B can be 1, or b can be -5.
6 inches x 8 inches = 48 inches
48 inches x 1.5 feet = 72 feet
72 feet x $9.75 = $702 <-- Total
Answer $720
Answer:
f (
x
) −
1 =
(
1/
4 x
) −
2.
Step-by-step explanation:
For inverse function, the x and y interchanges and then make y the subject again of the equation. See the working out below:
f (
x
) = 4
x + 8
f (
x
) = y
y = 4
x + 8
x = 4
y +
8 ----- interchanging y and x
Now make y the subject of the equation:
x = 4
y + 8
−
4
y = -
x + 8
y = (
−
1/
4 )
. − x
+ (
−
1/
4 ) .8
y = (
1/
4 x
) −
2
So the inverse function is:
f (x) −
1 = (
1/
4 x
) −
2
Answer: white = $13, double = $14
<u>Step-by-step explanation:</u>
Let white chocolate chip dough = x
Let double chocolate chip dough = y
Mary: 3x + 2y = 67
Darryl: <u> -(3x + 4y = 95)</u>
-2y = -28
<u> ÷-2 </u> <u>÷-2 </u>
y = 14
3x + 2y = 67
3x + 2(14) = 67
3x + 28 = 67
<u> -28 </u> <u>-28</u>
3x = 39
<u>÷3 </u> <u>÷3 </u>
x = 13
The best in quality will probably be the 1470 but easiest to get i to is probably 1190 because if your sat score is way above their average they will think you are flaunting and deny your request
Plz mark as brainliest!
