F (x)= 5x-14 G (x)= 12x+8 H (x)= 62x-54 Dadas las funciones resolver las siguientes operaciones a. F (x)+ G (x) b. G (x)- (H (x)

Alborosie

Answer:

a) $17\cdot x -6$ , b) $-45\cdot x +48$ , c) $518\cdot x^{2} +1306\cdot x -1012$ , d) $\frac{-57\cdot x +40}{17\cdot x -6}$ , e) $2\cdot \left(\frac{3\cdot x + 2}{31\cdot x - 27} \right)$

Step-by-step explanation:

Sean $f(x) = 5\cdot x -14$ , $g(x) = 12\cdot x + 8$ y $h(x) = 62\cdot x - 54$ . A continuación, desarrollamos las siguientes operaciones:

a) $f(x) + g(x)$

$(5\cdot x - 14) + (12\cdot x + 8)$

$17\cdot x -6$

b) $g(x) - [h(x)-f(x)]$

$(12\cdot x + 8) - [(62\cdot x - 54)-(5\cdot x - 14)]$

$12\cdot x + 8 - (57\cdot x -40)$

$12\cdot x +8 -57\cdot x +40$

$-45\cdot x +48$

c) $[g(x)-f(x)]\cdot [h(x)+g(x)]$

$[(12\cdot x + 8)-(5\cdot x -14)]\cdot [(62\cdot x -54)+(12\cdot x +8)]$

$(12\cdot x +8 -5\cdot x +14) \cdot (62\cdot x -54+12\cdot x+8)$

$(7\cdot x +22)\cdot (74\cdot x-46)$

$7\cdot x \cdot (74\cdot x - 46)+22\cdot (74\cdot x -46)$

$(7\cdot x)\cdot (74\cdot x) - 46\cdot (7\cdot x )+22\cdot (74\cdot x)-22\cdot (46)$

$518\cdot x^{2}-322\cdot x +1628\cdot x -1012$

$518\cdot x^{2} +1306\cdot x -1012$

d) $\frac{f(x)-h(x)}{g(x) + f(x) }$

$\frac{(5\cdot x - 14)-(62\cdot x - 54)}{(12\cdot x +8)+(5\cdot x -14)}$

$\frac{-57\cdot x +40}{17\cdot x -6}$

e) $\frac{g(x)}{h(x)}$

$\frac{12\cdot x + 8}{62\cdot x - 54}$

$\frac{4\cdot (3\cdot x +2)}{2\cdot (31\cdot x -27)}$

$2\cdot \left(\frac{3\cdot x + 2}{31\cdot x - 27} \right)$

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The correct option is A, BC < MN.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

As per the given conditions, the angle that will be opposite to ∠A is BC and ∠L is MN.

Now since the measure of ∠L is more than the measure of ∠A, therefore, the side MN will be greater than BC.

Hence, the correct option is A, BC < MN.

Which steps can be used to solve for the value of y ? 23(y+57)=178

Allushta [10]

Answer:

y= -49.26 or -49 6/23

Step-by-step explanation:

First distribute the 23 to y and 57

23y+1311=178

then subtract 1311 from both sides

23y=-1133

Then divide 23 to both sides

y= -49.2608695652

rounded: -49.3

as a fraction: -49 6/23
