Answer:
y=-3
Step-by-step explanation:
slope is 0 so we know it is a straight line.
your y value is -3 so therefor is your answer
Answer:
see attached
Step-by-step explanation:
It's almost easier for you to do this than it is to post a question on Brainly.
All you need to do is type the relevant expressions. Once you have Desmos show you the vertex, writing the x= equation for that is all that is required to draw it.
Answer:
No
Step-by-step explanation:
The set of integers cam be accepted as the set of negative and positive natural numbers and zero. Alternatively, the set of integers can be regarded as the set of negative and positive whole numbers including zero.
A1 = first term
a1 = 15
---------------------------------------------
d = common difference
d = (second term) - (first term)
d = a2 - a1
d = 9-12
d = -3
The negative common difference indicates that the terms are decreasing
Each time we subtract 3, or add -3, to get the next term.
----------------------------------------------
nth term of arithmetic sequence
an = a1 + d(n-1)
an = 15 + (-3)(n-1)
an = 15- 3n + 3
an = 18 - 3n
Answer is choice D
It will take them 20 hours, since the question is asking how long it will take them when working together you add each of their hours together,9+11=20
