If they take 5 days to drive 679 miles to Seattle. Then the number of miles that they drive each day will be 135.8 miles per day.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
They take 5 days to drive 679 miles to Seattle.
Then the number of miles that they drive each day will be
→ 679 / 5
→ 135.8 miles per day.

Answer:
It would be the first answer.
Step-by-step explanation:
y=-2x^2+4x-2
y=-2(-1)^2+4(-1)-2
y=-2(1)-4-2
y=-2-4-2
y=-6-2
y=-8
(-1,-8)

Answer: (3,1)
Step-by-step explanation: You put y over x and then you simplify it like a fraction and put it back in the form of a coordinate point
Answer:
The exponential model is
.
Step-by-step explanation:
The exponential model can be modelled by the following mathematical expression:
(1)
Where:
- Independent variable.
- Dependent variable.
- Coefficients.
If we know that
and
, then we get the following system of equations:
(2)
(3)
If we divide (3) by (2), we calculate the value of
:



And by (2), we determine the value of
:


The exponential model is
.
Hello there!
Yes, your solution is correct! A way to check it is replacing the value you found for x into x in the equation.
3(2-x) = 7 - 4x ⇒ 3(2-1) = 7 - 4(1)
And now solve 3(2-1) = 7 - 4(1).
3(1) = 7 - 4(1)
3 = 7 - 4
3 = 3
Since it is a true statement that 3 is equal to 3, it means your solution of x = 1 is correct. Good job! :)
