(-2/3, 2)
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
Domain : D{-∞,∞} the reals.
Step-by-step explanation:
The function is plotted in the image.
[tex] f(x) = -3.15 * x + 723.45 [tex]
the linear functions usually have a domain from - infinite to infinite, the domain when is a piece wise function or discontinuous, the domain is defined in the pieces where is defined.
In this case there is no restriction so the function is continuous.
Answer:
D. 13.267 m
Step-by-step explanation:
We can use the Pythagorean theorem to solve this problem
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
7^2 + b^2 = 15^2
49 + b^2 = 225
Subtract 49 from each side
b^2 = 225-49
b^2 =176
Take the square root of each side
sqrt(b^2) = sqrt(176)
b = sqrt(176)
b = 13.266
