Answer:

-3x-3

Step-by-step explanation:

We want our equation to look like this

y=mx+b

we know that m= -3 so we just need to find b

We can start by plugging in the ordered coordinates into our equation

3=(-3)(-2)+b

Solve for b

3=6+b

b= -3

Which means our final equation is

y= -3x-3

Step-by-step explanation:

Jupiter lighthouse , r=18 miles, A= 2*3.14*r^2

A Jupiter=2*3.14*18*18=2034.72 mi^2

Hillsborough light house, r= 28 miles,

A Hillsb=2*3.14*28*28=4923.52 mi^2

the difference is

4923.52-2034.72=2,888.80

Using the relation between velocity, distance and time, it is found that it will take her 6 hours to get to the arch.

Velocity is distance divided by time, that is:

v = d/t.

For this problem, we have that:

We can solve the equation for t to find the time, hence:

65 = 390/t

65t = 390

t = 390/65

t = 6.

It will take her 6 hours to get to the arch.

Answer:

7/13

Step-by-step explanation:

if 1/26 is closest to zero then 7/13 is closer to 1/2

This won't be the easiest way to do this problem but as your teacher requires it I will do it that way. But at the end I will show another way to do it with the quadratic formula.

First complete the square

x^2-3x+1=0

(x^2-3x+9/4)+1=9/4

(x-3/2)^2=9/4-1

(x-3/2)^2=5/4

x-3/2=±[tex]\sqrt{\frac{5}{4}[/tex]

x= 3/2±[tex]\frac{\sqrt5}{2}[/tex]

Done!

*Now this next way is not the way your teacher wants you to do it but I personally think its easier.

Just use the quadratic formula x=[-b±sqrt(b^2-4ac)]/2

x=[3±sqrt(9-4*1*1)]/2

x=(3±sqrt5)/2

x=3/2±sqrt5/2

We get the same answer but I think this way is easier. Now if your teacher ask for the top way just do the top way don't do the bottom because you will lose points, its just a shorter way to do things. Now I hope this helped and any additional questions about this just ask me in the comments.

Step-by-step explanation:

The expressions are simplified and factored in as below.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The expressions are simplified as,

1.

5x + 3x

= 8x

2.

2x + x

= 3x

3.

6x + 8x

= 14x

4.

9x + 3x

= 12x

5.

7x + 4x

= 11x

6.

10x + x

= 11x

7.

3x + 2 + 4x

= 7x + 2

8.

15x + 3 + x

= 16x + 3

9.

2x + 5 + 6x

= 8x + 5

10.

7x + 2x + 4

= 9x + 42

11.

18x + 3x + 9

= 21x + 9

12.

6x + x + 8

= 7x + 8

13.

21x + 15y

= 3(7x + 5y)

14.

2x + 14y

= 2(x + 7y)

15.

15x + 10y

= 5(3x + 2y)

16.

12x + 18y

= 6(2x + 3y)

17.

10x + 30y

= 10(x + 3y)

18.

6x + 14y

= 2(3x + 7y)

19.

8x + 16y

=  8(x + 2y)

20.

45x + 27y

= 9(5x + 3y)

21.

54x + 48y

= 3 (18x + 16y)

Thus,

Answer: 3200 ft^2

Step-by-step explanation:

You have a total area of 4,000 ft^2.

In your plan, you will make two bathrooms (one men's restroom and one women's restroom)

We know that each one of them needs 400ft^2, then the total area needed is two times 400ft^2, or:

2*400ft^2 = 800ft^2

If we subtract this to the total area, we get:

4000ft^2 - 800ft^2 = 3200 ft^2

That is the square feet left for the development of other nonbathroom areas.
