Which of the following is true about the function y=4*3^x
Trava [24]

Answer:

option-c

Step-by-step explanation:

we are given

y=4(3)^x

we will verify each options

option-A:

we can see that exponent is over 3

and it is positive and greater than 1

so, this function is increasing

so, this is FALSE

option-C:

At x=1:

y=4(3)^1

y=12

At x=2:

y=4(3)^2

y=36

\frac{y_2}{y_1} =\frac{36}{12}

\frac{y_2}{y_1} =3

y_2=3y_1

So, it is getting tripled

so, this is TRUE

option-b:

we can plug x=0

y=4(3)^0

y=4

so, this is FALSE

option-d:

we can plug x=1

y=4(3)^1

y=12

so, this is FALSE

A family has two cars. the first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of
tatyana61 [14]
Let's call the fuel consumption of the first car "x" and the second car "y"
x + y = 35 is the total fuel consumed.
20x + 25y = 775 is the distance traveled.
Solve the two equations. Skipping a few steps, I get 
5y = 75. Therefore y = 15. So y used 15 gallons of gas. Therefore x used 20 gallons.

20 gallons, 15 gallons.
