Answer:
Step-by-step explanation: x+ y+z=19 ...(1)
2x+6y+z=12 ...(2)
3x+8y+z=-14 ...(3)
(2)-(1) gives
x+5y =-7 ...(4)
(3)-(1) gives
2x+7y= -33 ...(5)
multiply (4) by 2
2x+10y=-14 ...(6)
(6)-(5) gives
3y=19
y=19/3
x+95/3=-7
x=7+95/3=(21+95)/3=116/3
from (1)
116/3+19/3+z=19
(116+19)/3+z=19
135/3+z=19
45+z=19
z=19-45=-26

Step-by-step explanation:
Answer: See the picture attached.
Step-by-step explanation:
Given the following mixed numbers:
You need to convert them to decimal numbers. The steps to do this are shown below:
1. Divide the numerator of the fraction by the denominator.
2. Add the quotient obtained to the whole number part.
Then:
Therefore, the point is:
Where 
is the x-coordinate and 
is the y-coordinate.
Knowing this, you can plot it on the coordinate plane, as you can see in the picture attached.
Answer:
Segment JK is a chord in circle H
Line LM is a secant to circle H
Step-by-step explanation:
* Lets revise some definition in the circle
- The radius of the circle is a line segment drawn from the center of
the circle to a point on the circumference of the circle
- The chord of a circle is a line segment whose endpoints lie on the
circumference of the circle
- The secant is a line intersect the circle in two points
- The tangent is a line touch or intersect the circle in one point
* Now lets solve the problem
- In circle H
∵ JK is a segment in circle H
∵ Point J lies on the circumference of circle H
∵ Point K lies on the circumference of circle H
∴ Segment JK is a chord in circle H
∵ LM is a line
∵ LM intersect circle H in two points L and M
∴ Line LM is a secant to circle H
