Answer:
Domain: all real numbers. Range: (-∞, 2000]
Step-by-step explanation:
f(x)=2.5x is a simple "ramp" function, a linear function and a polynomial. As such, its domain contains "all real numbers." That value 800 defines the largest value that this f(x) can have: f(800) = 2.5(800) = 2000.
Thus, the range is "all real numbers from -∞ through and including 2000."
Answer:
Step-by-step explanation:
7x-=6x-9
7x=6x-9
7x+9=6x-9+9
7x+9=6x
7x+6x=9
13x=9
X=0.69
13. (6-9)^-3= -1/27 or -0.04(rounded to nearest hundredth.
15. 4^-1+(5-7)^-2= 1/2 or .5
