The product of two positive consecutive integers is 24 more than 6 times the first number.
What is the product of the two integers?

Answers

Answer:

The product of two integers is 72.

Step-by-step explanation:

Let,

x and x+1 be the two consecutive positive integers.

According to given statement;

The product of two positive consecutive integers is 24 more than 6 times the first number.

x(x+1) = 6x+24

[tex]x^2+x=6x+24\\x^2+x-6x-24=0\\x^2-5x-24=0\\x^2-8x+3x-24=0\\x(x-8)+3(x-8)=0\\(x-8)(x+3)=0\\[/tex]

Either,

x-8 = 0

x=8

Or,

x+3 = 0

x=-3

As the integer is positive, therefore, the two integers are 8 and 9.

Product of two integers = 8*9 = 72

Hence,

The product of two integers is 72.

Answers

Answer:

8.5 hours

Step-by-step explanation:

30 mins per page ( 15 )

so, 30 × 15 = 450

each hour is 60 minutes so 450 ÷ 60 = 7.5

then add the 1 hour that she already took to write the outline, so 8.5 hrs

Answer: y=mx+b = y=30(15)+1

Explanation: the slope is 30 because that's how many minutes it will take her to write each page and x will be the amount of pages she is doing as b is the 1 hour she spent doing her outline. (Hope this helped if I'm incorrect I'm so sorry, I'm tired)

Slope of covalent bond (RED) =

Answers

Answer: 10

Step by Step Solution:
You have x and y as your axis’s and that as your table with x being time and y being percent bounded. As for that you got (0, 0) and (5, 50).

Then you plug those numbers into the equation to finding slope: m = y2 - y1 / x2 - x1 to have m = 50 - 0 / 5 - 0

Then you have to simply the equation to have m = 50 / 5 and then you divide them as the line of a fractions means division and you will have m = 10

Delaney used the equation 14x = 28 to model her scenario, where x represents the amount of money she has left.
After solving her equation, Delaney says the solution, x = 2, means that she has $2.00 left. Is she CORRECT? Why or why

No, this means she has 2 times 14 total. if she does 28/2 she will get 14. she has $14 left.

Find the coordinates of the midpoint of LB if L(8,5) and B(-6,2)

10 points!!!

Answers

Answer:

A, (1, 3+1/2)

Step-by-step explanation:

Midpoint formula for reference: m= {(x1 + x2)/2, (y1 + y2)/2}

Plugging in the points we get: m= {(8 - 6)/2, (5 + 2)/2}

Now we simplify using PEMDAS. First step is parentheses.

m= {2/2, 7/2}

Simplifying again (and making 7/2 a mixed number), it becomes

m= {1, 3+1/2}

Hope this helps!

When N divided by 5 leaves a remainder of 2, find the one's digit of N

Answers

Step-by-step explanation:

One's digit of N can be 2 or 7.

Answer:

Step-by-step explanation:

If the number ends in 0 or 5 those are the only two results that 5 will divide into a number evenly.

For example 105/5 = 21

And example 1020/5 = 204

So if you want a  remainder of 2, there are 2 ways to get it.

1) If the number ends in a two, you will get a remainder of 2. That's because 0 + 2 will give 2.

For example 252 / 5 = 50 with a remainder of 2

2) The other way is if the end number is 7.

3347 / 5 = 669 with a remainder of 2.

The reason this works is if you subtract 2 from the number given then the units digit will be either 0 or 5. Those two endings result in even division.
