Answer:

C

Step-by-step explanation:

We will graph 3^{-x}  and  6^{-x}  and find <em>WHERE in the x-axis,  3^{-x}  is greater than  6^{-x}.</em>

<em />

Attached is the graph of both the functions. RED color graph is of  3^{-x}  and BLUE color graph is of  6^{-x}.

So, <u>WHICH WHERE IN X-AXIS IS THE RED GRAPH "ABOVE" THE BLUE GRAPH?</u>

We can clearly see that this occurs when x > 0.

Hence, C is the correct answer.

The winery sold 81 cases of wine this week. If twice
nydimaria [60]

Answer:

Option (C)

Step-by-step explanation:

Let the red cases sold = r

and the number of white cases sold = w

Total number of cases sold by the winery = 81

r + w = 81 -------(1)

If number of red cases sold is twice of white cases sold,

r = 2w ------- (2)

By substituting the value of r from equation (2) to equation (1),

2w + w = 81

3w = 81

w = 27 cases

From equation (1),

r + 27 = 81

r = 54 cases

Therefore, number of white cases sold are 27 cases

Option (C) is he answer.

Given two similar triangles, how does one use proportions to find the lengths of one of the sides of one of the triangles? Answe

➷ As they are similar triangles, there will be a scale factor between them. You may be given one pair of values on the triangle. Divide the larger value by the smaller value in order to find the scale factor between the triangles. For example, if the larger triangle has a length of 6cm and the smaller triangle has a length of 3cm, the scale factor would be 2. You would then multiply the given side by the scale factor to get the length.
