PLEASE HELP ME ASAP!!!!
yKpoI14uk [10]

<u>Part A</u>

<u />\overline{AC} and \overline{BD}

<u>Part B</u>

Diagonals of a parallelogram bisect each other, so

BE=ED \implies 2x+3=3y-4 \implies 3y=2x+7 \implies y=\frac{2}{3}x+\frac{7}{3}\\\\AE=EC \implies y+4=4x-6 \implies y=4x-10

Solving by substitution,

\frac{2}{3}x+\frac{7}{3}=4x-10

Multiplying both sides by 3,

2x+7=12x-30\\\\37=10x\\\\x=3.7

So, y=\frac{2}{3}\left(\frac{37}{10} \right)+\frac{7}{3}=\frac{24}{5}

<u>Part C</u>

<u />BE=ED=2(3.7)+3=10.4\\\\AE=EC=4(3.7)-6=8.8

\therefore BD=2(10.4)=20.8, AC=2(8.8)=17.6

If f(x)=2x+3÷2,find f-1(x).​
BartSMP [9]

The required inverse function  f^{-1}(x) = (2x - 3 ) / 4.

Given that,
f(x) = (2x+3) / 2

To find  f^{-1}(x)

<h3>What are functions?</h3>

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Let f(x) = y
y = (2x + 3) / 2
y * 2 = 2x + 3
2y - 3 = 2x
x = (2y - 3) / 2
Now replace y = x and x = f^{-1}(x)
 f^{-1}(x) = (2x - 3 ) / 4


Thus,  the required inverse function  f^{-1}(x) = (2x - 3 ) / 4.

Y &amp; X vary directly if the constant of variation is 4 then what is the value of x when y equals 6
shepuryov [24]
I think that x would be 1.5.
6 = 4x, 6/4 = 1.5, so 1/5 = x
