Answer:
C)
Step-by-step explanation: This is probably bad advice, but in this question, all you need to do is find the x-coordinate. You can see that the first x-coordinate is -4, and the second one is 3. That means the midpoint's x-coord will be |-4 - 3| = 7. Knowing that, just subtract 7/2 from 3, which gives you -0.5 for the x-coord. Since there's only one option with that x-coord, you know the answer must be C.
Answer:
Option 2 is correct.
Step-by-step explanation:
We have been provided a table of values of an exponential function and we are asked to find out the decay factor of the function.
Upon looking at our table we can see that every time x increases by one our y value remains one-third of the previous value.
To find out decay factor we will subtract 1/3 from 1.
Therefore, decay factor of the exponential function is 
and option 2 is correct choice.

Since this is a multi-part question, just look at the bolded parts under each letter. I hope this helps a bit ;)
Step-by-step explanation:
A)
All sides of a square are congruent. "s" represents the square's perimeter:
s=4x.
"r" is the rectangle's perimeter:
r= 4x+26
since the perimeter = 2W + 2L:
2W + 2L= 4x+ 26
and W=x, so:
2x + 2L= 4x + 26
Subtract from both sides:
2L= 2x +26
Divide both sides:
the length of the rectangle "L"= x +13.
B) Plug 5 into the equations:
L= 5+ 13 or 18.
2(18) + 2(5)= r
36+ 10 = r or 46
s= s+ 26
s= 46-26 or 20.
20/4= 5...
It seems (at least to me, feel free to give constructive criticism) that the only logical conclusion is that 5 <u>could</u> be the value of x.
C) You would likely need to use substitution to solve, but unless I am much mistaken, this looks like an infinite-solutions equation.
L=w+13
Answer:
It should be the second one
Step-by-step explanation:
Hello There!
The third missing length would be 68°
All sides of a triangle always add up to 180°
We take the two sides we do know, add them together and then subtract the two sides added together from 180°
