3) Solve the System of Equations using Elimination/Combinations. (5 points)
Schach [20]

Answer:

(1, 2 )

Step-by-step explanation:

Given the 2 equations

- 2x - y = - 4 → (1)

x + 2y = 5 → (2)

Multiplying (2) by 2 and adding result to (1) will eliminate x- term

2x + 4y = 10 → (3)

Add (1) and (3) term by term to eliminate x

0 + 3y = 6

3y = 6 ( divide both sides by 3 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (2)

x + 2(2) = 5

x + 4 = 5 ( subtract 4 from both sides )

x = 1

solution is (1, 2 )

Is this answer right?
Dmitrij [34]

Answer:

  Blank 1: 64° (or 32°, depending on what the label applies to)

  Blank 2: 42

Step-by-step explanation:

It is a common mistake to believe you have solved the problem when you have found the value of the variable(s) in the problem. You have correctly found the values of n (42) and m (9). However, that is not what the problem is asking for.

We cannot tell if the value (1/2n+11)° is referring to angle DAB, or to angle CAB. In any event, (1/2n+11)° = (1/2×42 +11)° = 32°.

If that is angle CAB, then angle DAB is twice that value, 64°.

If that is angle DAB, then angle DAB is 32°.

__

The side length CD is the same as any other side length in a rhombus, so ...

  CD = 4m+6 = 4×9 +6

  CD = 42 . . . . units

A square is inscribed in a circle. If the area of the square is 9 in2, what is the ratio of the radius of the circle to the side
vlada-n [284]

Regardless of the size of the square, half the diagonal is (√2)/2 times the side of the square.

The ratio is (√2)/2.

_____

Consider a square of side length 1. The Pythagorean theorem tells you the diagonal measure (d) is ...

... d² = 1² +1² = 2

... d = √2

The distance from the center of the square to one of its corners (on the circumscribing circle) is then d/2 = (√2)/2. This is the radius of the circle in which our unit square is inscribed.

Since we're only interested in the ratio of the radius to the side length, using a side length of 1 gets us to that ratio directly.
