Slope intercept form for the line with y-intercepts -1 and slope -4

baherus [9]

The slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

We know:

Slope (m) is -4

y-intercept (b) is -1

All you need to do is plug these numbers into the slope intercept formula given above!

y = -4x - 1

Answer:

$24(f(n))$

Step-by-step explanation:

$f(n+3) = 3^{n+3}\\f(n+1) = 3^{n+1}$

$f(n+3) - f(n+1) = 3^{n+3} - 3^{n+1}$

$= 27(3^n) - 3(3^n)$

$= 24(3^n)$

$= 24(f(n))$

hope this helped! :)

At a school pep rally the ratio of students who wore red to those who wore yellow is 7 to 3 their are 300 students at the rally

Serhud [2]

Red to yellow.......7:3....added = 10
so 7/10 of the total students wore red and 3/10 of the total students wore yellow

and there are 300 total students...
7/10(300) = 2100/10 = 210 wore red
3/10(300) = 900/10 = 90 wore yellow

how many more wore red.....(210 - 90) = 120 more students wore red then yellow
