Answer:x-12
Step-by-step explanation:
Area=x^2-8x-48
Width=x+4
length=area/width
length=(x^2-8x-48)/(x+4)
length=((x+4)(x-12))/(x+4)
length=x-12
Answer: dot plot 1 is 6
dot plot 2 is 15
dot plot 3 is 13
dot plot 4 is i dont know
Step-by-step explanation:
You break it down into steps. FIrst do the X's. 5x-3x=2x Then you add 18 to both sides and your equation looks like this 2x=22 Divide by 2 on both sides and x=11
The inverse relation of the function f(x)=1/3x*2-3x+5 is f-1(x) = 9/2 + √(3x + 21/4)
<h3>How to determine the inverse relation?</h3>
The function is given as
f(x)=1/3x^2-3x+5
Start by rewriting the function in vertex form
f(x) = 1/3(x - 9/2)^2 -7/4
Rewrite the function as
y = 1/3(x - 9/2)^2 -7/4
Swap x and y
x = 1/3(y - 9/2)^2 -7/4
Add 7/4 to both sides
x + 7/4= 1/3(y - 9/2)^2
Multiply by 3
3x + 21/4= (y - 9/2)^2
Take the square roots
y - 9/2 = √(3x + 21/4)
This gives
y = 9/2 + √(3x + 21/4)
Hence, the inverse relation of the function f(x)=1/3x*2-3x+5 is f-1(x) = 9/2 + √(3x + 21/4)
