Solving for X:
1) y=-8x+6.5 y=-4x+11
2) -8x+6.5=-4x+11
3) -8x=-4x+11-6.5 (Subtract 6.5 from both sides)
4) -8x+4x=11-6.5 (Add 4x to both sides)
5)-4x=4.5
5)x=-1.125
Solving for Y:
y=-8(-1.125)+6.5
y=9+6.5
y=15.5
y=-4(-1.125)+11
y=4.5+11
y=15.5
x=-1.125
y=15.5
or
(-1.125,15.5)
The decimal number, 0.000000000001, written as a power of 10 is expressed as: 1.0 × 10^(-11).
<h3>How to Write a Decimal Number as a Power of 10?</h3>
To express a decimal number as a power of 10, we have to take into consideration, how many decimal places do we have in the decimal number. This will determine what power of 10 the base number would be raised to.
Given the decimal number as, 0.000000000001, the number of decimal places we have in the decimal number is 11. So, we would move the decimal point to 11 places to the right, then multiplied by 10 raised to the power of minus 11.
That is, 1.0 × 10^(-11). Therefore, the decimal number, 0.000000000001, written as a power of 10 is expressed as: 1.0 × 10^(-11).
