Answer: 9/x-1
Step-by-step explanation:
Sine you are subtracting,
x-x=o
1- -8 =9 since subtracting a negative is adding a positive.
So the answer is 9/x-1
Volume of the prism is given by:
V=(base area)*(height)
thus:
base area=1/2(a+b)*h
=1/2(1.4+0.6)*2
=2 m²
Thus the volume will be:
V=2*1
V=2 m³
Volume after 30 min:
V=2×(0.8)
V=1.6 m³
Rate of emptying the tank is:
(2-1.6)/30=1/ 75 m³/min
time taken to empty the tank:
time=volume/rate
time=2/(1/75)
=150 min
|-x + 2| = 12
|-x + 2| = 12 or |-x + 2| = -12
-x + 2 = 12 or -x + 2 = -12
- 2 - 2 - 2 -2
-x = 10 or -x = -14
-1 -1 -1 -1
x = -10 or x = 14
Solution Set: {-10, 14}
Hey there!
The range of a function consists of all the y values the function has in its graph.
Notice in the graph your y values in the function range from 3 to infinity since the graph goes on infinitely upwards and then decreases to a steady y value of 3.
Therefore, your range in interval notation would be [3,∞) since the value of three is included.
Hope this helps and have a wonderful day! :)
Answer:
Step-by-step explanation:
hello :
x²+ y² + 6x - 4y - 27 = 0 means : (x²+6x+9)-9+(y²-4y+4)-4-27 =0
(x+3)²+(y-2)² = 40....standard form when the center is (-3 , 2) and radius √40
