Answer:

x = 9

Step-by-step explanation:

angle 1 plus angle 2 equals 90 because they are complementary. combining like terms gives you 8x + 18 = 90. then you get 8x = 72, which means that x equals 9

On the graph of the equation X-4Y= -16 what is the value of the Y-intercept?

Nonamiya [84]

we can always find the x-intercept by simply settting y = 0, and solving for "x".

and we can always find the y-intercept by simply setting x = 0 and solving for "y".

$\bf x-4y=-16\implies \stackrel{x=0}{0-4y=-16}\implies y=\cfrac{-16}{-4}\implies y=4

I need someone to explain how to solve this please!

Paladinen [302]

(x+3)/2x+5 + (3x-5)/(3x+5)

LCM = ( 2x+5)( 3x+5)

[( x+3)( 3x+5) + ( 3x -5)( 2x+5)]/( 2x+5)( 3x+5)

= (3x^2 + 5x +9 x +15 + 6x^2 + 15x -10x -25)/( 2x+5)( 3x+5)

=( 9 x^2 + 19x -10)/( 2x +5)(3x+5)
