Step-by-step explanation:

ok, logic

all of them are parabolas

1st and 3rd are opening up, so they defenitely increase, so no

decraseing

the vertex hs to be be at x=-4

y=a(x-h)^2+k

h has to be -4

y=a(x+4)^2+k

the answer is 2nd one or f(x)=-(x+4)^2+4

22.5(10-y)+27.5y=250
Nataliya [291]

Answer:

y = 5

Step-by-step explanation:

22.5(10-y)+27.5y=250

225 - 22.5y + 27.5y = 250\\\\

Combind like terms,

225 + 5y = 250

Subtract 225 from both equations to isolate the variable.

5y = 25

Divide both sides by 5 to isolate the variable and solve it.

y = 5

3 1/3 - 1 2/3 = ? Help me plzz i beg you i lost my notes :(
tamaranim1 [39]
You turn them into improper fractions by multiplying the bottom number to the whole number then adding the product to the top of the fraction, therefore 
3 1/3 = 10/3, and 1 2/3 = 5/3

10 _ 5  =  5/3

Answer:

 h(x) =  -x² + 11 x + 2

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the functions are  

                                            f(x) = 2 x² - 5x -3

                                            g(x) = x² + 6x -1

               h(x)  = g(x) - f(x)

                      = x² + 6x -1 - (2 x² - 5x -3)

                     = - x² + 6 x +5x -1+3

                    = -x² + 11 x + 2

            h(x) =  -x² + 11 x + 2

<u><em>Final answer:-</em></u>

h(x) =  -x² + 11 x + 2
