The x coordinate is 4. The y coordinate is unknown.
If we substitute 4 for x in the equation, it will look as follows:
Then we simply have to work it out:
So, the second coordinate is
.
Answer:
x = 111
Step-by-step explanation:
126+158+120+125+121+139 = 789
900-789 = 111
(n-2)*180
5*180 = 900
Answer:
2x² - 3x - 8
Step-by-step explanation:
note that (f - g )(x) = f(x) - g(x)
= 2x² - 5 - (3x + 3) = 2x² - 5 - 3x - 3 = 2x² - 3x - 8
8x^2-5x-2
method
open bracket
6x^2-2x-3+x^2-3x+1
collect like terms
6x^2+2x^2-3-3x+1
8x^2-3-3x+1
again collect like terms
8x^2-2x-3x-3+1
8x^2-5x-3+1. (-×-=+ addition but keeping sign minus
8x-5x-2. (-×+=-)
