Answer:
y = - 21
Step-by-step explanation:
System of equations:
- 6x + 2y = - 18
- 3x - 2y = 54
To find y will look to eliminate x:
- 6x + 2y = - 18
- 3x - 2y = 54 (multiply both sides by -2)
- 6x + 2y = - 18
6x + 4y = - 108
---------------------------- (add those two equations)
6y = - 126 (divide both sides by 6)
y = - 126/6 (simplify by 6)
y = - 21
Answer: -21

Jason is considering two different jobs that he has been offered and he likes the atmosphere and
other employees equally at both companies.
With the first job he would be an apartment property manager for AMLI Company. This job is
offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he
sets a one year lease up with. The company expects Jason to work all 52 weeks of the year and 40
hours per week. He was told he could expect to set up an average of 5 lease agreements for each
week that he works.
With the second job he would work as water treatment facility manager in Gwinnett County. He
would be paid an annual salary of $46,000 a year, there are no bonuses by he gets a week off.
Both companies deduct for Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and
Federal Income Tax (14%).
AMLI's individual health insurance costs $115 per month. Gwinnett County's health insurance is
only $25 per month for an individual.
Part A: Determine how much Jason will receive in one year after all deductions have been taken
for each company. Show your work neatly.
The amount of money that Jason will receive in one year after all deductions have been taken for each company is $30,780.5 and $32562.
What is the final amount?With the first job, he would be an apartment property manager for AMLI Company.
This job is offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he sets a one-year lease-up with.
The company expects Jason to work all 52 weeks of the year and 40 hours per week.
He was told he could expect to set up an average of 5 lease agreements for each week that he works.
The amount after one year will be given by an equation
Let y be the amount, x be the number of hours in a week and z be the number of the week.
y = 19x + 40z
The total number of hours in a year will be
x = 2080
Then
y = 19 × 2080 + 40 × 52
y = $ 41,600
The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be
→ 41,600 × 0.938 × 0.988 × 0.97 × 0.86
→ $ 32,160.5
The amount after the insurance will be
Amount = 32160.5 - 115 × 12
Amount = $ 30780.5
With the second job, he would work as a water treatment facility manager in Gwinnett County. He would be paid an annual salary of $46,000 a year, there are no bonuses and he gets a week off.
The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be
→ 46,000 × 0.938 × 0.988 × 0.97 × 0.86
→ $ 35,562
The amount after the insurance will be
Let the number of the worker be 10. Then
Amount = 35,562 - 10 × 12 × 25
Amount = 35562 - 3000
Amount = $32562

A. Zero product property
B. quadratic formula
C. square root property
The value of x by using the zero product property therefore option A is correct.
We have given that,
(x+3)(x+2)=0
we have to determine the technique that is most appropriate to use to solve each equation
What is the zero product property?The Zero Product Property simply states that if ab = 0, then either a = 0 or b = 0 (or both).
Therefore we have
(x+3)=0 and (x+2)=0
This implies that,
x+3=0
x=-3 and (x+2)=0 this implies that x=-2
Therefore we get the value of x by using the zero product property therefore option A is correct.

A rectangle has sides measuring (6x + 4) units and (2x + 11) units.
Part A: What is the expression that represents the area of the rectangle? Show your work.
Part B: What are the degree and classification of the expression obtained in Part A?
Part C: How does Part A demonstrate the closure property for polynomials?
Answer:
Down Here ↓↓↓
Step-by-step explanation:
Hello!
A)
The area of a rectangle is L * W.
Area = (6x + 4)(2x + 11)Area = 12x² + 8x + 66x + 44Area = 12x² + 74x + 44B)
The degree of a polynomial is the value of the highest exponent. The degree of 12x² + 74x + 44 is 2, because 2 is the highest exponent.
C)
This demonstrates the closure property, as adding, subtracting, and or multiplying polynomials will give a polynomial.

Step-by-step explanation:
We will put this in y=mx +b form so first calculate the slope
m= (-4)-(-5)/(-4)-(-6)
m= 1/2. So y= x/2. +b
Now just substitute the x and y values of either given point to calculate b

Subtract 20 from both sides
0.70m = 25 + 0.25m
Subtract 0.25m from both sides

Option B, [tex]516.3\ units[/tex]
Step-by-step explanation:
Step 1: Determine the area of the back
[tex]A = l * w[/tex]
[tex]A = 10\ units * 13\ units[/tex]
[tex]A = 130\ units^2[/tex]
Step 2: Determine the hypotenuse
Pythagorean theorem → [tex]a^2 + b^2 = c^2[/tex]
[tex](10-6)^2\ units + 7^2\ units = c^2[/tex]
[tex]4^2\ units + 7^2\ units=c^2[/tex]
[tex]16\ units+49\ units=c^2[/tex]
[tex]\sqrt{65}=\sqrt{c^2}[/tex]
[tex]8.06 = c[/tex]
Step 3: Determine the area of the top
[tex]A = l * w[/tex]
[tex]A = 13\ units * 8.06\ units[/tex]
[tex]A = 104.81\ units^2[/tex]
Step 4: Determine the area of the front
[tex]A = l * w[/tex]
[tex]A = 13\ units * 6\ units[/tex]
[tex]A = 78\ units^2[/tex]
Step 5: Determine the area of the bottom
[tex]A = l * w[/tex]
[tex]A = 13\ units * 7\ units[/tex]
[tex]A = 91\ units^2[/tex]
Step 6: Determine the area of the trapezoid
[tex]A = \frac{a + b}{2} * h[/tex]

Find the equation of the circle in standard form.
center (5,-5)
radius = 3 units
Answer:
(x - 5)² + (y + 5)² = 9
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k ) = (5, - 5 ) and r = 3 , then
(x - 5)² + (y - (- 5) )² = 3² , that is
(x - 5)² + (y + 5)² = 9
