Which ordered pair (a, b) is the solution to the following system of equations?

Kamila [148]

Answer:

(-13, -4)

Step-by-step explanation:

It is about as easy to try the solutions as it is to find them from scratch.

However, we can determine which one it is by adding twice the second equation to the first.

(-2a +3b) +2(a -4b) = (14) +2(3)

-5b = 20

b = -4 . . . . . . matches the first choice

The length of XY the minor arc is 48 cm what is the circumference of Z

Amanda [17]

If found the image that accompanies this problem, the central angle was 60°. Since the circumference of a circle is always 360°, the minor arc represents 60°/360° of the circle.

48 cm / (60°/360°) = 48 cm / (1/6) = 48 cm * 6/1 = 48 cm * 6 = 288 cm

The circumference of circle Z is 288 cm.
