Answer:
f(x)^-1=x+12
Step-by-step explanation:
f(x)=x-12
y=x-12
x=y-12
y=x+12
f(x)^-1=x+12
Hope it helps.
Answer:
x=3
Step-by-step explanation:
Because the line lies on x =3
Answer:
$221
Step-by-step explanation:
First we need to find what is 35% of 340. To do this, we multiply 340 by 0.35. This gives us 119. Because this is the amount they are taking off, we need to subtract it from the initial price. 340-119=221. Therefore the price after being marked down is $221 :)
Well abnormal square would have four equal sides therefore for the firemen square since it's 9 ft^2 then u square root it and u get 3 that means each side in that green square is 3 now for the red one with 16ft^2 it would be the same consept u would square root 16 which u would get 4 now the two legs are 3 and four now u are missing the hypotenuse at c thus u use pythogerom theorom I don't know how to spell it so don't complain! You would do 3^2+4^2=c^2 which would result to 9+16=c^2. From there u would add and you would get 25 =c^2 and the reverse property of square would be square root it's that radical symbol if u remember so radical 25=5. We are still not finished we have to find the area and since we are working with normal squares where each sides ar eewual then u do 5*5 u get 25!
Now don't forget to write ft2 because then u will get it wrong
And don't be a lazy bum and try rechecking my work because I did it all in my head ok it's 12 o'clock a.m.

Answer:
7/4 - 8/3 - |1/6 - 3/4|
criss cross both sides to find their respectively simplified forms.
let's do (7/4 - 8/3) first.
(4 × 8) - (7 × 3) / 3 × 4
= 32 - 21 / 12
= 11 / 12.
then simplify |1/6 - 3/4| by criss crossing the pure numbers inside the absolute value.
Remember, no number can get out of the absolute value while being negative.
= |6 × 3 - 4 / 24|
= |18 - 4 / 24|
= |14/24|
= | 7 × 2 / 12 × 2 |...cancel the 2's
= |7 / 12| --> 7/12
11 / 12 - 7 / 12
= 4 /12
= 4 × 1 / 4 × 3....cancel the 4's
= 1 / 3.
