Ice is a solid form of water. So then the form of ice would be solid.
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.
Answer:
b
Step-by-step explanation:
Choice b is the only one that has the first equation properly graphed. The boundary line for that equation will have intercepts that can be found by setting the opposite variable to zero.
x-intercept = 25/2 = 12.5 (on the positive x-axis)
y-intercept = 25/5 = 5 (on the positive y-axis)
That is, the boundary line has a shallow negative slope, and is shaded below. Only graph 'b' has such a line.
