<span>If a and h are real numbers, find the following values for the given function.
f(x) = 7 − 3x
(a) 
f(a) = 7-3a
------------------------
(b) 
f(−a) = 7-3(-a) = 7+3a
------------------------
(c) 
−f(a) = -(7-3a) = 3a-7
------------------------
(d) 

f(a + h) = 7 -3(a+h) = 7-3a-3h
------------------------
(e) 
f(a) + f(h) = (7-3a)+(7-3h) = 14-3a-3h
------------------------
(f)
if h ≠ 0,

[f(a + h) − f(a)]/h = {[7-3a-3h]-[7-3a]}/h = [-3h]/h = -</span></span>

x = number of packages he bought

y = number of popsicles in each package

Here are the two equations:

xy = 54

x = 3 + y

Using the substitution method, you can solve them to find x and y.

(3 + y)y = 54,

3y + y^2 = 54

y^2 + 3y - 54 = 0

Solve the quadriatic equation:

(y +9)(y - 6) = 0

y = -9, 6.

Plug y into: xy = 54

x(-9) = 54, x = -6.

x(6) = 54, x = 9.

So he bought 9 packages of popsicles, bc you can't bye -6 packages.
