You joined an online coupon club. You earned 100 bonus points just by signing up.
Mkey [24]

Answer:

y = 10x + 100

Step-by-step explanation:

The 100 bonus points are guaranteed, no matter if you use the site for 0 months or more. Thus, 100 is the constant, the y-intercept in a graph.

The 10 points you earn for each month is the rate of change, or slope.

The equation is:

y = 10x + 100

where x represents the number of months used, and y is the total points.

As a function, the equation is:

p(x) = 10x + 100

where x is the number of months, and p meaning points.

Solve the formula x-2y=15 for y
umka2103 [35]

Answer:

y = (1/2)x - (15/2)

Step-by-step explanation:

goal: to rearrange the expression such that it is in the form

y = f(x); where f(x) is an expression in terms of x

given:

x - 2y = 15      (subtract x from both sides)

-2y = 15 - x    (multiply both sides by -1 to make left side positive)

2y = -15 + x   (divide both sides by 2 and rearrange)

y = (1/2)x - (15/2)
