Answer:
4 students
Step-by-step explanation:
As shown in the diagram, let U=[The total number of students questioned]

A=[Those who liked peanut butter ]

B=[Those who liked jam ]

x = those who like both peanut butter and jam.
Also 6 liked neither peanut butter nor jam.
From the diagram we can write the mathematical equation as follow and solve for x


We add x and subtract 30 to both sides.


Therefore 4 students like both peanut butter and jam.

Answer:
y +3 = -2(x +4)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
For your given point and slope, this is ...
y -(-3) = -2(x -(-4))
y +3 = -2(x +4)
