Answer:

x = 12.5

Step-by-step explanation:

The value of x is part of the value of an angle in a triangle where the other angles are known. This suggests that the relevant theorem is the "angle sum theorem," which tells you the sum of angles in a triangle is 180°.

This gives you the equation ...

60° +60° +(4x+10°) = 180° . . . . total of all angles is 180°

4x +130° = 180° . . . . . . . . . . collect terms

4x = 50° . . . . . . . . . . . . subtract 130° from both sides

x = 12.5° . . . . . . . . . divide both sides by 4

scoray [572]

S=Years Susanna has played the piano
p=Years Patrick has played the piano

The expression for this question would be s(2)+4=p

Hope this helps! :)

Answer:

f[g(4)] = 4

Step-by-step explanation:

Given table:

$\begin{array}{| c | c | c | c | c | c |}\cline{1-6} x & -6 & -4 & 1 & 3 & 4\\\cline{1-6} f(x) & 4 & -1 & -6 & 1 & 3 \\\cline{1-6} g(x) & 1 & 4 & 3 & -4 & -6 \\\cline{1-6}\end{array}$

f[g(4)] is a composite function.

When calculating composite functions, always work from inside the brackets out.

Begin with g(4): g(4) is the value of function g(x) when x = 4.

From inspection of the given table, g(4) = -6

Therefore, f[g(4)] = f(-6)

f(-6) is the value of function f(x) when x = -6.

From inspection of the given table, f(-6) = 4

Therefore, f[g(4)] = 4
