Find two points for each labeled line in the graph below. Then use those two sets of coordinate points to help you find the slope and use whichever method for finding equations that you prefer to find the equation of each line listed. You only need to write the equation of each line for your answer. Remember, you must first put the equations in slope-intercept form. Label your answers m and b to represent the slope and y-intercept.

Answer:

the equation to find slope is (y2-y1)/(x2-x1)

A: (-4,1) (0,3) (for all of these except for the last one, i included the y-intercept as one of the points)

3-1/0-(-4)

2/4

m=1/2

y= 1/2x +3

B: (0,-1) (3,1)

3-0/1-(-1)

m=3/2

y= 3/2x -1

C: (0,-3) ( 6,-1)

-1 -(-3) / 6-0

2/6

m= 1/3

y = 1/3x -3

D: (3,-3) (6,0)

0 -(-3) / 6-3

3/3

m= 1

y -y1 = m (x - x1) (this is point-slope form, plugging in the slope and a point on the line, and then solving it will give you slope-intercept form)

y - 0 = 1(x -6)

y = 1x -6

Courtney walks 1 mph slower than Brandi does. In the time that it takes Brandi to walk 6.5 mi, Courtney walks 5 mi. Find the speed of each person

Answers

Answer:

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

Step-by-step explanation:

Let x = Courtney's walking speed

then

(x + 1) = Brandi's walking speed

Time = Distance/speed

Brandi walks 6.5 mi time = Courtney walks 5 mi time

6.5/x + 1 = 5/x

Cross multiply

6.5x= 5(x+1)

6.5x= 5x + 5

6.5x - 5x = 5

1.5x = 5

x = 5/1.5

x = 3.33 mph is Courtney's walking speed

Note that:

(x + 1) = Brandi's walking speed

3.33mph + 1 = 4.33mph

Therefore,

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

The Courtney's walking speed = 3.33 mph. Brandi's walking speed = 4.33 mph.

We have given that,

[tex]6.5x - 5x = 5[/tex]

Courtney's walking speed = 3.33 mph

Brandi's walking speed = 4.33 mph

Let x = Courtney's walking speed

then (x + 1) = Brandi's walking speed

What is the formula time?

Time = Distance/speed

Brandi walks 6.5 mi time = Courtney walks 5 mi time.

[tex]6.5/x + 1 = 5/x[/tex]

Cross multiply

[tex]6.5x= 5(x+1)[/tex]

Simplify parenthesis right side

[tex]6.5x= 5x + 5[/tex]

1.5x = 5

Isolate x.

x = 5/1.5

x = 3.33 mph is Courtney's walking speed

(x + 1) = Brandi's walking speed

3.33 mph + 1 = 4.33 mph

Therefore,Courtney's walking speed = 3.33 mph

Brandi's walking speed = 4.33 mph

Which fractions is greater than 1/2?
2/3
3/4
2/6
1/3
3/8
5/8
1/4
5/6

Answers

Answer: 2/3, 3/4, 5/8, 5/6

Step-by-step explanation:

First,

We must turn all of them into denominators that can be divided by 1/2.

2/3 = 4/6. 3 1/3 = 2/6

Now we see which is greater.

2/3 > 1/2.

3/4 > 1/2.

2/6 < 1/2.

1/3 < 1/2.

3/8 < 1/2.

5/8 > 1/2.

1/4 < 1/2.

5/6 > 1/2.

So the answers are 2/3, 3/4, 5/8, 5/6.

The spring concert at a certain high school sold 149 tickets. Students were charged $2 each and adults $6 each. The income from the sale of tickets was $626. How many students and how many adults bought tickets?

Answers

The final statement is: 67 student tickets and 82 adult tickets were sold.

What are linear equations?

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: Total tickets =149 student ticket=$2 and adult ticket=$6

Tickets sold worth=$626

Let x tickets be bought by students and therefore 149-x be brought by adults then we have

2x+6(149-x)=626

-4x+894 = 626

x=268/4

x=67

∴ x=67 & 149-67=82

Hence, 67 student tickets and 82 adult tickets were sold.

The admission tickets to an exhibition at $5 for an adult and $2 for a child.

A family of 3 adults and 4 children visited the exhibition.

To Find :

What would be the charge if $50 note was used to buy the tickets.

Charge of 3 adult ticket is, A = $( 5 × 3 ) = $15 .

Charge of 4 children ticket is, C = $( 4 × 2 ) = $8 .

Total amount to pay is :

T = $( 15 + 8 )

T = $23

Jacob decided to start saving for college. After 3 months, he had saved $174. His friend Victoria was inspired to do the same. After 6 months, she had saved $360. If they are both saving money at a constant rate, how many more dollars per month does Victoria save than Jacob?

Answers

Answer:

$2 more.

Step-by-step explanation:

In this question, we have to find how much more money Victoria is saving.

We know that Jacob saved $174 in 3 months.

We also know that Victoria saved $360 in 6 months.

Lets find how much money they save per month:

Jacob:

174 ÷ 3 = 58

Victoria:

360 ÷ 6 = 60

Jacob is saving $58 per month and Victoria is saving $60 per month.

This means that Victoria is saving $2 more than Jacob per month.
