Answer: x = -2 and x = -1
Explanation:
The solution of an equality is the set of values of the unknown for which both members are equal. In this case, the values of x for which the two functions are equal.
The table shows three values of x for which the outputs of both f(x) and g(x) are equal. Those values of x are the solutions of the equality f(x) = g(x).
Such points are:
(-2,4) and (-1,2).
Realize that means that for x = -2 and x = -1, the values of both functions f(x) and g(x) are the same.
So, according to the table, x = -2, and x = -1 are solutions to f(x) = g(x)
Answer: All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Step-by-step explanation:
<u>Part A</u>
According to the Empirical Rule, 99.7% of the data in a normal distribution are ±3σ standard deviations away from the mean. Hence, approximately 99.7% of women over seventy have blood pressures between 134-3σ = 134-3(7) = 134-21 = 113 mmHg and 134+3σ = 134+3(7) = 134+21 = 155 mmHg.
<u>Part B</u>
As 141-134=134-127=7, this represents ±1σ standard deviations away from the mean of 134 mmHg, which corresponds to 68% of the data by the Empirical Rule. Hence, approximately 68% of women over seventy have blood pressures between 127 mmHg and 141 mmHg
