Answer: (x+3) (x-3)  im pretty sure!

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.

Answer:

4 2 8 89 8

Step-by-step explanation:

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.

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.

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.

Answer:

y=2

Step-by-step explanation:

horizontal lines are y= the y intercept

if you want the line to go through the point (-2,2) it would be y=2 because points are written as (x,y)

the line y=2 would cross through the y access at 2 and also cross through every other point that is (x,2)

Answer:

A. Vaccinations give you a small dose of a virus

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:

Angle a=45, Angle b=45

Step-by-step explanation:

The angles are complementary angles which means they both add up to 90 degrees.  And if angles a and b are equal then its 90/2 which is 45.

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

Answer:

Value is 15 and measure is 151
