So to find the answer you want to isolate the y. So the first thing you want to do is to move everything to the opposite side of the = sign. You start by adding 10 to both sides.
10+ 5y -10 = -25 +10
5y = -15.
the tens cancel out on the left side and on the right you get left with -15/
Since y is being multiplied by 5 you always want to do the opposite so you divide by 5.
5y/5 = -15/5
y = -3
It's hard to explain but you just have to remember that what you do to one side you must do to the other to keep the equation balanced.
assuming that 0 apples costs 0 dollars
and 16 apples costs $8
so we have the points
(0,0) and (16,8) in form (x,y)
graph below
-10 belongs to integers, rational numbers, and real numbers.
Answer:
4v-6.3w+9.8
Step-by-step explanation:
If you distribute the negative sign (same as distributing -1), then you get -(-4v) + (-6.3w) - (-(9.8))
Basically it's switching the signs
Hope that helped :)
