Answer:1)5x^2-11x

2) x^2-3x

Step-by-step explanation:

1)(f+g)(x)

f(x)=3x-7

g(x)= 2x-4

[(3x-7)+(2x-4)](x)

3x^2-7x+2x6^2-4x

=<u>5x^2-11x</u>

2) (f-g)(x)

[(3x-7)-(2x-4)](x)

(3x-7-2x+4)(x)

3x^2-7x-2x^2+4x

x^2-3x

Angl is a square. The equation of line NG is Y= 1/2 X - 6. Find the equation of line LG in slope intercept form given that the c

Irina18 [472]

Answer: y=-2x-9

Step-by-step explanation:

If ANGL is a square, then NG and LG are adjacent sides.

Adjacent sides are perpendicular. [Each angle is 90°]

The equation of line NG is $Y=\dfrac12 X-6$ .

By comparing it to equation in slope intercept form y=mx+c ( where , m= slope , c=y-interecpt)

slope = $\dfrac12$

Let slope of LG be <em>n</em>, then

$n\times \dfrac{1}{2}=-1$ [Product of slopes of two perpendicular line =-1]

$\Rightarrow n=-2$

Equation of a line passes through (a,b) and have slope m is given by :-

$(y-b)=m(x-a)$

Equation of LG :

$(y-1)=-2(x-(-5))\\\\\Rightarrow\ y-1=-2x-10\\\\\Rightarrow\ y=-2x-9$ [In intercept form]
