Solve this equation(15x^3- 2)^3= 2197

Mathematics
1 answer:
aliya0001 [1]3 years ago
5 0

Answer:

x=1

Step-by-step explanation:

(15x^3- 2)^3= 2197

Take the cube root of each side

(15x^3- 2)^3 ^ 1/3= 2197^ 1/3

15x -2 = 13

Add 2 to each side

15x^3- 2+2= 13+2

15x^3 =15

Divide each side by 15

15x^3 /15 =15/15

x^3 =1

Take the cube root of each side

x^3 ^1/3 = 1^1/3

x=1

Twice the product of 3and a number exceeds the sum of the number and 80 by 10.what is the number?
Hatshy [7]
First, create an equation with the criteria given.

If we let x be your number,
2(3x) = 80 + x + 10
(2(3x) is twice the product of 3 and x, and if it exceeds x+80 by 10, then we add 10 to x+80 to make the two sides of the equation equal.)

Now, solve for x.

6x=90+x \\ 5x=90 \\ x=18

Solve the following equation: <br>(n + 1) + 3(n - 1) = 2(n - 1)(n + 1)​
Mnenie [13.5K]

Answer:

n = 0, n =2

Step-by-step explanation:

Given

(n + 1) + 3(n - 1) = 2(n - 1)(n + 1) ← distribute parenthesis on both sides

n + 1 + 3n - 3 = 2(n² - 1), that is

4n - 2 = 2n² - 2 ( subtract 4n - 2 from both sides )

0 = 2n² - 4n ← factor out 2n from each term )

0 = 2n(n - 2)

Equate each factor to zero and solve for n

2n = 0 ⇒ n = 0

n - 2 = 0 ⇒ n = 2

How to graph this! Thank you
matrenka [14]

Answer:

Step-by-step explanation:

Yay graphs!!!!!!

Okay so as you should know, the structure of a linear equation is y = mx + b.

B is the y-intercept

so the first thing to do is mark the coordinates (0,1) as the y-intercept

Now the slope is 1/4 x

this is also known as rise/run

A simpler way to do that is from (0,1) move up 1 and over four and place a point there

The coordinate should be (4,1)

Then draw a line through the two points
