Answer:
cookie=0.5, popcorn=4
Step-by-step explanation:
1x+2y=5
1x+4y=6
cookie cost 0.5
popcorn cost 4
For two lines to be parallel, their slope must be the same.
To find the slope, we can use the form:
For the top line, the change in height (y value) can be seen as a - 0 or simply a, and the change in base is just -b (because our
is just 0, from the origin.
Hence, line 1's gradient is:
Now, we can repeat this process for line 2:
Change in height is -d, change in base is c
Hence, line 2's gradient is:
For the two lines to be parallel, both gradients must be the same:
we know that
The x-intercept is the value of the variable x when the value of the function is equal to zero
so
In the table we have
is a x-intercept, because
For the value of the function is equal to zero
is a x-intercept, because
For the value of the function is equal to zero
therefore
<u>the answer is</u>
the continuous function in the table has two x-intercepts
