Pls show work! questions on pic

a.(10,23)

b.(7,30)

e.(20,20)

Step-by-step explanation:

We are given that

x=Width of garden

y=Length of garden

According to question

Perimeter of rectangle=

Where x=Width  of rectangle

y=Length of rectangle

Fencing used =

First we change inequality  into equality

...(1)

...(2)

...(3)

Substitute x=0 in equation (3)

Substitute y=0  in equation (3)

Substitute x=0 and y=0 in equation (3)

It is true. Therefore, the  shaded region below the line.

These are false equation .Therefore, the shaded region above the line.

Substitute x=5 in equation (3)

Substitute y=20 in equation (3)

Intersection point of equation (1) and (3) is (5,35) and intersect point of equation (2) and (3) is (20,20).

Now,

a.(10,23)

Substitute in

10>5 and 23>20

it satisfied all inequality.

Hence, it is a solution.

b.(7,30)

7>5

30>20

it satisfied all inequality.

Hence, it is a solution.

c.(18,25)

18>5

25>20

It does not satisfied third inequality

Hence, it is not a solution.

d.(8,35)

8>5

35>20

It does not satisfied third inequality

Hence, it is not a solution.

e.(20,20)

20>5

20=20

it satisfied all inequality.

Hence, it is a solution.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
