An element with a mass of 630 grams decays by 30% per minute. To the nearest minute, how long will it be until there are 30 grams of the element remaining?

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

slope is 35 and 20 miles is the y-intercept.

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
