Answer:
15 students celebrate both holidays
Step-by-step explanation:
Let the number of students that celebrate both be x
By set notation, we add up individual sides as follows to give the number of values on the universal set
Mathematically, that will be;
50 = (29-x) + (36-x) + x
50 = 29-x + 36-x + x
50 = 65-x
x = 65-50
x = 15
If this is a slope question then:
We know that the formula for slope is:
y = mx + b ( M being slope, X being the x- intercept and y being the y-intercept)
So if the question asks to write an equation of the line with a x-intercept of -5 and a y- intercept of 15.
So now you substitute -5 for the x-intercept, and 15 for the y-intercept:
So now it's
y = 15m + -5
The m stays since there's no value for m.
So the final answer is: y = 15m + -5
