The equation starts as

in order to solve for k first you must multiply each side by p. you must multiply each side by p as it is originally being divided, to get rid of it you must do the opposite operation.

you cross multiply and end up with

now to leave k by itself you must divide by t

the t cancels out or becomes 1 leaving you with the answer of
Answer:
f(-7)= 58
Step-by-step explanation:
plug in -7 for x
f(-7)=6(-7)+100
f(-7)=-42 plus 1000
=58
12 and 1/8, I just simplified 2/16 to 1/8
Coefficients are numbers that are next to variables, multiplying them, therefore changing the value. The first 3 and 5 were next to the variables, so they are coefficients.
