One way is to subsitute the point (-1,5) for every function and see which one gives a true statement
5=10(2)^(-1) is true
5=10(0.5)^-1 is false
5=5(-1) is false
5=5(2)^-1 is false
answer is y=10(2)ˣ
Answer:
3. 15 units
Step-by-step explanation:
When medians intersect, the point of intersection divides the median into parts in the ratio 2:1. That is ...
OC : CR = 2 : 1 = 4 units : 2 units . . . . . . OR = (4+2) units = 6 units
MC : CT = 2 : 1 = 6 units : 3 units . . . . . . MT = (6+3) units = 9 units
The sum of lengths OR + MT is ...
6 units + 9 units = 15 units
Answer:
F=70.7
Step-by-step explanation:
This is a simple substitution problem.
- The formula to change Fahrenheit to Celsius is
. - They give you C, so substitute it into the problem, which would give you
. - Simplify the right side of the equation by multiplying
by 21.5. - Now, add 32 to 38.7, which should have been your answer to the previous step.
- You should now have F= 70.7 as your answer.
Answer: $5,60 will be taken off the price
Step-by-step explanation:
Take off = regular price·20/100
Take off = $28·20/100 = $560/100 = $5,60
Price after discount = $28 - $5.60 = $22.4
Answer: $5,60 will be taken off the price
