<u>Answer:</u>
x =
& 3
<u>Step-by-step explanation:</u>
= 
Cross multiply:
=
⇒ (8x)(7x) = (5x+3)(10x-2)
Simplify both sides:
(8x)(7x) = (5x+3)(10x-2) ⇒ 56x² = 50x²+20x-6
Set equation equal to 0:
56x² = 50x²+20x-6 ⇒ 0 = -6x²+20x-6
Factor the trinomial:
0 = -6x²+20x-6 = (-6x+2)(x-3)
Solve for X:
-6x+2 = 0
-6x = -2
x =
;
x-3 = 0
x = 3;
x =
, 3
Answer:
14m
Step-by-step explanation:
<em>Greetings from Brasil...</em>
We have here a composite function.... Where there is X in function F(X), we will replace by G(X)
F(X) = 2X + 4
G(X) = X - 7
H(X) = 9 - X
F(X) = 2X + 4
F(G(X)) = 2·(GX) + 4
F(G(X)) = 2·(X - 7) + 4
F(G(X)) = 2X - 14 + 4
<h2>F(G(X)) = 2X - 10</h2>
