Answer: y = (1/2)x-2
This is the same as y = 0.5x-2
Slope = 1/2 = 0.5
Y intercept = -2
========================================================
Work Shown:
Compare the equation to y = mx+b to find that m = -2 is the slope.
Think of -2 as -2/1. Flip the fraction to get -1/2. Then flip to positive getting 1/2.
The original slope is -2. The perpendicular slope is 1/2 = 0.5
We'll use this perpendicular slope alone with (x,y) = (-4,-4) to get the following for b
y = mx+b
-4 = 0.5*(-4) + b ... plug in the m,x, and y values mentioned above
-4 = -2 + b
-4+2 = b ... adding 2 to both sides
-2 = b
b = -2
Since m = 0.5 and b = -2, we go from y = mx+b to y = 0.5x-2
This is the same as y = (1/2)x-2 since 1/2 = 0.5

The area of a square garden is 9ft. How long is each side of the garden
Answers
The length of each side of the square garden is 3ft.
What is a square?A square is a quadrilateral with four equal straight sides and four right angles.
To find the area of a square garden, multiply two equal sides.
The area is the space of a two-dimensional line.
To find the length of each side of a square garden, compute the squared root of the area.
Area of the square garden = 9 ft
Length of each side = √9
= 3 feet
Thus, each side of the garden has 3 ft.

Write the equation of the line that passes through the points (-3, -7) and (-3,-4) put your answer in fully reduced point slope form unless it is a vertical or horizontal line
Answers
Answer:
It is an undefined line which means a vertical line.
Step-by-step explanation:
Using the point-slope formula y2-y1 divided by x2-x1, you would get -4-(-7)/-3-(-3) which the answer would be 3/0. If zero is at the bottom of the fraction, the line would be undefined.

A Major League Baseball stadium sells three types of tickets. Reserved tickets are sold for $20 each, field-level tickets are sold for $50 each, and box seat tickets are sold for $100 each. You purchase 10 total tickets for $370. You have twice as many reserved tickets as field-level tickets.
Answers
Answer:
There were 6 reserved tickets, 3 field level tickets and 1 box seat tickets
Step-by-step explanation:
Let x represent the number of reserved tickets, y represent the number of field level tickets and z represent the number of box seat tickets.
Given that 10 total tickets were bought for $370, hence this can be represented by the equation:
20x + 50y + 100z = 370 (1)
x + y + z = 10 (2)
Also there was twice as many reserved tickets as field-level tickets. This can be represented by the equation:
x = 2y
x - 2y = 0 (3)
solving equations 1, 2, and 3 simultaneously gives:
x = 6, y = 3 and z = 1
There were 6 reserved tickets, 3 field level tickets and 1 box seat tickets

The hourly wage increases each employee receives each year depends on the number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00 per hour. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00 per hour. Choose a function to represent this scenario
Answers
Answer:
________{0.50 if x < 3
________{1.00 if 3 ≤ x < 6
f(x) = ____{1.50 if 6 ≤ x < 9
________{2.00 if 9 ≤ x < 12
Step-by-step explanation:
Given the information above :
Less than Employees = $0.5 increase per hour
Atleast 3 but less than 6 years employees = $1.00 increase per hour
Atleast 6 but less than 9 years employees = $1.50 increase per hour
Atleast 9 but less than 12 years employees = $2.00 increase per hour
The information above can be written as a piecewise function :
________{0.50 if x < 3
________{1.00 if 3 ≤ x < 6
f(x) = ____{1.50 if 6 ≤ x < 9
________{2.00 if 9 ≤ x < 12
The constraints is represented in the piecewise function above with x being the number of years since employee has been in service.
