This is additive because it doesn’t pass through the origin. It’s a line in the form y = mx + b

Remember that additive equations are in the form y = a + b, mx simply becomes one term when you multiply it.

What are the next three numbers in this pattern? 729, 243, 81, 27, __, __, __

frez [133]

Divide by 3 each time

so

#1 is 9, because 27/3 = 9
#2 is 3, because 9/3 = 3
#3 is 1, because 3/3 = 1

So your answer is 9, 3, 1

hope this helps

X y

Darina [25.2K]

Answer:

Part 1) The rate of change is $\frac{17}{15}$

Part 2) The initial value is 68

Part 3) The function rule to the linear model is $y=\frac{17}{15}x+68$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

step 1

Find the slope

take two points from the table

(0,68) and (15,85)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{85-68}{15-0}$

$m=\frac{17}{15}$

In a linear function , the slope is the same that the rate of change

therefore

The rate of change is $\frac{17}{15}$

step 2

Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

Looking at the table

For x=0, y=68

therefore

The y-intercept is

$b=68$

The y-intercept is also called the initial value

therefore

The initial value is 68

step 3

Determine the function rule to the linear model

$y=mx+b$

we have

$m=\frac{17}{15}$

$b=68$

substitute

$y=\frac{17}{15}x+68$

Answer:

Step-by-step explanation:

hello :

x3^-8=0 means : x3^=8

but : 8 = 2^3

so : x3^= 2^3
