Three coworkers work for the same employer. Their jobs are warehouse manager, office manager, and truck
driver. The sum of the annual salaries of the warehouse manager and office manager is $75000. The sum of the
annual salary of the office manager and the truck driver is $75000. The annual salaries of the warehouse
manager and the truck driver total $70000. What is the annual salary of each of the co-workers?
Answer:
Let's make each of these workers' salaries a variable. For our purposes:
x = the annual salary of the warehouse manager
y = the annual salary of the office manager
z = the annual salary of the truck driver
*Since all of our variables describe an "annual salary" in dollars, we do not have to perform unit conversions.
From the sentence, "The sum of the annual salaries of the warehouse manager and office manager is $75000," we can derive the equation:
warehouse manager + office manager = 75000
x + y = 75000
From this sentence, "The sum of the annual salary of the office manager and the truck driver is $75000," we get:
office manager + truck driver = 75000
y + z = 75000
Finally, since "The annual salaries of the warehouse manager and the truck driver total $70000," we know that:
warehouse manager + truck driver = 70000
x + z = 70000
From the above equations, we can create a system of equations to reach the solution.
x + y = 75000
y + z = 75000
x + z = 70000
Using the substitution method and basic algebra, this question is easy! Let's solve for x, the warehouse manager's salary, first:
x + z = 70000
z = 70000 - x
y + z = 75000
y + (70000 - x) = 75000
y + 70000 - x = 75000
y - x = 5000
y = 5000 + x
x + y = 75000
x + (5000 + x) = 75000
x + x + 5000 = 75000
2x + 5000 = 75000
2x = 70000
x = $35000 = warehouse manager's annual salary
Now that we have solved for one of the variables, we can substitute our answer back in to get a quicker result:
x + z = 70000
(35000) + z = 70000
z = 35000$ = truck driver's annual salary
y + z = 75000
y + (35000) = 75000
y = $40000 = office manager's salary
So, our answers would be that:
The warehouse manager's annual salary is $35000.
The office manager's annual salary is $40000.
The truck driver's annual salary is $35000.

Write an equation for the area A of the figure. Then determine the maximum possible area of the figure.
Area: A=
Maximum area: ___ square units
Answer:
Step-by-step explanation:
The maximum area of the figure is 4.5 square units.
Given,
Write an equation for area A of the figure.
Then determine the maximum possible area of the figure.
What is the area of a right-angled triangle?It is given by:
Area = 1/2 x base x height
When we maximize an area we must differentiate the area.
If A is the area.
A' = 0
We have,
From the figure:
Base = 6 - b
Height = b
Now,
Area = 1/2 x base x height
Area = 1/2 x ( 6 - b ) x b
A = (6b - b²) / 2
A = 3b - b²/2
When we maximize an area we must differentiate the area and thus,
A' = 0
So,
A' = 3 - 2b/2
0 = 3 - b
b = 3
Now,
A = 3b - b²/2
A = 3 x 3 - 3²/2
A = 9 - 9/2
A = (18 - 9) / 2
A = 9/2
A = 4.5 square units.
Thus the maximum area of the figure is 4.5 square units.

Jim provides photos for two online sites: site A and site B.
Site A pays $0.85 for every photo Jim provides.
The amount in dollars (y) site B pays as a function of the number of photos provided (x) is represented by the equation y = 0.40x.
How much more was Jim paid at site A than at site B, if he provided five photos for each site? (1 point)
A. $1.15
B. $1.35
C. $2.15
D. $2.25
Answer:
Step-by-step explanation:
We can use the same equation to figure out with only substituting the amount he was paid per photo.
Site A y = $0.85x = $0.85(5) = $4.25
Site B y = $0.40x = $0.40(5) = $2.00
We can see that Jim was paid $2.25 more at site A than Site B.
Answer:
D. 2.25
Step-by-step explanation:
y=0.85x, y=0.4x
0.85-0.4=0.45
0.45*5=2.25

How do I find the X and Y intercepts just from this?
Answer:
x-int=6
y-int=30
Step-by-step explanation:
To find the x-intercept, first set F(x)=0, then solve for x.
0=5(x-4)-10
0=5x-20-10
0=5x-30
30=5x
6=x <- the location where y is 0
To find the y-intercept, first set x=0, then solve for F(0).
F(0)=5(0-4)-10
F(0)=-20-10
F(0)=-30 <- the location where x is 0
Answer:
X-intercept: (6, 0)
Y-intercept: (0, -30)
Step-by-step explanation:
DefinitionsThe y-intercept is the point on the graph where it crosses the y-axis, with coordinates of (0, b ). Thus, the corresponding x-coordinate of a y-intercept is 0. The x-intercept is the point on the graph where it crosses the x-axis, with coordinates of (a, 0). Hence, with the x-intercept is the value of x when y = 0. Solutions:Given the function, f(x) = 5(x - 4) - 10:
We could easily find the y-intercept by setting the value of x = 0.
f(0) = 5(0 - 4) - 10
f(0) = 5(- 4) - 10
f(0) = -20 - 10
f(0) = -30
Therefore, the y-intercept of the given function is (0, -30).
Similarly, we can solve for the x-intercept by setting the value of y = 0:
f(x) = 5(x - 4) - 10
0 = 5(x - 4) - 10
Distribute 5 into the parenthesis on the right-hand side of the equation:
0 = 5x - 20 - 10
Combine like terms:
0 = 5x - 30
Add 30 to both sides:
0 + 30 = 5x - 30 + 30
30 = 5x
Divide both sides by 5 to solve for the value of x:
[tex]\mathsf{\frac{30}{5}\:=\:\frac{5x}{5}}[/tex]
x = 6
Therefore, the x-intercept of the function is (6, 0).
Quick Side Note:The given function can be transformed into its slope-intercept form, f(x) = mx + b by distributing 5 into the parenthesis:
f(x) = 5(x - 4) - 10
f(x) = 5x - 20 - 10
f(x) = 5x - 30 ⇒ This is the slope-intercept form, where the slope, m = 5, and the y-intercept, b = -30.

How many solutions does the equation −3x−17=−17−3x have?
Answer:
an infinite number of solutions
Step-by-step explanation:
−3x −17 = −17 −3x
left side = right side TRUE because -3x-17 is the same as -17-3x
we can rearrange the the equation
−3x −17 +17 = −17 +17−3x, add 17 on both sides of the equations
-3x = -3x, divide both sides by (-3)
x = x
Since this equation is always true ( for any number ) we have an infinite number of solutions (since there are is an infinity of numbers.)

Answer:
X and y answer is 45 degrees
Answer:
x = 20, y = 70 degrees.
Step-by-step explanation:
x + y = 90 degrees ( As the large triangle is right-angled).
Now x is the base angle of an isosceles triangle so the small angle that is part of the right angle = x. Call this angle z.
Consider the small triangle which includes 40 degrees:
y + 40 + 90 - z = 180 But as z = x:
y + 130 - x = 180
y - x = 50
Adding the equation to the highlighted equation above we have:
2y = 90 + 50
2y = 140
y = 70 degrees.
So x + 70 = 90
giving x = 20 degrees.
