Whts X+y x 9 +3 +4 ?
babunello [35]

Expression simplified: x+9y+7

Step-by-step explanation:

The expression that we have in this problem is:

x+y\cdot 9 +3 +4

The first type of operation that we have to solve in such expression are multiplication/division.

In this expression, there is only one multiplication, that is:

y\cdot 9 = 9y

So we can rewrite the expression as

x+9y+3+4

Now we can evaluate the sum of the similar terms: in this case, similar terms are only 3 and 4, and their sum is

3+4=7

Therefore, the expression can be rewritten as

x+9y+7

A television game show begins with 20 contestants. Each week, the players vote 2 contestants off the show. What is the rate of c
nadya68 [22]

Using a linear function, it is found that the rate of change in this problem situation is of -2 contestants per week.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Considering the situation described, the number of participants after n weeks is given by:

N(n) = 20 - 2n.

The slope is of -2, hence the rate of change in this problem situation is of -2 contestants per week.

If the point (x,square root 3/2) is on the unit circle, what. is x?
galina1969 [7]

Answer:

x=\pm\frac{1}{2}

Step-by-step explanation:

On a unit circle, (x,y)=(\cos\theta,\sin\theta), so \sin\theta=\frac{\sqrt{3}}{2} in this case. If you look at the attached circle, the only time that the y-coordinate is \frac{\sqrt{3}}{2} is when x=-\frac{1}{2} and x=\frac{1}{2}, which correspond to angles of \theta=\frac{2\pi}{3} and \theta=\frac{\pi}{3} respectively
