Answer:
Number 7 is 48
I think number 5 is 49 I'm not for sure about this one.
Step-by-step explanation:
Number 7:
Since it's a 90 degree angle, you just add 19 + 23 which gives you 42. Subtract 42 from 90 and it gives you 48, the value of the variable.
Number 5:
Now I'm not for sure about this one because of the number 12 pointing to the connecting point. So, I'd rather not say how I did this one before I get you confused when you learn about this in the future.
Answer:
The lines coincide
The slopes are equal
The y-intercepts are equal
The system has an infinite amount of solutions
Step-by-step explanation:
If you convert both equations into slope-intercept form, you will be able to see that both are y = 5/2x -3. When both lines are the same, it means that they are the same line and they have an infinite amount of solution. If they are the same line, it also means their slopes and y-intercepts are same as well. Thus, you have your derived answer.
Bill's Statement is Sometimes true.
Bill's statement is only true if 1 or both of the variables are positive but if both r and s are negative then it will be located on the left of r. Ex. r=-1 s=-2 (-1)+(-2)=-3
