Answer: g(x) which is the middle graph

=======================================

Explanation:

Average rate of change is the same as slope through the two endpoints of the interval

For f(x), (1,-2) and (3,6) are on the graph

Slope
m = (y2-y1)/(x2-x1)
m = (6-(-2))/(3-1)
m = (6+2)/(3-1)
m = 8/2
m = 4
So we can rule out f(x) because we want the slope to be 3, not 4.

-------------------------
Let's try g(x)

Based on the given curve, we can see that (1,-2) and (3,4) are on the g(x) graph.

Slope
m = (y2-y1)/(x2-x1)
m = (4-(-2))/(3-1)
m = (4+2)/(3-1)
m = 6/2
m = 3
We found the answer, but let's check h(x) just for the sake of completeness
-------------------------

If we plug x = 1 and x = 3 into h(x), we get y = 1/2 and y = 19/8 respectively
So the two points (1,1/2) and (3,19/8) are on the graph

Slope
m = (y2-y1)/(x2-x1)
m = (19/8-1/2)/(3-1)
m = (19/8-4/8)/(3-1)
m = (15/8)/(2)
m = (15/8)*(1/2)
m = 15/16
which is not equal to 3, so we can rule out h(x)

Makayla has $8 to buy tickets at the school fair. each ticket costs $1.50. which inequality best represents how many tickets she
forsale [732]

Answer:

N < 5

Step-by-step explanation:

"Makayla has $8 to buy tickets at the school fair. each ticket costs $1.50" can be written as $8 = ($1.50/ticket)*N.

Dividing both sides by ($1.50/ticket) results in

        $8

---------------------- = 5 1/3 tickets

 ($1.50/ticket)

or N < 5.

Your answer should be a polynomial in standard form. ( − 2 h + 9 ) ( 9 h − 2 ) = (−2h+9)(9h−2)=
AleksandrR [38]

Answer:

-18\cdot h^{2} + 85\cdot h - 18

Step-by-step explanation:

The polynomial in standard form is:

(-2\cdot h + 9) \cdot (9\cdot h - 2)

-18\cdot h^{2} + 81\cdot h +4 \cdot h - 18

-18\cdot h^{2} + 85\cdot h - 18

Simplify fully: X^2+3x-4/ 2x^2-5x+3
sweet-ann [11.9K]

Answer:

(-x - 3) • (x - 1)

Step-by-step explanation:

Step  1  :

           2

Simplify   —

           1

Equation at the end of step  1  :

 ((((x2)+3x)-(2•x2))-5x)+3

Step  2  :

Equation at the end of step  2  :

 ((((x2) +  3x) -  2x2) -  5x) +  3

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  -x2 - 2x + 3  =   -1 • (x2 + 2x - 3)

Trying to factor by splitting the middle term

4.2     Factoring  x2 + 2x - 3

The first term is,  x2  its coefficient is  1 .

The middle term is,  +2x  its coefficient is  2 .

The last term, "the constant", is  -3

Step-1 : Multiply the coefficient of the first term by the constant   1 • -3 = -3

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   2 .

     -3    +    1    =    -2

     -1    +    3    =    2    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -1  and  3

                    x2 - 1x + 3x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-1)

             Add up the last 2 terms, pulling out common factors :

                   3 • (x-1)

Step-5 : Add up the four terms of step 4 :

                   (x+3)  •  (x-1)

            Which is the desired factorization

Final result :

 (-x - 3) • (x - 1)
