If X is 5
Then f(5) = 3(5) + 2
= 17
Answer:
The number of solutions to the given set of equations is 0.
Step-by-step explanation:
Number of solutions of a system of equations:
System of equations: ax = b
If a = 0 and b = 0, infinite solutions.
If a = 0 and b != 0, zero solutions.
If a != 0 and b != 0, one solution.
We are given the following system of equations:
y = 7x + 12
y = 7x + 2
So
7x + 12 = 7x + 2
7x - 7x = 2 - 12
0x = -10
a = 0, b != 0, so zero solutions.
The number of solutions to the given set of equations is 0.
Answer:
43
Step-by-step explanation:
you change the 1 hour into minute you and 60min to 25 minutes and then you subtract from 42 minutes to get the solution
280*3= 840
3 journals is about 840 grams
