Answer:
.018
Step-by-step explanation:
3x+10>10 = x > 0
<span>6x-4<-34 = x < -5</span>
Method 1:
Convert the mixed number to the improper fraction:

Make the product:

<em>canceled 2</em>

Method 2:


<em>use the distributive property a(b + c) = ab + ac</em>

6.4 - 2x - 6.63x = 610.5
subtract 6.4 from both sides
-2x -6.63x =604.1
collect like terms
-8.63x = 604.1
divide both sides by -8.63
x= -70
Answer:

Step-by-step explanation:
A function satisfying the equation
is said to be an even function. This denomination comes from the fact that the same relation is satisfied for functions of the form
with
even. Observe that if
is twice differentiable we can derivate using the chaing rule as follows:
implies 
Applying the chain rule again we have:
implies 
So we have that function
is also an even function.
