a)5, b) -2.5, c) -15,d)-2,e)-10
Step-by-step explanation:
True because you can multiply a number to get 40 such as 8 which means 5 was helped to get 40. So that is why 5 is a multiple
Answer:Y = 12
Step-by-step explanation:
Y varies ditectly as x
Y = kx
When y = -4, x = 2
Substitute the value of x and y into Y = kx
-4 = k * 2
Make k the subject of the formula
k = -4/2
k = -2
:. The equation connecting Y and x is
Y = -2x------
When x = -6
Y = -6*-2
Y = 12
