒ (x + 4, y - 5)
Therefore to find x and z coordinates, use the mapping:
(x, y) ⇒ (x + 4, y - 5)

At noon the temperature was -10° F. Over the next 4 hours the temperature went up 12°. Then every hour until 10 pm the temperature dropped 2°. What was the temperature at 10 pm?
Answer:
-10 degrees
Step-by-step explanation:
at noon the temp was -10. -10 + 12 = 2 and that is at 4 o'clock 2- 6 hours ( time until 10 pm) x 2. 2 - 12 = -10.
Answer: 0º F.
Step-by-step explanation:
Noon = 12 pm
At Noon it was -10º F, over the next 4 hours it went up to 12º F.
Noon + 4 hours = 4 pm
The temperature dropped 2º F every hour until 10 pm which means for 6 hours the temperature dropped.
6x2º F = 12º F which means the temperature dropped by 12º F.
12º F - 12º F = 0º F

Devin is collecting signatures for a petition to open a new park in her town. She needs to collect at least 1,000
signatures before she can schedule a meeting with the mayor. She already has 380 signatures. If each petition page
holds 80 signatures, which inequality best shows how many more pages (p) Devin needs?
Answer:
P = t - f
Step-by-step explanation:
First we need to find how many pages in total she needs so 1,000/80 - 12.5 so 13 pages. Then 380/80 4.75 of a page filled so subtract that from 12.5 to get 8 pages left to fill.
let p = pages left to fill
let T = total pages needed
let F = pages already filled

Answer:
x = 29
Step-by-step explanation:
The sum of the 3 angles is 180 degrees since it is a straight line
x-1 + 3x+2 + 2x+5 = 180
Combine like terms
6x +6 = 180
Subtract 6 from each side
6x+6-6= 180-6
6x =174
Divide y 6
6x/6 =174/6
x = 29
Answer:
it's 29
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
The equation represents Function A, and the graph represents Function B:
Function A f(x) = 6x - 1
Function B graph of line going through ordered pairs 1, 4 and negative 1, negative 2 and negative 2, negative 5
Which equation best compares the slopes of the two functions?
(A) Slope of Function B = 2 x Slope of Function A
(B) Slope of Function A = Slope of Function B
(C) Slope of Function A = 2 x Slope of Function B
(D) Slope of Function B = − Slope of Function A
Answer:
C. Slope of Function A = 2 x Slope of Function B
Step-by-step explanation:
The slope of function A is the x-coefficient: 6.
The slope of function B is ...
... slope = (change in y)/(change in x) = (-2-4)/(-1-1) = -6/-2 = 3

Answer:
option b: square root
Step-by-step explanation:
just got correct on edge 2020
The family of the function belongs to square root.
We can solve this by understanding some types of functions
What is Function?This is an expression that relates two variable to one another.
In this question, we are looking for the family of the equation.
The function given is
[tex]y = (x + 2)^\frac{1}{2} + 3[/tex]
The options given here are
quadraticsquare rootexponentialreciprocalWhat is a quadratic equation?This is a polynomial that the variable have the highest power of 2. An example of this is [tex]y = ax^2 + bx + c[/tex]
What is a square rootThis a function in which the variable is a square root to the main function.
An example of this is [tex]y = \sqrt{x}[/tex]
What is an Exponential FunctionThis is a function in which one of the variable has an exponential function to the other. An example of this is [tex]y = 2e^x[/tex]
What is a Reciprocal FunctionThis is a function in which one of the variable is inverse to the other one. An example of this is [tex]y = \frac{1}{x}[/tex]
From the above explanation, we can see that the function
[tex]y = (x + 2)^\frac{1}{2} +3\\y = \sqrt{x+2} + 3[/tex]
is a square root function
