Mathematics
1 answer:
Aloiza [94]3 years ago
4 0

Answer:

x = 29

Step-by-step explanation:

c^{2} = a^{2} + b^{2}

c^{2} = 20^{2} + 21^{2}

c^{2} = 400 + 441

c^{2} = 841

\sqrt{c^2} = \sqrt{841}

c = 29

Solve the system of equations by elimination. Explain your reasoning or show your work.

Answer:

  (x, y) = (5, 4)

Step-by-step explanation:

Subtracting the second equation from the first eliminates the x term.

  (4x +6y) -(4x +2y) = (44) -(28)

  4y = 16 . . . . simplify

  y = 4

Using the second equation to find x, we have ...

  4x +2(4) = 28

  x + 2 = 7 . . . . . . divide by 4

  x = 5 . . . . . . . . . subtract 2

The solution is (x, y) = (5, 4).

Which inequality below will have a dashed boundary line with a shaded area above its graph? A. 7x − y ≤ 3 B. x − y ≤ 4 C. 2x − 9
patriot [66]
<span>Dashed boundary line means there is no equal sign in the problem. That eliminated the first two. Shaded above means it is greater than...

Now turn your inequalities into y = mx + b form
 2x - 9y > 2 --- subtract 2x from both sides
-9y > -2x + 2 -- divide by -9...and change inequality sign
y < 2/9x - 2/9 this says y is less then.....we need greater then...this is not it

try the next one...
4x + 7y > 3 --- subtract 4x from both sides
7y > 4x + 3 -- divide by 7
y > 4/7x + 3/7
this says y is greater then...this is the one we want</span>

The answer to your question is D. I hope that this is the answer that you were looking for and it has helped you.
