Plz 1. the function b = cs gives the total number of calories in a box of food that contains s servings, and each serving contains c calories. which function can be used to determine the number of calories in a box that contains 8 servings, given the number of calories per serving? a) b(c) = 8c b) b(c) = 8 c) b(s) = 8s d) b(s) = 8 2. the function p = n(1 + r)t gives the current population of a town with a growth rate of r, t years after the population was n. which function can be used to determine the population of any town that had a population of 500 people 20 years ago, given the town’s growth rate? a) p(n) = n(1 + 20)500 b) p(n) = n(1 + 500)20 c) p(r) = 20(1 + r)500 d) p(r) = 500(1 + r)20

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
