Answer:
(-6,2)
Step-by-step explanation:
<u>Substitution</u>
Substitute x = -6 from the first equation in the second equation.
Normally, we have to substitute either x-term or y-term in one of the equation to get another term. For this situation, we already know the value of x so It is not necessary to substitute the y-value.
<u>Answer</u><u> </u><u>Check</u>
We have to check the answer to make sure that we have got the right answer.
We can check the answer by substituting both x-value and y-value in the equation.
Substitute x = -6 and y = 2 in the equation.
The equation is true. Therefore, our answer is (-6,2)
Answer:
no triangle can be formed with the given values (i.e 0 triangle).
Step-by-step explanation:
Given;
length of side a, = 10
length of side b, = 40
angle A, = 30°
Apply sine rule to determine the angle of the second side (B);
The maximum sine function is 1, there is no sine function that will be equal to 2, so there is no triangle that can be formed with the given values.

Answer:</h2>
<em>x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.</em>
<h2>
Explanation:</h2>
Here we have the function:
that models the profit in dollars, where x is the number of memberships sold. In order to get the zeros we'll use the quadratic formula:
So the zeros are:
The zeros occurs when , so we can conclude that at those points there is no any profit.
In conclusion:
<em>x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.</em>
