Answer:
x = -2
Step-by-step explanation:
you need to use the distribution property first!
4(x + 5) = 12 ------> 4x + 20 = 12
now you need to subtract 20 from both sides so that you can isolate x
4x = -8
finally, divide -8 by four so that x is alone, meaning solve to find x!
x = -2
Hmm
that is a true statement, the product of any 2 mixed numbers between 4 and 5, will be between 16 and 25
we can show that it is true by testing the bounds
if the number is 4 and the other is 4, then it is 16
we aren't allowed to do 4 since it isn't mixed and it equals 4
that is the lower bbound
if the numbes 5 and 5 are used, then it is 25
we arene't allowed to use 5 since it isn't mixed and it equals 5
so the product of any 2 numbers between 4 and 5 will be between 16 and 25
so pick any random one
4 and 3/4 times 4 and 5/323
Answer:
[2 , ∞)
Step-by-step explanation:
y = sqrt( x-2)
The domain is the values that x can take
Since we have a square root
Domain: [2 , ∞) since the square root must be greater than or equal to zero
The range is the values that y can take
The square root starts at 0 and increases
Range [0,∞)
The inverse swaps the domain and range
Range: [2 , ∞)
Domain [0,∞)
The answer is B because area it's length times width and 5 times 3 is 15
