Answer:
is in explanation.
Step-by-step explanation:
Our function is f(x)=2x-6.
Shifts f(x) 4 units down streches- g(x)=2x-10
To get this we move up function f(x)=2x-6-4=2x-10
streches f(x)by a factor 4- g(x)=8x-24
There multiply function by 4: 4(fx)=4(2x-6)=8x-24
shifts f(x) 4 units right-2(x-4)-6=2x-8-6=2x-14=g(x)
There is no such real number!
a+b=-5
ab=625
a=-b-5
(-b-5)*b=625
-b^2-5b=625
b^2+5b+625=0
b=-5+-sqrt(25-2500)
This resulting in b as a complex number which means in the real numbers there is no such solutions!
The answer is Two students are the same age but have different heights. Hope this helps!
Answer:
The probability of select randomly a red or a blue marble is
Step-by-step explanation:
The probability of an event is the ratio of the number of ways it can happen, to the total number of possible cases.
Select randomly a red or a blue marble are mutually exclusive events because they cannot occur at the same time. When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event.
We know from the information given that
- There are 46 red marbles, 59 white marbles and 49 blue marbles
We can use this information to calculate the probability of select randomly a red marble and also the probability to select randomly a blue marble
Now we can calculate the probability that we select a red or a blue marble
