Solve each system to find the answer

Answers

Given:

The system of equations is

[tex]5g+4k=10[/tex]

[tex]-3g-5k=7[/tex]

To find:

The solution of given system of equations.

Solution:

We have,

[tex]5g+4k=10[/tex]        ...(i)

[tex]-3g-5k=7[/tex]         ..(ii)

Multiply (i) by 5 and (ii) by 4.

[tex]25g+20k=50[/tex]        ...(iii)

[tex]-12g-20k=28[/tex]         ..(iv)

Adding (iii) and (iv), we get

[tex]25g-12g=50+28[/tex]

[tex]13g=78[/tex]

Divide both sides by 13.

[tex]g=\dfrac{78}{13}[/tex]

[tex]g=6[/tex]

Put g=6 in (i).

[tex]5(6)+4k=10[/tex]

[tex]30+4k=10[/tex]

[tex]4k=10-30[/tex]

[tex]4k=-20[/tex]

Divide both sides by 4.

[tex]k=-5[/tex]

So, the solution of the system of equation is (6,-5).

Therefore, the correct option is A.

Answers

60$

10% of 50$ is 5(50/10), so 20% (10% x 2) would be 10 (5$ x 2)

Determine whether the lines are parallel, perpendicular, or neither. 5x + 2y = 14 and y = −5x + 9

Answers

Answer: Neither

Step-by-step explanation:

5x + 2y = 14

2y = -5x + 14

y = -5/2 x + 7; slope m = -5/2

y = –5x + 9 ; slope m = -5.

Parallel lines slopes are equal and perpendicular slopes are opposite and reciprocal.

So both lines are neither parallel nor perpendicular

Answer

C. Neither.

Answer: Neither

Step-by-step explanation:

5x + 2y = 14

2y = -5x + 14

y = -5/2 x + 7; slope m = -5/2

y = –5x + 9 ; slope m = -5.

Parallel lines slopes are equal and perpendicular slopes are opposite and reciprocal.

So both lines are neither parallel nor perpendicular

Answer

C. Neither.

How is paragraph 2 structured in CGI Is the Future of Movies?Paragraph 2: When the 1993 movie Jurassic Park was released, CGI was still an unproven technology. Many people werent sure it was worth the money. But audiences were amazed by the realistic dinosaurs interacting with human actors. Jurassic Parks enormous success proved that CGI technology could look convincing and earn money. After seeing the dinosaurs, director George Lucas said, It was like one of those moments in history . . . a major gap had been crossed and things were never going to be the same. Film critic Tom Shone compared the invention of CGI to the use of sound in movies in 1927. CGI has allowed filmmakers to show Washington, DC, exploding in Independence Day, giant robots battling monsters in Pacific Rim, and an entire alien planet to come to life in Avatar. None of these effects would be convincing, or even possible, without CGI.SEE ATTACHMENT FOR MULTIPLE CHOICE!!
