<u>The given expressions 7+ 7x ; 7 x + 1/7 are not equivalent or equal </u>
<u>to each other </u>
<u />
<u>Step-by-step explanation:</u>
Let us firstly assume that 7 + 7x is equivalent ( to 7(x + 1/7) so that means
7 + 7x = 7(x + 1/7)
7 + 7x = 7x + 7(1/7)
7 + 7x = 7x + 1
7x + 7 = 7x + 1
Now, subtracting 7x from both sides, we get:
7x - 7x + 7 = 7x - 7x + 1
(7 - 7)x + 7 = (7 - 7)x + 1
(0)x + 7 = (0)x + 1 thus their occurs a false statement:
7 = 1 ( we know, 7 >1)
Thus we can say that
<u>7 + 7x is NOT equivalent to 7(x + 1/7)</u>
Answer:
Building and solving an equation, it is found that the coordinates are: (9,0).
We are given two points: A(-9,3) and B(21, -2).
We also want point C(x,y).
C is 3/5 of the way from A to B, thus:
This is used to find both the x-coordinate and the y-coordinate of C.
First, the x-coordinate, considering .
Then we get 9,0
