Today is anthony, kassim and raymond’s birthday. we want to buy a birthday candle for each one of them but we are not sure how old each one of them is turning. all we know is that as of today anthony is four years older than kasim and we know that kasim is twice as old as ramen. we also know that the sum of their ages is 64

Step-by-step explanation:

Let x be Ramen

Anthony=2x+4

Kasim=2x

Ramen=x

Therefore, if their ages add up to 64 we can add them all up

2x+4+2x+x=64

5x+4=64

5x=60

x=12

Now substitute

Ramen=12

Kasim=24

Anthony=28

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
