If f(x) = 11x – 5, then f^-1(x)=
MAVERICK [17]

Answer: f^-^1(x)=\frac{x+5}{11}

Step-by-step explanation:

To find the inverse, you replace the x with y, and y with x.

x=11y-5                       [add 5 on both sides]

x+5=11y                       [divide both sides by 11]

\frac{x+5}{11} =y

f^-^1(x)=\frac{x+5}{11}

In Exercises 10–14, use the diagram to determine whether you can assume the<br> statement.
lukranit [14]

Answer:

  it depends on what he means

Step-by-step explanation:

The friend needs to clarify the meaning of "if three lines intersect each other." If Line A intersects lines B and C, there will be two points of intersection, one at line B and one at line C.

If those lines are all in the same plane, and B and C are not parallel, so that line B intersects line C, then there will be a total of three points of intersection.

If the point of intersection of B and C is also the point where line A intersects them, then there will be only one point of intersection.

__

So, if the meaning is "if there are three non-parallel lines in the same plane, and each intersects the other two", then the Line Intersection Postulate guarantees there will be 1 or 3 points of intersection.

If the meaning is "if there are three lines not necessarily in the same plane, and one intersects the other two (but those two don't intersect each other)", then there may be 1 or 2 points of intersection (allowing that all lines may intersect at the same point).

Build a fence around his rectangular garden. The length is 30 feet. The width is 6 yards. How many feet of fencing is needed
nadya68 [22]
The field that is being fenced in has two 30 foot sides and 2 18 foot sides. The reason they are 18 is because there are 3 feet in a yard. You would then add all 4 sides together, equaling your perimeter.

The final answer is 96 sq feet.
