What is the slope of the line with equation 2x−5y=52?

Answers

Answer:

m = 2/5

Step-by-step explanation:

2x - 5y = 52

-5y = -2x + 52

y = 2/5x - 52/5

The slope of the line with equation 2x−5y=52 is 2/5.

The given equation of line is 2x−5y=52.

What is the slope of a equation?

The slope formula is used to calculate the inclination or steepness of a line. It finds application in determining the slope of any line by finding the ratio of the change in the y-axis to the change in the x-axis.

The given equation 2x−5y=52 can be rewritten as

2x-52=5y

⇒ y = 2x/5-52/5

Now, compare y = 2x/5-52/5 with the standard form of an equation y=mx+c

So, m=2/5

Therefore, the slope of the line with equation 2x−5y=52 is 2/5.

4. What are the last TWO DIGITS of 2^2017

a Explain how you found the last 2 digits of 2^2017

b. Show how you found the last 2 digits of 2^2017

Answers

Compute 2²⁰¹⁷ modulo 100.

From the given table,

2²² ≡ 2⁴² ≡ 2⁶² ≡ 4 (mod 100)

and we have

2017 = 32 • 62 + 33

62 = 1 • 42 + 20

Then

2²⁰¹⁷ ≡ (2⁶²)³² • 2³³ (mod 100)

2²⁰¹⁷ ≡ 4³² • 2³³ (mod 100)

2²⁰¹⁷ ≡ (2²)³² • 2³³ (mod 100)

2²⁰¹⁷ ≡ 2⁶⁴ • 2³³ (mod 100)

2²⁰¹⁷ ≡ 2⁶² • 2²² • 2¹³ (mod 100)

2²⁰¹⁷ ≡ 4² • 2¹³ (mod 100)

2²⁰¹⁷ ≡ (2²)² • 2¹³ (mod 100)

2²⁰¹⁷ ≡ 2⁴ • 2¹³ (mod 100)

2²⁰¹⁷ ≡ 2¹⁷ (mod 100)

and from the table, we get

2²⁰¹⁷ ≡ 2¹⁷ ≡ 72 (mod 100)

a family of four goes to a movie theatre and spends $26.50. they buy 2 tickets for adults, and 3 boxes of popcorn at $2.50 per box. what is the cost of one adult ticket

Answers

Answer:

$9.5

Step-by-step explanation:

3x2.50= 7.50

26.50-7.5 =19

19/2 = 9.5

9.5 for one adult ticket

Hi!

First, let's add (or multiply) the boxes of popcorn.

2.50 + 2.50 + 2.50 (or 2.50 x 3) is 7.50. so the popcorn all together is $7.50.

Next, we subtract the popcorn cost from the cost altogether.

26.50 - 7.50 = $19

Next, we divide the $19 by two.

19 ÷ 2 = 9.50

To make sure this is true, what we do is multiply 2 x 9.50.

2 x 9.50 = 19.

So 9.50 is your answer.

(NOTICE: your problem says a family of 4. you didn't give me the total for the other 2 people who were going to the movie, so this is just my estimate for just those 2 adults. If it's not correct, that is the reason why, otherwise, it is the answer.)

Hope this helps!

Assuming that blueberry blackberry combination pies aren’t a thing,

Then the answer is 9/10

This problem involves adding fractions with different denominators. For this type of problem you can change the value of the denominators in each fraction to equal the same thing. Since they are fractions, the overall value will not change if you multiply the numerator and denominator by the same number.

We add 1/2 of the blueberry and 2/5 of the blackberry this will give us 9/10.Firstly we found the LCM of their denominator which is 10,you divide the ten by the denominator of 1/2 which is 2 and multiply by the numerator which is 1,it will make 5 and we put the plus sign you repeat the same process with 2/5 which will give you 4.You then add 4+5 which will make 9 the numerator and 10 as the denominator.
