Writing equivalent equations help you solve system of equations because it sets it up for being broken down part by part.
20 it the least common multiple of the numbers given
(7 + i) - (6 - 2i) = 7 + i - 6 + 2i = 1 + 3i
Answer:
the 4th answer I(x) = P(x-4)
Step-by-step explanation:
the first 2 options are out, because just adding values to the functional result values changes the y value, and the curve is pushed up or down. but not to the side.
just imagine
I(x) = P(x-4) means that the function value of previously at x-4 happens now at x. 4 units "later" (or more to the right).
"x+4" would make the functional value at previously x+4 happen now at x. so, everything would shift to the left (happen "earlier").
therefore, the 4th answer option is correct.
The shape has 9 sides.
Sum of interior angles = (n-2) x 180, where n is the number of sides.
Sum of interior angles = (9-2) x 180 = 7 x 180 = 1,260 degrees.
