Answer:
9x+7y+13
Step-by-step explanation:
5x+4x=9x
3y+3y+y=7y
5+8=13
It is not A or C, and D isn't specific enough (over what amount of time? is it flying up? down? It is going forward at the same height?) The most likely thing to stay consistent is the cost of fabric and it's length.
Say 1 foot of fabric is $3 (assuming there's no discount for additional feet, but math isn't that consistent with actual store sales), then 2 is $6, and 3 is $9. That is a constant rate of change.
Answer:
What the heck?
Step-by-step explanation:
The value of "x" is 
<em><u>Solution:</u></em>
Given f(x) = 4x - 6
g(x) = 8x + 4
<em><u>To find: value of x when f(x) = g(x)</u></em>
We can equate f(x) and g(x) as per given statement and solve for x
f(x) = g(x)
<em><u>Substituting the values of f(x) and g(x) in above expression,</u></em>
4x - 6 = 8x + 4
4x - 8x = 4 + 6
-4x = 10
On solving,
Thus value of "x" is
a family of functions is a set of functions whose equations have a similar form. the "parent" of the family is the equation in the family with the <u>simplest</u> form.
