Answer:

False, also the typed version of this problem does not actually use the expression in the accompanying screenshot. That clearly reads as x + 5

Step-by-step explanation:

The problem, assuming x = 4 can be read as 4 + 5. Simple math dictates this would equal nine and as there is no negative to either number nor a negative outside of the lines surrounding the problem itself the solution is simple and leads to a false answer.

The answer is going to be false because if you subtract 51 from both sides, x will equal -60

Mixed numbers greater than 6 but less than 7 use an interval of 1/6 between each pair of numbers

GaryK [48]

Answer:

$[6\frac{1}{6},6\frac{1}{3},6\frac{1}{2},6\frac{2}{3},6\frac{5}{6}]$

Step-by-step explanation:

we have the compound inequality

$6 < x < 7$

where

x is a mixed number

so

The solution for the compound inequality are the numbers

$[6\frac{1}{6},6\frac{2}{6},6\frac{3}{6},6\frac{4}{6},6\frac{5}{6}]$

Simplify the numbers

$[6\frac{1}{6},6\frac{1}{3},6\frac{1}{2},6\frac{2}{3},6\frac{5}{6}]$

The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes)

saw5 [17]

Answer: $19.6

Step-by-step explanation:

Linear function: f(x)=mx+c

, where m= rate of change in f(x) with respect to x.

c = Initial value.

Let c = Initial value of card , m= Charge per minute

x= Number of minutes calling time.

Then, 25.06= 38m+c (i)

21.03=69m+c (ii)

Eliminate (ii) from (i)

$4.03=-31m\\\\\Rightarrow\ m=\dfrac{4.03}{-31}\\\\\Rightarrow\ m=-0.13$

Put m in (i) , we get

$25.06= 38(-0.13)+c\\\\\Rightarrow\ 25.06=-4.94+c\\\\\Rightarrow\ c=25.06+4.94\\\\\Rightarrow\ c=30$

i.e. f(x)=-0.13x+30

if x=80 then

f(80)= -0.13(80)+30

=-10.4+30

=19.6

Hence, the remaining credit after 80 minutes of calls = $19.6
