There you go. Hope this helps.
Answer:
(11, 13)
Step-by-step explanation:
Carolyn's work is incorrect. Below is the correct solution:
Given:
----› Equation 1
-----› Equation 2
Substitute y = (x + 2) in equation 1
----› Equation 1
(substitution)
(distributive property)
[Note: this is where Carolyn made a mistake]

Collect like terms

(addition property of equality).

Substitute x = 11 in equation 2
-----› Equation 2
(substitution)
✅The solution to the system of equations would be:
(11, 13)

The system has one solution so it's
A. consistent and independent.
Two correct answers:
9 + x
x + 9
Or you can say
x - -9
or
9 - -x
[] Similar
-> The triangles are similar because they were "mirrored" by the...
[] SSS
-> ... by the SSS similarity theorem, the sides are...
[] Proportional
-> ... the sides are proportional.
[] AB/AC
-> Since the sides are proportional, dividing corresponding sides will leave us with the same number
[] For the last two I think I am missing some information as I do not have any numbers and know where they got 85 from.
Have a nice day!
