3y-4=6- 2y
y=?
solve pleaseeeeeeeeeee

Answers

Answer 1

Answer:

y=2

Step-by-step explanation:

3y - 4 = 6 - 2y –––Add 2y from both sides

5y - 4 = 6 –––Add 4 to both sides

5y = 10 –––Divide both sides by 5 to get y alone

y = 2

Check:

3(2) - 4 = 6 - 2(2)

6 - 4 = 6 - 4 (You could probably tell they are equal by here)

2 = 2 (You should definitely tell they are equal here)

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.

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

Answers

Exact Form:

x=-3/2

Decimal Form:

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
