5. You and a friend are each typing your research papers on computers. The function y = 1400 - 50. models the number y of words you have left to type after x minutes. For your friend, y = 1200 - 50x
models the number y of words left to type after x minutes.
(a) Graph the two equations in the same coordinate plane.
(b) What do the x-intercepts, y-intercepts, and slopes represent?

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

factor trees are nice.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

first one because it can't have a fraction in it
