Solve 2(x + 1) = 2x + 5​

Mathematics

Tomtit [17]4 years ago

Answer:

See below

Step-by-step explanation:

● 2(x+1) = 2x +5

Multiply 2 by (x+1)

● 2x + 1×2 = 2x+5

● 2x + 2 = 2x+5

Substract 2x from both sides

● 2x+2-2x = 2x+5-2x

● 2 = 5

This is impossible, so this equation has no solution.

Answer:

no solution

Step-by-step explanation:

Given

2(x + 1) = 2x + 5 ← distribute parenthesis on left side

2x + 1 = 2x + 5 ( subtract 1 from both sides )

2x = 2x + 4 ( subtract 2x from both sides )

0 = 4 ← not possible

This indicates the equation has no solution

A. Use what you've learned in this unit to model the population of Western
Leona [35]

An exponential function can either represent population growth or population decay

<h3>How to model the population</h3>

The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.

However, the following is a general guide to solve the question.

An exponential function is represented as:

y=a(1 \pm r)^x

Where:

  • (a) represent the initial value i.e. the initial population of the Western Lowland Gorillas
  • (r) represents the rate at which the population increases or decreases.
  • (x) represents the number of years since 2022
  • (y) represents the population in x years

Given that the population of the Western Lowland Gorillas decreases, then the rate of the function would be 1 -r (i.e. an exponential decay)

Take for instance:

y = 20000 * 0.98^x

By comparison.

a = 2000 and 1 - r = 0.98

The above function can be used to model the population of the Western Lowland Gorillas

A man standing on a lighthouse at a height of 124 feet sights two boats directly in front of him. One is at an angle of depressi
Ksivusya [100]

Answer:

125\ ft

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ABC find the length side BC

we know that

tan(62\°)=\frac{124}{BC}

BC=\frac{124}{tan(62\°)}

step 2

In the right triangle ABD find the length side BD

we know that

tan(33\°)=\frac{124}{BD}

BD=\frac{124}{tan(33\°)}

step 3

we know that

The distance between the two boats is the length side CD

CD=BD-BC

substitute the values  

CD=\frac{124}{tan(33\°)}-\frac{124}{tan(62\°)}=125\ ft
