What is the solution to the system of equation
3x-6y=-12
x-2y=-8
(a) use substitution method to justify the given system of equation has no solution?
(b) what do you know about the two in the system of equation?

No solution

The lines are parallel

Step-by-step explanation:

To solve, use one equation and isolate x. Then substitute x into an equation.

x = -8 + 2y will be substitute 3x - 6y = -12.

3(-8 + 2y) -6y = -12

-24 + 6y - 6y = -12

-24 = -12

This is a false statement. The variable was eliminated. There is no solution. This means the lines are parallel.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.
