0= -3x+9
-9=-3x
3=x

Final answer: x=3

There is only one zero because it is linear, and can therefore only cross the x axis once.

Find a ·<br> b. |a| = 60, |b| = 30, the angle between a and b is 3π/4.
Delvig [45]
The dot product is used to determine the magnitude of the resultant vector of two component vectors. It is expressed as a·b. It does not literally mean that you multiply their values. Instead, you multiply their matrices. However, since we cannot find matrices, let's just find the resultant vector through theorems involving triangles. By cosine law:

R = √[a² + b² - 2abcos(3π/4)]
R = √[60² + 30² - 2*60*30*cos(3π/4)]
R = 83.94

Thus, a·b = 83.94

kramer

Answer:

The probability that a car chosen at random is not red is 75%.

Step-by-step explanation:

Given that a used car dealer sells SUVs and cars, and of all the vehicles, 60% are cars, and of all the vehicles, 15% are red cars, to determine what is the probability that a car chosen at random is not red you must perform the following calculation:

60 = 100

15 = X

15 x 100/60 = X

25 = X

100 - 25 = 75

Therefore, the probability that a car chosen at random is not red is 75%.
