Answer:

<u>Given</u>

f(x) = 3x + 2
g(x) = (x + 3) / (2x - 10)

#1

g · f(x) =
g(f(x)) =
(3x + 2 + 3)/ (2(3x + 2) - 10) =
(3x + 5) / (6x - 6)

#2

f · g(x) =
f(g(x)) =
3[(3x + 2) / (2x - 10)] + 2 =
(9x + 6) / (2x - 10) + 2 =
(9x + 6 + 4x - 20)/ (2x - 10) =
(13x - 14) / (2x - 10)

8x + 5y = 22<br> -8x + y = 14

finlep [7]

Answer:

Y = 6 X=-1

Step-by-step explanation:

Add the numbers 8x+-8x=0. 5y+y=6y. 22+14=36
So that means 6y=36. So Y would equal 6
Substitute the values it one of the original equations. 8x + 5(6) =22. 8x+30=22
Minus 22 from both sides.
That would give you 8x=-8
So x would equal - 1

<em><u>The</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>9x</u></em><em><u>²</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>3x</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>2</u></em><em><u>.</u></em>

Step-by-step explanation:

1) Collect like terms.

$(7x^{2} + {2x}^{2} ) + ( - 2x + 5x) + (8 - 10)$

2) Simplify.

${9x}^{2} + 3x - 2$

2/3 of a number -11. Please help

vfiekz [6]

Answer:

(2/3)x = -11

x = -33/2

Step-by-step explanation:

2/3 of a number is -11.

Let the unknown number be x.

2/3 of x is -11.

(2/3)x = -11

Multiply both sides by 3/2.

(3/2)(2/3)x = (3/2)(-11/1)

x = -33/2
