Okay so in school I am doing this litterly right now. So all u have to do is when it is a different sign you subtract, when it is the same you add. So think of it as, Different/Difference and Same/Sum. when the sign is different u find the difference and when u have the same sign you find the sum.
Example 1: -3+8= 5
Use the same sign as the largest number
Example 2: 5+(-10)= -5
Hopefully This helped! It is easier then you may think once you get the hang of it! ( You get the hang of it REALLY fast ) :)
15 cups, I am pretty sure, i might be under thinking it
F(-3)=(-3)2 - 1 / -3 + 4
f(-3)= -6 -1 / -3 + 4
f(-3)= -7/1
f(-3)=-7

Answer:
(3 , 2.5)
Step-by-step explanation:
.5x + y = 4
y = .5x+1
.5x + (.5x + 1) = 4
x + 1 = 4
x = 3
y = .5(3)+1
y = 1.5 + 1
y = 2.5
