-4 and 4
Step-by-step explanation:
Answer:
Step-by-step explanation:
The common difference (d) can be found using the first and 4th terms:
a1 = 3
a4 = a1 +d(4 -1)
-9 = 3 +3d . . . . . simplify
-3 = 1 + d . . . . . . divide by 3
-4 = d . . . . . . . . . subtract 1
Then ...
x = a1 + d = 3 -4 = -1
y = x + d = -1 -4 = -5
The values of x and y are -1 and -5, respectively.
The sum of the digits of a two-digit number is 11. when the digits are reversed, the number increases by 27. find the original number.
13x = 8x + 10
5x = 10
x = 2
AM = 13(2) = 26
Since AM is half of AB,
AB = 26+26 = 52
AB = 52
Answer:
4
Step-by-step explanation:
The Fundamental theorem of algebra states that a polynomial of degree n has n roots, some may be complex.
f(x) =
+ 5x³ + 2x + 6 ← is a polynomial of degree 4
Thus there are 4 possible roots
