Looking at the two black dots
5 bulbs cost $9
Divide total cost by number of bulbs bought:
9 / 5 = $1.80 per bulb.
10 bulbs cost $18

18 / 10 = $1.80 per bulb
The cost for one bulb is $1.80
Answer: -15yx^2
Step-by-step explanation:
-12x^2 * y -3x^2 * y=
-12(x^2 * y)-3(x^2 * y)=
(-12-3)(x^2 * y)=
-15x^2 * y=-15yx^2
The answer is -3.
If we add positive one/+1 to negative four/-4, we subtract +1 from -4, giving us -3.
