Answer:
x = 8
Step-by-step explanation:
y = 4x - 2
30 = 4x - 2
+ 2 + 2
32 = 4x
/ 4 / 4
8 = x
Answer:
No
Step-by-step explanation:
If (x - 9) is a factor then x = 9 is a root and f(9) = 0
f(x) = 4x³ - 28x² - 36x - 27, hence
f(9) = 4(9)³ - 28(9)² - 36(9) - 27
= 2916 - 2268 - 324 - 27 = 297
Since f(9) ≠ 0 then (x - 9) is not a factor of f(x)
You just need to add them all up
X = 53° + 44° + 46° = 143°
Answer:
Kind of ... any value of x is a solution, but there isn't any unique solution.
Step-by-step explanation:
4(x+1)+x=5(x-1)+9
4x + 4 + x = 5x - 5 + 9
5x + 4 = 5x + 4
