To solve the question we need to calculate the equation of the straight line;
the equation is given by:
m=(y1-y)/(x2-x)
where;
m is the slope;
selecting 2 points from the graph say (0,2) and (2,0), the slope of the graoh will be:
m=(0-2)/(2-0)=-1
thus using point (-2,4) the equation will be given by:
-1=(y-4)/(x+2)
-1(x+2)=(y-4)
this can be written as:
-x-2=y-4
this can be written as:
y+2=-x+4
this can be written as:
y+2=-(x-2)
The answer is A.y+2=-(x-2)
Given:
Principal = Rs. 1200
Rate of interest = 25%
To find:
The time in which the interest will became equal to the principal.
Solution:
We have,
If interest is equal to the principal, then
The formula for amount is:
Substituting 
in the above formula, we get
Taking log on both sides, we get
![[\because \log a^b=b\log a]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog%20a%5Eb%3Db%5Clog%20a%5D)
Therefore, the interest will became equal to the principal in about 3.11 years.
2w - 2
w = 5
2(5) - 2
10 - 2 = 8
The value would be 8
Answer:
you need to find how many pencils the teacher needs for the class
Step-by-step explanation:
Answer:
Penelope can read 6 pages in 5 minutes.
Step-by-step explanation:
You would use the equation 1.2x = P
P=how many pages x=how many minutes
1.2(5) = 6
She can read 6 pages in 5 minutes
