Answer:
b=7
Step-by-step explanation:
5a(2b – 3a) = 40
Let a=4
5*4(2b-3*4) = 40
20(2b-12) = 40
Divide each side by 20
20/20 (2b-12) = 40/20
2b-12 =2
Add 12 to each side
2b-12+12 = 2+12
2b = 14
Divide by 2
2b/2 = 14/2
b = 7
Answer:
f(x) = -logx + 4.
Step-by-step explanation:
y = -log x approaches the point (0, 1) but this approaches (0, 5)
Looks like the graph of - log x + 4.

Answer: <em>x = 7.5</em></h2>
<em />
Step-by-step explanation:
Use the Pythagorean Theorem (
)
The longest side is <em>c = the hypotenuse</em>, and <em>a and b = the other sides</em> of the triangle.
a = 4 First: 
b = x Second:
c = 8.5 Third: 
Fourth: 
Fifth: x = 7.5
