What are the ordered pairs of the solutions for this system of equations?

( 4, 11 ) , ( - 4, 27 )

Step-by-step explanation:

f(x) = x² - 2x + 3

f(x) = - 2x + 19

x² - 2x + 3 = - 2x + 19

x² - 16 = 0

( x + 4 )( x - 4 ) = 0

= - 4

= 4

f(x) = = - 2( - 4 ) + 19 = 27

= 27

f(x) = = - 2( 4 ) + 19 = 11

= 11

( 4, 11 ) , ( - 4, 27 )

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
