What is the solution to the system of equations? {2x+5y=3y=x+2 (1, 3) (−1, 3) (17, 157) (−1, 1)

Step-by-step explanation:

2x + 5y = 3

y = x + 2

2x + 5(x + 2) = 3

2x + 5x + 10 = 3

7x + 10 = 3

7x = -7

x = -1

y = -1 + 2

y = 1

(-1, 1)

a 360 degree rotation

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
