Explain how algebra tiles represent like terms and zero pairs

1 answer:

7 0

Well if you have a problem like -6 + 7, then you can use one color of algebra tiles(atls) for the negative and another color for positive. Take yellow for negative and red for positive for an example. You have 6 yellow and 7 reds. You want to make as many pairs of one red and one yellow. You can make a total of 6 pairs and a red left over. Since red is positive an there is only one, your answer is 1.

Hope i helped

The value of a weight vector is given as (w1=3, w2=-2, w0=1) for a linear model with soft threshold (sigmoid) function f(x).

dolphi86 [110]

Answer:

Please see explanation for the answer. The code is written in python and is as given below:

Step-by-step explanation:

The solution is obtained on the Python with the following code

import matplotlib.pyplot as plotter

import numpy as npy

x_s = npy.linspace(-5,5,100) #Defining a linear sample space with boundaries as -5 to 5 and 100 as number of samples.

def sigmo(z):return 1/(1 + npy.exp(-z)) #Defining sigmoid function for the f(x).

plotter.plot(x_s, sigmo(x_s))

plotter.plot([-5,5],[.5,.5])

plotter.xlabel("z")

plotter.ylabel("sigmoid(z)")

plotter.show()
