Answer: 50 cents
Step-by-step explanation:
Company charges 8 cents per call and the call in question is 3 minutes. Cost is;
= 3 * 8
= 24 cents
Company however stipulates that a call is 8 cents per minute or a 50-cent minimum charge per completed call, whichever is greater.
<em>50 cents is greater than the per minute total charge of 24 cents so the cost will be 50 cents.</em>
Answer:
Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).
Step-by-step explanation:
Misha's group was asked to write an expression equivalent to
7y²z + 3yz² - 3
When Mr. Chen checked their answers, he found only one to be correct.
And she was Helena.
Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).
Because, (7y²z + 6yz²- 5 - 3yz² + 2)
= 7y²z + (6yz² - 3yz²) - (5 - 2)
= 7y²z + 3yz² - 3 (Answer)
or 
divide both sides by 2
sinΘ = - 
Since the sin ratio is negative then Θ is in third / fourth quadrants
Θ = 
() = 
related acute angle
Θ = ( π + ) =
or Θ = ( 2π - ) =
Answer:
x-int: (2, 0)
y-int: (0,8)
(8-0)/(0-2)= 8/-2= -4
y - 0 = -4(x - 2)
y = -4x + 8
