What is the solution to this system of equations?

C. Infinite solutions

Step-by-step explanation:

2x+4y=-2

3x+6y=-3

3(2x+4y=-2)

-2(3x+6y=-3)

6x + 12y = -6

-6x - 12y = 6

This is zero, meaning infinite solutions.

C

Step-by-step explanation:

Add -4y to both sides

2x+4y-4y=-2-4y

2x=-4y-2

x=-2y-1. Now you substitute this to the second equation.

3(-2y-1)+6y=-3

-6y-3+6y=-3

-3=-3, so now add 3 to both sides

0=0, so infinite solutions.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
