Answer:

B

Step-by-step explanation:

To find the x- intercepts let f(x) = 0 , that is

(x + 1)(x + 4) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x + 1 = 0 ⇒ x = - 1

The x- intercepts are (- 4, 0 ) and (- 1, 0 )

B because x =-1 and -4 make f(x)=0

I will mark plus 25 pts. Help please A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh
olga nikolaevna [1]

    50(115-y) + 25y = 4125             [from eq2]

     5750 - 50y  + 25y = 4125           [distribute]

     5750 - 25y = 4125

      -25y = -1625

         y = 65             [divide both sides by (-25)]

 There are 65 small boxes.

Put that value into either equation (now, which is easier?) to solve for x:

  x = 115 - y

  x = 115 - 65

  x = 50

  There are 50 large boxes.

On friday ,a museum had 185 visitors.on saturday,there were twice as many visitors as Friday.On Sunday, 50 fewer people visited
Taya2010 [7]
This is the equation
185+185(2)+185-50
185+370+185-50 (you multiply 185 times 2 first)
370+370-50 (you add 185 to 185)
740-50 (you add 370 to 370)
740-50=690
There were 690 visitors during these three days.
