The points H = (3,7); J = (0,4); K = (-1,8) and M = (-3,-4) can either be a relation or a function
The domain is: [-3,-1,0,3]The range is: [-4,4,7,8]The ordered pair is a functionThe range of the table is [tex]y \ge 0[/tex]The graph of the pointsThe points are given as:
H = (3,7); J = (0,4); K = (-1,8) and M = (-3,-4)
See attachment for the graph of the points
The domain of the pointsThis is the set of the x coordinates of the points
Hence, the domain is: [-3,-1,0,3]
The range of the pointsThis is the set of the y coordinates of the points
Hence, the range is: [-4,4,7,8]
How to determine if the ordered pair is a functionRecall that the points are:
H = (3,7); J = (0,4); K = (-1,8) and M = (-3,-4)
Rewrite the points using mapping
[tex]\left[\begin{array}{c}3&0&-1&-3\end{array}\right] \to \left[\begin{array}{c}7&4&8&-4\end{array}\right][/tex]
None of the x values point to multiple y values.
Hence, the ordered pair is a function
How to complete the tableThe function is given as:
[tex]f(x) = x^2[/tex]
When x = -1, we have:
[tex]y = (-1)^2 =1[/tex]
For other values, we have:
[tex]y = (0)^2 =0[/tex]
[tex]y = 1^2 =1[/tex]
[tex]y = 2^2 =4[/tex]
Hence, the complete table is:
[tex]\left[\begin{array}{ccc}x&f(x) = x^2&f(x)\\-1&y= (-1)^2&1\\0&y= 0^2&0&1&y= 1^2&1&2&y= 2^2&4\end{array}\right][/tex]
Hence, the range of the function is [tex]y \ge 0[/tex]

Answer:
∠ x = 20°
Step-by-step explanation:
Complementary angle sum to 90° , so
2x + x + 30 = 90°
3x + 30 = 90° ( subtract 30 from both sides )
3x = 60° ( divide both sides by 3 )
x = 20°
Answer:
X = 70
Step-by-step explanation:
[tex]x + 30 + 2x = 90 \\ 3x - 30= 90 \\ x - \frac{30}{3} = \frac{90}{3} \\ x - 10 = 30 \\ Add 10 to \: both \: sides: \\ x-10+10=30+10 \\ Simplify \: the \: arithmetic: \\ x=30+10 \\ Simplify \: the \: arithmetic: \\ x=40[/tex]

Will give brainilest if correct Element X decays radioactively with a half life of 15 minutes. If there are 770 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 32 grams?
Answer:
The time it'd take for the element to have 15 g of mass is approximately 68 min.
Step-by-step explanation:
The radioactive decay of a substance is given by the following formula:
Since the element has a half life of 12 minutes, this means that after this time the mass of the element will be half of it was originally, therefore:
Therefore the mass of the element is given by:
If the initial mass is 760 g and the final mass is 15 g, we have:
The time it'd take for the element to have 15 g of mass is approximately 68 min.Step-by-step explanation:

Step: Solvey=
−1/2x+8for y:y=−1/2x+8
Step: Substitute
−1/2x+8foryin3x+4y=36:
3x+4y=363x+4(−1/2
x+8)=36
x+32=36(Simplify both sides of the equation)
x+32+−32=36+−32(Add -32 to both sides)
x=4
Step: Substitute4forxiny=
−1/2x+8:y=−1/2x+8
y=−1/2(4)+8
y=6(Simplify both sides of the equation)
Answer:
x=4 and y=6
[tex]3x+4y=36\\y=-\frac{1}{2} x+8\\\\[/tex]
Since we know the value of y in the second equation, let us plug it into the first equation
[tex]3x+4(-\frac{1}{2} x+8) = 36\\3x-2x+32 = 36\\x = 4[/tex]
Now let us plug our known value of x into the second equation, [tex]y=-\frac{1}{2} x+8[/tex]
[tex]y=-\frac{1}{2} x+8 =- \frac{1}{2} *4+8 = 6[/tex]
So x = 4 and y = 6

Finally, I can put my answer!
please answer these questions.
Answer:
Step-by-step explanation:
[tex]13) \dfrac{5}{x}=\dfrac{20}{16}[/tex]
In the numerator, 20 ÷ 4 = 5
So, x = 16 ÷ 4 = 4
5 : 4 = 20:16
14)
[tex]\dfrac{2}{9}=\dfrac{12}{x}[/tex]
In the numerator, 2*6 = 12
So, x = 9*6 = 54
2:9 = 12 : 54
15) [tex]\dfrac{x}{1}=\dfrac{30}{3}[/tex]
In the denominator 3 ÷ 3 = 1
So, 30 ÷ 3 = 10
10 : 1 = 30 : 3
[tex]16)\dfrac{x}{5}=\dfrac{21}{35}[/tex]
In the denominator, 35 ÷ 7 = 5
x = 21 ÷ 7 = 3
3 : 5 = 21 : 35
[tex]17) \dfrac{21}{x}=\dfrac{7}{2}[/tex]
In the numerator, 7 *3 = 21
So, x = 2*3 = 6
21: 6 = 7 : 2

Which one of the following equations is equivalent to the equation ?
A
6x−22=26x-22=2
We simplify the equation :
2(x+3) + 5x = 34
= 2x + 6 + 5x
= 7x + 6
So, 7x + 6 = 34
x = (34-6)/7 = 4
Equation A : 6x - 22 = 2
x = (22+2)/6 = 4 (so it's equvalent).
Equation B : x/5 = 4
x = 4 x 5 = 20 (not equivalent)
Equation C :
3x - 6 = 12
x = (12+6)/3 = 6 (not equivalent)
Equation D : 6x = 18
x = 18/6 = 3 (not equivalent)
So, it's equation A

How to find circumcenter of a triangle with vertices.
Answer:
The circumcenter of a triangle is defined as the point where the perpendicular bisectors of the sides of that particular triangle intersect. In other words, the point of concurrency of the bisector of the sides of a triangle is called the circumcenter. It is denoted by P(X, Y). The circumcenter is also the centre of the circumcircle of that triangle and it can be either inside or outside the triangle.
Step-by-step explanation:
Steps to find the circumcenter of a triangle with vertices are:
Calculate the midpoint of given coordinates, i.e. midpoints of AB, AC, and BC
Calculate the slope of the particular line
By using the midpoint and the slope, find out the equation of the line (y-y1) = m (x-x1)
Find out the equation of the other line in a similar manner
Solve two bisector equations by finding out the intersection point
Calculated intersection point will be the circumcenter of the given triangle
Which set of side lengths form a right triangle?
8 cm, 17 cm, 14 cm
50 in., 48 in., 14 in.
3 ft, 6 ft, 5 ft
53 m, 48 m, 24 m
Answer:
50, 48, 14
Step-by-step explanation:
Go through them one by one. The side lengths of a triangle should all plug in to the formula a^2 + b^2 = c^2. The longest side is always c because it is the hypotenuse. The other two sides are interchangeable.
8^2+ 14^2 should equal 17^2.
That simplifies to
64+196=289
That can't be true because the units digits add to 10 instead of 9.
The same method applies to 3, 5, and 6 but from experience I know that this already isn't an option.
For 50, 48, and 14, you can divide everything by 2, resulting in 25, 24, and 7.
576+49 should equal 625.
That is true.
For 53, 48, and 24
576+2304 should equal 2809.
That isn't true, it equals 2880.
