HERE ARE TWO NUMBER MACHINES A AND B
nika2105 [10]

Answer:

x=-7

Step-by-step explanation:

We can write them both like functions like this

A=5x-4

B=3x+8

Where

x=input

A=Output A

B=Output B

We want the output of A 3 times the output of B this can be written like this:

A=3B

we replace with the functions

5x-4=3(3x+8)

we solve for x

5x-4=9x+24\\5x-9x=24+4\\-4x=28\\x=\frac{28}{-4}\\x=-7

The output that makes the out put of A 3 times teh output of B is -7

Find the derivative of f(x) = 7x + 9 at x = 6
slava [35]
F(x)=7x+9
f´(x)=7
f´(6)=7

answer: f´(6)=7

f´(x)=Lim x⇒0   (f(x+h)-f(x)) / h
f´(6)=lim x⇒ 0   (7(6+h)+9 -(7*6+9)) / h
=lim x⇒0 ( 42+7h+9-42-9) /h
=lim x⇒0 (7h/h)=7

answer: f´(6)=7
