Answer:
D
Step-by-step explanation:
If a function has x in the denominator, it cannot be a polynomial.
The rest of the options either don't apply to the equation, or are not rules for polynomials.
Mean is 11.3 and the range is 4. Dont need to add 5 for all. Just do mean for the given options and add 5 at the end. Same with the range 9-5=4. Doesn’t change when you add 5 for all
C
Answer:
y=75x+50
y=600
x=3
Step-by-step explanation:
since at x=zero the y=50
then let y=nx+50
since at x=2 y=200, 200=2n+50, 2n=150, n=75
then y=75x+50
at x=8
y=75×8+50=600+50=600
at y=275
then 75x+50=275, 75x=225, x=225/75=3
Once you have the points they make a 3-4-5 triangle. The two legs are 3 and 4, so the hypotenuse has to be 5. Or you could use the pythagorean theorem a² + b² = c² 3² + 4² = c² 25 = c² c = 5
then find area
A=1/2bh
1/2(3*4)
6
1/4 as you can divide the fraction by 5,
