Pls help answering a b and c
Anastasy [175]

Answer:

a) The very first one where the line starts to the left

b) m=125.82

c) 320.81 thousand dollars

Step-by-step explanation:

a) The point on the graph who corresponds to x=3 years and Salary=$200,000 is the very first one where the line starts to the left

b) If a line is given by Y=mx+b, m represents the slope of the line. In this case, m=125.82 which can be interpreted as the rate of growth of the salary per year in thousands of dollars. A doctor can expect to earn 125.82 thousand dollars more than the previous year.

c) If we use the given regression line Y=125.82x-182.47 and make x=4, we get

y=125.82 (4)-182.47 =320.81 thousand dollars

The graph of the function y=25 - x what is the domain of the function
lakkis [162]
The domain of a function is defined as the set of values of x that will give out a real value of y, a "real" number is basically a number that can be expressed as itself instead of as a symbol or a calculation, for example -4 would be a real number as we can simply express it as -4, however √-4 would not be a real number as it would be expressed as 2i. For the function y=25-x all values of x will result in a real number therefore we say domain of f(x) is x∈R, or simply saying "the domain of the function y=25-x is all real values of x" will probably suffice.

Y
kiruha [24]

Answer:

x = 400 when y = 100

Step-by-step explanation:

This is a question in relation to direct variation.

y ∝ \sqrt{x}

y = k \sqrt{x}

Given that, y = 45, x = 81. Then;

45 = k \sqrt{81}

45 = 9k

k = \frac{45}{9}

k = 5

Thus the relationship among the variables is;

y = 5 \sqrt{x}

If y = 100, then;

100 = 5 \sqrt{x}

\sqrt{x} = \frac{100}{5}

\sqrt{x} = 20

x = (20)^{2}

x = 400

Therefore, x = 400 when y = 100.
