Answer: -72m
Step-by-step explanation:
Simplify
A1 = first term
a1 = 15
---------------------------------------------
d = common difference
d = (second term) - (first term)
d = a2 - a1
d = 9-12
d = -3
The negative common difference indicates that the terms are decreasing
Each time we subtract 3, or add -3, to get the next term.
----------------------------------------------
nth term of arithmetic sequence
an = a1 + d(n-1)
an = 15 + (-3)(n-1)
an = 15- 3n + 3
an = 18 - 3n
Answer is choice D
Answer:
Decimal: 0.23
Fraction: 23/100
Percent: 23%
Step-by-step explanation:
In this case, one whole is 100. This is because there are 100 little squares in the one big square.
The amount of shaded squares is 23.
This can be represented as the fraction 23/100. 23/100 is the same as 23 being divided by 100. 23 divided by 100 is 0.23 (our decimal). To find a percent, move the decimal point to the right 2 times. Our percent is 23%.
x is greater then or equal to 250
Plug into y-y1=m(x-x1). So y+5=2/3(x-1). Simplified this equals y+5 =2/3x-2/3. Which then equals y=2/3x+4 1/3
