What is $1000000_{16} - 8D6A7B_{16}$ in base 16?

729585

Step-by-step explanation:

Because it's difficult to show long subtraction here, we can instead convert both numbers to base 10 first, subtract regularly, and then convert back.

Subtracting one from another, you end up with 7,509,381 in base 10, or 729585 in base 16. Hope this helps!

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
