The slope is the change in Y over the change in X
With the given points, the first number inside the parenthesis is the X values and the second number is the Y values.
Slope = (Y2 - Y1) / (x2-x1)
Slope = -5 - 3 / 4 - (-6)
Slope = -8 /10
Slope = -4/5
Answer:
(c) n(n+1)/√2
Step-by-step explanation:
√2+√8+√18+√32+...
1√2+2√2+3√2+4√2+...+n√2
- First term= √2
- Common difference= √2
- Sₙ= n/2(2√2+(n-1)√2)= n/2(n√2+√2)=n(n+1)√2/2= n(n+1)/√2
Option (c) is correct
3 1/4 inches long,
1/2 inch in 1 month1 inch in 2 months
The answer is, 3 1/4 inches + 1 inch = 4 1/4
Y = 3x -1. Y = 3x - 1
(-3) Y = x - 7. -3y = -3x + 21
-2y = 20
-2. = -2
Y = - 10
Y = 3x - 1
-10 = 3x - 1
+ 1. + 1
-9. = 3x
3. 3
-3 = x
(-3,-10)
