Answer:
x=-6
Step-by-step explanation:
y=2x + 5
y= x -1
Plug in the equation for y
x-1=2x+5
Combine like terms
-1=x+5
-6=x

Answer:
33.1698
Step-by-step explanation:
10
∫ 13y/ y^2-9y-22 .dy
-1
Let's break down the fraction first before we integrate
13y/ y^2-9y-22
= 13y/(y-11)(y+2)
=11/(y-11) + 2/(y+2)
Time to Integrate.
10
∫ 13y/ y^2-9y-22 .dy
-1
=∫ 11/(y-11) dy+ ∫ 2/(y+2) Dy
= 11In(y-11) + 2 In(y+2)
When y = 10
= 11In(10-11) + 2In(10+2)
= 11In1 + 2In12
= 4.9698
When y = -2
= 11In(y-11) + 2 In(y+2)
= 11In(-2-11) + 2In(-2+2)
= -28.2
4.9698+28.2= 33.1698
