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

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

Answers

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.

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.

Stephano’s marble will get there first because the slope for Stephanos’s marble is y=2.25x, and when you do the math, (6=2.25x), the marble will reach 6 ft. at 2.7 seconds, and the x in y=3/2x for Pete’s marble is 6 ft. after 4 seconds, so Stephano’s marble will reach the 6 ft. mark first.

6/7 is greater than 4/9

Answer:

[tex]\frac{6}{7}[/tex]

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].

Answers

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
