Answer:

x = 5

Step-by-step explanation:

Given

6 = 3x - 9 ( add 9 to both sides )

15 = 3x ( divide both sides by 3 )

5 = x

Answer:

x = 5

Step-by-step explanation:

6 = 3x - 9

If you add 9 to both sides 6 + 9 = 3x - 9 + 9. You would get the equation 15 = 3x because adding 9 to both sides cancels out the 9 on the right side of the equation. Then you would divide by 3 on both sides 15/3 = 3x/3 which would give you 5 = x your answer

Option 1: y = 5x+5 is the correct answer

Step-by-step explanation:

We can put the values of x in each option one by one and then compare the output to find the best option

So,

<u>For y = 5x+5:</u>

Putting x=1,2,3,4,5...

y = 5(0)+5 = 0+5 = 5\\y = 5(1) +5 = 5+5 = 10\\y = 5(2) + 5 = 10+5 = 15\\y = 5(3) + 5 = 15+5 = 20

The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5

Hence,

Option 1: y = 5x+5 is the correct answer

Please help guys!!!!!!!!!!!!!!
hram777 [196]

Answer:

a) x = -10

b) x = 7

Step-by-step explanation:

a)

2(x + 3) = x - 4

2x + 6 = x - 4

2x - x = -4 - 6

x = -10

b)

4(5x - 2) = 2(9x + 3)

20x - 8 = 18x + 6

20x - 18x = 6 + 8

2x = 14

x = 7

In this assignment, you will explore how the volume is changed when you adjust the height or radius of a cylinder. You will drag
lesantik [10]

The volume of a cylinder changes when you adjust the height or radius as the volume either increases or reduces.

<h3>How to illustrate the volume?</h3>

Let's assume that the height and radius are 14cm and 7cm. The volume will be:

= πr²h

= 3.14 × 7² × 14

= 2154.04cm³

When the radius and height are reduced to 5cm and 9cm, the volume will be:

= πr²h

= 3.14 × 5² × 9

= 706.5cm³

This illustrates that the volume reduces when the height and radius reduces.
