Answer: Yes, it is a real number. 3.4 is a rational number and rational numbers are real numbers. So 3.4 is a real number.
Solution:
Average time per line = total time / total lines
Average time per line = (3x^2 + 2)/(x + 4)
Average time per line = 3x - 12 + (3x^2 + 2)/50 milliseconds
Please, for clarity, indicate exponentiation using the " ^ " symbol.
y = - 3x^5 ("Negative three times the 5th power of x")
y = 3x^8
y - -3(0.5)^x
y = -2^4
An exponential function has an exponent which is variable, where the base stays constant; the base cannot be a negative number or a zero. The third answer choice is the correct one, as we raise the constant 0.5 to the power x:
y = -3(0.5)^x
Step-by-step explanation:
y = ⅓x − 2
y = -3x − 12
The first line has a y-intercept of -2 and a slope of ⅓.
The second line has a y-intercept of -12 and a slope of -3.
