Step-by-step explanation:
A negative divided by a negative equals a positive, so -8 ÷ -4 = 2
Answer: C. 2n+1
Step-by-step explanation:
The sequence of numbers is
3,5,7,9
The terms are increasing at a linear rate. This means that it is an arithmetic progression. The difference between two successive terms is constant. This is the common difference. The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
Tn is the nth term of the arithmetic sequence.
d is the common difference of the arithmetic sequence.
n is the number of terms in the arithmetic sequence.
From the information given
a = 3
d = 5 - 3 = 7 - 5 = 9 - 7 = 2
Tn = 3 + 2(n - 1)
Tn = 3 + 2n - 2
Tn = 3 - 2 + 2n
Tn = 2n + 1
Answer:
in my opinion i think its c
but somebody else might think different
Answer:
To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates. Do not write the power of ten anymore.
HOPE THIS HELPED!!!!!!!!!!!!!XDDDDDD
