which of the following ordered pairs could not be included in this set if its a function? (-4,2) (3,6) (4,3) (?,?)
(-4,-3)
(1,2)
(3,6)
(-3,6)
Given:
The set of ordered pair (-4,2), (3,6), (4,3), (?,?).
To find:
The ordered pairs that could not be included in this set if its a function.
Solution:
We know that, a relation or a set of ordered pairs is a function if there exist a unique output (y-value) for each input (x-value).
If (-4,-3) point is included in the given set of ordered pair, then we have [tex]y=-3,2[/tex] for [tex]x=-4[/tex].
Since there are more than one output value at [tex]x=-4[/tex], therefore the given set of ordered pairs will not be a functions after including the point (-4,-3).
If points (1,2), (3,6) and (-3,6) are included in the given set of ordered pair, then there exist a unique output for each input.
So, the given set of ordered pairs will be a functions after including the points (1,2), (3,6) and (-3,6).
Therefore, the correct option is A.

Answer:
(3, infinity)
Step-by-step explanation:
range is talking about the y axis and every number the graph touches on the y axis. the first number is the minimum number and the second number is the max number. this graph's lowest point is 3, so the answer is (3, something). the max is never/infinity and that's how you get (3, infinity).

1. Factor 3h2 - 11h - 42 completely.
Answer:
3h² - 11h - 42 = (3x+7)(x−6)
Step-by-step explanation:
We need to find factors of 3h² - 11h - 42. It is a quadratic equation.
We search two numbers such that their product is 42 and sum is 11. So,
3h² - 11h - 42 = 3h² -18x +7x -42
= (3x+7)(x−6)
So, the required factors are (3x+7)(x−6).
Determine the average rate of change in braking distance, in ft/mph, between one can traveling at 50 mph and one
traveling at 70 mph. Explain what this rate of change means as it relates to braking distance.
Answer:
306.25-156.25/70-50 =150/20=7.5 ft/mph
Step-by-step explanation:
For every 1 mph over 50 mph a car is traveling, its braking distance increases by 7.5 ft
The required braking distance between the one that can travel at 50 mph and one traveling at 70 mph is 7.5 ft/mph.
What is the rate of change?Rate of change is defined as the change in value with rest to the time is called rate of change.
Here,
Distance traveled when applying brake when speed is 70 mph is 306.25,
Distance traveled when applying brake when speed is 50 mph is 156.25 ft
The rate of change of braking is given as,
= 306.25-156.25/70-50
= 150/20
=7.5 ft/mph
Thus, the required braking distance between the one that can travel at 50 mph and one traveling at 70 mph is 7.5 ft/mph.

Write a polynomial to represent the larger rectangle and the smaller rectangle.
Answer:
See answers below.
Step-by-step explanation:
Large Rectangle: length x width = (x + 3)(x - 4) =
x² - 4x + 3x - 12
x² - x - 12
Smaller Rectangle: length x width = (x)(3) = 3x
Shaded Region: shaded area = lg. rectangle minus small rectangle
A = (x² - x - 12) - 3x
A = x² - 4x - 12
Solve for x, if shaded reion's area is 48 square units:
48 = x² - 4x - 12
x² - 4x - 12 -48 = 0
x² - 4x - 60 = 0
(x - 10)(x + 6) = 0
x - 10 = 0 or x + 6 = 0
x = 10 or x = -6
But x represents a length, so x cannot be -6.
x = 10
A cube with side of 6cm or a rectangular box of 7cm by 6cm by 4cm . find the volume
Answer:
Volume of cube = 216cm^3
Volume of box = 168cm^3
Step-by-step explanation:
Cube:
6 x 6 = 36
36 x 6 = 216
Box:
7 x 6 = 42
42 x 4 = 168
Answer:
216 cm^3, 168 cm^3
Step-by-step explanation:
Cube
Volume of a cube is the side * side * side.
Side = 6 || 6 * 6 * 6 = 216 cm^3
Rectangular Box
Volume of box is product of height, depth, and width.
Sizes are, 7, 6, 4 || 7 * 6 * 4 = 168 cm^3

PLEASE HELP FAST(solve the pre-algebra question)
Answer:
Flag = 46
Shamrock = 46
Hat = 27
Accordion = 198
Step-by-step explanation:
To keep things simple, I'll denote the flag with f, the shamrock with s, the hat with h and the accordion with a.
The second equation tells us that f/s is 1. When you divide something by something and get 1, that means they're equal (eg, 2÷2=1, 3÷3=1 etc). That means f=s.
The second equation tells us f+s+s=138, but since f=s, this basically means 3f=138. Dividing both sides by three, we find out f=46 and by extension, s=46.
The third equation tells us s+h+h=100. We know s so we can write this as 46+2h=100. Take 46 form both sides to get 2h=54. Divide both sides by 2, we find out h=27.
The fourth equation tells us a=4f+14. Sub in our value for f and this is a=(4x46)+14. Solve this to get a=184+14, a=198.
The point (7, 4) lies on a circle centered at the origin. Write the equation of the circle and state the radius.
Given:
The point (7, 4) lies on a circle centered at the origin.
To find:
The equation of the circle and the radius of the circle.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The point (7, 4) lies on a circle centered at the origin. So, the distance between the points (7,4) and (0,0) is equal to the radius of the circle.
[tex]r=\sqrt{(0-7)^2+(0-4)^2}[/tex]
[tex]r=\sqrt{(-7)^2+(-4)^2}[/tex]
[tex]r=\sqrt{49+16}[/tex]
[tex]r=\sqrt{65}[/tex]
The standard form of the circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting h=0, k=0 and [tex]r=\sqrt{65}[/tex] in (ii), we get
[tex](x-0)^2+(y-0)^2=(\sqrt{65})^2[/tex]
[tex]x^2+y^2=65[/tex]
Therefore, the equation of the circle is [tex]x^2+y^2=65[/tex] and its radius is [tex]r=\sqrt{65}[/tex].
