Answer:

Step-by-step explanation:
slope (rise over run) choose 2 points that are easy to figure out. Count up and over to get the slope
(0,3) and (4,4)
3 to 4 is 1
0 to 4 is 4
slope is 1/4
y intercept is b- so +3
y=
Answer:

Step-by-step explanation:



<u />
13 × 9w = 13 × 
117w = 5w - 6 + 13
117w = 5w + 7
117w - 5w = 5w - 5w + 7
112w = 7
112w ÷ 112 = 7 ÷ 112

The cardinality of the union between two sets is given by

In fact, if an element is in both A and B, it is counted in both N(A) and N(B), so we're counting it twice. By subtracting the cardinality of the interserction, we're taking back one of these "extra-counted" element, and the count is correct. In your case, the numbers are

This means that the two sets cover, without repetitions, 43 of the 66 elements in the sets. So, there are

elements which are in neither A nor B
The answer to the solution is X+3<19-x.
