Answer:
D. R(x)=850x+9600
Step-by-step explanation:
Use the given information as points on a line, and find the slope.
The two given points are (10, 18,100) and (20, 26,600).
slope = (difference in y)/(difference in x)
slope = (26,600 - 18,100)/(20 - 10)
slope = 8,500/10
slope = 850
Only choice D. has a slope of 850.
Answer: D. R(x)=850x+9600
It is the right answer........
I believe the answer is C
To expand the given expression we proceed as follows:
(6x²-2x-6)(8x²+7x+8)
=6x²(8x²+7x+8)-2x(8x²+7x+8)-6(8x²+7x+8)
=48x⁴+42x³+48x²-16x³-14x²-16x-48x²-42x-48
putting like terms together:
48x⁴+(42x³-16x³)+(48x²-48x²)+(-16x-42x)-48
=48x⁴+26x³+0x²-58x-48
hence the answer is:
48x⁴+26x³-58x-48
