Answer:

If the graph of a function f is known, it is easy to determine if the function is 1 -to- 1 . ... If no horizontal line intersects the graph of the function f in more than one point, then the function is 1 -to- 1 . A function f has an inverse f−1 (read f inverse) if and only if the function is 1 -to- 1 .

Using the following image, solve the problems below given that Q is the midpoint of PR.​
DochEvi [55]

Answer:

x=18

pq=101

qr=101

pr=202

Step-by-step explanation:

6x-7=5x+11

+5x pasa a restar como -5x al primer miembro y -7 pasa como +7x al segundo miembro y la ecuacion quedaria asi:

6x-5x=11+7

6x-5x=x

11+7=18

entonces x=18

pq=6x-7

pq=6(18)-7

pq=108-7

pq=101

y como se sabe que pq=qr porque hay un punto medio y dos segmentos cuando los divide un punto medio esos dos segmento miden igual entonces

por eso pq=qr

y como pq=101  qr=101

por ultimo

pr=pq+qr

pr=101+101

pr=202

The length of a rectangle is 7 more than the width. The area is 744 sqaure yards, find the length and width of the rectangle
Lina20 [59]

The length of rectangle is 31 yards and width is 24 yards.

Step-by-step explanation:

Given,

Width of rectangle = w

Length of rectangle = w+7

Area of rectangle = 744 square yards

Area = Length * width

744=w(w+7)\\744=w^2+7w\\0=w^2+7w-744\\w^2+7w-744=0

Factorizing the equation

w^2+31w-24w-744=0\\w(w+31)-24(w+31)=0\\(w+31)(w-24)=0

Either,

w+31=0,    =>w= -31

Or,

w-24=0     =>w=24

As width cannot be negative, therefore,

Width = 24 yards

Length = w+7 = 24+7 = 31 yards

The length of rectangle is 31 yards and width is 24 yards.

FrozenT [24]

Answer:

1st markdown = ​$324

2nd markdown = ​$259.20

Step-by-step explanation:

current price = 360

1st 6 months = 10% down

                     = 90% of 360

                     = <u>324</u>

2nd 6 month = 20% down of first 6 month

                      =  20% down of 324

                      =  80% of 324

                      = <u>259.20</u>
