Determine the solution to f(x) = g(x) using the following system of equations: (5 points) f(x) = 3x − 23 g(x) = −4.5x + 7
1 answer:
Answer:
(The solution is (4, -11).
Step-by-stp explanation:
Let f(x) = g(x) = y:
y = 3x − 23
y = -4.5x + 7 Subtract the second equation from the first to eliminate y:
0 = 7.5x - 30
7.5x = 30
x = 4
Plug this into the first equation:
y = 3(4) - 23
y = -11.

Answer:
13.9 inches, 14.1 inches
Step-by-step explanation:
The empirical rule tells you 68% of the distribution lies within 1 standard deviation of the mean:
14.0 ± 0.1 = [13.9, 14.1]
About 68% of outside diameters lie between 13.9 inches and 14.1 inches.
