Answer:
(1, 0 )
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x =
, then
y =
(x + 2) - 1
to find the zero let y = 0 , that is
(x + 2) - 1 = 0 ( add 1 to both sides )
(x + 2) = 1 , then
x + 2 =
= 3 ( subtract 2 from both sides )
x = 1
the zero is (1, 0 )
Answer:
8 is the number
Step-by-step explanation:
3x8= 24
24-9 is 15
Answer:
{-3/2, 4}
Step-by-step explanation:
Use synthetic division here. If the remainder is 0, then the divisor is a root or solution.
Here we have x = -4. Perform the synthetic division as follows:
-4 4 -10 -24
-16 108
------------------------------
4 -26 84 The remainder is 84, which tells us -4 is NOT
a root/solution.
Try -3/2 as divisor this time:
-3/2 4 -10 -24
-6 24
------------------------------
4 -16 0 Remainder is 0, so -3/2 is a solution
Show in the same manner that 4 is a solution also. Or determine whether x - 4 satisfies 4x - 16 = 0 (it does).
