Answer:
-21 = 6t
Step-by-step explanation:
3t - 7 = 5t
Subtract 3t from each side
3t-7-3t = 5t-3t
-7 = 2t
Multiply each side by 3 to get 6t
-7*3 = 2t*3
-21 = 6t
The probability of Joey being first is 1/12. If that happens the probability of Chloe going next is 1/11. Then the probability of zoe being picked next would be 1/10. Then if you multiply all the fractions I gave you you would get 1/1320 which is A. So A. Is your answer!! Hope this helps you out!!
The amount of down payment Michelle paid for a dryer of $1,400 at 17% down payment is $238
Given:
Total cost of dryer = $1,400
down payment percentage = 17%
<em>Amount paid for down payment</em> = 17% of $1,400
= 17/100 × 1400
= 0.17 × 1400
= $238
Therefore, the amount of down payment Michelle paid for a dryer of $1,400 at 17% down payment is $238

Answer:
![x^2 + 4x + y^2 +8y = 0](https://tex.z-dn.net/?f=x%5E2%20%2B%204x%20%2B%20y%5E2%20%2B8y%20%20%3D%20%200)
Step-by-step explanation:
Given
![A = (-1,-2)](https://tex.z-dn.net/?f=A%20%3D%20%28-1%2C-2%29)
![B = (2,4)](https://tex.z-dn.net/?f=B%20%3D%20%282%2C4%29)
![AP:BP = 1 : 2](https://tex.z-dn.net/?f=AP%3ABP%20%3D%201%20%3A%202)
Required
The locus of P
![AP:BP = 1 : 2](https://tex.z-dn.net/?f=AP%3ABP%20%3D%201%20%3A%202)
Express as fraction
![\frac{AP}{BP} = \frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BAP%7D%7BBP%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
Cross multiply
![2AP = BP](https://tex.z-dn.net/?f=2AP%20%3D%20BP)
Calculate AP and BP using the following distance formula:
![d = \sqrt{(x - x_1)^2 + (y - y_1)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x%20-%20x_1%29%5E2%20%2B%20%28y%20-%20y_1%29%5E2%7D)
So, we have:
![2 * \sqrt{(x - -1)^2 + (y - -2)^2} = \sqrt{(x - 2)^2 + (y - 4)^2}](https://tex.z-dn.net/?f=2%20%2A%20%5Csqrt%7B%28x%20-%20-1%29%5E2%20%2B%20%28y%20-%20-2%29%5E2%7D%20%3D%20%5Csqrt%7B%28x%20-%202%29%5E2%20%2B%20%28y%20-%204%29%5E2%7D)
![2 * \sqrt{(x +1)^2 + (y +2)^2} = \sqrt{(x - 2)^2 + (y - 4)^2}](https://tex.z-dn.net/?f=2%20%2A%20%5Csqrt%7B%28x%20%2B1%29%5E2%20%2B%20%28y%20%2B2%29%5E2%7D%20%3D%20%5Csqrt%7B%28x%20-%202%29%5E2%20%2B%20%28y%20-%204%29%5E2%7D)
Take square of both sides
![4 * [(x +1)^2 + (y +2)^2] = (x - 2)^2 + (y - 4)^2](https://tex.z-dn.net/?f=4%20%2A%20%5B%28x%20%2B1%29%5E2%20%2B%20%28y%20%2B2%29%5E2%5D%20%3D%20%28x%20-%202%29%5E2%20%2B%20%28y%20-%204%29%5E2)
Evaluate all squares
![4 * [x^2 + 2x + 1 + y^2 +4y + 4] = x^2 - 4x + 4 + y^2 - 8y + 16](https://tex.z-dn.net/?f=4%20%2A%20%5Bx%5E2%20%2B%202x%20%2B%201%20%2B%20y%5E2%20%2B4y%20%2B%204%5D%20%3D%20x%5E2%20-%204x%20%2B%204%20%2B%20y%5E2%20-%208y%20%2B%2016)
