Reflection over the x-axis changes the sign of the y-coordinate. Points that were above the axis are reflected to be the same distance below the axis.
Answer:
4(x+1) x (x-2)
Step-by-step explanation:
Answer:
x = -1.
Step-by-step explanation:
√(x + 10) - 4 = x
√(x + 10) = x + 4
Squaring both sides:
x + 10 = x^2 + 8x + 16
x^2 + 8x - x + 6 = 0
x^2 + 7x + 6 = 0
(x + 6)(x + 1) = 0
<u>x = -6, -1.</u>
Check for any extraneous roots:
√(x + 10) - 4 = x
<u>Try x = -6:</u>
√(-6 + 10) - 4 = 2 - 4 = -2.
but we found x = -6 , so -6 is not a root.
<u>Try x = -1</u>:
√(-1 + 10) - 4 = 3 - 4 = -1. So x = -1 is a root.
Descriptive statistics are historically the oldest form of statistics. The brief coefficients that summarize a given data set, this can either be a representation of the entire population or a sample of it. The Descriptive statistics are further broken down into measure of variability and measure of central tendency.
