Answer: b. 160
Step-by-step explanation: just took the test
Answer:
Part 1) The y-intercept is the point ![(0,-3)](https://tex.z-dn.net/?f=%280%2C-3%29)
Part 2) The x-intercepts are the points ![(-\sqrt{3},0)\ and\ (\sqrt{3},0)](https://tex.z-dn.net/?f=%28-%5Csqrt%7B3%7D%2C0%29%5C%20and%5C%20%28%5Csqrt%7B3%7D%2C0%29)
Step-by-step explanation:
we have
![y=x^{2}-3](https://tex.z-dn.net/?f=y%3Dx%5E%7B2%7D-3)
This is a vertical parabola open upward
step 1
Find the y-intercept
we know that
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0
![y=(0)^{2}-3](https://tex.z-dn.net/?f=y%3D%280%29%5E%7B2%7D-3)
![y=-3](https://tex.z-dn.net/?f=y%3D-3)
The y-intercept is the point (0,-3)
step 2
Find the x-intercepts
we know that
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0
![x^{2}-3=0](https://tex.z-dn.net/?f=x%5E%7B2%7D-3%3D0)
solve for x
Adds 3 both sides
![x^{2}-3+3=0+3](https://tex.z-dn.net/?f=x%5E%7B2%7D-3%2B3%3D0%2B3)
![x^{2}=3](https://tex.z-dn.net/?f=x%5E%7B2%7D%3D3)
take square root both sides
![x=(+/-)\sqrt{3}](https://tex.z-dn.net/?f=x%3D%28%2B%2F-%29%5Csqrt%7B3%7D)
so
The x-intercepts are the points ![(-\sqrt{3},0)\ and\ (\sqrt{3},0)](https://tex.z-dn.net/?f=%28-%5Csqrt%7B3%7D%2C0%29%5C%20and%5C%20%28%5Csqrt%7B3%7D%2C0%29)
Answer:
12
Step-by-step explanation:
the original ratio was 3/5 , so apply that to 20 and 3/5 of 20 is 12
Answer: 120:72
Step-by-step explanation:
tulips: 72/3 = 24
so multiply roses to get an equal ratio, 24 x 5 = 120
