How do you solve this problem 3/2=x/324 i'm stuck

1 answer:

You have to find a common denominator. In this case it will be 486/324 = x/324. Then you would have to turn the 324 around. Then it will be 486/324 X 324. Which would be 486. Therefore. X = 486. Please tell me if I am wrong. Your welcome!

93. $g(n) = n - 4$
$f(n) = 2n^2 - 5n$

then $g(n) +f(n) = (n-4) + (2n^2 - 5n)$
                                $= n - 4 + 2n^2 - 5n$
                                $= 2n^2 -5n + n - 4$
                                $= 2n^2 - 4n -4$

95. $f(n) = -n+3$
      $g(n) = n^3 + 3n$
Then $f(n) . g(n) = (-n+3) . (n^3 + 3n)$
                                 $= -n^4 + 3n^3 - 3n^2 + 9n$

97. $f(x) = 3x+1$
$g(x) = 2x$
For finding f(g(x)) we will plugin value of g(x) in place of x in f(x).
$f(g(x)) = 3*(2x) + 1$
                  $= 6x + 1$

99. $f(n) = n - 3$
$g(n) = 2n^2 - 3n$

$g(-7) = 2*(-7)^2 - 3 * (-7) = 2* 49 + 21 = 98 + 21 = 119$
$f(g(-7)) = 119 - 3 = 116$

What do I type in the box pls help???

Answer:

f(x)=3x-5

g(x)=-6x²+6x+2

f(x)×g(x)

=(3x-5)(-6x²+6x+2)( use distributive property)

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

=(-18x³)+(18x²)+6x+30x²-30x-10

=-18x³+18x²+6x-30x+30x²-10

=-18x³+18x²-24x+30x²-10

=-18x³+18x²+30x²-10

=-18x³+48x²-10---------------you may write this answer

Hope it's was clear,

Which equation shows how (–10, 8) can be used to write the equation of this line in point-slope form?

liq [111]

It would be be the first solution, as it follows the format of (y y1) = m(x-x1)

Find the solution of this system of equations<br> -2y = 48 + 6x<br> -6x + 9y = -84

anygoal [31]

-2y = 48 + 6x
-6x - 2y = 48 ——(1)

-6x + 9y = -84
-6x = -84 -9y ——(2)

Substitute (2) into (1):
(-84 -9y) -2y = 48
-84 -9y -2y = 48
-84 -11y = 48
-11y = 48 + 84
-11y = 132
y = - 12

Substitute y = -12 into (1):
-6x -2(-12) = 48
-6x + 24 = 48
-6x = 48 -24
-6x = 24
X = -4

ANS : y= -12, x= -4
