Answer:
Hence, 12,90,000 can be expressed as
.
Step-by-step explanation:
- Given 12,90,000
- Use given, move the decimal point so that first factor is greater than or equal to 1 but less than 10 .
- Then count n and write in scientific notation.
Step 1 of 1
Consider 12,90,000
1.29
So, 1.29 lies between 1 & 10.
Now, Decimal moved to 6 places at left.

So,
.
Finding the x-intercept first:
5 (x - 2) = y - 3
5x - 10 = 0 - 3
5x - 10 = -3
5x = 7
x = 7/5 or 1.4
Solve for y
y - 3 = 5 (0 - 2)
y - 3 = 0 - 10
y - 3 = -10
y = - 7
