Answer:

4.21×10^10

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps :)

Dale currently has $599 in his savings account. Prior to getting paid, he had $230 in his savings account. How much was Dale’s p
nlexa [21]
Hi!

So really focus on the fact that he started at $230, and then added an amount of money which we'll call x, which made his total equal $599. 

Take the parts I put in bold, and write the equation.
$230 + x = $599

Now we need to find x. 

Whatever we do to the equation, we do it to both sides. 
Our goal is to isolate x on one side. 

Subtract 230 from both sides. 
$230 - $230 + x = $599 - $230
x = $369

The answer is A. $230 + x = $599 x = $369

Hope this helps! :)

state whether the lines represented by the equations y=1/2x-1 and y+4=-1/2(x-2) are parallel, perpendicular, or neither.
Zepler [3.9K]
Parallel because they have the same slope. Y+4= -1/2(x-2) is in point slope form, simplified to y intercept form is y=1/2-5... The slope (m) in both equations is the same, if you graphed the equations they would be parallel
