From a graph :
the x intercept is where the line crosses the x axis. and the y intercept is where the line crosses the y axis.

from an equation :
Lets say ur equation is 2x + 5y = 10....to find the x axis, u need to sub in 0 for y and solve for x.
2x + 5(0) = 10
2x = 10
x = 5....so the x axis would be (5,0)
to find the y axis, sub in 0 for x and solve for y.
2(0) + 5y = 10
5y = 10
y = 2....so ur y intercept is (0,2)

Mold grows on bread and every day it doubles by the eighth day the entire bread is covered with mold when was half the bread cov
Brut [27]

Answer:

The mold will cover half the area as much are one day before it.

Step-by-step explanation:

Given:

Every day the mold on bread grows doubles

And by 8th day entire bread covered with it.

To Find:

When was half the bread covered by mold.

Solution:

It is said that area covered by mold doubles on each day

Total days taken to cover entire bread are 8

Let Area of bread be A

So Area covered (A) corresponds to 8 days with doubling.

So on previous day it should What ever area on 8th day/2

i.e A(8)/2

Similar on 6th day A(7)/2

So on 5ht day =A(6)/2 ,4th= A(5)/2,  on 3rd= A(4)/2, on 2nd=A(3)/2

On 1st =A(2)/2

So we required  Area= half of total.

<em>One day before the 8th day will be 7th day</em>

<em>on that day it will cover half are so that on next day will cover the double of the previous area consumed.</em>
