Answer:

D) -30x^2 -64x -18

Step-by-step explanation:

Given:

f(x) = 6x +2 and g(x) = -5x - 9

f(x).g(x) = (6x + 2) (-5x - 9)

Use distributive property

= 6x(-5x -9) + 2(-5x - 9)

= -30x^2 - 54x - 10x -18

= -30x^2 -64x - 18

Answer: d) -30x^2 -64x -18

Thank you.

What is the solution to the system of equations y23x3 x 2
bija089 [108]

The Solution for the given system of equations is (-2) and (\frac{5}{3}).

The given are linear equations as follow:
y = \frac{2}{3}x + 3              .. ... ...(1)
and x  = -2.          .. .... ...(2)

We already know the first part of the solution (x) which is -2.  We can find the other part (y) by putting the value of equation (2) in equation (1).

By putting the values of x in equation (1), we get

y = (\frac{2}{3})(-2) + 3
y = \frac{-4}{3} + 3

Taking the L. C. M of denominators which will be '3', we get:

y = \frac{-4 + 9}{3}

y = \frac{5}{3}

So the second part (y) of the solution of the given equation is \frac{5}{3}.

Hence, the overall solution to the given system of equation is (-2, \frac{5}{3}).

What is the area of this figure?<br><br> Enter your answer in the box.
earnstyle [38]
To find the area you do base times height. Base is the number across,and height is the number that is up and down.So in this case you will multiply 9 and 5 and 9 and 7 and get 45 and 72.Then you will add 45 and 72 together and get 117. So the area is 117. Answer 117. Hope this helps :D.

Help meeee!!!!!!!!!!!!!!!!!!!
Ivenika [448]

Answer:

Y=-2x

When x= -6 then y =12

Step-by-step explanation:

If y and x in direct variation then y=c*x for some constant c.

We are told

-4=c2

——> c= -2

So y= -2x

When x= -6 this becomes

Y= (-2) * (-6)

——> y = 12
