B because it shows more figure
X1,y1 = (-4,-2), x2, y2 = (9-2,-4)
could you check if 9-2 is actually correct, just I never seen it before
Let the difference between consecutive terms be D. If the middle term is 30, then the term before it is 30-D, and the term after it is 30+D. So the sum of these three terms would be (30-D) + 30 + (30+D) = 3*30.
Extending this sum to include all 11 terms centered around 30, we see that any addition of D is canceled by a balanced subtraction, leaving you with 11 copies of 30. So the value of the sum is 11*30 = 330.
Answer:
y-3=1/5(x+2)
Step-by-step explanation:
y-3=1/5(x--2)
the negatives cancel out making it
y-3=1/5(x+2)
Answer:
5×(w + 7) = 4
Step-by-step explanation:
w is the unknown number.
5 times something means multiply something 5 times.
a sum means adding things
so, the sum of a number and 7 is
w + 7
5 times that sum is then
5×(w + 7)
and that while thing is (equals) 4
5×(w + 7) = 4
by the way, solving that means
5w + 35 = 4
5w = -31
w = -31/5
