Answer:

The answer is an= 2/3 * 9^n-1

or D

Step-by-step explanation:

The explicit rule is an=a1 * r^n-1

the question tells us that a1 is 2/3, so we plug that into the rule

the question uses the recursive rule ( an=r * an-1) to tell us what r is

r= 9 and a1= 2/3

now lets plug it into our rule

an= 2/3 * 9^n-1

Correct Work

4x+8 +3(x-4)

4x +8 + 3x-12

4x+3x+8 -12

7x -4

Mistake Made

3 wasn't multiplied by the 4 in the bracket
Like terms wasn't combined in the working out
The answer was supposed to be -4, 8-4= -4

WRITE THE EQUATION OF THE LINE IN SLOPE INTERCEPT FORM.

nika2105 [10]

Answer:

the first answer ( I think these are 3 different questions) is y = -4x + 7

the second answer is y = -3x + 5

the third answer is y = 6x - 5, because the lines are parallel, they have the same slope and the y int is -5 from the point given.

Stan lawn mower had 1/8 of a gallon of gasoline in the tank. Stan started mowing and used all of the gasoline. He put 6/10 of a

tigry1 [53]

Answer: Stan used $\frac{1}{24}\ gallon$ of gasoline.

Step-by-step explanation:

Given: The amount of gasoline in the tank of Stan lawn mower= $\frac{1}{8}\ of\ gallon$

Then he put the amount of gasoline in the tank= $\frac{1}{6}\ of\ gallon$

The total amount of gasoline filled in the tank = $\frac{1}{8}+\frac{1}{6}\ gallons$

⇒ The total amount of gasoline filled in the tank = $\frac{3+4}{24}=\frac{7}{24}\ gallons$

The amount of gasoline left in the tank after mowing= $\frac{1}{4}\ of\ gallon$

Now, the total gasoline used by Stan= $\frac{7}{24}-\frac{1}{4}=\frac{7-6}{24}=\frac{1}{24}\ gallon$
