Answer:
A: (-9,-3)(-2,-4)(-5,-8)
B: (-5,2)(-1,-3)(3,2)
C: (4,-7)(-1,-3)(4,1)
D: (-1,-11)(-2,-4)(-6,-7)
Step-by-step explanation:
So of the transformations, translations are pretty much the easiest. x-1 just means move all coordinates left 1 and y-3 means move all coordinates down 3. So for the first one the x coordinate gets 1 subtracted from it and the y value gets 3 subtracted from it.
(-8,0) => (-8-1, 0-3) = (-9,-3)
I do recommend double checking though, for practice and in case I flubbed a calculation.
Answer:
![Probability = \frac{1}{8}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B1%7D%7B8%7D)
Step-by-step explanation:
Given
Represent Boys with B and Girls with G
![P(B) = \frac{1}{2}](https://tex.z-dn.net/?f=P%28B%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
![P(G) = \frac{1}{2}](https://tex.z-dn.net/?f=P%28G%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
Required
Find the probability or having 1 boy 2 girls
Since the order is not important, the probability is calculated as follows;
![Probability = P(B) * P(G) * P(G)](https://tex.z-dn.net/?f=Probability%20%3D%20P%28B%29%20%2A%20P%28G%29%20%2A%20P%28G%29)
Substitute
for P(B) and P(G)
![Probability = \frac{1}{2} * \frac{1}{2} * \frac{1}{2}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20%5Cfrac%7B1%7D%7B2%7D)
![Probability = \frac{1 * 1 * 1}{2 * 2 *2}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B1%20%2A%201%20%2A%201%7D%7B2%20%2A%202%20%2A2%7D)
![Probability = \frac{1}{8}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B1%7D%7B8%7D)

Answer:
$8.75
Step-by-step explanation:
If you do
$3.50 x 2.5 you get
$8.75
+1800 because if you were to deposit you would be losing money kinda because its in your bank account.
Let x represent the number of minutes and y the cost. Then
y - 0.85 = (1.10 - 0.85)/(10 - 5) (x - 5)
y - 0.85 = 0.25/5 (x - 5) = 1/20 (x - 5) = 1/20 x - 1/4
y = 0.05x - 0.25 + 0.85 = 0.05x + 0.6
y = 0.05x + 0.6
The cost of 25 minutes = 0.05(25) + 0.6 = 1.25 + 0.6 = $1.85
