Answer:
Step-by-step explanation:
x=3 x=2. x=1
y=1 *3 y=1 *2. y=1 *1
y=1 y=1. y=1
(3,1). (2,1) (1,1)
‘The others are the same. Probably you can use a calculator too
Answer:
f(-2x+1)=-x -1/2
Step-by-step explanation:
f(-2x+1)= 1/2 * ( -2x + 1 ) - 1
f(-2x+1)=-x + 1/2 - 1
f(-2x+1)=-x -1/2
Answer:
Step-by-step explanation:
2x - 1 =0
2x = 1
x = 1/2
Now We have to find P(1/2). If P(1/2) is zero, then 2x - 1 is a factor of P(x)
P(x)= x³ - x² + 2x -1
![P(\frac{1}{2})=[\frac{1}{2}]^{3}-[\frac{1}{2}]^{2}+2*[\frac{1}{2}]-1\\\\=\frac{1}{8}-\frac{1}{4}+1-1\\\\=\frac{1}{8}-\frac{1*2}{4*2}+0\\\\=\frac{1}{8}-\frac{2}{8}\\\\=\frac{1-2}{8}\\\\=\frac{-1}{8}\neq 0](https://tex.z-dn.net/?f=P%28%5Cfrac%7B1%7D%7B2%7D%29%3D%5B%5Cfrac%7B1%7D%7B2%7D%5D%5E%7B3%7D-%5B%5Cfrac%7B1%7D%7B2%7D%5D%5E%7B2%7D%2B2%2A%5B%5Cfrac%7B1%7D%7B2%7D%5D-1%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B8%7D-%5Cfrac%7B1%7D%7B4%7D%2B1-1%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B8%7D-%5Cfrac%7B1%2A2%7D%7B4%2A2%7D%2B0%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B8%7D-%5Cfrac%7B2%7D%7B8%7D%5C%5C%5C%5C%3D%5Cfrac%7B1-2%7D%7B8%7D%5C%5C%5C%5C%3D%5Cfrac%7B-1%7D%7B8%7D%5Cneq%200)
2x - 1 is not a factor of p(x)
Hi!
To solve this, we need to understand that 0.6 is multiplied by y, an unknown number, to make 10.3.
So let's rearrange the equation.
10.3/0.6 = y
Does that make sense? Let me know.
Solve:
10.3/0.6 = 17.17
y = 17.17
Hope this helps! :)
You multiply the number by 100.
E.g: 40-40%. 40x100=0.40=40%
