Answer:
it will take them 3.6 hours if their speed is increased
Step-by-step explanation:
First of all, we will need to find the total distance the Geradi family will be travelling. This is a better way to start, as the distance is constant regardless of their change in velocity.
Distance travelled = speed of travel X time taken = 45 X 4 = 180 miles per hour.
If the Geradi family increases their speed to 50 miles per hour, their new time will be got by dividing the total distance travelled by this new speed.
New travel time = 180 miles / 50 miles per hour = 3.6 hours
Answer:
The function is

The graph is attached.
Step-by-step explanation:
We have a function g(x) and we need to graph a new function that is function of g(x).
The final function is

We start by calculating g(x-2):

Then, we can calculate f(x) as:

Answer:
1/2
Step-by-step explanation:
To find the slope of a line through 2 point we use the formula
m = (y2-y1)/ (x2-x1)
= (9-6)/(-3--9)
= 3 /(-3+9)
= 3 /6
= 1/2
Answer:
A. The domain is (1,∞), and the range is (-7,∞)
Step-by-step explanation:
Well lets graph it first,
Look at the image below ↓
By looking at the image we move it 3 units right and 3 units down.
Then it will be located at the point (1,-7).
Meaning for the domain it starts at 1 and goes on for infinity.
And For the range it starts down at -7 and goes down for infinity.
<em>Thus,</em>
<em>the correct answer is choice A.</em>
