Answer:
B
Step-by-step explanation:
So we have the expression:
Since 5 goes into both 15 and 50, we can factor out a 5. First, rewrite the numbers as:
Factor out the 5:
So, our answer is B
And we're done!
Answer:
Step-by-step explanation:
eight less then the product of a number and 2
" the product " means multiply
the product of a number and 2.......2x
eight less....-8
2x - 8 <=== ur expression
Answer:
C. 63.4
Step-by-step explanation:
Answer:
f(x)=-|x|
Step-by-step explanation:
We have been given a graph of f(x) which resembles with the graph of function g(x) where g(x)=|x|.
It says that graph is flipped over the x-axis.
Now we have to find about which of the following choice correctly describes the given graph.
We know that |x| means absolute value of x so that means g(x)=|x| is absolute function in shape of V.
We know that flipping over x-axis can be done by changing f(x) into -f(x).
<u>Hence correct answer is choice D) F(x)=-|x|</u>
Answer:
Step-by-step explanation:
sqrt(28): sqrt(4*7)
sqrt(4) = 2;
sqrt28)=2*sqrt(7)
sqrt(343): sqrt(7 * 7 * 7) = 7 * sqrt(7)
Note: the rule is if you have 3 equal primes under the root sign, you leave one, you throw one away, and you put one outside the root sign.
2 sqrt(63) = 2 sqrt(3*3*7) The above rule gets modified to throw 1 three away and take the other one outside the root sign.
2sqrt(63) = 2*3 sqrt(7)
Numerator: 2*sqrt(7) + 7sqrt(7) = 9sqrt(7)
9sqrt(7)
======
6 sqrt(7)
3/2
Note without brackets I cannot be certain that I have interpreted this correctly. The division only apply to sqrt(343) / 2 sqrt(63). If this is so please leave a note.
