Answer:
the correct answer is d
Step-by-step explanation:
Answer:
(0, y) with slope 225 and reaches (8, 4580)
slope is (4580-y)/8=225
so 4580-y=1800
y=2780
(0, 2780) has a y-intercept of $2780
the other function is y=56x+1456+1400
y=56x+2856
the y-intercept here is at (0. 2856), so the other function has the smaller y-intercept.
Step-by-step explanation:
My guess: The distance covered was 44 units and the average speed was 4.
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
