I think it is because if you divide by a negative you which the sign ?
A. is not a real number, or square root -3
Negative numbers do NOT have a square root because it is negative
Find the median of 6,2,0,1,1,2,3,2,0,2,3,4,2,3,5
neonofarm [45]
The median is 2
Median = Middle
First, arrange the numbers from lowest -> highest
This would be:
0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6
Now, strike off one number from each side (so 0, then 6, then 0, then 5) until you are only left with one or two numbers.
If you are left with one number, that is your median!
If you are left with two numbers, than you add them together, then divide that number by 2 (for example if you were left with 7 and 8, 7+8=15. 15/2=7 1/2)
In this case, you are left with one number, 2, so 2 is your median.
I hope this helped!
Answer:
k = 13
smallest zero = -6
Step-by-step explanation:
f(x) is basically the function of x.
x could be any integer. f(x) is the solution of the function of x.
f(x) is defined as x² + 3x - 10
f(x) = x² + 3x - 10
Now, f(x+5) = x² + kx + 30
This statement here says that if the value of x is x+5, then the answer would be x² + kx + 30.
f(x) = x² + 3x - 10
f(x+5) = (x+5)² + 3(x+5) - 10
f(x+5) = x² + 10x + 25 + 3x + 15 - 10
f(x+5) = x² + 13x + 40 - 10
f(x+5) = x² + 13x + 30
x² + 13x + 30 = x² + kx + 30
hence, k = 13
Smallest zero = The smallest x value.
f(x+5) = x² + 13x + 30
Let's take f(x+5) = 0
x² + 13x + 30 = 0
which two numbers products give us 30 and add up to 13?
== 6 and 5
(x+6)(x+5) = 0
x+6 = 0
x = -6
x+5 = 0
x = -5
The two solutions are -6 and -5
The smallest out of these two is -6.
Answer: 2a/3 + b/3
Since it has two different variables, there is no final answer. To find the answer, you must first expand the equation and then apply the fraction rule.
