3.1(p - 2.7) simplified:= 3.1p-8.37
Answer:
Step-by-step explanation:
Looking at the given graph, the slope of the line is expressed as
Slope = (y2 - y1)/(x2 - x1)
y2 = 19.5
y1 = 9.5
x2 = 6
x1 = 1
Slope = (19.5 - 9.5)/(6-1)
Slope = 10/5 = 2
The successive terms is increasing by 2
The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a is the first term of the sequence
n is the number of terms in the sequence.
d is the common difference.
From the information given,
a = 9.5
Tn = an
d = 2
The explicit rule for the arithmetic sequence will be
an = 9.5 + 2(n-1)
18 times .031 is .558
18 dollars minus .558 cents is 17.442
Answer is he was maki 17.442 dollars before the increase
Complementary angles mean the angles add up to 80 and Supplementary angles mean the angles add up to 180. So 120 doesn't have those kinds of angle pairs. The only combo i can think of is 40,40,40.
