Answer:
Roots (It has a solution)
Step-by-step explanation:
One method to find out whether or not this equation has a solution or not is to try to solve for x..
As we could find a solution, it has a root.
9:20 + 3:00= 12:00
12:00 + 0:50= 12:50 A.M. Tom's afternoon shift begins
Answer:
(15, 11).
Step-by-step explanation:
Given the system of equation;
X=2y-7 ..... 1
4x+y=71 ....2
Substitute 1 into2;
4(2y-7) + y = 71
8y - 28 + y = 71
9y - 28 = 71
9y = 71 + 28
9y = 99
y = 11
Substitute y = 11 into 1;
x = 2y - 7
x = 2(11)-7
x = 22-7
x = 15
hence the solution to the equation is (15, 11).
The radius would be 6. the diameter is the full length from one side of the circle to the other and the radius is just half. divide 12 by 2 and you get 6 :)
