C
you have the 2 side ones and the top one, you are missing the bottom vertice
Answer:
D
Step-by-step explanation:
Exponential equation takes the form
where
- a is the initial value ( a ≠ 0), and
- b is the base ( b ≠ 1)
The equation given in the problem can be written as
, so it is <em>an exponential equation, </em> where a = -4.8 and b = 4.
Thus we can say that the initial value = -4.8 and the base is 4
The correct answer is D
Answer:
B and D
Step-by-step explanation:
The probability that Andy chooses a striped shirt and a pair of blue shorts is:
![\frac{3}{4} * \frac{1}{3} = \frac{3}{12} = \frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20%2A%20%5Cfrac%7B1%7D%7B3%7D%20%3D%20%5Cfrac%7B3%7D%7B12%7D%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
The probability that Andy chooses a striped shirt and pair of tan or plaid shorts is:
![\frac{3}{4} * (\frac{1}{3} + \frac{1}{3}) = \frac{6}{12} = \frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20%2A%20%28%5Cfrac%7B1%7D%7B3%7D%20%2B%20%5Cfrac%7B1%7D%7B3%7D%29%20%3D%20%5Cfrac%7B6%7D%7B12%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
3y=x-3
y=1/3x-1
Perpendicular slope: -3
y=-3x+b
Plug in the coordinates in the equation:
-9=-3(5)+b
-9=-15+b
4=b
Equation: y=-3x+4
Also, when finding the perpendicular slope you take the reciprocal of the original slope and make it negative if it is positive and make it positive if it’s negative.
