It was the day before the big U.S. History test. It was an open-note exam, so if students took good notes, they would probably get a good grade on it. The problem for Helga was that she waited until the last minute to review her notes—and they were terrible. In a panic, she called her best friend, Tracy, and asked her to make a copy of the notes she took so Helga could use the copy to take the test. Tracy always took detailed notes, and Helga knew she would get a good grade if she used the copy of Tracy’s notes. Why is this most likely a dangerous situation for both Helga and Tracy? They would put their education at risk. They would break their parents’ rules. They would put their friendship at risk. They would break the school laws.

Use one of the points, substitute into equation and solve for r:

Answer:

2x²-3x-5

=2x²-3x-5

=2x²-5x+2x-5

=2x(x-5)+2(x-5)

=(x-5)(2x+2)

Answer:

(x + 1)(2x - 5)

Step-by-step explanation:

Assuming you require the expression factorised.

2x² - 3x - 5

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 5 = - 10 and sum = - 3

The factors are + 2 and - 5

Use these factors to split the x- term

2x² + 2x - 5x - 5 ( factor the first/second and third/fourth terms )

= 2x(x + 1) - 5(x + 1) ← factor out (x + 1) from each term

= (x + 1)(2x - 5) ← in factored form

Answer:87.5%

Step-by-step explanation:

Given

Henry received [tex]\frac{7}{8}[/tex] of the votes in the election

i.e. 7 parts of votes are in favor of Henry out of 8

In terms of percentage, it is  given by

[tex]\Rightarrow \dfrac{7}{8}\times 100=87.5\%[/tex]

5x^2-11x-2x^3+6

Simplify the expression

answer:  = -2x^2+6x+4

Answer:

Step-by-step explanation:

Equation

2x + 2 + 3x - 1 + x +4 = 29             Collect like terms on the left

6x + 5 = 29                                     Subtract 5 from both sides

6x = 29 - 5

6x = 24                                            Divide by 6

x = 24/6

x = 4

Length of the Sides.

2x + 2 = 2*4+2 = 10

3x - 1 = 3*4 - 1 = 12 - 1 = 11

x + 4 = 4 + 4 = 8

Step-by-step explanation:

Answer:

The part of the expression that represents the number of quarters is;

D. 25·(3·x + 1)

Step-by-step explanation:

From the question, we have;

The values of the coins Luis has = Nickels, Dimes and quarters

The expression that represents the value of all the coins in cents is given as follows;

5(x + 2) + 10·1 + 25·(3·x + 1)

The value of a nickel = 5 cents

The value of a dime = 10 cents

The value of a quarter = 25 cents

Therefore, the part of the expression representing the number of quarters Luis has, has 25 as a factor

Therefore, the part of the expression that represents the number of quarters = 25·(3·x + 1).

Answer:

2/3xy.

Step-by-step explanation:

8x/12x^2y

The 8 and 12 simplify to 2/3 and x and x^2 simplify to 1/x so we have:

= 2/3xy.

Answer:

Step-by-step explanation:

3x - 3y = 3(x-y)

Answer:

x = -3 and x = 1

Step-by-step explanation:

first, square each side

12 - 8x = x² - 6x + 9

x² + 2x - 3 = 0

(x - 1)(x + 3) = 0

x = -3

x = 1

Answer:

Part a) 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week, how many seconds are in a week

60x60=3600 x 24= 86400 x 7= 604800

So 604,800 seconds in a week

Part b) James and Kelly have $10 to spend at a grocery store. If they get 3 avocados which cost $1 each, 4 tomatoes which cost a total of $2 for all 4, and two loaves of bread which cost $2 each, how much change will James and Kelly receive after their purchase?

So 3 x 1= $3

+ $2

2 x 2= $4

3+2+4= $9

10-9= $1

So they'll get back $1

Answer:

A. x =2

Step-by-step explanation: Rearrange terms 3x - 8 = 6 ( 1 - 2x ) + 16 ---> 3x - 8 = 6 ( -2x + 1 ) +16

Distribute

Add the numbers

Add 8 to both sides of the equation

Simplify

Add 12x to both sides of the equation

Simplify

Divide both sides of the equation by the same term

Simplify -------> x=2

Answer:

The correct answer is A: 4/5

Step-by-step explanation:

We would divide 24/30 and get 4/5

Step-by-step explanation:

m= 1-4/4-8 = -3/-4 = 3/4

y-1 = 3/4(x - 4)

y-1 = 3/4x -3

y = 3/4x -2

Answer:

I) 616

II) 4.53

Step-by-step explanation:

For the first one, just plug in 7 as R.

A = 4 x (22/7) x 7^2

A = 12.57142857 x 49

A = 616

For the second, one, put 452 4/7 as A.

452 4/7 also is 258.285

258.285 = 4 x (22/7) x r^2

258.285 = 12.57142857 x r^2

Divide both sides by 12.57142857

20.55372408 = r^2

Square root 20.55372408 for R.

4.533621519 = R

OR

4.53 = R
