Answer:

$28+56t+28w=14(2+4t+2w)\\\\28+56t+28w=28(1+2t+w)$

Step-by-step explanation:

$28+56t+28w=14\times 2+14\times 4t+14\times 2w\\\\14\ is\ common\ in\ every\ term\\\\28+56t+28w=14(2+4t+2w).........................................(1)\\\\Now\ take\ 2+4t+2w\\\\2+4t+2w=2+2\times 2t+2w\\\\2\ is\ common\\\\2+4t+2w=2(1+2t+1)\\\\Now\ substitute\ this\ in\ equation\ 1\\\\28+56t+28w=14\times 2(1+2t+w)\\\\28+56t+28w==28(1+2t+w)$

Answer:

1) The graph is as shown at the attached figure.

2) The line passes with (1,-3) and (2,-2)

Step-by-step explanation:

graph the line that passes with (3,-1) and has a y-intercept of -4

y-intercept is the value of y when x = 0

So, the line passes with (0 , -4)

The general form of the line y = mx + c

Where m is the slope and c is y-intercept

given y-intercept = -4 ⇒ ∴ c = -4

using the other point to find m

So, when x = 3 , y = -1

So, -1 = 3m - 4

Solve for m

3m = -1 + 4 = 3

m= 3/3 = 1

So, the equation of the line ⇒ y = x - 4

See the attached figure which represents the graph of the line

As shown at the graph the line passes through the points (1,-3) and (2,-2)

Town A and town B calculated the number of dogs in each town based on the average number of dogs per neighborhood. The graph bel

MAXImum [283]

Answer:

C. Town A has the greater average number of dogs per neighborhood.

Step-by-step explanation:

First, find Town A's average number of dogs per neighborhood. Since the graph is a straight line, you can find the number of dogs per neighborhood by dividing a given y-value by its x-value counterpart:

(4,60)

60 dogs / 4 neighborhoods

15 dogs / neighborhood.

Now, we must find the average number of dogs per neighborhood in Town B. Since the equation is y = 10x, where x is the number of neighborhoods, in 1 neighborhood, there are 10 dogs:

10 dogs / neighborhood.

Finally, compare the two values:

15 > 10

C. Town A has the greater average number of dogs per neighborhood.

mart [117]

Answer:

Her annual salary is $62,400

Step-by-step explanation:

Michelle Hong noticed that her gross pay per period increased by 2,800 when her employer changed from a bi weekly pay plan to a monthly pay plan.

Bi weekly is a check every 2 weeks, so she would get 26 checks per year.

Monthly would be 12 checks per year.

When she gets paid monthly her pay increased by $2,800 each check.

Let x be one bi-weekly paycheck.

The equation we get is:

12(x+2800) = 26x

Multiply the bracket by 12:

12x +33600 = 26x

Subtract 12x from both sides

33600 = 14x

Divide both sides by 14:

x = 33600/14

x = 2400

Her pay increased by 2800 each period:

2400 + 2800 = 5200 per check.

5200 x 12 months = 62400

Her annual salary is $62,400
