Answer:
Your answer should be C. =)
Step-by-step explanation:
1/3*6/10=.2 which is equivalent to 1/5. Then, -21/3=-7.
Answer:
5x-2y =80
x+y=30
Step-by-step explanation:
Basically, 5x is the points earned by correct questions (5 points per right answer) and -2x is the points lost by wrong answers (2 points taken away for every wrong answer). The total points the contestant earned is 80, which is why we set this equation equal to 80. Hence, 5x-2y=80.
They also tell us that the contestant answered a total of 30 questions, so x and y combined would be the total number of questions. Hence, x+y=30.
Answer:
<u>It</u><u> </u><u>has</u><u> </u><u>two</u><u> </u><u>roots</u>
that is †2.4i and -2.4i
Step-by-step explanation:
for a root, f(x) is zero
subtract 6 from both sides:
remember: from complex numbers, i² is -1
take square root on both sides:
Answer:
6 miles
Step-by-step explanation:
Since you walked 3/4 miles in 1 day then in 8 days you walked...
3/4*8=3*2=6 miles
Answer: Second Option
Step-by-step explanation:
The function is an exponential function.
Functions of this type have a range that goes from (0, ∞)
When multiplying the function by a negative coefficient , now all the values of g(x) will be negative and the range of will be: (-∞, 0)
Then we must search among the options a function with range (-∞, 0)
Since the exponential functions of the form , where always have range (0, ∞) Then the correct option will be the one with a negative coefficient.
The correct option is the second option
