Please help me out please
Arte-miy333 [17]

Answer:

B

Step-by-step explanation:

The red graph is a horizontal translation of 5 units left, followed by a reflection in the x- axis, of the black graph.

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then shift to the left of a units

• If a < 0 then shift to the right of a units

Here the graph is shifted 5 units to the left, thus

f(x) → f(x + 5)

Under a reflection in the x- axis

a point (x, y ) → (x, - y )

Note the y- coordinate of the image is the negative of the original

Note that \frac{y}{-1} = - y, thus

The equation of the red graph is

\frac{y}{-1} = f(x + 5) → B

sergejj [24]

Answer:

24.

Step-by-step explanation:

So you need to fine 30% of 80.

I did the following method:

-Break it down, and do, 80 -/- 10 which is 8, now you have 10%, and you need to find 30, times your 10% by 3, so 24.

-Therefore, 24 out of 80 rides at the amusement park are water-related.


Hope this helps!
