Answer:

13. -2

14. 0

15. 2

16. 0

Step-by-step explanation:

Since the function is originally f(x), you go to wherever the x value is and see what the y value is.

So...

f(2) means go to x = 2 and see that y = -2

Answer:

[tex]\frac{73}{9}[/tex]

Step-by-step explanation:

To change to an improper fraction

Multiply the whole number part and the denominator of the fraction

Then add the numerator

The denominator remains as 9 , that is

8 [tex]\frac{1}{9}[/tex] = [tex]\frac{8(9)+1}{9}[/tex] = [tex]\frac{72+1}{9}[/tex] = [tex]\frac{73}{9}[/tex]

Answer:

[tex] {x}^{2} + 5x = - 2[/tex]

arrange the equation according to general formula;

General formula: ax² + bx + c = 0

therefore:

[tex] {x}^{2} + 5x + 2 = 0[/tex]

Using the quadratic equation :

[tex]x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a} \\ [/tex]

a » 1, b » 5, c » 2

substitute:

[tex]x = \frac{ - 5± \sqrt{ {5}^{2} - (4 \times 1 \times 2) } }{(2 \times 1)} \\ \\ x = \frac{ - 5± \sqrt{17} }{2} [/tex]

therefore solutions are;

[tex]{ \boxed{ \boxed{x_{1} = \frac{ - 5 + \sqrt{17} }{2} }}} \: \: and \: \: { \boxed{ \boxed{x_{2} = \frac{ - 5 - \sqrt{17} }{2} }}}[/tex]

x is -0.438 and -4.562

Answer:

The domain of g(x) is the set of all real numbers. Also, g(g(x)) is defined for the set of all real numbers. Therefore, the domain of is the set of gg D all real numbers

Step-by-step explanation:

Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited

The opposite angles formed on an intersecting line are equal.

Here,

angle y + 10 = angle 2y - 80

Now,

y + 10 = 2y - 80

10 + 80 = 2y - y

90 = y

Therefore,

The angle y + 10 measures 100°.

Also, angle 2y - 80 measures 100°.

The other two angles measure 80° each.
