$F(x)=6x+3\\\\ y=6x+3\\ 6x=y-3\\ x=\dfrac{y-3}{6}\\\\ F^{-1}(x)=\dfrac{x-3}{6}\Rightarrow \text{B}$

Which of the following describes the situation below? The number of miles a car can run depends on the gallons of gasoline in th

S_A_V [24]

Answer: A. A relation that is a function.

Step-by-step explanation:

A relation is said to be a function if each input value is associated with one unique output value.

Here, Number of miles run by car is directly proportional to the quantity of gasoline.

Independent variable - quantity of gasoline.

Dependent variable - Number of miles

On assuming the condition of car as good, the number of miles a car can run highly depends on the gallons of gasoline in the tank .

As quantity of gasoline increases number of miles driven would also increases.

i.e. Number of miles driven is a function with respect to quantity of gasoline.

Hence, the given line best describe as : A relation that is afunction.

Please help! I get how to do the first part I just don't get how to do the second part.

Answer:

WX = 33

(x, y) = (2, 10)

Step-by-step explanation:

The hash marks tell you WX is a midline, so has the measure of the average of the two bases.

WX = (PQ +SR)/2 = (27 +39)/2 = 66/2

WX = 33

The hash marks also tell you ...

PW = WS

y +4x = 18 . . . . . . substitute the given expressions

and also

QX = XR

2y +x = 22 . . . . . substitute the given expressions

If you solve the first equation for y, you get ...

y = 18 -4x

Substituting that into the second equation gives ...

2(18-4x) +x = 22

36 -7x = 22 . . . . . . . simplify

14 = 7x . . . . . . . . . . . add 7x-22 to both sides

2 = x . . . . . . . . . . . . divide by 7

y = 18 -4(2) = 10 . . . find y using the above relation

The values of x and y are 2 and 10, respectively.

My favorite "quick and dirty" way to solve a set of linear equations is using a graphing calculator. It works well for integer solutions.
