M(8, 5) is the midpoint of JK. The coordinates of point J are (5, −6) . What are the coordinates of point K?
Answers
The midpoint is the exact middle of a line segment which divides the line into two equal lengths. Hence, the coordinate of K is (11, 16)
We can obtain the distance between the coordinates of JM thus :
Distance = y2 - y1 ; x2 - x1
Distance = (8 - 5) ; (5 - (-6) = (3, 11)
Hence, the change in the coordinates is (3, 11)
Therefore, the coordinates of K can be obtained thus :
(8 + 3) ;(5 + 11) = (11, 16)
Hence, the coordinate of K is (11, 16)

Which unit fraction should be used to convert 15 inches to centimeters?
Answers
To convert from inches to centimeters, the unit fraction used is 2.54 cm/1 in. Therefore, 15 inches is equal to 38.1 centimeters.
Explanation:To convert a measurement from inches to centimeters, we utilize a unit conversion factor. In this instance, the unit conversion factor we're interested in relates inches to centimeters. One inch is equivalent to 2.54 centimeters. Hence, the unit fraction used for such conversion is 2.54 cm/1 in.
To determine the equivalent value in centimeters for 15 inches, we multiply the number of inches (15) by our unit conversion factor (2.54 cm/1 in). This gives us the following
15 inches * 2.54 cm/1 in = 38.1 cm.
So, 15 inches is equivalent to 38.1 centimeters when converted.

holly and melanie were playing a video game. the ratio of holly's score to melanie's score was 8:3. after melanie scored 34 points, the ratio of their scores became 2:5. what were their scores at the end?
Answers
Since we don't know the actual numbers, let's say their scores were originally 8x for Holly and 3x for Melanie.
Then Melanie scored 34 points, so her score became 3x + 34.
Holly's score remained the same at 8x.
The new ratio is 2:5, so
8x/(3x + 34) = 2/5
Now we solve the equation for x.
40x = 6x + 68
34x = 68
x = 2
With x, we can find the scores.
Holly ended up with 8x = 8 * 2 = 16
Melanie ended up with 3x + 34 = 3(2) + 34 = 40

The equation of line m is 5x−3y=2. What is the slope of a line that is perpendicular to line m? Enter your answer in the box.
Answers
y=-5/-3x+2/-3
y=5/3x-2/3
compare y=mx+c || m =5/3
for perpendicularity
m=-1/M
m=-1/5/3
m= -3/5
Step 1
Find the slope of the line M
we have
[tex]5x-3y=2[/tex]
isolate the variable y
[tex]3y=5x-2 \\ \\y=\frac{5}{3}x-\frac{2}{3}[/tex]
the slope of the line is [tex]\frac{5}{3}[/tex]
Step 2
Find the slope of the line perpendicular to line M
we know that
if two lines are perpendicular , then the product of their slopes are equal to minus one
so
[tex]m1*m2=-1[/tex]
we have
[tex]m1=\frac{5}{3}[/tex]
Find m2
[tex]m2=-1/m1[/tex]
[tex]m2=-1/(5/3)[/tex]
[tex]m2=-\frac{3}{5}[/tex]
therefore
the answer is
[tex]-\frac{3}{5}[/tex]

Answer : Option B is correct.
Explanation :
Since we have given that
f(x) = x+1
and
g(x) =x
and when we divide f(x) with g(x) i.e.
[tex]\frac{f(x)}{g(x)}[/tex]
And we know the division algorithm , i.e.
[tex]f(x)=g(x).q(x) +r(x)[/tex],
Where q(x) represents quotient and r(s) denotes remainder
So, we write it in this manner ,
[tex]x+1=x.1+1\\\\\text{Remainder becomes 1}[/tex]
Hence, Remainder = 1
So, Option B is correct.
The sum of two numbers is 39 . the larger number is 17 more than the smaller number. what are the numbers?
Answers
Larger Number = S + 17
Smaller Number = S
S + 17 + S = 39
2S + 17 = 39
2S = 39 - 17
2S = 22
S = 22/2
S = 11
Larger Number is S + 17
Larger Number is 11 + 17
Larger Number is 28
Smaller Number is 11
The smaller number is 11 and the larger number is 28.
Explanation:Let's assume the smaller number is 'x'.
The larger number is 17 more than the smaller number, so the larger number can be represented as 'x + 17'.
The sum of the two numbers is 39, so we can set up the equation: x + (x + 17) = 39.
By simplifying the equation, we get 2x + 17 = 39.
Subtracting 17 from both sides gives us 2x = 22.
Dividing both sides by 2 gives us x = 11.
So, the smaller number is 11 and the larger number is 11 + 17 = 28.

Which operation flips the graph of a function over the x-axis?

Answers
A. multiplying the function by -1
Multiplying the function by –1 is the operation flips the graph of a function over the x-axis
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The operation that flips the graph of a function over the x-axis is multiplying the function by -1.
When a function is multiplied by -1, the y-values are negated, which causes the graph to reflect over the x-axis.
if we have a function f(x) = x², the graph will be a parabola that opens upwards.
However, if we multiply this function by -1 to get -f(x) = -x², the graph will be the same parabola reflected over the x-axis and opening downwards.
Hence, Multiplying the function by –1 is the operation flips the graph of a function over the x-axis

(5 1/4)÷(−2 1/2)
Enter your answer as a mixed number, in simplified form, in the box. Please Explain your answer.
Answers
To divide (5 1/4)÷(−2 1/2), convert the mixed numbers into improper fractions and then multiply by the reciprocal of the divisor. Simplify the result to get the quotient as -2 1/10.
Explanation:To divide the given mixed numbers, (5 1/4)÷(−2 1/2), we first convert them into improper fractions.
5 1/4 can be written as (4*5 + 1)/4 = 21/4.
(−2 1/2) can be written as (-2*2 + 1)/2 = -5/2.
Now, we can divide the fractions by multiplying the reciprocal of the divisor: (21/4) * (-2/5) = (-21/4) * (2/5) = -21/10.
Finally, we simplify the result by dividing both the numerator and the denominator by their greatest common factor, which is 1. The simplified result is -21/10, which can be written as -2 1/10 as a mixed number.

notice the area is just a 3x3 square and a triangle with a base of 3 and a height of 3, simply get the area of both, add them up, and that's the area of the piece-wise on that range.
Answer:
13.5
Step-by-step explanation:
The geometric representation of an integral is the area below the curve. So, let's graphic the function.
[tex]f(x) = 3[/tex] is an horizontal line, (y = 3)
and [tex]f(x) = 6-x[/tex] is also a line, but it is decreasing.
We can see in the image that the area below the curve happens to be a polygon. In order to calculate the area we are going to separate it into simpler polygons: a square and a triangle.
The area of the square is [tex]3*3 = 9[/tex].
The area of the triangle is [tex]\frac{3*3}{2} = \frac{9}{2} = 4.5[/tex]
If we add them, we get
[tex]\int_0^6 f(x) dx =9 + 4.5 = 13.5[/tex]
