- Vertex form: , with (h,k) as the vertex.
For this, we will be using vertex form. Firstly, plug the vertex into the vertex form equation:
Next, we need to solve for a. Plug in (-2,4) into the x and y coordinates to solve for a as such:
Putting our equation together,<u> it's </u>
<u>*Additional section*</u>
- Standard form:
Converting to standard form as such:
Answer:
5/6 minutes x 60 = 50
1/3 minutes x 60 = 20
I got my answer by multiplying by 60 since there are 60 min in one hour.
Using the keyword 'of" it means to multiply so multiply your two given numbers.
Answer:
x<u><</u>5 (x=# of shirts) or 8x <u><</u> 70-30
Step-by-step explanation:
she has $40 left for shirts, 40/8 = 5. 5 is the maximum shirts she can buy.
Answer:
angle DEC is 45 degrees
Step-by-step explanation:
angle DEC is 45 degrees because it is supplementary to 135 degrees
(with 135 degrees, adds up to 180 degrees)
There are ten numbers from 1-10
If there are ten numbers from 1-10, then there is a
of a single random number being chosen.
There are three multiples of three (including 3): 3, 6, and 9
So if there are three multiples of three, its probability is
or 3:10
The answer of choosing a multiple of three is 3:10
