Answer:

y = 3

Step-by-step explanation:

substitute the x in 2x - y = 7 by x = 3y - 4 and then solve

2(3y - 4) - y = 7

<em>Distribute the 2 into the parenthesis</em>

6y - 8 -y = 7

<em>combine like terms</em>

5y - 8 = 7

<em>add 8 on both sides</em>

5y = 15

<em>divide by 5 on both sides to isolate the y-value</em>

y = 3

Find the average value of the function f(x)=−4sin(x) on the interval [π2,3π2] and determine a number c in this interval for whic
Ber [7]

Answer:

Step-by-step explanation:

The average value theorem sets:

if f (x) is continuous in [a, b] and derivable in (a, b) there is a c Є (a, b) such that

\frac{f(b)-f(a)}{b-a}=f'(c) , where

f(a)=f(π/2)=-4*sin(π/2) = -4*1= -4

f(b)=(3π/2)=-4*sin(3π/2) = -4*-1 = 4

\frac{4-(-4)}{(3\pi/2)-(\pi/2)}=f'(c)

\frac{8}{\pi }=f'(c)

f'(x)=-4cos(x) ⇒

f'(c)=-4cos(c)=\frac{8}{\pi }\\c=acos(\frac{-2}{\pi })\\

c≅130
