Answer:
Hence the positive numbers are 246, and 41
(246, 41)
Step-by-step explanation:
From the question,
- One positive number is 6 times another number
Let the first positve number be
and the other number be
Hence,
....... (1)
Also,
- The difference between the two numbers is 205
That is,
........(2).
To solve for the two unknowns, substitute the value of in equation (1) into equation (2).
Since,
Then
becomes
Then,
Divide both sides by 5
∴ the value of is 41
Now, substitute the value of y into equation (1) to find
Then,
becomes
∴ the value of is 246
Hence the positive numbers are 246, and 41
(246, 41)

Answer: 1.4 m/s
Explanation: the acceleration equation is a = change in velocity/change in time.
Plug the values in and you get 5.6/4
Divide and get 1.4 m/s
Answer:
Step-by-step explanation:
The problem here is that the question is not clear. In particular, what does "2)" mean?
Reflecting across the x axis is easy. Think of the x axis as a mirror. when you look in a mirror, your image is behind the mirror the same distance you are in front of the mirror. So, to reflect across the x axis, just multiply all the y values of the points by -1. For the reflection part
(-3,4) becomes (-3,-4)
(1,2) becomes (1,-2)
(-2,1) becomes (-2,-1)
Step 2 probably is a translation, but it is not clear what it is - so I cannot help you further.
If you get step 2 straight, the dilation by 3 is achieved by multiplying all the x and y values by 3.
