Answer:
undefined because the change in y is zero since they do not change, therefore it is undefined
<u>Answer:</u> The first number is 2, the second number is 3 and the third number is -2
<u>Step-by-step explanation:</u>
Let the first number be 'x', the second number be 'y' and the third number be 'z'
The equations according to the question becomes:
⇒ x + y + z = 3 ....(1)
⇒ x - y + z = -3 ....(2)
⇒ x - z = 1 + y ....(3)
Rearranging equation 3:
⇒ x - y = 1 + z .....(4)
Putting in equation 2:
⇒ 1 + z + z = -3
⇒ 1 + 2z = -3
⇒ z = -2
Putting this value in equation 4 and equation 1, we get:
⇒ x - y = -1
⇒ x + y = 5
Cancelling 'y' by eliminiation method and equation becomes:
⇒ 2x = 4
⇒ x = 2
Putting value of 'x' and 'z' in equation 1:
⇒ 2 + y - 2 = 3
⇒ y = 3
Hence, the first number is 2, the second number is 3 and the third number is -2
Answer:
surface area = perimeter of base x slant height all of it divided by 2 and then add area of base
pb = 4(6)=24 x 9.5 = 228 /2 = 114 + 36 = 150
hope that answers your question :)

Answer:
2:3
Step-by-step explanation:
If you divide 4 by 2 you get 2. If you divided 6 by 2 you get 3. You can't get no more further than that so 2:3 is the simplest ratio.
Hope it helps! :)
