Because ab is not negative but c has the negative sign in front of it
Answer:
(2,-2)
Step-by-step explanation:
To solve this using substitution you would take your second equation and plug it in for y of the first equation (4x-10= -3x+4). You then would add the 10 over (4x= -3+14). Next you add the 3x over(7x=14). Finally divide both sides by 7, which should give you x=2. Now all you have to do is plug the two in for x in one of your equations (which ever equation you prefer) (y=-3(2)+4). Solve the equation and you will then have the answer to y, which you can then put into a point.
You have to take the amount of money payed, which in this case is 45.50, and divide it with 7.
Answer: In degrees , The measure of 
In radians , the measure of
.
Step-by-step explanation:
We know that the formula for length of arc is given by :-
, where
= Central angle subtended by arc.
r= radius of the circle.
As per given , we have
Radius of circle : r=7 m
Length of arc : l= 8 m
Substitute these values in the above formula , we get
Hence, the measure of
.
To convert it into degrees we multiply it with 
The measure of 


Hence, the measure of
