PKEASE HELP Based on the graph, what is one solution of the equation f(x) = g(x)? graph of function f of x equals negative x plu
Oksanka [162]

Answer:

x=1

x=-5

Step-by-step explanation:

we know that

The solution of the system of equations is the intersection point both graphs

In this problem there are two intersection points

so

The system has two solutions

we have

one solution is the point (-4.9, 5.4) and the other (0.92, -0.42)

see the attached figure

therefore

x=1

x=-5

An airplane leaves an airport and flies due west 150 miles and then 170 miles in the direction S 49.17°W. How far is the plane f
Basile [38]
Notice the picture below

what we have, is really an angle, encroached by two sides

thus, use the Law of Cosines

\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies 
c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}\\\\
-----------------------------\\\\
\textit{so the distance "c" from the airplane to the airport}\\
\textit{using angle C, and the sides "a" and "b"}
\\\\\\
c=\sqrt{150^2+170^2-(2\cdot 150\cdot 170)cos(49.17^o)}\qquad
\begin{cases}
a=150\\
b=170\\
C=49.17^o
\end{cases}

3+5+7=15
15÷3=5

Levart [38]

The equation will have only one solution. The value of x is -5.

<h3>What is an equation?</h3>

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given equation x + 10 = 5  will be solved as below:-

x + 10 = 5

Take 10 to the right of the equation.

x = 5 - 10

x = -5

The equation is giving the value of x equal to -5. Then the equation will have only one solution.

Therefore, the equation will have only one solution. The value of x is -5.
