Answer:
(-2, 3)
Step-by-step explanation:
For x-4 you go left four places and y+6 go up 6 places
1. Move the negative sign to the left.
- *-50
2. Use this rule: =
-
3. Simplify -
4. Move the negative sign to the left.
-(-950x/8)
5. Simplify 950x/8 to 475x/4
6. Remove parentheses.
To solve the two sets of equations simultaneously, subtract one equation from the other to obtain
3x^5 + 2x^2 - 10x + 4 - (4x^4 + 6x^3 - 11) = 0
3x^5 - 4x^4 - 6x^3 + 2x^2 - 10x - 7 = 0
This is a polynomial of degree 5 to be solved for zeros.
A graphing calculator will yield 3 real zeros (verifiable by Descartes Rule of Signs).
The second graph is correct
1 is 180 - 2(68) = 180 - 136 = 44
2 is
5x + 12 + 3x + 8 = 180
8x + 20 = 180
8x = 160
x = 20
