Answer:
(b) For each hour that Michelle drove, she traveled an additional 50 miles.
Step-by-step explanation:
Given
---- start
--- end
Required
Which is true
(a): Journey = 6 hours
This is false, because:
---- 7 hours
(b): The average rate is 50 miles per hour
To do this, we calculate the slope (m) using:
This means that the rate is 50 miles driven in 1 hour.
<em>(b) is correct</em>
<em></em>
<em>Others are incorrect</em>
Answer:
D. the answer is a segment
It would be C. y= x+3.
this is because all of them have a slope of 1 because x stands for 1. and then you can tell if it passes through (5,3) because what ever number it is adding or subracting is your Y.
hope this helped out and was correct
Answer:
All real numbers
Step-by-step explanation:
Assuming the polynomial is
Then the domain is all real numbers.
The domain are all values of x, for which the given function is defined.
The reason is that, polynomials are defined everywhere on the real number line.
We can write this as {x|x is all real numbers} .
Or (-∞,+∞)
To find this, first we subtract the extra 3 feet from the original 27 feet.
27-3=24
Then, we divide the left over length by three. This will provide us with the length for the shorter piece.
24/3=8
The shorter piece will be 8 feet long.
Now, we double that to find the longer piece without the additional 3 feet.
8x2=16
And we add those two (8 and 16) together to make sure it is equal to the 24 we divided into 3 earlier.
16+8=24
Now all that's left is to add the extra 3 feet to the 16 feet.
16+3=19
And add that to the 8 feet, to check to make sure the lengths add up to our original 27 feet.
19+8=27
Therefore, the two pieces are the following lengths:
Shorter piece: 8 feet
Longer piece: 19 feet
