What is the solution to this equation? 3[x] - 1 = 8

Mathematics
1 answer:
Yanka [14]3 years ago
8 0

Answer:

3

Step-by-step explanation:

The whole goal is to isolate the variable.

3x-1=8

1+3x-1=8+1 first add 1 to both sides of the equation to cancel out the -1

3x=9 now just divide 3 to both sides of the equation because the opposite of multiplication is division. So dividing 3 on both sides cancels out the 3 to isolate the x

3x/3=9/3

x=3

Using it's concept, the range of the function is given by:

y ≥ 1

<h3>What is the range of a function?</h3>


The range of a function is composed by the set that contains all output values for the function. Considering the graph of the function, the range is given by all the values of y, which compose the vertical axis of the graph.

Looking at this graph, the function assumes values of 1 and greater, hence the range of the function is given by:

y ≥ 1.

Answer:

a = 370,000

b = 2,115,000

c = 4,230,000

city c is 11.4 times the population of city a

Step-by-step explanation:

10 to the 5 degree is 100,000. multiply that by 3.7 to get the population of City a.

City C is 2,115,000 * 2.

divide the population of City C by the population of City a.

4,230,000 ÷ 370,000= 11.43

PLEASE HELP,, MARKING BRAINLIEST!!!<br><br> Solve for the value of x.
iris [78.8K]

Answer:

\huge\boxed{\sf x = 37}

Step-by-step explanation:

We know that,

The sum of interior angles of a triangle is 180 degrees.

So,

2x + 4 + 2x - 9 + x = 180

5x - 5 = 180

Add 5 to both sides

5x = 180 + 5

5x = 185

Divide both sides by 5

x = 185 / 5

x = 37

\rule[225]{225}{2}

Hope this helped!
