Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).

Answer:
x-intercept is x = -4; y-intercept is y = -2
Step-by-step explanation:
1.
The zero or x-intercept is when the line touches the x-axis or horizontal line axis or is when y = 0.
x = -4
2.
The y-intercept is when the line touches the y-axis or vertical line axis or is when x = 0.
y = -2
Answer:
Step-by-step explanation:
GIvn that Ming needs 1/2 pint of red paint for an art project
The 6 jars he has, have the following red paint in them
A. 2/3 pint
B.1/4 pint
C.4/6 pint
D.3/4 pint
E. 3/8 pint
F.2/6 pint
Since he want 1/2 pint he can use only jar B two times
First pour jar B contents equal to 1/4 pint to a new empty jar.
Now he can pour from A 1/4 pint to B, and then again use that
So altogether he gets 1/2 pint of red paint.
