Answer:
-1/10
Step-by-step explanation:
We need to get a common denominator of 10
-1/2 *5/5 = -5/10
2/5*2/2 = 4/10
-5/10 +4/10 = -1/10
Answer:
The Z is has no lines of symmetry. The W and Y have one line of symmetry. The X has two lines of symmetry.
Absolute value would be 35!
Answer:
The function
is continuous for all real numbers
Step-by-step explanation:
To know the possible points of discontinuity of this function, we must find out when the denominator of the function is equal to 0.
The denominator is:

Then we equal 0 and clear x

for any real number.
This means that
<em>for all reals numbers</em>.
Therefore, the function
is <em>continuous</em> for all real numbers, that is, it does not have discontinuities.

Answer:
(3y+2)(y+7)
Step-by-step explanation:
I think you meant (y+7)+3y(y+7)+(y+7). Anyways, we have to count the number of (y+7) there are. The first term tells us we have 1 group. The second term tell us we have 3y groups. The last term tells us we have 1 group. Therefore we have 1+3y+1 groups of y+7 which gives us (3y+2)(y+7)
