Answer: x=24
Step-by-step explanation:
First, we can write this problem into a <em>mathematical equation </em>where x is you number:
<em>Eight more than 2 times your number is 56.</em>
<u>2x+8=56 </u>
Now, we can <em>solve</em> this equation for x.
<em>Subtract 8 from both sides and divide it by 2.</em>
2x=48
<u>x=24</u>

Answer:
y=-1/6x + 0 or y=-1/6x (when b = 0 then you leave it out)
Step-by-step explanation:
Find the slope:
-0.5 - 0.5/3 - (-3) = -1/6
Find the y intercept (b): Plug in the x, y and m into y= mx + b
0.5=(-3)(-1/6) + b
0.5=1/2 + b
0.5-0.5 = b (change the 1/2 into a decimal 0.5 to make it easier to subtract
0=b
Now plug in the m and the b that you just found into the equation y=mx+b
y=-1/6x + 0 or y=-1/6x (when b = 0 then you leave it out)
Answer:
5
Step-by-step explanation:
We have that
<span>(c-4)/(c-2)=(c-2)/(c+2) - 1/(2-c)
</span>- 1/(2-c)=-1/-(c-2)=1/(c-2)
(c-4)/(c-2)=(c-2)/(c+2)+ 1/(c-2)------- > (c-4)/(c-2)-1/(c-2)=(c-2)/(c+2)
(c-4-1)/(c-2)=(c-2)/(c+2)---------------- > (c-5)/(c-2)=(c-2)/(c+2)
(c-5)/(c-2)=(c-2)/(c+2)------------- > remember (before simplifying) for the solution that c can not be 2 or -2
(c-5)*(c+2)=(c-2)*(c-2)------------------ > c²+2c-5c-10=c²-4c+4
-3c-10=-4c+4----------------------------- > -3c+4c=4+10----------- > c=14
the solution is c=14
the domain of the function is (-∞,-2) U (-2,2) U (2,∞) or
<span>all real numbers except c=-2 and c=2</span>
