Answer:
(-1, -2)
Step-by-step explanation:
Plug (x-1) for y in the first equation:
-4x + 3(x-1) = -2
Simplify:
-4x + 3x - 3 = -2
-x = 1
x = -1
Plug in x=-1 into the second equation:
y = (-1) - 1
y = -2
The area painted red on one of the front wheels on DeMarius’ car will be 80.42 inches².
<h3>How to calculate the area?</h3>
From the information given, the The front wheels on DeMarius’ car are divided into sectors of equal area and the radius of each wheel is 8 inches. The area will be:
= 2/5 × πr²
= 0.4 × 3.14 × 8²
= 80.42 inches²
The radius, in feet, of a rear wheel on the car will be:
r1(2π) = r2(2π)
8(2π) = r2(8/5)(2π)
16 = r2(8/5)
r = 5/8 × 16
r = 10 inches
r = (5/6) feet

Where will the mean approach if sample size increase
Using central limit theorem, we have:
This means that; as n approaches infinity, the mean is almost expected to the 
i.e. expected to remain unchanged.
Hence, the mean value will approach 51.
