Line segment XY has endpoints X(5, 7) and Y(– 3, 3). Find the equation for the perpendicular bisector of line segment XY.
Answer: The equation for the perpendicular bisector of line segment xy is .
Explanation:
It is given that the line segment xy has endpoints x(5,7) and y(-3,3).
The bisector divides the line segment xy in two equal parts, so the bisector must be passing through the midpoint of xy.
Midpoint of two points (x_1,y_1) and (x_2,y_2) is calculated as,
Midpoint of xy is,
So, the perpendicular bisector must be passing through the point (1,5).
The slope of line passing through the point (x_1,y_1) and (x_2,y_2) is calculated as,
Slope of line segment is . Therefore the slope of perpendicular bisector is -2 because the the product of slopes of two perpendicular lines is always -1.
The line passing through the point (x_1,y_1) with slope m is defined as,
Bisector passing through the point (1,5) with slope 2.
Therefore, the equation for the perpendicular bisector of line segment xy is .

What is the value of f(6)
Answer:
f(6) = 35
Step-by-step explanation:
f(6) means the function value for the x-coordinate 6. To find this, we need to find out which function to use (either 0 or 35x-175). 0≤x≤5 means that f(x)=0 for any value between 0 and 5 and including 0 and 5 themselves. However, we need to find the value for x=6, so we need to use the other function (35x-175). This gives us:
f(6) = 35 * 6 - 175 = 210 - 175 = 35

find three consecutive even intergers such that the sum of the smallest number and twice the middle number is 20 more than the largest number
Answer:
10, 12, 14
Step-by-step explanation:
Hi there!
Let x be equal to the smallest integer.
Let (x+2) be equal to the next even integer.
Let (x+4) be equal to the largest even integer out of the three.
We're given:
⇒ smallest number + (2 × middle number) = 20 + largest number
Construct an equation:
[tex]x+2(x+2)=20+(x+4)[/tex]
Combine like terms:
[tex]x+2x+4=20+x+4\\3x+4=x+24\\2x=20\\x=10[/tex]
Therefore, the smallest integer is 10, making the next two even integers 12 and 14.
I hope this helps!

Which absolute value equation shows the distance this temperature reading is from zero?
For the figure shown on the right, find the value of the variable and the measures of the angles.
X=
Step-by-step explanation:
the sum of all angles in a triangle is 180 degrees.
so,
x + (x - 6) + (2x + 34) = 180
x + x - 6 + 2x + 34 = 180
4x + 28 = 180
4x = 152
x = 38 degrees
x - 6 = 32 degrees
2x + 34 = 110 degrees

Answer:
Step-by-step explanation:
Since the perimeter is 46, and opposite sides of a rectangle are equal, we know that
(x+2)+(x+2)+(2x+3)+(2x+3)=46
Combine like terms to get: 6x+10=46
Subtract 10 from both sides to get: 6x=36
Divide both sides by 6 to get: x=6.

Approximate the solution to the graphed system. Explain how you got your answer.
Answer:
(7.5, 12)Step-by-step explanation:
The solution of a linear system is the intersection of the lines.
We can see the lines A and B intersect at the point (7.5, 12) which is the solution.
See attached for better visualization.
Answer:
(7.5,12.5)
Step-by-step explanation:
See the intersected point is almost situated at the middle of 10 and 15 .Hence its 12.5 on y.And the point is situated in the middle of 7 and 8 .Hence its 7.5 on x.Find the distance in units between 1 1/2 and −2 5/6 on a number line.
Answer:
4 1/3
Step-by-step explanation:
Hypothetically, imagine 2 5/6 was postive, you add it to 1 1/2 to get your answer, but you cant do that until the fractions have a common denominator. To get a common denominator of six, you would multiply both the numerator and denominator of 1/2 by 3, giving you 3/6. Now you have 2 5/6 and 1 3/6, adding them together gives you 3 8/6, but we cant stop here, since 8/6 is 1 2/6, add 3+1 and you now have 4 2/6. The last thing you do here is simplyfy the fraction making it 1/3 now instead of 2/6. Giving you a final answer of 4 1/3 units.

The square of the difference between 2x and y
Answer:
this question doesn`t have much information but here`s my best guess
(2x-y)^2
[tex](2x - y)^2[/tex]. This expression represents the result of squaring the difference between 2x and y.
1. **Difference between 2x and y:** The difference between 2x and y is calculated by subtracting y from 2x. This gives us the expression "2x - y," which represents the numerical difference between these two quantities.
2. **Square of the Difference:** To square this difference, we simply multiply "2x - y" by itself. When you square something, you multiply it by itself. In mathematical notation, squaring is denoted using an exponent of 2, which is written as "^2."
So, combining the two steps, we have:
[tex](2x - y)^2[/tex]. This expression represents the result of squaring the difference between 2x and y. When you expand this expression, you get a quadratic expression, which may include terms like [tex]4x^2, y^2[/tex], and -2xy, among others, depending on the values of x and y.

On a number line, point S is located at -3 and point T is located at 9. What is the location of point R on ST given that the ratio of SR to RT is 3:4
A) 27/7
B) 2 1/4
C) 15/7
D) 1 1/4
Answer:
Im pretty sure it would be C
Step-by-step explanation:
The location of R on the number line will be 15/7 so option (C) will be correct.
What is a number line?In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.
In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.
A horizontal number line is the most common representation and can be extended infinitely in any direction.
Distance from S to T = 3 + 9 = 12
So,
SR + RT = 12
And given,
SR/RT = 3/4 ⇒ SR = (3/4)RT
By substitution,
(3/4)RT + RT = 12
RT ( 7/4) = 12
RT = 48/7
Now the location of point R ⇒
OT - RT = 9 - 48/7 = 15/7
Hence "The location of R on the number line will be 15/7".
