Answer:

a = 43 / 30

Step-by-step explanation:

-7 ( 8a -9 ) = -23 + 4a

-56a + 63 = -23 +4a

-60a + 63 = -23

-60a = -86

a = 43 / 30

How many kilometers will Venus travel in 5 second? In you computations, assume that 1 mile is equal to 1.6 kilometers. Do not ro
Kruka [31]
Venus moves at an approximate speed of 78,341 miles per hour, so we need this to be miles per second for our calculations.
First, divide by 60, as this time is for hours, and 1/60 of an hour is a minute.
78,341/60=1305.68333 miles per minute.
Divide this number by 60 to get 1 second, as there are 60 seconds in a minute.
1305.68333/60=21.7613888 miles per second
Now, multiply this by 5 for the total distance over 5 seconds.
21.7613888*5=108.806944 miles in 5 seconds
Now, we need to convert this distance from miles to kilometers, by multiplying this final answer by 1.6.
108.806944 miles*1.6=174.0911 kilometers in 5 seconds.

Hope this helps!
And I do not think any rounding was completed until the end.  I shortened for the display on this, but I used the infinite decimal in the calculator.

Which points are on the graph of g(x)=(1/5)x<br><br> Select EACH CORRECT ANSWER
sdas [7]

If a point is on the graph of the exponential equation then it should be true when you solve.


g(x) = (1/5)^x

y = (1/5)^x


1/125 = (1/5)^3

cbrt(1/125) = 1/5

.2 = 1/5

.2 = .2 YES


5 = (1/5)^-1

5 = 5 YES


1/25 = (1/5)^-2

-2root(1/25) = 1/5

5 = 1/5 NO


0 = (1/5)^1

0 = .2 NO


The correct answers are <em>A and B</em>.
