Answer:
f⁻¹(x) = (x - 1)/8
Or
f⁻¹(x) = 1/8 x - 1/8
Step-by-step explanation:
To find the inverse of a function, switch the "x" and "y" variables, then isolate "y".
Remember <u>"f(x)" is the same thing as "y"</u>. Change from function notation to "y".
f(x) = 8x + 1
y = 8x + 1
<u>Switch the "x" and "y" variables</u>
x = 8y + 1
<u>Isolate "y"</u>. Move the "y" variable to the left for standard formatting
8y + 1 = x
8y + 1 - 1 = x - 1 Subtract 1 from both sides
8y = x - 1
Divide both sides by 8 and simplify
Inverse equation
Slope-intercept form
<u>Use function notation</u>, change "y"
Simplified
Slope-intercept form
Answer:
maybe 14 or 15 im not good with this stuff im in 8th grade and im very very behind a lot im prob gonna delete this app cuz I dont understand anything
<span>12xy - 9x - 8y + 6 = 3x(4y-3) - 2(4y-3) = (3x-2)(4y-3)</span>
<u>Answer:</u>
The Time taken by Elena and Jade to meet up is 2.5 hours
<u>Explanation:</u>
Given,
Elena moves with a speed of 6mph while Jada walks at a speed of 4 mph
Also, Distance can be calculated by the formula

To find out the Total speed, i.e., speed of both Elena and Jada as both of them are walking in opposite direction we should add the speed of both the persons, if in same direction we should subtract the values
Here it will be:
= 10mph
Distance apart is given as 25 miles. Substituting the values,

25 = 
Time = 25/10
Time = 2.5 hour
Hence, It will take 2.5 hours to meet up.
Answer:
D. The volume of square based pyramid is 1280 
Step-by-step explanation:
Given:- A square base pyramid of,
Base edge (b) =16 inches.
Height (h)= 15 inches.
To find:- Volume of the square bases pyramid=?
Solution:-
As the given pyramid is a square based pyramid, therefore the formula to find the volume for square based pyramid is,
Volume of square based pyramid = 
where, b is the base edge and h is the height of the pyramid.
Volume of square based pyramid = 
Volume of square based pyramid = 
Volume of square based pyramid = 
Volume of square based pyramid = 1280 
Therefore the volume of square based pyramid is 1280
