Answer:
26.20 + 0.35m ≤ 200
Step-by-step explanation:
Let m = number miles of the driven
Given
$26.20 is the initial
Every mile cost $0.35
We have :
26.20 + 0.35m ≤ 200
Answer: ( X- k )(3x2 - 4x + 7) + 1
Step-by-step explanation: Please find the attached files for the solution
Use the rational root theorem
a0=16, an=1
The dividers of a0: 1,2,4,8,16 The dividers of an:1
Therefore check the following rational numbers: +- 1,2,4,8,16/1
4/1 is a root of the expression, so factor out x-4,
compute (x^4+13x^3-64x^2-20x+16)/(x-4) to get the rest of the equation:
x^3+17x^2+4x-4
=(x-4)(x^3+17x^2+4x-4)/x-4
which will leave you with answer B
x^3+17x^2+4x-4
4 + (-7)
add its opposite
4 - 7
which is negative 3
4 + (-7) = -3
88=2(4b+6)-4
88=8b+12-4
88=8b+8
-8 -8
80=8b
80/8=10b
