-1/6 it seriously said “incorrect answer” when I tried to post it :|
Answer: The answer to a system of equations is the point(s) of intersection of the equation involved.
When you have more than one equation with more than one variable, you have a system of equation. The solution(s) is the set of values for each variable that satisfy the equations. This means that the inputting values make the equations true.
f(x) = -x + 2
f(-1) This means that they want you to find the value of f(x) or y when x = -1.
f(x) = -x + 2 Substitute/plug in -1 into "x" since x = -1
f(-1) = -(-1) + 2 (two negative signs cancel each other out and become positive)
f(-1) = 1 + 2
f(-1) = 3
11.25×12.5 = 140.625.
Depending on your class, you may only need 140 or round to 141.
Using relations in a right triangle, it is found that:
tan(A) = 3/4 = 0.75.
<h3>What are the relations in a right triangle?</h3>
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
In this triangle:
- The adjacent side to A has length 40.
- The opposite side to A has length 30.
Hence the tangent of A is:
tan(A) = 30/40 = 3/4 = 0.75.
