(1)4x + 3> 15 or -6x>=12

4x+3>15, subtract 3 on both sides (4x> 12) and then divide both sides by 4

x > 3

-6x>=12, divide both sides by -6 , so x<=-2

x>3 or x<=-2

The middle graph satisfies the above inequality

(2) -8x>-24 and -10<=2x-6

-8x>-24 , divide both sides by -8 , so it becomes x < 3

-10<=2x-6, add both sides by 6 , -4<=2x . then divide both sides by 2

x >=-2

x>-2 and x<3

The last graph satisfies the above inequality

-29<=9x-2<16

Add both sides by 2 and then divide both sides by 9

-27 <= 9x < 18

divide both sides by 9

-3 <= x < 2

x lies between -3 and 2

The first graph satisfies the above inequality

Please give me the answer quick

Answer:

MON= 57

Step-by-step explanation:

5x-23+3x-15=90

8x-38=90

8x=128

x=16

PLUG 16 INTO MON EQUATION

5(16)-23=57

therefore,

MON=57

USE COMPLEMENTARY FOR PROBLEMS LIKE THIS :)))

(btw, assuming that the angle is 90 degrees)

Mario says that the expression 4+3n² has four terms: 4, 3, n, and 2. Is he correct? explain.

stich3 [128]

Mario says that the expression $4+3n^2$ has four terms: 4, 3, n, and 2. Mario is incorrect

<em><u>Solution:</u></em>

Given that the expression is:

$4+3n^2$

Given that, Mario says that the above expression has four terms

But Mraio is incorrect

Because the given expression has two terms only

4 is one of the term

$3n^2$ is another term

So there are totally 2 terms only

A term can be a signed number, a variable, or a constant multiplied by a variable or variables

Here 3 is a constant multiplied by $n^2$

So, $3n^2$ is one term

Each term in an algebraic expression is separated by a + sign or - sign

Thus there are two terms in mario expression
