Please help and write a proper answer I really need it. Thanks.

Answer:

x=10-y

Step-by-step explanation:

Answer:

choose to places and with this formula, you can find it easily;

(y_2 - y_1)/(x_2 - x_1)

first place can be (1, 3) and the second can be (2,5):

5-3/2-1 =2

and it would be 2

the Anser un the Fire one is B and the answer on the 2nd one is A

Answer:

Answer:

42

Step-by-step explanation:

Opposite sides of a parallelogram are congruent

You need to find the distance between Q(6, 6) and R(1, -6) using the distance formula.  

PS = QR = [tex]\sqrt{(6 - 1)^{2} + (6 + 6)^{2} }[/tex]

     = [tex]\sqrt{5^{2} + 12^{2} } = \sqrt{25 + 144} = \sqrt{169} = 13[/tex]

PQ = SR = 8

Perimeter = 13 + 13 + 8 + 8 = 42

Answer:

25.13 m/s

Step-by-step explanation:

Linear velocity = Distance / time

The distance = Circumference of turbine = 2πr

Radius, r = 40 m

Circumference= 2 * π * 40 = 251.327

The linear velocity is thus :

Circumference / time

= 251.327m / 10s

= 25.13 m/s

Answer:

When x < 0 (Option 1)

Step-by-step explanation:

The answer to your question would be Option 1, or when x < 0. When you create a table with f(x) and g(x), they're only ever equal when x = 0, which is when f(x) and g(x) both equal 1. When the numbers go into negatives for each equation, f(x) becomes exponentially bigger. Making f(x) > g(x) true when x < 0.

is this the full question?

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Yoy get A by combining like terms.

Answer:

Is 10B and you get like 1000

Answer:

you get like 1000

Answer:

to find the value of x have to know that they would all add up to 180 degrees. so subtract 98 from 180. then you would have to find the angel of the part on the left.

Step-by-step explanation:

Answer:

X = 41

Step-by-step explanation:

this triangle is isosceles triangle, so

X + X + 98 = 180 ( being triangle)

2X + 98 = 180

2X = 82

therefore : X = 41

Answer:

the only one that would make sense is D because it says 1 pair of parallel and the left one only has one pair

Step-by-step explanation:

(you might want to ask your teacher though because its kind of misleading)

Answer:

x = 10

Step-by-step explanation:

Since both equations give y in terms of x, equate the right sides

3x - 28 = - 2x + 22 ( add 2x to both sides )

5x - 28 = 22 ( add 28 to both sides )

5x = 50 ( divide both sides by 5 )

x = 10

Answer:

B.

Step-by-step explanation:

So, lets remember a few things first.

#1: The formula for finding the answer is A^2+B^2=C^2

#2: A is the opposite side, B is the adjacent side, and C is the hypotenouse side.

Now lets plug in what we already know, and see if we canf igure out the annswer:

A^2+12^2=13^2

Now I am going to stop us here. This is your equation that will find the answer. In your question, they use x^2, A^2 is a variable you can use instead. But looking at this, answer B and my equation I wrote above are exactly the same.

If you want, here is how I further solved it, this might give you a better grasp on what to do for future problems:

Ok, not  too bad, the A is the unkown value, which is the opposite side.

Now, how do we figure this out? Well, we just need to sovle for A.

To do this, lets clean up our equation by first sqauring all the values(except for the unkown):

A^2+144=169

Ok, that looks better, now lets just subtract the adjeacent side(b), which is 144, from the hypotenouse side(c), which is 169.

This will now look like:

A^2=25(169-144=25)

Ok, just one more step to go. Just square root both sides of the equation, this way, we will get ride of the ^2 on A(opposite side), and get A alone.

([tex]\sqrt{A^2}=A[/tex])=([tex]\sqrt{25}=5[/tex])

A=5

This is your answer.

Answer: 20.989353895 or round it up to 21

Step-by-step explanation:

If we want to find a diameter of a circle and given a circumference, we divide the circumference by pi

so 65.94 divide by pi = 20.989353895

Answer: 1/4

Step-by-step explanation: Take point (1,1) put the rise (2) over the run (8) and then simplify.

Answer:

Option 2, 3, and 4 are correct.

Step-by-step explanation:

Answer: x=120°

Step-by-step explanation:

What you are looking for is the value of the exterior angle of the regular polygon.

For a n-sided regular polygon, the external angle is given by the formula 360°/n.

Because the shape in this example is a regular triangle, the value of n is 3.

360°/n

=360°/3

=120°

Therefore, x=120°

Answer:

yes

Step-by-step explanation:

Answer:

30%

Step-by-step explanation:

3/10=30/100 and 30/100 is the same as 30%

because %'s mean out of 100 so 30% means 30 out of 100 which can be simplified to 3 out of 10 or 3/10 (so its all equal)

Answer:

3%
