Step-by-step explanation:

Alexandria High School scored 37 points in a football game. Six points are awarded for each touchdown. After each
touchdown, the team can earn one point for the extra kick or two points for a 2-point conversion. The team scored one
fewer 2-point conversions than extra kicks. The team scored 10 times during the game. How many touchdowns were
made during the game? Write and solve a system of equations to get your answer.

Answers

Answer:

Five touchdowns were made in the game

Step-by-step explanation:

Here, we want to know the number of touchdowns made during the game.

We proceed as follows;

Let the number of touch downs be x

So the total points earned through touchdowns is 6 * x = 6x

The number of scores is 10 times

Let the number of extra kick be y which means that the number of conversions will be (y-1)

So the total number of score times will be ;

x + y + y-1 = 10

x + 2y = 11 •••••••••(i)

Now let’s work with points

Touch down points = 6 * x = 6x

Points from extra kick = 1 * y = y

Points from 2-point conversions = 2(y-1) = 2y - 2

So;

6x + y + 2y -2 = 37

6x + 3y = 37 + 2

6x + 3y = 39

divide through by 3

2x + y = 13 •••••••(ii)

So now solve simultaneously

From ii, y = 13 - 2x

Put this into i

x + 2(13-2x) = 11

x + 26 - 4x = 11

x -4x = 11-26

-3x = -15

x = -15/-3

x = 5

There are five touchdowns in the game

There are Five touchdowns were made during the game.

Here,

Alexandria High School scored 37 points in a football game. Six points are awarded for each touchdown.

After each touchdown, the team can earn one point for the extra kick or two points for a 2-point conversion.

The team scored one fewer 2-point conversions than extra kicks. The team scored 10 times during the game.

We want to know the number of touchdowns made during the game.

What is system of equations?

A system of equations is a collection of two or more equations with a same set of unknowns.

Now,

Let the number of touch downs be x

So, the total points earned through touchdowns is;

6 * x = 6x

The number of scores is 10 times

Let the number of extra kick be y which means that the number of conversions will be (y-1)

So, the total number of score times will be ;

x + y + y - 1 = 10

x + 2y = 11 •••••••••(i)

Now let’s work with points

Touch down points = 6 * x = 6x

Points from extra kick = 1 * y = y

Points from 2-point conversions = 2(y-1) = 2y - 2

Hence;

6x + y + 2y -2 = 37

6x + 3y = 37 + 2

6x + 3y = 39

divide through by 3

2x + y = 13 •••••••(ii)

So, now solve this;

From ( ii ), y = 13 - 2x

Put this into ( i )

x + 2(13-2x) = 11

x + 26 - 4x = 11

x -4x = 11-26

-3x = -15

x = -15/-3

x = 5

Hence, There are Five touchdowns were made during the game.

Step-by-step explanation:The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet " ⇒ D

Step-by-step explanation:

The boiling point of water (measured in degrees), at altitude (measured in feet), is modeled by the function T(a) = −0.0018 a + 212, where

a is the altitude measured in feet

T(a) is the boiling point of water in degree

The form of the linear function is f(x) = mx + b, where m is slope (the rate of change), and b is the y-intercept (the value of f(x) at x = 0)

By comparing between the form of the function and the given function

∴ m = -0.0018 ⇒ degrees per foot

∵ The sign of the slope is negative

∵ The slope = Δf(x)/Δx

- That means T(a) is decreasing function

∴ The boiling point is decreases when the altitude increasing

∵ -0.0018 =  degrees per feet

∴ The boiling point decreases by 18 degrees as the altitude

   increases by 10,000 feet or the boiling point decreases by 1.8

    degrees as the altitude increases by 1,000 feet

The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet "

A line with a slope of -1/4 passes through the point (8,7). What is it's equation in slope- interception form?

Answers

Answer:

y= -1/4x + 9

Step-by-step explanation:

When given the point (8,7) and the slope -1/4, you have to convert this into a formula called point slope form. This is the formula:

y - y1 = m(x - x1)

First, label the given information.

-1/4= m (slope)

8= x1 (the first x given)

7= y1 (the first y given)

Then, plug in the values into the equation

y - 7 = -1/4(x - 8)

After, do the property of distribution by multiplying the -1/4 with whatever is in the bracket

-1/4 multiplyed by x= -1/4x

-1/4 multiplyed by -8= 2

Next, bring the 7 to the other side of the equal sign by adding the 7 from one side to the 2. Then combine like terms

y - 7 = -1/4x +2

 +7            +7  

This gets you your answer:

y = -1/4x +9
