a. The decrease road line verified by given function while increase in the highway The function representing the railroad miles has a negative​ slope, indicating a decrease. The function representing the highway miles has a positive​ slope, indicating an increase.

b. It is estimated that the number of railroad miles and the number of highway miles were the same during the year 1986.

Given

The function y =-1518x + 144.068 represents the railroad miles.

While the function y =-360.5x + 155.18models the number of highway miles.

For each function, x is the number of years after 1995.

The year in which it is estimated that the number of the country's railroad miles and the number of the country's highway miles were the same.

Therefore,

-1518x + 144.068=  -360.5x + 155.18

-1518x+360.5x = 155.18-144.068

1157.5x             = 11.112

                x      = 9

Then,

1995 - 9 = 1986

It is estimated that the number of railroad miles and the number of highway miles were the same during the year 1986.

A mile, sometimes an international mile or base mile to distinguish it from other miles, is an imperial unit in the United Kingdom and a standard unit of distance in the United States. both are based on the older English unit of length, which is 5280 English feet or 1760 yards. The legal mile was standardized by an international agreement between the Commonwealth of Great Britain and the United States in 1959, when it was officially redefined in SI units to exactly 1609.3 meters.

Answer:

Step-by-step explanation:

x y

2 12

6 8

10 4

14 0

18 -4

The slope is the Rise/Run, or change in y over the change in x.  Pick any two points.  I'll choose (2,12) and (18,-4),

Rise = (-4 - 12) = -16

Run = (18 - 2) = 16

Slope = Rise/Run = -16/15, or -1

The equation becomes y = -1x + b

To find b, use any of the points in the equation and solve for b.  I'll use (14,0):

y = -1x + b

0 = -1(14) + b

b = 14

The equation is y = -x + 14

Answer:

if you meant %, the answer is 2016

Step-by-step explanation:

1120 + 80% is 2016

Okay, here we have this:

Considering the provided formula and information, we are going to calculate the requested percent of college freshmen in 2010, so we obtain the following:

So since x corresponds to the number of years after 1980, in this case we will replace x with 30, since it is 30 years after 1980, we have:

p=4x/5+25

Replacing:

p=4(30)/5+25

p=120/5+25

p=24+25

p=49

So, as we can see, the model assumes that in 2010 the percentage was 49%, and the real one is 47%. It means that the model overestimates the real value by 2%.

The unknown angles are as follows:

The value of ST in the line segment is 22 units.

An angle bisector is a bisector that bisect an angles into two equal parts.

Therefore, EF is the angle bisector of ∠EFG.

The bisector divides the ∠EFG equally into ∠EFH and ∠HFG.

Hence,

∠EFH  = ∠HFG

m∠HFG = 80°

m∠EFH  = 80°

m∠EFG = 80 + 80

m∠EFG = 160°

12.

Let's find ST in the line segment.

PT = 40

QS = 12

PQ = QR = RS = x

QR + RS = QS

2x = 12

x = 12 / 2

x = 6

Therefore,

PQ = QR = RS = 6 units

PS = PQ + QR + RS

PS = 6 + 6 + 6

PS = 18 units

Hence,

ST = PT - PS

ST = 40 - 18

Step-by-step explanation:

Let x be the "integer."  We'll assume it is odd.

The next consecutive odd integer would be x+2.

(2(x+2) - x) =9    [When an integer is subtracted from 2 times the next consecutive odd integer the difference is 9]

(2(x+2) - x) =9

(2x+4) - x) =9

x+4 =9

x = 5

The greater integer is x+2 or 7

Check:

If 5 is subtracted from 2 times the next consecutive odd integer, 7, is the difference 9?

2*7 - 5 = 9?

14 - 5 = 9?

14 - 5 = 9?  YES

As a result, 5 players' points in 1 round equal 5P.

Equation (ii) yields the range of

0 ≤ 5p ≤ 50.

As a result, Elena's team's points total ranges from 0 to 50.

(2) If each shot is off by one point, then

One player's points in one round are equal to 10-1=9.

So, 9 x 5 = 45 points were collected by 5 players in 1 round.

(3) Assume that R represents the number of teams as an integer.

the game involves at least three teams, therefore

R ≥ 3 ...( iii)

Given that N players make up one team,

R team has NR players, where R is 3, 4, or more.

Next, using equation (i)

3R ≤ 5R

Therefore, the number of players ranges from 3R to 5R if there are at least 3 teams.

The game can have anywhere from 3x3=9 to 5x3=15 players when R=3.
