Ok, first you need to read a - g and mark down the information you know. Also, this continuous function can look pretty much like anything long as it has the a - g constraints/rule. 

A) We know the domain(x values) is between -10 to infinity
(-10,-9,-8,-7,-6,-5,-4,-3-,2,-1,0,1,2,3,4,5,6,7,8,9,10, to ---------> infinity)
B) We know the range(y values) is between -6 to infinity
(-6,-5,-4,-3-,2,-1,01,2,3,4,5,6,7,8,9,10, to ---------> infinity) 

C) Next we know f(0) = f(4) = 0
So we know when x = 0  that f(0) = 0 or we can say  y = 0. We also know when f(4) = 0 so when x = 4 y = 0. So we have two points (0,0) and (4,0) that our function will be on so plot the two points (0,0) (4,0)

D) It tells us that f(x) (y) is increasing between the x values (-10,-6)  or (-2,2) or (4, to infinity)

E) It tells us that f(x) (y) is decreasing between the x values (-6,-2) or between (2,4)

F) Tells us that f(x) (y) is greater than or equal to between the x values of [-8,-4] or between the x values [0, to infinity) so this lets us know our drawing is going to be above or equal to 0 when we are in the values [-8,-4] or [0, to infinity)

G) Tells us that f(x) (y) is less than 0 when the function / drawing is between the x values of (-10, -8) or (-4,0)  

The picture is what the function could look like. It can be different but needs to following the rules that are given

7/16 divided by 2 3/8
Alexandra [31]
=>  \frac{7}{16}    ÷    2\frac{3}{8}
                                                    convert to improper fraction
=>  \frac{7}{16}    ÷    \frac{19}{8}
                                                     convert to multiply
=>  \frac{7}{16}    ×   \frac{19}{8}
                                                     simplify and solve

=>   \frac{7}{2}     ×   \frac{1}{19}

=>   \frac{7}{38}

Solve this equation <br> 3x-1/5-2/9x=124/5
Flauer [41]

Answer: x = 9

Step-by-step explanation:

1) Combine multiplied terms into a single fraction

2) Find a common denominator

3) Combine fractions with common denominator

4) Multiply from left to right (PEMDAS)

5) Multiply all terms by the same value to eliminate fraction denominators

6) Cancel multiplied terms that are in the denominator

7) Multiply again

8) Add _ to both sides

9)  Divide both sides by the same factor getting 125x/125 = 1125/125

10) Simplify, x = 9
