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

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.

-9=-3(x+2)+5x what does x equal

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

whats bigger 4/9 or 6/7

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].
