Given:

The system of equation is:

-2x+4y=16

2x+2y=8

To find:

The solution of the given system of equations.

Solution:

We have,

-2x+4y=16              ...(i)

2x+2y=8                ...(ii)

Add (i) and (ii) to eliminate the variable x.

6y=24

y=\dfrac{24}{6}

y=4

Putting y=4 in (ii), we get

2x+2(4)=8

2x+8=8

2x=8-8

2x=0

Divide both sides by 2.

x=0

Therefore, the solution of given system of equations is (0,4). Hence, the correct option is A.

Which ordered pair makes both inequalities true?
kow [346]

An ordered pair which makes both inequalities true is (-1, -3).

<h3>What is an ordered pair?</h3>

An ordered pair is a pair of two points that are commonly written in a fixed order within parentheses as (x, y), which represents the x-coordinate or x-axis (abscissa) and the y-coordinate or y-axis (ordinate) on the coordinate plane of any graph.

Next, we would test the ordered pair with the given system of inequalities in order to determine which is true.

For ordered pair (-3, 5), we have:

y < –x + 1

5 < -(-3) + 1

5 < 3 + 1

5 < 4 (False).

For ordered pair (-2, 2), we have:

y < –x + 1

2 < -(-2) + 1

2 < 2 + 1

2 < 3 (True).

y > x

2 > -2 (True)

For ordered pair (-1, -3), we have:

y < –x + 1

-3 < -(-1) + 1

-3 < 1 + 1

-3 < 2 (True).

y > x

-3 > -1 (False)

For ordered pair (0, -1), we have:

y < –x + 1

-(-1) < -(0) + 1

1 < 1

1 < 1 (False).

y > x

-1 > 0 (False)

In a city the record monthly high temperature for july is 88. The record monthly low temperature is 30.
Zinaida [17]

Answer:

 58 degrees    or   [30, 88]

Step-by-step explanation:

In such a context, the word "range" can have different meanings. On the one hand it is the difference between high and low:

  88 -30 = 58 . . . . range of temperatures

__

On the other hand, it is the interval between (and including) the high and low:

  [30, 88] . . . . temperature range
