Justice hopes to build a fence around his garden he measures and determined that he needs 24 feet of fencing when he arrives at

Sunny_sXe [5.5K]

Answer:

It will cost $72 Justice to fence in his garden.

Step-by-step explanation:

Total length of the fencing around the garden = 24 feet

Cost of fencing per inch = $0.25

Now, as we know 1 foot = 12 inches

⇒ 24 feet = 24 x 12 inch = 288 inches

⇒ 24 feet = 288 inches

Hence, the total length of fencing = 288 inches.

Now, Total cost of Fencing

=Total length of fencing x Cost of fencing par inch

= 288 inches x ($0.25)

= $ 72

or, the total cost of fencing = $72

Hence, it will cost $72 Justice to fence in his garden.

Given the domain (-2,2,4) what is the range for the relation 3x-y=3

Bumek [7]

Answer:

Given the domain, the range for 3x-y = 3 is {-9, 6, 9}

Step-by-step explanation:

First you have to put the relation in terms of y ⇒ 3x - y = 3⇒ 3x -3 = y

⇒ y = 3x - 3.

Then you replace the values indicated by the domain to find their "y" values (the ones that constitute the range).

f(-2) = -9

f(2) = 6

f(4) = 9.

Finally, the range for the given domain is {-9, 6, 9}

Thx in advance for the help

lubasha [3.4K]

Answer: $x\geq 13$

Step-by-step explanation:

Given

The inequality is $2x-7\geq 19$

adding both side 7

$2x-7+7\geq 19+7\\2x\geq 26$

Multiply both sides by $\frac{1}{2}$

$\dfrac{1}{2}\times 2x\geq 26\times \dfrac{1}{2}\\\\x\geq 13$

the shaded region in the figure indicates the solution set.
