Answer: (-2, -2)

Step-by-step explanation:

Reflection over the x-axis: (x, y) → (x, -y)

(-2, 2) → (-2, -2)

x would remain the same but the y would turn negative since we're reflecting over the x-axis. The x never changes in this situation but since we're flipping it over the x-axis, they y has to be negative.

Hope this helps!

25.74- 8.58=x/4.29

Responder:

x = 40

y = 120

z = 80

Explicación paso a paso:

Número dividido = 240

Las 3 partes:

x, y, z

y = 3x

Z = 3x - 40

x + y + z = 240

x + 3x + 3x - 40 = 240

7x - 40 = 240

7x = 240 + 40

7x = 280

x = 280/7

x = 40

y = 3 (40)

y = 120

z = 3x - 40

z = 3 (40) - 40

z = 120 - 40

z = 80

Step-by-step explanation:

company g is charging 10 per  hour and in the graph when it is zero hours it shows the base charge which is 25 but in addition when you add an hour if you subtract that amount minus the flat amount 25 you will get 7 and will continue to do so as you continue across the graph 10-7 equals 3

Answer:

2 years = 1252.80 5 years =1332

Step-by-step explanation:

1,200 x 2.2% = 26.4

26.40 x 2 = 52.80

1200 + 52.80 = 1252.80

26.40 x 5 =132

1200 + 132 =1332

Answer:

7.4 % is percent error

Step-by-step explanation:

https://brainly.com/question/21689164

The percent of error is 7.4%. The correct option is B.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Estimated value: 231

Actual value: 215

To find the percentage:

First, the value,

= 231 - 215

= 16

Now,

let n be the percentage.

So,

16 = n x 215/100

n = 1600/215

n = 7.4%

Therefore, 7.4% is the error.

Answer:

Step-by-step explanation:

Area of Alfred's land = (x²- 25)

Factors of given expression = (x - 5)(x + 5)

Therefore, Alfred's land will have the dimensions (x - 5) and (x + 5).

Area of his neighbor's land = x² + 3x + 2

Factors of the given expression = x² + 2x + x + 2

                                                     = x(x + 2) + 1(x + 2)

                                                     = (x + 1)(x + 2)

Therefore, dimensions of Grace land will be (x + 1) and (x + 2).

Answer:

2nd friend heading west

Step-by-step explanation:

This is actually pretty easy to explain.

You and a friend are near a tree and decide to walk away from it. At the beggining you walked 15 yards and your friend too, and then, there's the turn of event. You walked 8 yards toward north east, and your friend 8 yards towards south west.

The key to know which is further from the tree is the angle of turning of both. We need to calculate the component in x from both persons, and then, add it to the previous 15 yards. This way we will know who is further.

Let's begin with the 1°, the one who's heading east:

X = 15 + 8 cos45° = 20.66 yards

Now the friend heading west:

X = 15 + 8 cos40° = 21.13 yards

With these results we can conclude that the 2nd friend is further from the tree.

Answer:

16 million for the first year

Step by step explanation:

Let x be the first year's sales

Let x+ 3 be the second year's sales.. since they sold 3 million more in

the second than on the first.

Let 2(x+3) be the third year's sales... since they are double the second

year's sales.

Using the Distributive Property, this becomes 2x+6..

Now, 2x+6= 38

-6 -6 Subtract 6 from both sides

2x = 32 Divide both sides by 2

x= 16

So the sales for the first year are 16 millions, 19 on the second, and 38 on the third.

Answer: 11:15am

Step-by-step explanation:

Since it It takes 5 minutes to get to the airport, and Carter wants to be at the airport 2 hours and 45 minutes before his flight leaves. This means he will use about (2 hours 45 minutes + 5 minutes) = 2 hours 50 minutes before his flight leaves.

We would then subtract 2 hours 50 minutes from the time that his flight leaves. This will be:

= 2:05pm - 2hours 50 minutes

= 11:15am.

He will have to leave latest 11:15am

[tex]\boxed {\boxed {\sf d= 13}}[/tex]

Step-by-step explanation:

Distance can be calculated using this formula:

[tex]d= \sqrt {(x_2-x_1)+(y_2-y_1)[/tex]

where (x₁, y₁) and (x₂, y₂) are the points. We are given the points (6, -9) and (1, 3). Therefore:

[tex]x_1= 6\\y_1= -9 \\x_2= 1\\y_2=3[/tex]

Substitute the values into the formula.

[tex]d= \sqrt {(1-6)^2+(3--9)^2[/tex]

Solve inside the parentheses.

[tex]d= \sqrt{(-5)^2 + (12)^2[/tex]

Solve the exponents.

[tex]d= \sqrt { 25+144}[/tex]

Add and take the square root.

[tex]d=\sqrt{169} \\d= 13[/tex]

The distance is 13.
