Answer:
1. If Adam burns 850 calories per hour
850×3=2550 calories for 3 hours
2. If the original price is 200$ and the discount is 30%
We get:
200 × 30
Which can be written as
200×0.3
=60
So 30% of 200 is 60
now to calculate the new price
200-60=140$
The new price is 140$
Answer:
Domain: All the real numbers
Range: All the real numbers
Step-by-step explanation:
The domain of a function is the complete set of possible values of the independent variable 'x'. That is to say, all the values that 'x' can take:
In this case, f(x)= 2x+1, the independent variable has no restrictions. Meaning that 'x' can take all the Real Values. In set notation: x∈ℝ.
The range of a function is the complete set of all possible resulting values of the dependent variable 'y'. In this case, given that the independent variable has no restrictions, the dependent variable 'y' can take any value. So, the range is: y ∈ ( −∞, ∞ ) - All the real numbers.
4y - 20.......u need to find a common factor that can go into 4y and 20.....the only common factor is 4. So u can factor that out.....4 goes into 4 one time (but do not forget the y) and 4 goes into 20 five times....4(y - 5)
4(y - 5)...u can also check ur answer by distributing the 4 through the parenthesis and getting 4 * y - 4 * 5 = 4y - 20
2/3x -14/3 = -2 -foiled
2/3x = -6/3 +14/3 -common denominator
2/3x = 8/3
x = 8/3 * 3/2
x = 24/6
x= 4
Answer:
y = 8
Step-by-step explanation:
if you do -2 + -2 and add ten to it you get 8
