Step-by-step explanation:
Answer:
By graphing the line, we have the equation y =
Step-by-step explanation:
What this question is asking us is to find the equation of the line with the value of the slope given in the question and also passing through the point in the question
For a straight line, the general equation can be represented as
y = mx + c
where m is the slope of the line and c is the y intercept. From the question, we have the value of the slope, what we have left to find is the value of the intercept. We find this by inserting the x, y and the slope value into the general equation of a straight line.
We have;
-3 = 3/4(2) + c
c = -3 - 6/4
c = -3-1.5 = -4.5
Thus, the equation of the line is;
y =
We have to choose 3 teachers from a group of 7 teachers, then, the amount of combinations is given by
We have to choose 3 students from a group of 8 students, then, the amount of combinations is given by
Since we have to choose a committee simultaneously formed by 3 teachers and 3 students, we want the intersection of those combinations, which is given by their product
The formula for a combination is given by
Then, we have
26-22x is the correct answer
