What is the slope of the line through(-5, -10) and(-1, 5)?

Answers

Answer:

15/4

Step-by-step explanation:

to find the slope with two coordinates use

y2 - y1 / x2 - x1

first find the difference between the ys

the 2nd y point is 5, and the 1st y point is -10, so subtract them from each other

5 - (-10) = 5 + 10 = 15

then find the difference between the xs

the 2nd x point is -1, and the 1st x point is -5, so subtract them from each other

-1 - (-5) = -1 + 5 = 4

now put the difference in ys over the difference in xs

15 / 4

So thats your slope

You're shopping for a guitar and find one
with an original price of $160. The store is
offering a 30% discount on all guitars. Wait!
There is an additional 25% off all purchases.
What is the sale price of the guitar?

Answers

$84

$160 * 0.30 = $48

$160 - $48 = $112

$112. * 0.25 = $28

$112 - $28 = $84

Use what you know.
Guitar cost =$160 w/ 30% off
30% = 30/100 = 0.30.

30% off means 30% of the price $160 will be taken off so that is why I multiplied 160 by 0.30 (30/100).

30% of 160 is 48 so I subtracted 48 from 160 which equals $112.

With an extra 25% off I repeated the same steps above.

25/100 = 0.25

$112 * 0.25= $28
$112 - $28 = $84

If y = 3x^4 -2x^3-7x+5, find dy/dx.

Answers

Dy/dx = 12x^3 - 6x^2 - 7

The derivative of [tex]y = 3x^4 - 2x^3 - 7x + 5[/tex] with respect to x is

dy/dx = 12x³ - 6x² - 7.

We have,

The power rule states that if we have a term of form a[tex]x^n[/tex], the derivative with respect to x is given by [tex]d/dx(ax^n) = nax^{n-1}.[/tex]

Applying the power rule, we differentiate each term as follows:

[tex]d/dx(3x^4) = 3 \times 4x^{4-1} = 12x^3\\d/dx(-2x^3) = -2 \times 3x^{3-1} = -6x^2\\d/dx(-7x) = -7 \times 1x^{1-1} = -7[/tex]

d/dx (5) = 0 (since 5 is a constant)

Combining these derivatives, we get:

dy/dx = 12x³ - 6x² - 7

Therefore,

The derivative of [tex]y = 3x^4 - 2x^3 - 7x + 5[/tex] with respect to x is

dy/dx = 12x³ - 6x² - 7.

Paulina has read 58 pages of the 234-page book she is doing a book report on for Language Arts. She plans to finish her book by reading 25 pages each day. Using d for the number of days, write a two-step equation to model this situation that you could solve to find out how many days Paulina took to read the rest of her book. Multiple choice question.
A) 25d – 58 = 234
B) 25d + 58d = 234
C) 25 + 58d = 234
D) 25d + 58 = 234

Answers

The answer is d) 25d + 58= 234

Answer:

D

Step-by-step explanation:

A:

25d - 58 = 234

Add 58 to 58 and 234

25d = 292

Divide 25 from both sides

d = 11

A is incorrect because you need to subtract the pages that have been read.

B:

25d + 58d = 234

Combine Like Terms

83d = 234

Divide 83 from both sides

d = 83

B is incorrect because 58 pages aren't days, those are the pages read so this equation is overall incorrect.

C:

25 + 58d = 234

Subtract 25 from both sides

58d = 209

Divide both sides by 58

d = 3.603 and so on

C is incorrect because, again, 58 isn't the days its the pages read.

D:

25d + 58 = 234

Subtract 58 from 58 and 234

25d = 176

Divide 25 from both sides

d = 7.04

D is the correct answer because 25 is the days and 58 is the pages read. You subtracted 58 from each side, making the number of pages in the book go down because you read those pages. You also divided 176 (the pages left) by the days, so 7.04 is your answer. 7 is the answer rounded down. D is your answer.

a) solve x + x + x = 54
b) solve y/5 = 7
c) solve 4t+6=24​

Answers

Answer:

a) x = 18

b) y = 35

c) t = 4.5

Step-by-step explanation:

a) x + x + x = 54

3x = 54

x = 54 ÷ 3

x = 18

b) y/5 = 7

(y/5) × 5 = 7 × 5

y = 35

c) 4t + 6 = 24

4t +6 - 6 = 24 -6

4t = 18

4t ÷ 4 = 18 ÷ 4

t = 4.5

Answer:

a) 18

b) 35

c) -4.5

Step-by-step explanation:

a) x + x + x = 54

combine like terms.

3x = 54

Divide both sides by 3.

x = 18

b) y / 5 = 7

Multiply both sides by 5.

y = 5 × 7

y = 35

c) 4t + 6 = 24

Take 6 to right side.

4t = 24 - 6

4t =  -18

Divide both sides by 4.

t =  -4.5

Answer:

y = (1/2)x - 1

Step-by-step explanation:

We can find the slope using the equation (y2-y1)/(x2-x1)

(-2- (-3))/6-4 = 1/2

The slope is 1/2 and the equation as of now is y = (1/2)x + C.

Now we can plug in any of the given data to find C in the equation.

-3 = 1/2(4) + C

-1 = C

C = -1

We now plug in -1 for C and get y = (1/2)x - 1 as our answer.

Between what two consecutive integers does log ₂ 75 lie?

Answers

Answer: The two consecutive numbers are 6 and 7.

Step-by-step explanation:

Here the problem is that the logarithm is not the natural logarithm we usually use, to return to the natural logarithm, we can use the next property:

Logₐ(x) = Ln(x)/Ln(a)

Then:

Log₂(75) = Ln(75)/Ln(2)

Now we can do these calculations.

Ln(75)/Ln(2) = 4.317/0.693 = 6.229

Now we want to find two consecutive integers, n and m, such that:

n < 6.229 < m

Because they are consecutive numbers, we must have:

m = n + 1

then:

n < 6.229 < n + 1

The only possibility here is:

n = 6

n + 1 = 7

The two consecutive numbers are 6 and 7.
