(-2,-1) when you reflect over the x-axis, the number of units from side to side remain the same. However, the point moves the same number of units under the x-axis as it was above it. It was 1 above it so now it is 1 below it.

Hope that helps

If you reflect the point H which is (-2,1) over the x-axis then you would move point H to the x axis line which is one point down, then you would move the point negative one down again over the x axis so the point h1 would be (-2,-1) because it's one away from the X axis if you reflected it

balu736 [363]

Answer:

The answer is 4 years

Step-by-step explanation:

If we use each option to calculate the problem, we get:

125(0.88)^1 = 110

125(0.88)^2 = 96.8

125(0.88)^3 = 85.2

125(0.88)^4 = 74.96

We can see that 74.96 is approximately 75, therefore 4 years is the answer.

What is X in this equation?<br> 3x+55=9x-5<br><br>Please Explain.​
klasskru [66]

Answer:

x = 10

Step-by-step explanation:

3x + 55 = 9x - 5  (add 5 to both sides)

3x + 55 + 5 = 9x - 5 + 5

3x + 60 = 9x  (subtract 3x from both sides)

60 = 9x - 3x

60 = 6x (rearrange)

6x = 60   (divide both sides by 6)

x = 60/6

x = 10

Match the following. 1. the domain set of C = {( 2, 5), (2, 6), (2, 7)} {3, 4, 5, 6} 2. the range set of E = {(3, 3), (4, 4), (5
Artyom0805 [142]

1. The domain set of C = {(2,5),(2,6),(2,7)} is the set of all first elements of the ordered pairs.

Therefore, domain set of C = {2}

2. The range set of E ={(3, 3),(4, 4),(5, 5),(6, 6)} is the set of all second elements of the ordered pairs.

Therefore, range set of E = {3,4,5,6}

3. We need to find the range and domain of F = {(x, y) | x + y = 10}.

Clearly, the domain is the set of all real numbers.

Also, if x is a real number, then 10 - x is also a real number.

We have, x + y = 10

y = 10 - x

So, y is also a real number.

Therefore, range and domain of F = {all real numbers}

4. We need to find the range and domain of P = {(x, y) | y = 3}.

Clearly, the domain is the set of all real numbers.

Since, the y = 3 (the second element of the ordered pair), the range is the singleton set {2}.

Hence, domain = {all real numbers} and range = {y : y = 3}

Imagine you woke up and saw a dinosaur in your backyard. Should you keep it or give it to a zoo? Why?
Drupady [299]
I would carefully record its position and invite palaeontologists from nearby universities and museums to help me excavate it and study it.

Should it turn out to be a new species, I might even have it named after me.

Mind you, since all the rocks in my area are Carboniferous, and thus predate dinosaurs by a large margin, finding one here would make me famous as my discovery would lead to the entire evolutionary history of terrestrial life being rewritten.

One barrel is equal to one cylinder. A cylinder consists of two faces which are circles and everything in between. The area of a circle is pi times radius squared. Using 3.14 as pi, multiply the square of the radius (9) by 3.14. You should get 28.26 . Multiply that because a cylinder consists of TWO circles as faces. That should be 56.52. To find the "wrap" or surface area of the space in between the circle, you need to find the circumference of the circle and multiply it by the height of the barrel (5ft). The circumference of a circle is pi (3.14) times diameter (6). The circumference of the barrel should be 18.84. Multiply that by the height and you should get 94.2. Now, take that number and add it to 56.52. The final answer would be 150.72
