Whats the original slope of y-7/12=5/8(x+9)

m = 5/8

Step-by-step explanation:

y-7/12=5/8(x+9) represents a linear equation whose slope we want to determine.

Clear this y-7/12=5/8(x+9) of fractions by finding the LCD (it is 72) and multiplying each term by it:

72[y - 7/12 = (5/8)(x+9)

We obtain 72y - 42 = 45(x+9).

Perform the indicated mult.:  72y - 42 = 45x + 405.

Solving for y, we get 72y = 45x + 405 + 42, or 72y = 45x + 447.

Dividing boh sides by 72 to isolate y, we get y = (45/72)x + 447/72.

The slope of this straight line is 45/72, which can be reduced to m = 5/8.

the answer is d

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
