The y-coordinate is ​ −1−1 ​, the x-coordinate is ​ −2−2 ​, and the point lies in the third quadrant.

The y-coordinate is ​ −1−1 ​, the x-coordinate is ​ −2−2 ​, and the point lies in the fourth quadrant.

The x-coordinate is −1−1 , the y-coordinate is −2−2 , and the point lies in the fourth quadrant.

Answers

Answer:

The statement is true about the point (-1,-2) is the x-coordinate is ​−1 ​, the y-coordinate is ​−2 ​, and the point lies in the third quadrant.

Step-by-step explanation:

As the point given be (-1,-2) .

As the points always in the form (x,y) .

Thus in points (-1,-2) x-coordinate is -1 and y- coordinate is -2 .

As shown in the graph below the point (-1,-2) is lies in the third quardant .


The x-coordinate is ​ −1−1 ​, the y-coordinate is ​ −2−2 ​, and the point lies in the third quadrant.

Simplify and solve this equation: 4m + 9 + 5m – 12 = 42.A. m = -4
B. m = 4
C. m = –5
D. m = 5

Answers

4m + 9 + 5m – 12 = 42
Given the equation combine all similar terms found on a side of the equation.
You can add the "m" and get: 9m + 9 – 12 = 42
You can combine the 9 and the -12 and get: 9m - 3 = 42
Toget the "m" alone add or subtract any number necessary from the leftside so the number is 0, and do the same to the right: 9m - 3 + 3 = 42 +3, leaving you: 9m = 45
Divide each side by the number of "m" you have: (9m)/9 = 45/9 which simplifies to m=5.

The solution of expression 4m + 9 + 5m - 12 = 42 by combining like terms is,

⇒ m = 5

Given that,

A mathematical expression is,

⇒ 4m + 9 + 5m - 12 = 42

Now, simplify the expression by combining like terms and solve for m as,

⇒ 4m + 9 + 5m - 12 = 42

Combine like terms,

⇒ 9m - 3 = 42

Add 3 on both sides,

⇒ 9m = 42 + 3

⇒ 9m = 45

Divide by 9 on both sides,

⇒ m = 45/9

⇒ m = 5

So, the solution is,

⇒ m = 5

According to the Fundamental Theorem of Algebra, how many roots exist for the polynomial function? f(x) = (x3 – 3x + 1)2 2 roots 3 roots 6 roots 9 roots

Answers

According to the Fundamental Theorem of Algebra, 6 roots exist for the polynomial function.

What is the fundamental Theorem of Algebra?

Fundamental Theorem of Algebra states that every polynomial equation of degree n with complex number coefficients has n roots, or solutions, in the complex numbers. The roots can have a multiplicity greater than zero.

Given polynomial function

f(x)=(x^(3)-3x+1 )^(2)

It has (x^(3) )^(2) term in the given polynomial

The fundamental theorem of algebra guarantees that a polynomial equation has the same number of roots as its degree.

= 3 × 2

= 6

So, 6 roots exist for the polynomial function.
