Answer:
10+2+0.3+0.05+0.007
Step-by-step explanation:
A. -(a+5)
Because the negative sign is outside the parenthesis, multiplying by -1 just removes the negative sign:
-(a+5) * -1 = a+5
B. -(-x+31)
Apply the distributive property:
-(-x+31) becomes (- -x +31) which simplifies to (x+31)
multiply that by -1 to get -x+31
C. -(4x+12)
Because the negative sign is outside the parenthesis, multiplying by -1 just removes the negative sign:
-(4x+12) * -1 = 4x+12
In a rational function, holes are located where f(x) is undefined(the denominator is 0), but the undefined points can be factored out. In f(x), when x is 4 or -3, f(x) is undefined. But, x+3 can be factored out, so it is a hole. The hole is located at (-3,-1/7)
This is awfully general. Ruben has or does something. Whatever. Let's call that Whatever "r." Then the expression in question is "r+10."
X=7/12
Alright so let's solve this! :)
••• Subtract 3w from both sides.
<span><span><span><span>5w</span>+3</span>−<span>3w</span></span>=<span><span><span>3w</span>+10</span>−<span>3w</span></span></span><span><span><span>2w</span>+3</span>=10
</span>••• Subtract 3 from both sides.
<span><span><span><span>2w</span>+3</span>−3</span>=<span>10−3</span></span><span><span>2w</span>=7
</span>••• Divide both sides by 2.
<span>2w/2</span>=<span>7/<span>2
</span></span>=<span>7/2
and then 7/2=3.5</span>
