Now we have to,

find the required value of x.

Given that,

→ |-4x -6| = 14

Let's find the both positive value and negative value,

===================

→ -4x -6 = 14

→ -4x = 14 + 6

→ -4x = 20

→ x = 20/-4

→ [x = -5]

===================

→ -4x -6 = -14

→ -4x = -14 + 6

→ -4x = -8

→ x = -8/-4

→ x = 8/4

→ [x = 2]

===================

Therefore, x is -5 (or) 2 is the answer.

Answer:

x = -5 or x= 2

Step-by-step explanation:

|-4x-6| = 14

There are two solutions, one positive and one negative

-4x-6 = 14       -4x-6 = -14

Add 6 to each side

-4x-6+6 = 14+6       -4x-6+6 = -14+6

-4x = 20                      -4x = -8

Divide by -4

-4x/-4 = 20/-4               -4x/-4 = -8/-4

x = -5                                x = 2

A 22-ft ladder leans against a building so that the angle between the ground and the ladder is 64°. How high does the ladder rea
vodka [1.7K]

The height of the ladder on the building is 19.77 feet

<h3>How high does the ladder reach on the building?</h3>

Represent the height of the ladder on the building with h

So, the given parameters are:

Angle, x = 64 degrees

Length of ladder, l = 22 feet

The height of the ladder on the building is calculated using

sin(x) = h/l

Substitute the known values in the above equation

sin(64) = h/22

Multiply both sides by 22

h = 22 * sin(64)

Evaluate the product

h = 19.77

Hence, the height of the ladder on the building is 19.77 feet

The half-life of uranium-238 is 4.5x10^9 years. The half-life of uranium-234 is 2.5x10^5 years. How many times greater is the ha
lara31 [8.8K]

<u>Answer:</u>

Half-life of uranium-238 18 \times 10^{3} \text { times greater } that of uranium-234

<u>Explanation:</u>

Half time of uranium-238 = 4.5\times 10^9  years

Half time of Uranium-234 = 2.5\times 10^5 years

To find how much times greater the half life of uranium-238 is from uranium-234

= \frac{\text { Half life of Uranium-238 }}{\text { Half time of Uranium - 234 }}

=\frac{4.5 \times 10^{9}}{2.5 \times 10^{5}}

=18 \times 10^{3} \text { times greater }

Hence Uranium-238 is  18 \times 10^{3} \text { times greater } than Uranium-234

Iam stuck on this quiz and I need help!!
olya-2409 [2.1K]

Answer:

I think it is 3?

Step-by-step explanation:

3,  -2 ≤ 0

-5,  0 < -2 ≤ 5

3, -2 > 5

The second two lines do not hold true, as -2 is less than 0 and 5, not greater. The only that is true is the first one, but I am not sure that is how you do it.1
