Steps
Step 1: For each (x,y) point calculate x2 and xy.
Step 2: Sum all x, y, x2 and xy, which gives us Σx, Σy, Σx2 and Σxy (Σ means "sum up")
Step 3: Calculate Slope m:
m = N Σ(xy) − Σx Σy N Σ(x2) − (Σx)2
Step 4: Calculate Intercept b:
b = Σy − m Σx N.
Step 5: Assemble the equation of a line.
X + (x + 1) = 7
2x + 1 (-1) = 7 (-1)
2x = 6
2x/2 = 6/2
x = 3
x +1 = 3 + 1
x + 1 = 4
The two integers are 3, 4
hope this helps
Answer:
Step-by-step explanation:
Let
x ---> the number
we know that
The algebraic expression is equal to multiply the number by 4, add 5 and equal 8
so
Solve for x
subtract 5 both sides
Divide by 4 both sides
The answer would be 114. I did 3 times 38 and thats what i got. I hope it helps:D This is from your friendly Tolkien fan.
