The points (3,-2) and (2, 1) are both solutions to which inequality?
KIM [24]

(3, -2) and (2, 1) are solutions to the inequality y <= 3/2x - 1

<h3>How to determine the inequality?</h3>

The complete question is added as an attachment

The points are given as:

(3, -2) and (2, 1)

Next, we test the points on each inequality in the list of options.

So, we have:

<u>Option 1</u>

y > 1/2x + 2

Substitute (3, -2) and (2, 1) for x and y

-2 > 1/2 * 3 + 2 ⇒ -2 > 3.5 -- false

2 > 1/2 * 1 + 2 ⇒ 2 > 2.5 -- false

Hence, (3, -2) and (2, 1) are not solutions to the inequality y > 1/2x + 2

<u>Option 2</u>

y <= 3/2x - 1

Substitute (3, -2) and (2, 1) for x and y

-2 <= 3/2 * 3 - 1 ⇒ -2 <= 3.5 -- true

1 <= 3/2 * 2 - 1 ⇒ 1 < 2 -- true

Hence, (3, -2) and (2, 1) are solutions to the inequality y <= 3/2x - 1

<u>Option 3</u>

y >= 4x - 2

Substitute (3, -2) and (2, 1) for x and y

-2 >= 4 * 3 - 2 ⇒ -2 >= 10 -- false

2 <= 4 * 2 - 2 ⇒ 2 <= 6 -- false

Hence, (3, -2) and (2, 1) are not solutions to the inequality y >= 4x - 2

<u>Option 4</u>

y < -2x + 1

Substitute (3, -2) and (2, 1) for x and y

-2 < -2 * 3 + 1 ⇒ -2 < -5 -- false

2 < -2 * 2 + 1 ⇒ 2 < -3 -- false

Hence, (3, -2) and (2, 1) are not solutions to the inequality y < -2x + 1

If {a_{n}} and {b_{n}} are geometric sequences with common ratios of r₁ and r₂, is {a_{n}b_{n}} a geometric sequence too? If yes
MissTica
A_{n+1}b_{n+1} / a_{n}b_{n} =( a_{n+1} /  a_{n}) * (  b_{n+1} /  b_{n} ) = ( r1 ) * ( r2) =>
{a_{n}b_{n}} a geometric sequence;  the common ratio is  ( r1 ) * ( r2) .

Please help me with this
Harrizon [31]

Answer:

B, D

Step-by-step explanation:

Angles 1 and 2 combined form a right angle, so the sum of their measures is 90°.  Therefore, they are complementary angles.

Since they share a common side and vertex and don't overlap, they are also adjacent angles.
