Cannonballs are stacked in a pyramid shape with a triangular base of 5 cannonballs on a side. How many cannonballs in all are in the stack?

one side would be 15, you need to do 15x4 to find the whole pyramid, so it would be 60

Step-by-step explanation:

(x+3)(x+7)

step-by-step explanation:

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
