Find an equation for the perpendicular bisector of the line segment whose endpoints are (5, 5) and ( 7, 1).
Answer:
x -2y = 0
Step-by-step explanation:
A perpendicular bisector is a line perpendicular to a given line or segment that goes through the midpoint between given points. The perpendicular line will have a slope that is the opposite reciprocal of the slope of the segment between the given points.
__
The midpoint between A and B is ...
M = (A +B)/2
M = ((5, 5) +(7, 1))/2 = (12, 6)/2 = (6, 3)
The slope of the line between A and B is ...
m = (y2 -y1)/(x2 -x1)
m = (1 -5)/(7 -5) = -4/2 = -2
__
The opposite reciprocal of the slope of the given segment is ...
m' = -1/-2 = 1/2
The point-slope form of the equation of the perpendicular bisector can be written as ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -3 = 1/2(x -6) . . . . line with slope 1/2 through point (6, 3)
Multiplying by 2 gives ...
2y -6 = x -6
Subtracting (2y -6) gives the standard-form equation ...
x -2y = 0

A new fitness center opens with 120 members. Every month the fitness center increases the number of members by 40 members. How many members will the fitness center have after being open for 3 months?
Answer:
240 members
Step-by-step explanation:
Let y = total and x = no. of months
y = 40x + 120
= 40(3) + 120
= 120 + 120
= 240 members

Micha works at a sporting goods store. He is paid $8.25 per hour plus double time on holidays and makes an average of 8% commission on all golfing equipment sales. This is modeled by the expression 8.25(x) + 8.25(2)(y) + 0.08(z). What is Micha's gross pay if he worked 15 regular hours and 4 holiday hours and had $562.00 in golf equipment sales.
$153.00

Answer:
C
Step-by-step explanation:

An expression is defined as a set of numbers, variables, and mathematical operations. The gross pay of Micha for the given month is $234.71. The correct option is C.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given that Micha is paid $8.25 per hour plus double time on holidays and makes an average of 8% commission on all golfing equipment sales, which is modeled by the expression 8.25(x) + 8.25(2)(y) + 0.08(z).
Now, if Micha worked 15 regular hours and 4 holiday hours and had $562.00 in golf equipment sales. Therefore, the value of x, y, and z is,
Regular hours, x = 15
Holiday hours, y = 4
Sales made in dollars, z = 562
Substitute the values in the given expression to get the gross pay of Micha in the given year,
Gross pay = 8.25(x) + 8.25(2)(y) + 0.08(z)
= 8.25(15) + 8.25(2)(4) + 0.08(562)
= $123.75 + $66 + $44.96
= $234.71
Hence, the gross pay of Micha for the given month is $234.71.

Tim made 10 baskets during a basketball game. Each basket was worth either 2 or 3 points. How many different numbers could represent the total points scored by Jordan? What's the answer?
The total point is an illustration of arrangements
There are 6 different numbers that could the total points scored by Tim
How to determine the number of total points?The different number (n) that can represent the total point is calculated as:
n = 2 points + 3 points + 1
Remove the units
n = 2 + 3 + 1
Evaluate the sum
n = 6
Hence, there are 6 different numbers that could the total points scored by Tim

f(x) = (2x − 3)(x + 6)(5x + 6) has zeros at x = -6, x = -6/5 and x =3/2.
What is the sign of f on the interval - 6
Answer:
Step-by-step explanation:
f ( - 7 ) = [ 2 ( - 7 ) - 3]( - 7 + 6 )[ 5 ( - 7 ) + 6 ] = ( - 17 )( - 1 )( - 29 ) < 0 , Negative
f ( - 5 ) = [ 2 ( - 5 ) - 3]( - 5 + 6 )[ 5 ( - 5 ) + 6 ] = ( - 13 )( + 1 )( - 19 ) > 0 , Positive
f ( - 1 ) = [ 2 ( - 1 ) - 3]( - 1 + 6 )[ 5 ( - 1 ) + 6 ] = ( - 5 )( + 5 )( + 1 ) < 0 , Negative

Write a function rule for the table.
f(x) = 4 – x
f(x) = –4x
f(x) = x + 4
f(x) = x – 4
Answer:
f(x) = x – 4
checking for all the functions by replacing x as 3
f(x) = 4 – x
f(3) = 4 - 3
f(3) = 1
does not match
f(x) = –4x
f(3) = -4(3)
f(3) = -12
does not match
f(x) = x + 4
f(3) = 3 + 4
f(3) = 7
does not match
f(x) = x – 4
f(3) = 3 - 4
f(3) = -1
matches
Answer:
f(x) = x - 4
Step-by-step explanation:
The options are:
f(x) = 4 – x
f(x) = –4x
f(x) = x + 4
f(x) = x – 4
For f(x) = 4 – x, when x=3, f(x)=1 so it cannot be right.
For f(x) = –4x, when x=3, f(x)=-12 so it cannot be right either.
f(x) = x + 4, when x=3, f(x)=7 so it cannot be right.
The only choice left which is also the right answer is f(x) = x – 4

Step-by-step explanation:
given
(2x + 5)(2x - 1) ← expand using FOIL
(a)
= 4x² - 2x + 10x - 5 ← collect like terms
= 4x² + 8x - 5
(b)
using the method of completing the square on
4x² + 8x - 5 ← factor out 4 from the 1st 2 terms
= 4(x² + 2x) - 5
to complete the square
add/ subtract ( half the coefficient of the x- term )² to x² + 2x
= 4(x² + 2(1)x + 1 - 1) - 5
= 4(x + 1)² - 4 - 5
= 4(x + 1)² - 9

Triangle ABC has angle measures as shown below. Using the information in the diagram, find the value of x.
In your answer, give the value of x and explain how you calculated it.
Solution:
The interior angles of a triangle sum up to 180°
This means that...
3(x + 2) + 52 + 35 = 180Simplify the distributive property.
3x + 6 + 52 + 35 = 180Combine like terms.
3x + (6 + 52 + 35) = 180=> 3x + (93) = 180Subtract 93 both sides.
3x + (93) = 180=> 3x + 93 - 93 = 180 - 93Simplify both sides.
=> 3x = 87Divide 3 both sides.
=> 3x/3 = 87/3 => x = 87/3 = 29Select the correct answer.
