Find out the hours travels by the annie and brian

To proof - Let us assume that the hours travelled by brian be x.

As given in the question Annie traveled 7 times the sum of the number of hours Brian traveled and 4.

So, Annie travelled = 7(x+4)  and Brian travelled = x

Total hours travel by them is 56.

According to question:

x +7 ( x+4) = 56

x+7x +28=56

8x=56-28

x=3.5 hours

Therefore,  Brian travel for 3.5 hours and Annie travels for the 52.5 hours.

Help plzz i will give you brianliest Which best describes the graph of the function f(x) = 3(1.8)^x A) The graph passes through
DanielleElmas [232]

Answer:

Step-by-step explanation:

Start with why C isn't the answer.

y = 1.8^0 . The power is zero. Anything to the zero power (anything except 0 to the 0 power) is 1. So 1.8^0 is 1 not something else. C assumes that somehow 0,1.8 turns into 1.8. It does not. The second part is also wrong but you don't need it. However here it is.

x = 0        y = 3

x = 1         y = 3 * 1.8 = 5.4

x = 2        y = 3 * 1.8^2 = 3*3.24 = 9.72

You should be able to see that if you multiply 5.4 by 3, you don't get 9.72

C just does not work.

=======

The actual answer is A. That's exactly what the graph does. If you multiply 5.4 * 1.8 you should get 9.72. Just for completeness, I've included the graph.

if not, and you are trying to find the zeros is

x=-3

x=0

Step-by-step explanation:

multiply x(x+3)

x^2+3x

then multiply that by x+3 and that should give you the answer
