Answer: The first number is 4

Explanation: Since the sum of the two numbers is ten, x + y = 10

Also, since the difference of the two numbers is two, then x - y = 2

Since x - y = 2, another way to write that is x = y + 2 and since x is exactly the same as y + 2, we can plug in "y + 2" in place of x in the first equation (x + y = 10) to get (y + 2) + y = 10. Then we solve this equation by combining like-terms.

2y + 2 = 10

2y = 8

y = 4

Since x = y + 2, x = 4 + 2 or x = 6

I hope this helped you!

Answer:

x = -7

y = 9

Step-by-step explanation:

x + y = 2

x - y = -16

substitute '2-x' for 'y'

x - (2-x) = -16

x - 2 + x = -16

2x - 2 = -16

2x = -14

x = -7

-7 + y = 2

y = 9

Answer:

\boxed{\sf{4}}}

Step-by-step explanation:

Use a slope form.

<u>Slope:</u>

\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run}  }

y₂ = (17)

y₁ = (1)

x₂ = (2)

x₁ = (-2)

Then, rewrite the problem.

Solve.

\sf{\dfrac{17-1}{2-(-2)}=\dfrac{16}{4}=\dfrac{16\div4}{4\div4}=\dfrac{4}{1}=\boxed{\sf{4}    }

Therefore, the slope is 4, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.

Is 2,750 a reasonable answer for 917 x 33? Explain.
vovangra [49]

No, 2750 is a sadly unreasonable estimate. 917 is almost 1,000 . 33 times as much is around 30,000 . 2,750 is less than 3,000 .

Step-by-step explanation:

so it will be 3,0261

galben [10]

I don’t have a very detailed explanation, however the answer should be “A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left”.

You can clearly see a 90° angle here, it’s obvious. Also, the polygon switch counterclockwise. so, you can see.

hope I helped ^^
