I believe 25
from a trick I learned, if I remember correctly
when it come to scales 
in order to find the area u multiply the scale by itself
in this situation 5x5
therefore it is 25 times larger

The range of the transformation function f(x,y)= (x+5,y-8) is (10,8), (-2,7), and (7,9) which point is in the domain
swat32

We get that the domain will be {-7, 2, 5}.

We are given a transformation function:

f ( x , y ) = ( x + 5 , y - 8 )

Also, we are given the points in this transformation function as:

(10, 8), (-2, 7) and (7, 9)

Now, we have to find the point that lies in the domain of the function.

We have:

x + 5

Also, the values of x + 5  are given as 10, -2 and 7.

For (10, 8)

x + 5 = 10

x = 10 - 5

x = 5

For (-2, 7)  

x + 5 = -2

x = - 2 - 5

x = - 7

For (7, 9)

x + 5 = 7

x = 7 - 5

x = 2

So, domain is {-7, 2, 5}.

Therefore, we get that the domain will be {-7, 2, 5}.

In his suitcase, Jack has 3 shirts, 4 pants, 2 socks (pairs of socks), and 2 shoes (pairs of shoes). How many unique ways can Ja
kipiarov [429]

Answer:

48

Step-by-step explanation:

the number of shirts are 3, number of pants 4, number of socks pairs 2 and 2 pairs of shoes.

first lets start with shirts and pants, number of unique combinations are,

(for each shirt there are 4 different pant combinations) = (3)(4)

=12

similiarly for each shirt pant pair there are 2 shoes and 2 socks pairs.

thus, total number of combinations are=

(12)(2)(2)

= 48

A rectangle has a perimeter of 80. if the length is four more than twice the width, what is the length of the rectangle ​
zubka84 [21]

Answer:

28

Step-by-step explanation:

l = length

w = width

p = perimeter

w = w

l + l + w + w = p (adding all the rectangle's sides together gets us our perimeter)

l = 2w + 4 (four more than twice the width)

Substitute 2w + 4 for 'l' in the original equation

(2w + 4) + (2w + 4) + w + w = 80

Solve equation normally:

6w + 8 = 80

6w = 72

w = 72/6 = 12

(w = 12)

Length = 2w + 4

Substitute 12 for 'w':

2(12) + 4 = l

24 + 4 = l

28 = l

The length is 28
