Classify the system of equations

Lelechka [254]

Answer: Inconsistent.

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

$y=mx+b$

Where m is the slope and b is the y-intercept.

Solve for y from each equation:

Equation 1:

$-\frac{1}{2} x = -6 - y\\\\y-\frac{1}{2} x = -6\\\\y=\frac{1}{2} x-6$

Equation 2:

$3+y= \frac{1}{2} x + 4\\\\y= \frac{1}{2} x + 4-3\\\\y= \frac{1}{2} x+1$

A system of equations can be classified by its number of solutions.

You can observe that the slopes of both equations are the same but the y-intercepts are different, then these lines are parallel, which means that they do not intersect.

By definition, when to lines are parallel there is NO SOLUTION and the system is classified as "Inconsistent".

a store sign reads take 75% off the original price when you take an additional 15% off the sale price which is 60% off the regul

Lelu [443]

I you take 75% off the original price, 25% remains.

If you take 60% off the original price, 40% remains. Taking 15% off that means you take off an additional 0.15*40% = 6% of the original price, so end up with
40% -6% = 34%
of the original price. This is considerably more than 25% of the original price.

The store sign is not accurate, because the "additional 15%" is of the sale price, not the original price.
