Ok because what does this even mean
Answer:
y = - 5x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 5x + y = 4 into this form by subtracting 5x from both sides
y = - 5x + 4 ← in slope intercept form
with slope m = - 5
Parallel lines have equal slopes, thus
y = - 5x + c ← is the partial equation
To find c substitute (- 1, 4 ) into the partial equation
4 = 5 + c ⇒ c = 4 - 5 = - 1
y = - 5x - 1 ← equation of line
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
