Answer:
Im not sure but thanks for free point?
Step-by-step explanation:
To find the amount of solutions, you must find the discriminant. The discriminant is b^2 - 4ac. Number 6 has 2 solutions and number 7 has 1 solution.
Answer:
PQ= <em><u>1</u></em><em><u>0</u></em>
Step-by-step explanation:
To find intersection of the line ,put y=0 in the equation,cuz points on x axis have ordinate equals to '0'
you have, y=2x+8 ; put y =0,to find it's intersection to x-axis
i.e, 0=2x+8
i.e, 2x= -8
i.e, x= -8/2
i.e, x= -4
Point P is (-4,0)
again, you have y=2x-12, put y=0
i.e,0= 2x-12
i.e, 2x=12
i.e, x=6
Point Q is (6,0)
now distance PQ is
√(6-(-4))^2 +(0-0)^2
i.e, √(10)^2
i.e, 10
distance btwn PQ is 10 unit!

Step-by-step explanation:
The LKM angle is an enclosed angle. So its size is half the arc facing it.
LKM (angle) = ½ LM (arc)
The LMN angle is a shadow angle. So its size is half the size of the arc facing it.
LMN(angle) = ½ LM(arc)
so:
LKM = LMN
Since all of the side lengths are different, it is a scalene triangle
