4x + y = 12
Get y by itself
Subtract 4x
y = -4x + 12

Since you know what y is, you can plug the value into the second equation

6x + 2(-4x + 12) = 18
6x - 8x + 24 = 18
-2x = -6
x = 3

Plug the value 3 into x for y = -4x + 12 in order to find y
-4(3) + 12 = y, y = 0

Solution: x = 3, y = 0

The shape of Colorado is nearly a rectangle. The width is 100 miles less than the length. The perimeter is
lilavasa [31]

Answer:  width = 280 miles, length = 380 miles

<u>Step-by-step explanation:</u>

width: L - 100

length: L

Perimeter = 2(Length) + 2(width)

      1320 = 2(L)            + 2(L-100)

      1320 = 2L              + 2L - 200

      1320 =           4L            - 200

      1520 =           4L

       380 =              L

width: L - 100 ---> 380 - 100 = 280

length: L        ---> 380

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
