Answer:

x = -7/2

Step-by-step explanation:

-(7-2x)+7=-7

-7 -7

Start by subtracting -7 from both sides.

-(7-2x) = -14

Divide both sides by -1 to eliminate the negatives.

-(7-2x) = -14

--------- -------

-1 -1

Simplify.

7-2x = 14

Subtract -7 from both sides.

-2x = -7

Divide both sides by -2

-2x = -7

----- ----

-2 -2

x= -7/2

Check if -7/2 by plugging it back into the equation: (-7/2 = -3.5)

-(7-2(-3.5))+7 = -7

Zolol [24]

Answer:

The graph is shown below.

The time to make the taste to half is 4.265 s.

Step-by-step explanation:

Given:

Initial value of the taste is, $Q_0=1$

Therefore, the quality of taste over time 't' is given as:

$Q(t)=Q_0(0.85)^t\\Q(t)=1(0.85)^t$

Now, when the taste reduces to half, $Q=0.5$

Therefore,

$0.5=1(0.85)^t$

Taking natural log on both the sides, we get:

$\ln(0.5)=\ln(0.85)^t\\\ln(0.5)=t\ln(0.85)\\t=\frac{ln(0.5)}{\ln(0.85)}=4.265\ s$

Therefore, the time to make the taste to half is 4.265 s.
