Answer and  Explanation:

A mathematical inequality refers to the relation of order that is established between values that are different. This means that one value can be greater or less than another, but not identical. for example:

  • a < b, which is defined as a relation in which the first element is less than the second;

  • a> b, which implies that the first element is greater than the second.

Geometrically this equation:

y> 5x-2

Represents a line, so, according to the previous definition, all possibles values of y must be greater than 5x-2, in another words, all values above the line. In interval notation:

(5x-2, \infty)

I attached you two plots of this inequality

Which expression has a sum of a 11/12? pls help. explain step by step in a way a 13 year old will understand.
lana66690 [7]

c. they are all parts of 12, and when added together they equal 11/12. The formula to solve non proportionate fractions*or with different denominators* is to CROSS multiply and make the denominators equal, then add the numerators and SIMPLIFY.

*Cross multiply to make the denominator equal (you can google how to make fractions equal)

then add the numerators together

then simplify. PLEASE BE CONSIDERATE OF THE FORMULA AND DONT BE INTIMIDATED BY THE LOOK OF THE PROBLEM. They all have the same formula or method of solving. Good Luck!! I hope this helps.

(a) Use the fundamental theorem of algebra to determine the number of roots for 2x^2 + 4x + 7
zysi [14]

Answer:

Step-by-step explanation:

A 2nd order polynomial such as this one will have 2 roots; a 3rd order polynomial 3 roots, and so on.

The quadratic formula is one of the faster ways (in this situation, at least) in which to find the roots.  From 2x^2 + 4x + 7 we get a = 2, b = 4 and c = 7.

Then the discriminant is b^2 - 4ac, or, here, 4^2 - 4(2)(7), or -40.  Because the discriminant is negative, we know that the roots will be complex and unequal.

Using the quadratic formula:

       -4 ±√[-40]         -4 ± 2i√10

x  = ------------------ = ------------------

                4                       4

                                       -2 ± i√10

Thus, the roots are x = ------------------

                                               2

15m+9n=-6 solve for n
Yanka [14]

Answer:

( - 2 - 5m ) / 3

Step-by-step explanation:

15m + 9n = - 6

9n = - 6 - 15m

Divide by 3 on both sides,

9n / 3 = - 6 / 3 - 15m / 3

3n = - 2 - 5m

n = ( - 2 - 5m ) / 3
