Answer:
Step-by-step explanation:
On this one you would eliminate the ones that are negative or that go into a negative. Which would be A,C, and E. The rest that are left are zero or positive. B for example is a zero because eventually there will be no candle. D would be the same in some way, the students will eventually leave the school. Finally F, the temperature would be increasing.
Answer - B,D,F
X=10 and x=0
Steps:
5x=x^2/2
10x=x^2
x^2-(10x)=0
(x-10)(x+0)=0
Solve for factors
x-10=0
x=10
x+0=0
x=0
Answer:
y = 12
Step-by-step explanation:
x - 1/2 y = -6
To find the y intercept set x = 0 and solve for y
0 - 1/2 y = -6
-1/2 y = -6
Multiply each side by -2
-2*-1/2y = -6*-2
y = 12
The answer is actually d lol the idiot above me was right
Answer:
If you subtract -2x+y=0 and -7x+3y=2 you will get 5x-2y=-2
Step-by-step explanation:
Subtract -2x and -7x which is 5x
Subtract y and 3y which is -2y
Subtract 0 and 2 which is -2
Result: 5x-2y=-2
Hope this helps!
