Henry counted units to find the distance between two points. For which pair of points could he have done this ? Select all that
Flura [38]

Options:

(–3, 5) and (–2, 5)         (–3, 5) and (–9, 3)

(5, 3) and (9, 3)             (5, –9) and (3, –5)

(2, 3) and (7, 3)

Answer:

(–3, 5) and (–2, 5)

(5, 3) and (9, 3)

(2, 3) and (7, 3)

Step-by-step explanation:

To do this, have to compare the both x and both y coordinates of the points.

If the x coordinates are equal or the y coordinates are equal, then that option is true

For (a): (-3,5) and (-2,5)

The y coordinates are the same:

i.e.

y_1 = y_2 = 5

<em>This option is true</em>

For (b): (-3, 5) and (-9, 3)

None of the coordinates are the same;

i.e.

x_1 \ne x_2

y_1 \ne y_2

<em>Hence, this option is false.</em>

For (c): (5, 3) and (9, 3)

The y coordinates are the same:

i.e.

y_1 = y_2 = 3

<em>This option is true</em>

For (d): (5, -9) and (3, -5)

None of the coordinates are the same;

i.e.

x_1 \ne x_2

y_1 \ne y_2

<em>Hence, this option is false.</em>

(2, 3) and (7, 3)

The y coordinates are the same:

i.e.

y_1 = y_2 = 3

<em>This option is true</em>

Please help i will mark brainliest for correct answers!​
Natali5045456 [20]

Answer:

9) 1/2 (or 1:2, or 50%, or .50, depending on how your teacher wants it.

10) 2/3 (or 2:3, or 66.6%, or 0.66)

Step-by-step explanation:

9) Here are the possibilities of the cards you could pick

KQ, KJ, K10, QJ, Q10, J10

Since there are 6 possibilities and only 3 of them have one face card, the probability is 3/6, or 1/2.

10) It doesn’t matter which card you pick first.  The second card has a 1 in 3 chance of being the same card (whatever it is).  That means you have a 2 in 3 chance of it NOT being the same card.  So the probability is 2/3.

0.65x = 165 000                            Divide by 0.65

0.65x/0.65 = 165000/0.65           Combine

Answer

x = 253846.15
