Answer:

The correct option should have been $6x=6$ .

Step-by-step explanation:

Given the expression

$\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)$

solving the expression

$\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)$

Remove parentheses: (a) = a

$2x+3y+4x-3y=11-5$

Group like terms

$3y-3y+2x+4x=11-5$

Add similar elements

$6x=6$

It is clear that not a single given option is $6x=6$ . It means no option is correct. It seems you mistyped the correct options.

The correct option should have been $6x=6$ .

Find the other endpoint of the line segment with the given endpoint and midpoint: Endpoint - (1, 3) Midpoint - (0, 0)

Kobotan [32]

Answer:

The other endpoint of the line segment = (-1, -3)

Step-by-step explanation:

A segment has:

Endpoint: (1, 3)

Midpoint: (0, 0)

Let (x, y) be the other endpoint of the line segment

$\frac{\left(1\:+\:x\right)}{2}=0$

$\mathrm{Multiply\:both\:sides\:by\:}2$

$\frac{2\left(1+x\right)}{2}=0\cdot \:2$

$1+x=0$

$x=-1$

$\frac{\left(3+y\right)}{2}=0$

$\mathrm{Multiply\:both\:sides\:by\:}2$

$\frac{2\left(3+y\right)}{2}=0\cdot \:2$

$3+y=0$

$y=-3$

Therefore, the other endpoint of the line segment = (-1, -3)

The segments shown below could form a triangle.

Shalnov [3]

Answer:

Step-by-step explanation:

Condition for a triangle formed by three segments,

Sum of two segments should be greater than third segment

1). AC + BC > AB

2). AC + AB > BC

3). AB + BC > AC

1). AC + BC > AB

1 + 8 > 8

9 > 8

Triangle is possible.

2). AC + AB > BC

1 + 8 > 8

9 > 8

Triangle is possible.

3). AB + BC > AC

8 + 8 > 1

16 > 1

Triangle is possible.

Therefore, with the help of given segments triangle can be formed.

Answer is TRUE.

If f(x)=x+3 and g(x)= x^2 -4 find the expression for g(f(x))

Maksim231197 [3]

Answer:g(f(x))= x^2 +6x+5

Step-by-step explanation:

g(f(x))= x^2 -4

g(f(x))= (x+3)^2 -4

g(f(x))= (x+3)(x+3) -4

g(f(x))= x^2 +6x+9-4

g(f(x))= x^2 +6x+5
