Answer:

He will need 99  feet of fence.

Step-by-step explanation:

Jim's back yard has the following dimensions;

Length=120 feet

Width=75 feet

The gardens dimensions can be calculated using the expression;

Length of garden=Length of back yard/scale factor

where;

Length of back yard=120 feet

Scale factor=2/5

replacing;

Length of garden=120/2/5

Length of garden=12 feet

Width of garden=Width of back yard/scale factor

where;

Width of back yard=75 feet

Scale factor=2/5

replacing;

Width of garden=75/2/5

Width of garden=37.5 feet

The gardens dimension are;

Garden width=37.5 feet

Garden length=12 feet

To get the length of the fence that will enclose all four sides, we calculate the perimeter of the garden;

Perimeter=2(length+width)

Perimeter=2(12+37.5)=99 feet

He will need 99 feet of fence

Answer:

he will need 99 feet to fence

Answer:

-z+4=-4

Step-by-step explanation:

First, you want to move the positive four to the other side to isolate the variable.

-z=-8

You cannot have a negative variable, so divide both sides by 1.

-z/1=-8/1

Your answer would be:

Z=8

Step-by-step explanation:

Answer:

16: y=4x+14 17: 12 18: when you simplify it all individually you get x=3 for both equations. 19: $6.69

Step-by-step explanation:

16:y-2=4(x+3) distribute 4 and get y-2=4x-12. Add 2 to both sides to get y-4x+14.

17:x+2y=4 and 3x+6y=? divide 3x+6y by three and you get x+2y=4. This means you can just multiply the 4 by 3 to get the answer.

18:3x-5=4 and 3x-3=6. For the first one add 5 to both sides to get 3x=9 then divide both side by 3 to get x=3. For the second one add 3 to both sides to get 3x=9. Again divide both sides by three to get x=3.

19: $18-$4.62=13.38 since he wants 2 models divide 13.38 by 2 to get 6.69.

Answer: 55$

Step-by-step explanation:

Answer:

f(1) = 8

Step-by-step explanation:

x - 1 = 0

x = 1

f(x) = 2x² + 7x - 1

f(1) = 2*1² + 7*1 - 1

     = 2 + 7 - 1

     = 9 - 1

f(1) = 8

Answer: Choice A)  [tex]-\infty < x < \infty[/tex]

We can plug in any x value we want. The domain is the set of all real numbers. We don't have to worry about applying the square root of a negative value since negative values are allowed in cube roots.

For instance, [tex]\sqrt[3]{-64} = \sqrt[3]{(-4)^3} = -4[/tex]
