2. 2 Students test results in three subjects; Mathematics, Biology and Kiswahili reveals the following, 20 passed Kiswahili, 5 passed all the three subjects, 12 passed Mathematics and Biology; 16 passed Mathematics and Kiswahili. Each student passed at least 2 subjects. (a) Draw a well labelled Venn diagram to represent the sets. (b) How many students passed Biology and Kiswahili? (c) How many students did the test? 3. 2517

you need to show us the graph.

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
