Answers

Answer 1

The factored expression of the polynomial is (x - 3)(x + 4)

How to solve the polynomial?

The polynomial expression is given as;

x^2 + x - 12

Expand the expression

x^2 + 4x - 3x - 12

Factorize the expression

x(x + 4) -3(x + 4)

Factor out x + 4

(x - 3)(x + 4)

Hence, the factored expression of the polynomial is (x - 3)(x + 4)

To keep it short, refer to triangle exterior angle theorem.

Edit: If you want the full explanation,

A isn't the answer. The triangle exterior angle states that the measure of the 2 triangle interior add up to the the exterior angle of the other interior angle within the triangle.

Meaning that

measure of angle 1 equal the measure of 3 and 4 combined.

B. is wrong they are equal to each other because angle 2 is equal to angle 2

angle 1 is equal to angle 3 and 4

So they are equal

C.Wrong unless it a 30 60 90 triangle or 45 45 90 triangle, C is wrong

D. is right since measure of angle 4 and angle 3 add up to angle 1, angle 4 would be lesser than angle 1.

Answer:

2t

Step-by-step explanation:

The expressions are not the same because different terms are negative. We can visualize the difference by rewriting the expressions as 13t + (-2t) and (-13t) + 2t. In the first expression, 13t-2t, the 2t is negative because it is being subtracted, and subtracting a number is the same as adding a negative.

The answer is 2t ^^ hope this helps

triangle A'B'C. Find the length of the line segment, AC
A. 2.23
OB. 4.47
O c. 2.44
D.2

Answers

Answer:

The distance A’C’ is 4.47 units

Step-by-step explanation:

Before we go on, we need to get the appropriate transformation

Mathematically, we have a 90 degrees clockwise rotation yielding the following;

(x,y) to (-y,x)

A is (-4,1)

C is (-2,5)

By transforming, we have

A’( -1,-4)

C’ (-5,-2)

To get the magnitude of the line segment, we are going to use the distance formula between points

We have this as;

D = √(x2-x1)^2 + (y2-y1)^2

D = √(-5-(-1))^2 + (-2-(-4))^2

D = √(-4)^2 + (2)^2

D = √(16 + 4)

D = √20

D = 4.47 units

what does this equal y=8x+1
y=6x+3

Answers

Answer:

(1,9)

Step-by-step explanation:

Step 1: Understand what the question is asking you

Assuming the question is asking you to solve for the point of interesection of the linear system

Step 2: Solve

Equate the 2 linear equations to each other and solve for'x'

8x + 1 = 6x + 3

8x - 6x = 3 - 1

2x = 2

[tex]\frac{2x}{2} =\frac{2}{2}[/tex]

x = 1

Sub x = 1 into any of the 2 equation for y

y=8(1)+1

y=8 + 1

y=9

Step 3: Therefore Statement

Therefore the answer to the linear system is (1,9)

The point of intersection for the two equations is (x=1, y=9).

To find the point where the two equations intersect, we can set them equal to each other since they both represent "y." So, we have:

8x + 1 = 6x + 3

Now, let's solve for "x":

8x - 6x = 3 - 1

2x = 2

x = 2/2

x = 1

Now that we have the value of "x," we can find the corresponding value of "y" by substituting "x = 1" into either equation. Let's use the second equation:

y = 6x + 3

y = 6(1) + 3

y = 6 + 3

y = 9

So, the point of intersection for the two equations is (x=1, y=9).
