Okay so I'm guessing that they are two different formulas the f(x)= 3x and the f(x)= -5x-2. If that's is true then you would just have to plug in -2 to the x's. So then it would be f(x)= 3(-2) which if you solve it would give you f(x)= -6 and for the second one it would be f(x)= -5(-2)-2 so then you would solve for it and get f(x)= 8.
O=2a+2,
o/2-a/2=4 this is your system of equations,
It you wish to solve for apples, then simply substitute o from the first equation into the second equation...
(2a+2)/2-a/2=4 multiply both sides of the equation by 2
2a+2-a=8 combine like terms on the left side
a+2=8 subtract 2 from both sides
a=6
So Javier has 6 apples in the basket.
Answer:
(−2)×5<(−20)
Step-by-step explanation:
