Answer:

No they aren't equivalent

Step-by-step explanation:

Let's take each expression

the first one is

- (12x+24) - 9x = -12x -24 -9x = -21x -24 = -3 (7x +8)

the second expression

-6 (x+1) = -6x-6

So they aren't equivalent

Writey=1/8 x+7 in standard form using integers.
sineoko [7]

Answer:

x - 8y = - 56

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y = \frac{1}{8} x + 7

Multiply through by 8 to clear the fraction

8y = x + 56 ( subtract 8y from both sides )

0 = x - 8y + 56 ( subtract 56 from both sides )

- 56 = x - 8y, that is

x - 8y = - 56 ← in standard form

The geometric sequence graphed shows the number of mold spores in a Petri dish per day (please help!)
zavuch27 [327]

Answer:

f(1) = 2

f(n) = 2 × f(n - 1) , n ≥ 2

Step-by-step explanation:

the point of coordinates (1 , 2) is on the graph

Then

f(1) = 2

…………………………

We notice that :

f(2) = 4

f(3) = 8

f(4) = 16

16/8 = 8/4 = 4/2 = 2/1 = 2

________________________

This means the common ratio

of the geo sequence = 2

Hence ,

f(n) = 2 × f(n - 1)
