The answer to your question is: .75 = 3x - .03
How to solve it:
x = the cost of a pack of gum twenty years ago
.75 = 3x - .03
+ .03 + .03
.78 = 3x
/ 3 / 3
.26 = x
If a pack of gum now costs 75 cents, which is 3 cents less than three times what a pack would have cost 20 years ago, then a pack of gum would have cost 26 cents.
Answer:
f
Step-by-step explanation:
Given:
f(1) = 1 and f(-3) = 17
To find:
The lines function f.
Solution:
If f(a) = b, it means the function f passes through (a,b).
Here, f(1) = 1, it means the function f passes through (1,1).
f(-3) = 17, it means the function f passes through (-3,17).
If a linear function passes through two point
, then the equation of line is

The linear function f passes through (1,1) amd (-3,17). So, the equation of linear function is




Add 1 on both sides.


Put y=f(x), to write in function notation.

Therefore, required lines function is
.
The value of that expression is zero.
