X^5 + 4x^3 - 5x
= x(x^4 + 4x^2 - 5)
= x (x^2 + 5)(x^2 - 1)
= x( x + 1)(x - 1)(x^2 + 5)

there are 3 real zeroes and 2 complex zeroes.

The system of equations is graphed on the coordinate plane. y=−12x−1y=14x−4 A graph with a blue line passing through coordinates

Anika [276]

We have that

case 1)
system of equations is
y=−12x−1
y=14x−4

using a graph tool
see the attached figure

the solution of the system is the point (0.115,-2.385)

case 2)
system of equations is
blue line passing through coordinates A (0, -4) and B (4, -3)
red line passing through coordinates C(0, -1) and D (4, -3)

using a graph tool
see the attached figure

the solution of the system is the point (4,-3)

What is the solution to the following system of equations? x+y=5 x-y=1 step by step

Andreas93 [3]

x+y=5
-x -x

Equals:

y=-x+5

Now you have:

y=-x+5
x-y=1

Insert -x+5 into y

x-x+5=1

Combine like terms

2x+5=1

Subtract 5.

2x=-4

Divide 2.

Answer: x=-2

In the seahorse tank at an aquarium, 70% of the male seahorses

lara [203]

Part A: Kennedy's expression is incorrect because 0.07 is 7 percent, not 70.

Part B: The correct expression would be 0.7 * 20, which equals 14

Please help. X= 4 7 9

Sauron [17]

If you look at the circle, the numbers given add up to 11. The interior angles of a circle always add up to 180 degrees. If you add zeroes onto the numbers given they become 30, 20, and 60. These add up to 110. Out of the choices given the only one that would make sense is 7, because if you add a zero onto 7 it becomes 70. 110 + 70 = 180.
Therefore, the answer is 7.

Hope this helps!

Which of the following shows the interval of the domain where

Arte-miy333 [17]

The domain of the function where the function is decreasing is (-∞, 1). Then the correct option is D.

<h3>What are domain and range?</h3>

The domain means all the possible values of the x and the range means all the possible values of the y.

The function is given below.

f(x) = x² - 2x + 5

The equation can be written as

f(x) = x² - 2x + 1 + 4

f(x) = (x - 1)² + 4

Then the domain of the function where the function is decreasing will be (-∞, 1).

Then the correct option is D.

More about the domain and range link is given below.
