The x axis is a horizontal line that intersects the y axis at the origin
in an ordered pair, x is the first number
I is true because they do intersect at the origin
II is false because x axis is horizontal
III is false because x is the first number
IV. is true because it is horizontal and it does pass through the origin
I and IV are true
Answer:
5
Step-by-step explanation:
- The ones with the x always go on the left side and the ones without x always go on the right side.
- Every time they change side + changes into - and the other way around.
So now it looks like this 7x + 6x = -42 - 23. When you solve 7x +6x and - 42- 23 it should look like this 13x = -65 now all you need to do is to divide 65 with 13 and you'll get x = 5.
I hope this helps :)
I believe by the first equation they are referring two a representation of the total amount of money made up by the two types of coins. I found this to be 0.05x + 0.10y = 3.50
In my work I solved for the amount of each coin- I assume this is what the final step of your problem entails. If you need any help understanding/ I misinterpreted something please feel free to comment and ask :)
#5c coins or x= 36
#10c coins or y= 17
Answer:
Step-by-step explanation:
The minimum value of sinx is -1 when x = 3π/2, 7π/2, ...
In [2π, 4π), x = 7π/2
