Answer:

x = 7

Step-by-step explanation:

40/16 = 2.5 scale factor that it's being enlarged by. So, 16 x 2.5 =40

45/2.5 = 18

2x + 4 = 18

- 4 both side

2x = 14

÷2 both side

x = 7

Answer:

<h2>x=7</h2>

Step-by-step explanation:

all the difference between these polygons is that the left one is 2.5x bigger than the one on the right (I found this out by doing 40/16 which is 2.5)

so now I need to divide 45 by 2.5

45/2.5=18

Now I know that

2x+4=18

-4 from both sides

2x=14

divide by 2

x=7

Mnenie [13.5K]
Assume that you only include whole numbers (1,2,3,4,5,6,7,8,9) and not 3.5 and such
so if 1 is odd and less than 5 then it is
1 or 3, since 5 isn't included
then the other number, to be less than 5 when added,
must be
1+x<5
3+x<5
solve each
1+x<5
subtract 1
x<4
set of answers are 1,2,3

3+x<5
subtract 3
x<2
set of answer is 1
so the possible numbers are
1,2,3
that is 3 numbesr out of 9 so
probability=(total desired outcomes)/(total possible outcomes) so
disred outcomes=3
total possible=9
3/9=1/3
the probabiltiy is 1/3

What are the domain and range for this graph?
RideAnS [48]

ANSWER

c. Domain: [0,18]

Range: [0,360]

EXPLANATION

The domain refers to the values of x for which the function is defined.

The given straight line graph is defined for x=0 to x=18.

Hence the domain is [0,18]

The range refers to the values of y for which x is defined.

The graph is defined for y=0 to y=360.

The range is [0,360]
