Answer:
and
Step-by-step explanation:
We have been given that about 75,000 people visit Paris, France. We are asked to write two equivalent expressions that could be used to find the number of people that visits over a 5- day period .
To find the number of people over a 5-day period, we will multiply 75,000 people by 5 as:
Commutative property of multiplication states that we can multiply numbers in any order.
Upon switching the order while multiplying, we will get:
Therefore, our required equivalent expressions would be and
.
Answer:
The solution of this system is
(4). (6.0,5.4)
Step-by-step explanation:
First we have to find the equation of the line represented in the table; for that we have to find it's slope and it's y-intercept
and then write it in the following form:
The slope of the line we get from first two points:
thus we have
we find by putting the point
into the function:
Thus we have
Now we have to find where this line intersects with ; to do this we just substitute
with
:
<em>We have the x-coordinate of the intersection.</em>
We find the y-coordinate by substituting into
:
Thus the solution to the system is
which is option 4.
