Answer:
x=-1
Step-by-step explanation:
3x+12-8x=19+2x (combine liked terms)
-5x+12+19=2x (move variable to the left-hand side and change its sign)
-5x-2x+12=19 (combine liked terms)
-7x=19-12 (divide both sides of the equation by -7)
x=-1
Answer:
A. y - 4 = 3(x + 2)
Step-by-step explanation:
Point slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line
Plug in the slope and given point:
y - y1 = m(x - x1)
y - 4 = 3(x + 2) is the equation
So, A is the correct answer.
Answer:
$220.18
Step-by-step explanation:
The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:
![A(n)=P \left(1+\dfrac{r}{k}\right)^{nk}](https://tex.z-dn.net/?f=A%28n%29%3DP%20%5Cleft%281%2B%5Cdfrac%7Br%7D%7Bk%7D%5Cright%29%5E%7Bnk%7D)
In Jayden's case:
- A(n)=$400
- r=12%=0.12
- n=5 years
- k=12 Months
We want to determine the amount Jayden put in the savings account.
![400=P \left(1+\dfrac{0.12}{12}\right)^{12*5}\\400=P \left(1+0.01}\right)^{60}\\400=P \left(1.01}\right)^{60}\\P=\dfrac{400}{\left(1.01}\right)^{60}}\\](https://tex.z-dn.net/?f=400%3DP%20%5Cleft%281%2B%5Cdfrac%7B0.12%7D%7B12%7D%5Cright%29%5E%7B12%2A5%7D%5C%5C400%3DP%20%5Cleft%281%2B0.01%7D%5Cright%29%5E%7B60%7D%5C%5C400%3DP%20%5Cleft%281.01%7D%5Cright%29%5E%7B60%7D%5C%5CP%3D%5Cdfrac%7B400%7D%7B%5Cleft%281.01%7D%5Cright%29%5E%7B60%7D%7D%5C%5C)
![P=\$220.18](https://tex.z-dn.net/?f=P%3D%5C%24220.18)
Jayden earned $220.18 from doing odd jobs.
