23b^4+(-10b^4)
23b^4-10b^4)
13b^4
Answer:
Step-by-step explanation:
When the interest compounds continuously, our formula is
If we start with 10000 and are looking for how long, t, it takes to double, we are looking for how long it will take for our account to have 2 times 10000. That's 20000. Therefore, our equation is
Divide both sides by 10000 to get
Take the natural log of both sides to "undo" that e:
Again, since ln and e undo each other what we have now is
ln(2) = .11t and
so
t = 6.3 years
Hey there!
In order to solve this equation for y, you need to use addition, subtraction, and division to combine and simplify the terms. You do this by first eliminating the terms, which you do by completing whatever will make each term equal to zero. Then, you'll repeat this same thing on the other side of the equation, like so:
<span>5y + 3 = 2y – 3x + 5
– 3 – 3
</span>
5y = 2y – 3x + 2
As you can see, I subtracted three from +3 the left side to cancel it out, then repeated that on the right side to the similar term (the constant). Now, just repeat that with your other terms until your equation is equal to y.
5y = 2y – 3x + 2
+ 2y + 2y
<u>7y</u> = <u>–3x + 2</u>
7 7
y = <u>–3x + 2</u>
7
When you can't simplify any more, you have your answer. y will be equal to –3x + 2 over 7.
Hope this helped you out! :-)
Answer:
John paid $72
Step-by-step explanation:
To find the discount, we take the regular price and multiply it by the discount percentage
Discount = 90 * .2
= $18
The new price is the regular price minus the discount
New price = 90 -18
= $72
Answer:
beens they are 2 completely different things you would take and divide 9 by 3 to get 3 but you would not switch the sign because you are not dividing by a negative so the answer would be x < 3
