Answer:
Step-by-step explanation:
So the point-slope formula looks like this: 
= any y point on the line
= any x point on the line
= the slope
And hey, look, we're already given all that information!
So we can just plug those values into the equation:
(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
Answer:
≈ 14.6
I'm assuming that says use 3.14 as radius, because it's cut off
What is the slope of the line that passes through the points (1, 3) and (5, –2)?
C.-5/4
slope = (-2 -3)/(5 -1) = -5/4
2.The sum of two consecutive odd integers is 80. What is the smaller number?
C.39
odd : 39 +41 = 80
39 is the smaller odd number
Answer:
3900
Step-by-step explanation:
We want the sum from 5 to 195
5, 10, 15, 20,......195
an = 5 + 5(n-1) since we can write this as an arithmetic sequence, adding 5 each time
The sum of the terms of an arithmetic sequence is given by
Sn = n/2 [2a1 + (n - 1)d],
where d is the common difference of 5 and n is the term we want to add to
195/5 = 39 so it is the 39th term
s39 =39/2 [2*5 + (39-1)*5)]
s38 = 19.5[10+38*5]
=19.5*[10+190]
19.5*200
=3900
Answer:
0 the answer is zero
Step-by-step explanation:
add 2 to -2 and you get 0
