Select the ordered pairs that are solutions to the inequality 2x-3y greater than or equal to 12

Dima020 [189]

Just rank every pair of numbers for example:
The first one is: 1,-3.
2•1-3•-3>12
2+9>12
11>12
That's Incorrect. The first pair of numbers doesn't match the inequality.
Now do the same thing to all the other pairs of numbers.

Which sequence could be described by the explicit definition: t_n=2^n+1t n = 2 n + 1

yuradex [85]

Answer:

2. 27

3. Option C. 3, 5, 9, 17, 33, ...

Step-by-step explanation:

2. The sequence is defined by the explicit function $t_{n} = 2^{n} - n$

Therefore, the 5th term i.e. $t_{5}$ of the sequence.

$t_{5} = 2^{5} - 5 = 32 - 5 = 27$ (Answer)

3. The explicit definition is $t_{n} = 2^{n} + 1$

Hence, $t_{1} = 2^{1} + 1 = 3$

$t_{2} = 2^{2} + 1 = 5$

$t_{3} = 2^{3} + 1 = 9$

$t_{4} = 2^{4} + 1 = 17$

Therefore, the option C is the right sequence. (Answer)

Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of t

alex41 [277]

Answer:

$\angle MKJ = 34$

Step-by-step explanation:

Given

$\angle LKJ = 124$

Required

Find $\angle MKJ$

From the attachment:

The measure of $\angle MKJ$ is calculated using the following expression:

$\angle MKJ + \angle LKM = \angle LKJ$

Where

$\angle LKM = 90$ -- right-angled.

The expression becomes

$\angle MKJ + 90 = 124$

$\angle MKJ = 124 - 90$

$\angle MKJ = 34$

Franklin measured and labeled the angles of a triangle as shown. Jennifer says that at least one of his measures is incorrect. E

ioda

Answer:

see the explanation

Step-by-step explanation:

First way

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

In this problem

37+97+134 > 180

therefore

At least one of Franklin's measures is incorrect

Second way

we know that

A triangle can only have at most one obtuse internal angle.

In this problem the triangle has two obtuse internal angles

Remember that an obtuse angle is an angle greater than 90 degrees

therefore

At least one of Franklin's measures is incorrect
