This is how I believe it would look like
Answer:
The Variables are X & Y
The Coefficients are 1/4 & 3
and the Constants are -23 and 42
Step-by-step explanation:
it's correct on edge!
Given:
(3x^4 - 2 + 8x^3 ) + (7x^3 - 6 + 7x^4 )
Add like terms together ( same variables and exponents )
3x^4 + 7x^4 +8x^3 + 7x^3 -2 - 6
10x^4 + 15x^3 - 8
Answer :
10x^4 + 15x^3 - 8
The answer is C (-2.2, -3).
In order to find the ordered pair we must use what we know from the first equation in the second. We already know that y = -3, so that goes into the second equation.
y = x - 0.8
-3 = x - 0.8
-2.2 = x
