Answer:
420
Step-by-step explanation:
Each of the 7 appetizers can be paired with one of 10 entrees, and each entree can be paired with one of 6 desserts. So the number of combinations is:
7 × 10 × 6 = 420
Y = mx+b m is slope x is a point you choose and b is the y intercept.
Answer:
24.3
Step-by-step explanation:
18/20 = x/20 (similar triangles)
The cross product of two vectors gives a third vector

that is orthogonal to the first two.

Normalize this vector by dividing it by its norm:

To get another vector orthogonal to the first two, you can just change the sign and use

.
Answer:
The coordinates of the image of point A (2, -7) are A'(-1,-2).
Step-by-step explanation:
Note: The sign is missing between y and 5 in the rule of transitional.
Consider the rule of translation is

We need to find the image of point A (2, -7).
Substitute x=2 and y=-7 in the above rule.


Therefore, the coordinates of the image of point A (2, -7) are A'(-1,-2).
