Step-by-step explanation:

Step-by-step explanation:

In order to find the slope, we must follow this formula when we have 2 points.

[tex]\frac{y2}{x2} - \frac{y1}{x1} =m[/tex]

Identified 2 points:

Substitute the 2 points into the formulas format.

Then, solve by subtracting the 2 points.

[tex]\frac{-1}{1} -\frac{1}{0} =\frac{-2}{1} =-2[/tex]

[tex]m=-2[/tex]

y=x+2

Step-by-step explanation:

Slope intercept:

y=mx+b

Two points: (1,3) and (5,7)

7-3/5-1 is 4/4 or 1.

y=1(x)+b

y=x+b

Plug in 1,3

Answer:

Decimal = 0.6

Percentage = 60%

Step-by-step explanation:

Let's simplify the fraction.

[tex] \frac{120}{200} = \frac{60}{100} = 0.6[/tex]

Hence the Decimal is 0.6

To express 120/200 in percentage , we have to multiply the fraction with 100.

[tex] \frac{120}{200} \times 100 = \frac{120}{2} = 60\%[/tex]

Hence the percentage value is 60%

Answer:

y = 2x + 3

Step-by-step explanation:

y = 2x - 8   passes through ( 1,5 )

y = 2x + 3 is parallel to y = 2x - 8 because it has the same m( 2x)

and it also passes through ( 1, 5 )

you divide 95.40 by 12 which equals 7.95

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

12 months = 95.40

1 month = 7.95

The amount paid monthly is 7.95.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

12 ÷ 4 is an expression.

3x + 4x = 5 is an expression.

2x3 - 4 is an expression.

We have,

Ms. sikes paid a total of 95.40 for 12 months magazine subscription.

This means,

12 months = 95.40

Divide 12 on both sides.

1 month = 7.95

This means,

The monthly amount is 7.95

Thus,

12 months = 95.40

1 month = 7.95

Step one:

given data

simple intereest= $750

rate= 3%

time= 4years

The Principal P

Step two:

SI= PRT/100

750= P*3*4/100

750=12P/100

cross multiply we have

12P=750*100

divide both sides by 12

P=75000/12

Answer:

n= 3

Step-by-step explanation:

3 (4 + n) = n + 18

you take 3x4=12

then 3x3=9 then you add 12 and 9 which would be in the ( )

12+9 = 21

then if you replace n =3 on other side and add it to 18 answer is 21

therefore both sides would equal 21 so n=3

3(4+3)=3+18

21=21

Answer:

1.) 4x + 36 < 60

2.) The family must spend less than 6 hours in Millersville watching the movie.

Step-by-step explanation:

1.) In order to write an inequality to represent the situation, we need to consider all variables. The main resultant / dependent variable is the money spent. The independent variable is the time.

Let x = time  and y = money spent.

y = mx + b

Since the entrance fee for the movie is $36, we know that the b = 36. Since the rate of change is $4, you know that m = 4. Lastly, since the maximum amount of money the family has is $60, y = 60.

60 = 4x + 36

Finally, since the money spent must always be LESS THAN 60, 4x + 36 < 60

2.) Soling the Inequality:

Firstly, isolate the 4x by subtracting 36 from both sides.

4x + 36 -36 < 60 - 36

4x < 24

Next, divide both side by 4 in order to isolate x. Since 4 is positive, DO NOT flip the less than

4x/4 < 24/4

x < 6

Since x represents the time, time < 6 hours, meaning that the family must spend less than 6 hours in Millersville watching the movie.

Answer:

1. 60>4x+36

2.6>x

Step-by-step explanation:

60 is the total amount of money the family has to spend, they want to spend less than that so...

60 is greater than what they will spend (60>)

the (x) is the amount of hours the family will spend at the city. parking cost 4 so that means 4 dollars per hour.

the 36 is what they have to initially spend to watch the movie

if you subtract both sides of the (>) by 36 you get

24>4x

then you divide both sides by 4 to get the (x) by itself, which gets you

6>x

meaning that the amount of hours the family will spend at the city will have to be 5 hours

correct me if I'm wrong but i believe that this is the correct answer... i double checked

The amount of investment in worth in 3 years is $74.21

Compound interest, also known as interest on principal and interest, is the practise of adding interest to the principal amount of a loan or deposit.

Given:

P =$55

R= 10.5%

T= 3 years

So, r = R/100

r = 10.5/100

r = 0.105 rate per year,

Then solve the equation for A

A = P[tex](1 + r/n)^{nt[/tex]

A = 55.00[tex](1 + 0.105/1)^{(1)(3)[/tex]

A = 55.00(1 + 0.105)³

A = $74.21

Hence, the investment amount is $74.21

Answer:

The equation that models this scenario

250 = 5a + 10b

Where:

The number of students tickets = a

The number of non student tickets =b

Step-by-step explanation:

A school club visits a science museum. Student tickets cost $5 each. Non-student tickets cost $10 each. The club paid $250 for the tickets. Which equation below could not model this situation?

Let us represent:

The number of students tickets as = a

The number of non student tickets as =b

Let the total cost be represented by = y

From the question

Student tickets cost $5 each. Non-student tickets cost $10 each. The club paid $250 for the tickets.

The equation that models this scenario

y = $5 × a + $10 × b

y = 5a + 10b

250 = 5a + 10b
