Tell whether the ordered pair is a solution of the equation. y = x - 5; (6, 11)​

Answers

Answer:

Not a solution

Step-by-step explanation:

y=x-5

Plug in the point (6,11)

11=6-5

11=1

11≠1

Because the left side of the equation and the right side aren't equal, the ordered pair (6,11) is not a solution to the equation y=x-5.

I hope this helps!

Answer:

It isn't a solution of the equation.

Step-by-step explanation:

(x, y) = (6, 11)

You replace the values ok the equation:

11=6-5

11=1 Which is FALSE so it isn't a solution of the equation.

I need help and please give me an understandable answer because I need to go to bed right now. I used 31 and 40 feet and none of them worked

Answers

Answer:

35 feet

Step-by-step explanation:

We'll begin by calculating the resultant for you and your friend.

For you:

R² = 12² + 9²

R² = 144 + 81

R² = 225

Take the square root of both side

R = √225

R = 15 feet

For your friend:

R² = 16² + 12²

R² = 256 + 144

R² = 400

Take the square root of both side

R = √400

R = 20 feet

Finally, we shall determine the distance between you and your friend.

The distance between you and your friend is obtained by adding your resultant and that of your friend together i.e

You resultant = 15 feet

Your friend's resultant = 20 feet

Distance between you and your friend = 15 + 20 = 35 feet.

Therefore, you threw the baseball 35 feet away from your friend.

Need help ASAP please--about estimate. which answer is correct. Please give me an opinion. Three students were asked to use estimation strategies to find a reasonable solution to this question: Ricky had 26 stickers before buying 7 from the store. Then he gave 8 to his sister. Estimate how many stickers he has left. From the choices below, select the student with the most reasonable solution.
a) Student A: Ricky has around 45 stickers left. Round 26 stickers to 40, 7 bought to 10, and 8 given to 5. Add 40 + 10 to get 50. Then subtract 50 − 5 to get the estimated answer of 45.
b) Student B: Ricky has around 30 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 20. Add the 20 to the leftover 20 to get 40. Round 8 given to 10. Then subtract 40 − 10 to get the estimated answer of 30.
c) Student C: Ricky has around 10 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 10. Add the 10 to the leftover 10 to get 20. Round 8 given to 10. Then subtract 20 − 10 to get the estimated answer of 10.

tmara is making a medium length necklace. write an expression that shows how nuch it will cost tamara for the chain,pendant,and b beads that cost $0.25 each.Then find the total cost of the necklace if tamara uses 30 beads.

Answers

Answer:

1/4(n), $7.50

Step-by-step explanation:

Expanded: cost = 0.25 * chains + 0.25 * pendants + 0.25 * beads

Simplified: c = (1/4)(total number of items)

Expression only: 1/4n where n = # chains + # pendants + # beads purchased

Total cost of 30 beads = 1/4(30) = 7.5 = $7.50

What is a function rule?

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 2x + 1

The inverse of the function is calculated by taking the x coordinate and replacing it with y

So , the function now becomes

x = 2y + 1

On simplifying , we get

Subtracting 1 on both sides , we get

2y = x - 1

Divide by 2 on both sides , we get

y = ( x - 1 ) / 2

Now , replacing y with x , we get

h ( x ) = ( x - 1 ) / 2

h ( x ) = ( 1/2 )x - ( 1/2 )

Hence , the inverse of the function is h ( x ) = ( x - 1 ) / 2

what is the measure of angle b​

Answers

Answer:

34

Step-by-step explanation:

A triangle will add up to a degree of 180, so if you add those 2 angles then subtract it from 180 you will get the answer. So, 115+31=146 then 180-146=34

So the answer is 34

Answer:

b = 34 degrees

Step-by-step explanation:

*triangles have an interior angle of 180 degrees

to find b, take the known angles (115 and 31) add them together and subtract the sum from 180:

⇒ 180 - (115 + 31)

solve:

⇒ 180 - 146 = 34

b = 34

Answer:

1. x = 462.30m

2. c

Step-by-step explanation:

1. Let "x" represent how much Samantha earns, and "m" represent how many months she has worked.

Because she makes $462.30 per month, if we multiply that by "m" then we will get x.

2. Kyle spend $44 on four sweaters total, which would make the total cost be evenly distributed into 4 sections.
