Answer:
-8
Step-by-step explanation:
1. x + 23 = 15
2. x + 23 = 15
-23 -23
3. x = -8
(-8.6)+7.2= -1.4
Think of it as 8.6-7.2 and carry down the negative sign.
Answer:
the scientific name is the same name around the world and if you use common names they are different around the world
Step-by-step explanation:
Answer:
f = -5
Step-by-step explanation:
If 2x – 1 is a factor of 16x4 + 24x3 + 2x + f, find f.
If 2x - 1 = 16x⁴ + 24x³ + 2x + f, find f.
2x - 1 = 0
2x = 1
x = 1/2
Hence
f(1/2) = 16(1/2)⁴ + 24(1/2)³ + 2(1/2) + f
= 16(1/16) + 24(1/8) + 1 + f
= 1 + 3 + 1 + f
= 5+ f
f = -5
