Answer:
Option x-12 is correct
Therefore the quotient for the given rational expression is x-12
Step-by-step explanation:
Given rational expression is
To find the quotient for the given rational expression :
<u>_x-12________</u>
x+5 ) x^2-7x+8
x^2+5x
__(-)__(-)_______
0x^2-12x+8
-12x-60
______(+)__(+)____
68
________________
Therefore the quotient is x-12
Option x-12 is correct
So you have
25x+10y=24
and
x+y=20
you can eith er subsitue or add
let's add
mutliply x+y=10 by -10
-10x-10y=-200
add to first equation
25x+10y=24
<u>-10x-10y=-200 +
</u>15x+0y=-176
15x=-176
divide both sides by 15
x=-176/15
subsitue
x+y=20
-176/15+y=20
add -176/15 to both sides
y=476/15
solution
(x,y)
