vagabundo [1.1K]

GiveN:

  • ABCD is a parallelogram.
  • AC and BD are the diagonals.
  • DE = 28 units

To FinD:

  • Value of x in length of BE?

Step-wise-Step Explanation:

We know that,

In any parallelogram, the diagonals (lines linking opposite corners) bisect each other. Then, AE = EC for diagonal AC and BE = DE for diagonal BD.

⇒ BE = DE

⇒ x - 4 = 28 units

⇒ x = 32 units

Hence, The required value of x here is <u>3</u><u>2</u><u> </u><u>units</u><u>.</u>

The solutions to the inequality y &gt; −3x + 2 are shaded on the graph. Which point is a solution? (0, 2) (2, 0) (1, −2) (−2, 1)
Brilliant_brown [7]

Answer:

(2,0)

Step-by-step explanation:

The solution of the inequality y>-3x+2 is shown in attached diagram.

The boundary line is dotted line, because the sign of inequality is without notion "or equal to". The dotted line means that points lying on this line are not solutions of the inequality. The solutions are those points lying in the shaded region.

From the points (0,2), (2,0), (1,-2), (-2,1) only point (2,0) lies on the shaded region, so only point (2,0) is a solution to the inequality

An outside thermometer reads -5 degrees at 8:00 a.m. By 12:30 p.m. the temperature outside has increased by 11 degrees. At 12:30
Lesechka [4]

Answer:

73 degrees.

Step-by-step explanation:

So, let's see the information provided in the question.

At 8 AM, the thermometer was reading -5 degrees.

At 12:30 PM, the temperature has increased by 11 degrees, so it's now +6 degrees outside.

Inside Susan's house, the temperature is 7 degrees more than 11 times the outside temperature, at 12:30 PM.

So, we know the outside temperature at 12:30 PM is +6 degrees.

11 times 6 = 66 degrees.

Then we add the additional 7 degrees, to get a total of 73 degrees.
