Answer:

±√5 are the solutions to x^2=5

Step-by-step explanation:

Write out x^2=5.  Now enclose each of the two sides in parentheses.  Apply the exponent (1/2) to both sides:

(x^2)^(1/2) = (5)^(1/2)

The left side simplifies to x and the right side to ±√5.

So ±√5 are the solutions to x^2=5.

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.

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.

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.

Equation:

y = x+1

Distance Equation:

sqrt[x^2 + y^2] = 5

===========================

Substitue for "y" and solve for "x":

sqrt[x^2 + (x+1)^2] = 5

x^2 + x^2 + 2x + 1 = 25

2x^2 + 2x -24 = 0

x^2 + x - 12 = 0

Factor:

(x+4)(x-3) = 0

x = 3 miles (eastbound distance)

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.

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:

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).

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.
