Answer:

Four consecutive numbers are 2, 6, 10 and 14

Step-by-step explanation:

15(a² - 9d²) = 7(a² - d²)

15a² - 135d² = 7a² - 7d²

15a² - 7a² = 135d² - 7d² 

8a² = 128d²

Putting the value of a = 8 in above we get.

8(8)² = 128d²

128d² = 512

d² = 512/128

d² = 4

d = 2

So, the four consecutive numbers are

8 - (3*2)

8 - 6 = 2

8 - 2 = 6

8 + 2 = 10

8 + (3*2)

8 + 6 = 14

Can x=9.4 be written in y=mx+b form?
Westkost [7]

Answer:

The given equation cannot be written in slope intercept form

Step-by-step explanation:

we know that

y=mx+b

Is the equation of the line in slope intercept form

where

m is the slope

b is the y-intercept

In this problem we have

x=9.4

This is a vertical line (parallel to the y-axis)

The slope is undefined

therefore

The given equation cannot be written in slope intercept form

How many pieces of gum are in 4 packages of gum?"

Using a proportional function, there are 60 pieces of gum in 4 packages.

<h3>What is a proportional relationship?</h3>

Two values x  and  y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.

The constant k is called constant of proportionality.

The constant is given by:

k = 15/1

k = 30/2

k  = 45/3

k  = 15.

Therefore, the number of pieces of gums in x packages is given by:

y = 15x.

In 4 packages:

y = 15 x 4

y = 60 pieces of gum.

Using a proportional function, there are 60 pieces of gum in 4 packages.
