Find the discriminant and the number of real roots for this equation.
4x2 + 12x + 9 = 0
A. -144; one real root
B. -144; no real roots
C. 0; one real root
D. 0; two real roots
Discriminant and the number of real roots for this equation are 0, one real root.
What is discriminant?Discriminant of a polynomial in math is a function of the coefficients of the polynomial.
The discriminant of a quadratic equation ax2 + bx + c = 0 is in terms of its coefficients a, b, and c. i.e.,
Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]
Given equation
[tex]4x^{2} +12x+9 = 0[/tex]
Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]
= [tex]\sqrt{12^{2}-4(4)(9) }[/tex]
= [tex]\sqrt{144-144}[/tex]
D = 0
Therefore, number of real roots is one.
Hence, discriminant and the number of real roots for this equation are 0, one real root.

Step-by-step explanation:
Inequality
Jake is younger then Sophie
Sophie is 14 years old
_______________________
When it comes to inequality, we need to base if off of greater, less, or equal to. We know that Jake is younger than Sophie, therefore he is less in age, meaning that the less than symbol (<) will be used. Since Sophie is 14, he has to be less than 14. Therefore :
j < 14

In your own words, explain what it means for something to be a function (or functioning consistently). Provide an example of a function in mathematics and in the world outside of school. Also explain and provide an example of when something is not a function.
Answer: Look down below
Step-by-step explanation: .Horizontal lines are functions that have a range that is a single value. Vertical lines are not functions. The equations y=±√x and x2+y2=9 are examples of non-functions because there is at least one x-value with two or more y-values.

Step-by-step explanation:
Hope this helps :)
The reason is to release energy into the environment.
the correct option is (C)
What is cell?Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions
As, Exchange of substances between a cell and its environment is mediated through osmosis, active transport and diffusion.
Osmosis is the process of diffusion of molecules from the region of higher concentration to the lower concentration through a semipermeable membrane. The cells absorb water by the process of endosmosis from its surrounding and water exits by the process of exosmosis.
Cells need to move water, materials for energy, waste materials, and other molecules across the cell membrane to help maintain homeostasis.
Also, to release energy into the environment.

-9=-3(x+2)+5x what does x equal
Exact Form:
x=-3/2
Decimal Form:
x=−1.5x
Mixed Number Form:
x=−1 1/2
Answer:
-1.5
Step-by-step explanation:
-9=-3(x+2)+5x (switching the sides of the formula can make it easier)
-3(x+2)+5x=-9
2x-6=-9
add 6 to both sides ---> 2x-6+6=-9+6
simplify ----> 2x=-3
divide both sides by 2 ---> 2x/2 = -3/2
simplify ---> x= -3/2
decimal form- -1.5

Step-by-step explanation:
[tex]\frac{4}{9}or \frac{6}{7}[/tex]
First you need to find a common denominator. so you could just multiply 9 and 7 or you could write the factors of each number.9*7 is 63, so that is your denominator. Multiply top and bottom of [tex]\frac{4}{9}[/tex] by 7 and you should get [tex]\frac{28}{63}[/tex].Multiply top and bottom of [tex]\frac{6}{7}[/tex] by 9 and you should get [tex]\frac{54}{63}[/tex]. Is [tex]\frac{28}{63}[/tex] or [tex]\frac{54}{63}[/tex] bigger?[tex]\frac{54}{63}[/tex] is bigger so your answer would be [tex]\frac{6}{7}[/tex].Hope this helps :)
