PLEASE HELP!! Factor completely. (y^2x) - (y^x) - 20

1 answer:

4 0

$y^{2x} - y^{x} - 20$
$y^{2x} + 4y^{x} - 5y^{x} - 20$
$y^{x}(y^{x}) + y^{x}(4) - 5(y^{x}) - 5(4)$
$y^{x}(y^{x} + 4) - 5(y^{x} + 4)$
$(y^{x} - 5)(y^{x} + 4)$

Find All numbers whose absolute value is 2

Elanso [62]

Answer:

Step-by-step explanation:

Absolute Value. Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative. The absolute value of 2 + 7 is 5.

Has two solutions x = a and x = -a because both numbers are at the distance a from 0. ... An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.

Which statement describes the end behavior of the exponential function f(x) = 2x – 3?

charle [14.2K]

The correct answer is:

As x→-∞, y→-3.
As x→∞, y→∞.

Explanation:

As our values of x get further into the negative numbers, the value of 2ˣ will approach 0. This is because raising a number to a negative exponent "flips" the number below the denominator and raises it to a power; we end up with smaller and smaller fractions, eventually so small that they nearly equal 0.

This will make the value of the function 0-3=-3.

As x gets larger and larger (towards ∞), the value of y, 2ˣ, continues to grow as well. Since it continues to grow exponentially, we say the value approaches ∞.

Some friends plotted the locations of their house on a map. brianna's house is at (1,6), Jordan's house is at (5,3). What is one

Rufina [12.5K]

Let
A (1,6)------> location brianna's house on a map
B (5,3)------> location Jordan's house on a map

we know that
One possible path from brianna's house to jordan's house it's a straight line ( the shortest distance)

using a graph tool
see the attached figure

find the distance points AB
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3-6)²+(5-1)²]----> d=√[3²+4²]
d=√25----> d=25 units

the distance from brianna's house to jordan's house is 25 units
