Yes, it's in scientific notation.
The 1st graph has vertex in (-3, -3) which can be translated into
Horizontal shift left 3
Vertical shift down 3
Other than that, the graph shows y=x^2 so it wasn't compressed or stretched
The 2nd graph has vertex in (0, 0) which mean there is no vertical and horizontal shift. But the graph is facing down and it was slimmer than y=x^2 graph. When x=1, the result is y=3 which was 3 times more than it supposed to be.
The graph must be:
Reflection across x-axis
Vertical stretch of 3
The 3rd graph has vertex in (3, -3) which can be translated into
Horizontal shift right 3
Vertical shift down 3
Same as the 1st graph, the 3rd graph shows y=x^2 so it wasn't compressed or stretched.
For the first month, the membership fee deducted = $15
So, -15(1) will represent this situation.
Similarly, for the second, third, fourth months, the expressions will be:
-15(2), -15(3), -15(4) and so on.
Hence, if t represents the number of months, then -15t will represent ash's art club membership being deducted every month for a year.
Answer:
2x - 3y + 8
Step-by-step explanation:
If you combine like terms
(In this case "y" and "-4y")
You get "-3y"
The rest of the equation stays the same, as there are no more like terms.
Therefore the answer is the D.
