Answer:
one
Step-by-step explanation:
they meet at only one point, thus their system of equations has as solution only those coordinates.
A function assigns the value of each element of one set to the other specific element of another set. The total amount of credit cards opened at the two locations is given as 45+3t.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given that the number of credit cards, A, that is opened t months since January can be modeled by the function A(t) = 20 + 4t, while the number of credit cards opened at another location, B, is defined by the function B(t)=25−t.
Now, the total number of credit cards that are opened at both the location together will be,
Total number of credit cards = A(t) + B(t)
= 20 + 4t + 25 - t
= 20 + 25 + 4t - t
= 45 + 3t
Hence, the total amount of credit cards opened at the two locations is given as 45+3t.

Answer: 156 miles
Step-by-step explanation:
First, divide 936 by 3 that is 312.
Then, do 3 times 2 because they stoped two times everyday that is 6.
Next, divide 936 by 6 that is 156.
Finally, do 312-156 that is 156.
156 miles is the answer
Answer:
-14
Step-by-step explanation:
a·b = |a|×|b|×cos(angle between them)
= 4×7×(-1/2)
= -14
