Answer:
I want to say it's -69/100
Step-by-step explanation:
Hope that helps!
20%
Because Suppose x% of 20 is 4
That is
x100×20=4
or
x5=4
—> =4×5=20
So 20% of 20 is 4

Answer: x = ¹/₂ ± √⁸¹

Step-by-step explanation:
First write out the equation
x² - x - 20
Now we now write the equation by equating to 0
x² - x - 20 = 0
We now move 20 to the other side of the equation. So
x² - x = 20,
We now add to both side of the equation square of the half the coefficient of the (x) and not (x²) which is (1) . So, the equation now becomes
x² - x + ( ¹/₂ )² = 20 + ( ¹/₂ )²
x² - ( ¹/₂ )² = 20 + ¹/₄
( x - ¹/₂ )² = 20 + ¹/₄, we now resolve the right hand side expression into fraction
( x - ¹/₂ )² = ⁸¹/₄ when the LCM is made 4
Taking the square root of both side to remove the square,we now have
x - ¹/₂ = √⁸¹/₄
x - ¹/₂ = √⁸¹/₂
Therefore,
x = ¹/₂ ± √⁸¹

Answer:
Michael is incorrect.
if we take the steps Michael says and move the ABCDE up 8 and right 10, not all of the points line up.
Step by step explanation:
In order to get the shapes to line up, we need to flip (reflect) ABCDE onto the 2nd Quadrant, then we can move (translate) it to the right by 10.
Answer:
D
Step-by-step explanation:
f(x) = 10x - 5 → x = 10g(x) - 5 → x + 5 = 10g(x) →
g(x) = (x + 5)/10
