Your solution would be x<25
The value of x when y = 2 is x = 36
Step-by-step explanation:
The equation that we have in this problem is:

In order to find the value of x when y is equal to
y = 2
We need to re-arrange the equation making x the subject.
We proceed as follows:
1) We add +7 on both sides:

2) Now we multiply both sides by 4:

3) Now we can substitute y = 2 and find the value of x:

volume of a rectangular prism = whl
w= 7 1/2
h = 2 1/2
l = 3 1/2
w x h x l
A stuntman jumping off a 20-m-high building is modeled by the equation h = 20 – 5t2, where t is the time in seconds. A high-speed camera is ready to film him between 15 m and 10 m above the ground. For which interval of time should the camera film him?
Answer:

Step-by-step explanation:
Given:
A stuntman jumping off a 20-m-high building is modeled by the equation
-----------(1)
A high-speed camera is ready to making film between 15 m and 10 m above the ground
when the stuntman is 15m above the ground.
height
Put height value in equation 1





We know that the time is always positive, therefore 
when the stuntman is 10m above the ground.
height
Put height value in equation 1







Therefore ,time interval of camera film him is
