Evaluate f(x) when x = -10

Mathematics

Answer: -24

Step-by-step explanation:

Step one :

For the first equation

Given that x=-10

F(x) =2x-4 if 3<x<10

x exists in this domain

Substituting x in the equation we have

F(-10)=2(-10)-4

F(-10)= -20-4

F(-10)=-24

Step two :

For the second equation

Given that x=-10

F(x) =x²-+3 if 10<=x<13

x does not exist in this domain

So, when x = -10.


If you notice, -10 is NOT in the domain (the domain is (-3,13))

so, there is no solution.

Which point represents a solution to the system y ≤ (1)/(5)x y &gt; 4x-3 select all that apply
jeyben [28]
The system is 

i) y \leq  \frac{1}{5} x
ii) y\ \textgreater \ 4x-3

The solutions to this system, are all points (x, y) for which BOTH these 2 inequalities hold.

Check the points separately: 

(5, 1)
i) 1 \leq \frac{1}{5} *5=1 True
ii) 1\ \textgreater \ 4*5-3=20-3=17 Not True

(0, 0)
i) 0 \leq \frac{1}{5} *0=0 True
ii) 0\ \textgreater \ 4*0-3=-3 True

(-2, -3)
i) -3 \leq \frac{1}{5} (-2)= \frac{-2}{5}= -0.4 True
ii) -3\ \textgreater \ 4(-2)-3=-8-3=-11 True

(2, 5)
i) 5 \leq \frac{1}{5}*2= \frac{2}{5} =0.4 Not True
ii)5\ \textgreater \ 4*2-3=8-3=5 Not True


Answer: (0, 0) and (-2, -3)
