Three-dimensional, or perspective view
Do distance divided by time to get the speed.
200 / 2.5 = 80.
The speed is 80 miles per hour(mph).
Hope this helps :)
Hypotenuse therom ( a^2 + b^2 = c^2)
1) find c^2
22^2 + 16.1^2= c^2 ———->743.21
2) square root c^2 to find c
square root of 743.21 = 27.2 so D
Answer:
The values of x and y to the given equation are x=3 and y=-1
The solution to the given equation is (3,-1)
Step-by-step explanation:
Given equations are 

To solve given equations by using elimination method :
Mutliply the equation (2) into 2 we get

Now adding the equations (1) and (3)


_______________


Therefore y=-1
Now substitute the value of y=-1 in the equation (1) we get
-2x+3(-1)=-9
-2x-3=-9
-2x=-9+3

Therefore x=3
The values of x and y to the given equation are x=3 and y=-1
The solution to the given equation is (3,-1)
Answer:
, D
Step-by-step explanation:
3 if x is greater than or equal to 1 is nothing. That leaves us with
if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is
, which is D.
