Step-by-step explanation:
4x-2y = 9 ...1
2x-y = -6 ...2
if ...2 × 2
4x-2y = -12
9 is not equal to -12
9514 1404 393
Answer:
Sydney is 45
Step-by-step explanation:
Let s represent Sydney's age. Then Devaughn's age is (s-14). The total of their ages is ...
s +(s -14) = 76
2s = 90 . . . . . . simplify, add 14
s = 45 . . . . . . . divide by 2
Sydney's age is 45.
___
<em>Check</em>
Devaughn's age is 45 -14 = 31. Their age total is 45 +31 = 76, as required.

Answer:
Step-by-step explanation:
We can see that this graph looks something like the graph of:
f(x) = 1/x^2
But the asymptotes of 1/x^2 are at x = 0, and in this case we can see that the asymptotes are near x = -3.
This may mean that the graph has been horizontally shifted 3 units to the left.
A general way to write an horizontal shift of N units is:
g(x) = f(x + N)
if N is positive, then the shift is to the left, if N is negative, then the shift is to the right.
In this case, we will have;
g(x) = f(x + 3)
And f(x) = 1/x^2
then:
g(x) = 1/(x + 3)^2
Graphing that, we get the graph shown below, that is almost the same as the graph in the image.
