Answer:
3. 2n - 4 = 7(n + 8)
Step-by-step explanation:
Two times a number is 2n. Four less than 2n is (2n-4). The sum of a number and 8 is (n+8). Seven times that sum is 7(n+8). The statement says these values are equal:
2n -4 = 7(n +8)
Answer:
Step-by-step explanation:
To answer this question we should analyze both functions :
- the intercepts with the x-axis are the numbers when a function f(x)=0
here we must solve both equations :
- x²=0
- x²+2=0
the first one is obvious x=0 the scond is more interesting :
x²+2=0⇔x²=-2 wich is impossible since x²≥0 unless we use complex numbers .
So we notice thatf has one intercept.
we added 2 to f to get g but no real intercepts
In order for us to find the mean of the given numbers above, what we are going to do is to add up all the numbers and divide them by the number of items. So the sum of all the numbers is 120. Now divide 120 by 12 and the answer is 10. Therefore, the answer is option D. 10. Hope this helps.
