notice, the first term is 9.5
from there it goes to 11.5, well, how much is it being added to get 11.5?
well 9.5 + 2, is 11.5, so it was added 2 to 9.5
then it goes from 11.5 to 13.5, namely, 11.5+2 = 13.5
and then 13.5+2 = 15.5 and so on
so, the "common difference" or the common addition value, is 2
how do you find the nth term?
well
Answer: y = 0.45x + 21
Step-by-step explanation:
let x represent the number of minutes used in a month.
Let y represent the monthly cost for x minutes.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (304.5 - 183)/(630 - 360)
m = 121.5/270 = 0.45
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = y intercept
m = slope
To determine the y intercept, we would substitute x = 360, y = 183 and m = 0.45 into y = mx + c. It becomes
183 = 0.45 × 360 + c
183 = 162 + c
c = 183 - 162
c = 21
The equation for the monthly cost is
y = 0.45x + 21
Answer:
some occasions yes and other no for example if a fraction was 3/9 the numerator is prime but the fraction can still be simplified to 1/3 but a number were 3/5 then you wouldn't be able to simplify it
Answer:
C. -2
Step-by-step explanation:
Since the leading coefficient is 1 and rational roots are of the form ...
±(divisor of the constant)/(divisor of the leading coefficient)
all of the possible rational roots must be whole number diviors of 12. The only one on the list is -2.
