Answer:
y= -7 and x= -1
Step-by-step explanation:
To do this, line up the variables so it looks like this...
y-6x=-1
y-3x=-4
The reason why -6x and -3y changes to negative is because that it moved to the other side of the equation.
distribute negative to the bottom equation because the two equations have the same number variable which is y...
y-6x=-1
-y+3x=4
Y cancels out and it will be left with -3x = 3.
X = -1.... plug that in to any of the two equation and you get y = -7.
Hope I helped and have a nice day!!
Answer:
D = { -4,-1,3,5,6}
Step-by-step explanation:
The domain is the x values or the inputs
D = { 3,6,-1,5,-4}
We normally put them in order from smallest to largest
D = { -4,-1,3,5,6}
Answer:
14.9 km/hr
Step-by-step explanation:
We know

v = 82km / 5.5 hr
v = 14.90 km/hr
1.Find the Lowest Common Denominator(LCD) of the fractions.
Rename the fractions to have the LCD.
Subtract the numerators of the fractions.
The difference will be the numerator and the LCD will be the denominator of the answer.
Simplify the Fraction.
