Casey is deciding which of two landscapers to hire. Each landscaper charges an hourly rate plus a fee for each job. Casey correctly wrote and solved a system of linear equations by substitution. In his work, he substituted an expression for one variable and solved for the other. This resulted in the equation 5 = 20. What can Casey conclude? One landscaper charges $20 for 5 hours of work. One landscaper’s hourly rate is $15 lower than the other landscaper’s. Both landscapers charge the same hourly rate and the same fee per job. Both landscapers charge the same hourly rate, but not the same fee per job.

Answer:

1 and 4 parallel lines are straight

Step-by-step explanation:

Let me = slope

m = (18 - (-2))/(4 - 0)

m = 20/4

m = 5

We now plug slope 5 and one of the given points into the point-slope formula.

y - y_1 = m(x - x_1)

y - 18 = 5(x - 4)

y - 18 = 5x - 20

y = 5x - 20 + 18

y = 5x - 2

Answer:

$0.76

Step-by-step explanation:

3.79+2.57+5.8=12.16

12.16 x 0.0625=0.76

To solve this, you have to add all the prices together and then convert the percentage into a number so that you can multiply it by the total sales. You end up with 0.76 cents as the taxes for Akio's Purchase.You convert the percentage by moving it backward 2 decimal places.

Step-by-step explanation:

3x-9=2x+73

3x-2x=73+9

x=82

Answer:

x = 83

Step-by-step explanation:

3x-9 / 2 = x + 37

1. multiply both sides by 2 to get rid of the fraction

3x - 9 = 2x + 74

2. move the variable to one side and the numbers to another side

3x - 2x = 74 + 9

x = 83

Answer:

376.52 is the volume of the composite figure.

Step-by-step explanation:

Let's break this into two shapes.

A rectangular prism and a hemisphere

Volume Formula for rectangular prism: l • h • w

Volume Formula for hemisphere: (2/3)πr^3

l • h • w

10 • 4 • 8

40 • 8

320

Rectangular Prism: 320

(2/3)πr^3

2/3(3)^3

2/3(3.14)(27)

2.09333333333(27)

56.52

Hemisphere: 56.52

320 + 56.52 = 376.52

The volume of the composite figure is 376.52  [tex]cm^{3}[/tex].

The total space occupied by a hemisphere in a 3-dimensional region is called its volume. Geometrically a hemisphere is an exact half of a sphere.

Volume of hemisphere = [tex]\frac{2}{3} \pi r^{3}[/tex]

The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.

Volume of cuboid = Length × Width × Height

Given

Radius of hemisphere r = 3

Volume of hemisphere = [tex]\frac{2}{3} \pi r^{3}[/tex]

Volume of hemisphere V1= [tex]\frac{2}{3} \pi r^{3}[/tex]

= [tex]\frac{2}{3} .(3.14).(3)^{3}[/tex]

= 56.52 [tex]cm^{3}[/tex]

Volume of cuboid V2 = Length × Width × Height

= 10 × 8 × 4

= 320 [tex]cm^{3}[/tex]

The volume of the composite figure V = V1 + V2

V =  56.52 +  320

V = 376.52  [tex]cm^{3}[/tex]

Hence, the volume of the composite figure is 376.52  [tex]cm^{3}[/tex].

IM LOOKING FOR THE ANSWER TO LOL

Step-by-step explanation:

The lines y= 3x + 2 and y= 3x -3 are parallel because the slope of the lines is an equal option (A) is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The equation of the lines:

y = 3x + 2 and y = 3x - 3

The slope of the line:

y = 3x + 2

y = mx + c

m = 3

The slope of the line:

y = 3x - 3

y = MX + C

M = 3

m = M

The slopes of the line are the same.

Thus, the lines y= 3x + 2 and y= 3x -3 are parallel because the slope of the lines is an equal option (A) is correct.

Answer:

Answer:

Option 4: 45 units is the correct answer

Step-by-step explanation:

Let [tex]P_1[/tex] be the perimeter of Pentagon and

Let P2 be the perimeter of Triangle

So,

[tex]P_1 = 5(\frac{1}{2}x-1)\\P_2 = 3(x-5)[/tex]

In order to find the perimeter of each figure we have to put both the expressions equal so that the value of x can be found and then perimeter.

So,

[tex]P_1 = P_2\\5(\frac{1}{2}x-1) = 3(x-5)\\\frac{5}{2}x-5 = 3x-15\\\frac{5}{2}x-3x = -15+5\\\frac{5x-6x}{2} = -10\\-\frac{x}{2} = -10\\-x = -10 * 2\\-x = -20\\x = 20[/tex]

Putting x = 20 in 2nd perimeter

[tex]P_2 = 3(x-5) \\= 3(20-5)\\= 3(15)\\=45[/tex]

As both the perimeters are same, the perimeter of pentagon will also be 45 units.

Hence,

Option 4: 45 units is the correct answer

Answer:

y=120x

Step-by-step explanation:

You can just divide all of the points (y/x) and they all equal to 120. And when you add it to the equation its y=120x

The correct option is,

⇒ Since the function is even, the outputs of a negative x-value and a positive x-value are the same.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Since, We know that;

A function is "even" when f(x) = f(−x) for all x.

Now, Geometrically speaking, the graph face of an even function is symmetric with respect to the y-axis, meaning that its graph remains unchanged after reflection about the y-axis.

So, If point (6, 8) is one the points on the graph of f(x),

Then, f (6) = 8

And, since function is even, you can state that;

⇒ f(-6) = f(6) = 8.

This means that point (-6,8) must also be a point on the graph. Geometrically it means that the output of a negative x-value and its opposite is the same.

Thus, The correct option is,

⇒ Since the function is even, the outputs of a negative x-value and a positive x-value are the same.

Answer:

B.

Step-by-step explanation:

Any point in the highlighted (red) region will be in our solution set.

Note that our line is dotted. Thus, any points on the line is not in our solution set.

So, we can simply go through each point and check.

A is on the line. So, A is not a solution.

B is within the red region. Hence, B is our solution.

C is on the line. So, C is not a solution.

And D is not in the red region. So, D is not a solution.

Therefore, our answer is B.

The required simplified solution of the given expression is (√2 + √5).

Given that, to simplify the expression √3(√6+√15).

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
= √3(√6+√15)
= √3×√6 + √3 ×√15
= √3×√3×2 + √3 ×√3×5
