The answer is C I believe:)
Answer:
(−5, −11), because the point satisfies both equations
Step-by-step explanation:
A solution to a system is always the ordered pair that satisfies both equations. So this explanation is the only one that would make sense.
B is the answer i I just took it
Answer:
<h3>The value of the second number is <em><u>24</u></em><em><u> </u></em>and the first no <em><u>12</u></em><em><u>.</u></em></h3>
Step-by-step explanation:
<h3> Greetings !</h3>
From, the given word explanation try to create your own equation like
- x + y = 36... (1) let the two numbers be x and y respectively.
- 2x = y ....(2) let x be the first no and it's twice that of the second number.
From, equation (1) solve for x
- x + y = 36
- x = 36-y... (3)
Substitute, equation (3) to equation (2).
- 2(36-y) =y
- 72 - 2y =y
- 72 = y + 2y.... solve for y
- 72 = 3y.... divide both sides by 3
- 72/3 = y..
- <em><u>y=24</u></em><em><u> </u></em><em><u>.</u></em>..simplified
<span>(-y+7.3)+(6.2y-9)
= 5.2 y - 1.7
so n = - 1.7</span>
