Answer:
x = -5, 1
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from
.
-1 and 5 multiply to -5 and add to 4.
![x^2+4x-5 = (x+5)(x-1)](https://tex.z-dn.net/?f=x%5E2%2B4x-5%20%3D%20%28x%2B5%29%28x-1%29)
The zeros are the factors set equal to 0 and solved.
(x+5) = 0
x=-5
(x-1) = 0
x=1
Answer:
Good morning! Number of trials are 250.
Step-by-step explanation:
A researcher finds 50% of all commuters in a metropolitan area take the train to work.
The researcher polls 250 people in the area to ask them whether they take the train to work or not.
We have tell the number of trials for this binomial experiment.
Researcher will do 250 trials to confirm whether they take the train work and this irrespective of their response.

Answer:
Well there is no linear equation that represents y as a function of x. You said it yourself, "The data CANNOT be modeled by a linear equation because the rate of change is not constant."
Step-by-step explanation:
There is none. y has random values.
Too easy
remember all angles in traingle add to 180
straight lnes are 180
so
35+59+x=triangle
35+59+x=180
x=86
x+y=line
x+z=180
86+z=180
z=94
11+z+y=triangle
11+94+y=180
y=75
x=86
y=75
z=94
yah, 2nd one
Step-by-step explanation:
x+10=116
x=116-110
=106
x=106
