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.
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)
Answer: y = 
<u>Step-by-step explanation:</u>
y = ax² ; where a represents the vertical stretch
a reflection across the x-axis is represented by making the a-value negative.
Its D because if you plug in each # with x it will give you the output which is y.
