Answer:
Step-by-step explanation:
Slope m is defined as m=(y2-y1)/(x2-x1) in this case
m=(218-155)/(22-15)=63/7=9
y=mx+b
y=9x+b, using point (15,155) we can solve for the y intercept b
155=9(15)+b
155=135+b, b=20 so the line is
y=9x+20
In thirty days there will be
y=9(30)+20=290 coins
B. Find the difference between 155 and 45. The angle measures 110.
Answer:
If is not one to one is not inverse (no inverse)
Step-by-step explanation:
given that - 1 hour = 60 min
then, 25 60
then, we cut it from the table of 5 !!
therefore, 5:12
Answer:
C) [-4,0)
Step-by-step explanation:
Look at the endpoints. You have (-3,0) which isn't included in the function and you have (1,-4) which is included in the function.
We use interval notation when we are describing the subset of numbers in a function by using parentheses to show an endpoint is not included and brackets to show an endpoint is included.
In this case, since we are being asked to find the range of the function, that only pertains to y-coordinates.
Given that (1,-4) is included in the function, this means that y=-4 is included in the function. Therefore the answer's interval notation will start with a bracket to show it's included.
Given that (-3,0) isn't included in the function, this means that y=0 isn't included in the function. Therefore the answer's interval notation will end with a parenthesis to show it's not included.
Combining the two elements, we have an interval notation of [-4,0) which means C is the correct answer
