The Venn diagram shows the number of patients seen at a pediatrician’s office in one week for colds, C, ear infections, E, and a
llergies, A.
Circles C, E, and A overlap. Circle C contains 4, circle E contains 9, and circle A contains 15. The overlap of C and A contains 2, the overlap of C and E contains 10, and the overlap of E and A contains 3. The overlap of the 3 circles contains 1. Number 5 is on the outside of the circles.
How many patients had allergies or ear infections, but not both?

Answer:
Step-by-step explanation:
To find the slope of the perpendicular line, we must first find the slope of the given line.
This can be done by rearranging the equation into the slope intercept form.
2x +3y= -3
3y= -2x -3
y= -⅔x -1
Thus, the slope of the given line is -⅔.
The slope of the perpendicular line is the negative reciprocal of the given line.
Slope of perpendicular line
What is slope-intercept form?
- y= mx +c, where m is the slope and c is the y-intercept
- This can be achieved by making y the subject of formula
Negative reciprocal
- The reciprocal of m is
- The negative reciprocal of m is
Negative reciprocal of -⅔
