Insert 3x - 7 for y in 15x - 5y = 14
15x - 5(3x - 7) = 14
15x - 15x + 35 = 14
0 = -21
There is no solution.
X^4+ 3x^3+4x^2-8 | x+2 = x^3+x^2+2x-4
-x^4-2x^3
-----------------------
x^3+4x^2-8
-x^3-2x^2
-------------------------
2x^2-8
-2x^2-4x
--------------
-4x-8
4x+8
----------------------------
/ /
is a factor because (x+2)(x^3+x^2+2x-4)=x^4+3x^3+4x^2-8
37.5% i believe! i’m not reallt sure if this is correct; but i believe it is. hope this helps!
Answer:
$16.10
Step-by-step explanation:
Simply take the original cost and multiply it by the percentage to get the tip amount then add it all together.
14 × 15% = 2.1
14 + 2.1 = 16.1
This means the haircut would cost a total of $16.10.
