Answer:

(0,-1)

(1,-5)

(2,-9)

Step-by-step explanation:

y = −4x −1

Let x=0

y = 0-1 = -1  (0,-1)

Let x = 1

y = -4(1) -1 = -4-1 =-5  (1,-5)

Let x = 2

y = -4(2) -1 = -8-1 =-9 (2,-9)

Answer:

CSA is 12.57

TSA is 18.85 .. i dont know what the question is asking..

I will recommend you to use TSA

Answer:

19ft

Step-by-step explanation:

Formula for surface area of the cylinder=2πr(r+h)

We have,

h=2ft

d=2ft

r=d/2=2/2=1ft

Now,

2πr(r+h)=2π*1(1+2)=2π*1*3=6π=18.8495559215

Rounding to the nearest tenth,

We get Surface area of the cylinder=19 ft

Answer:

see below

Step-by-step explanation:

b - 4 = 3

Add 4 to each side

b - 4+4 = 3+4

b = 7

-32 = 8w

Divide by 8

-32/8 = 8w/8

-4 = w

n/7 = -4

Multiply by 7 to each side

n/7 *7 = -4*7

n = -28

Step-by-step explanation:

8-1-(18-2)÷8

PEMDAS says parentheses first

8-1-16÷8

Then divide

8-1-2

Then subtract from left to right

7-2

5

you take the derivative of x and y, and then divide them to find the instantaneous slope.

Answer:

[tex]-73[/tex]

Step-by-step explanation:

Note: My explanation is based of the order-of-operations

First, using the order-of-operations, we evaluate the expressions in parentheses. Fully simplifying [tex](5-7)^2[/tex] gives us: [tex](5-7)^2 = -2^2 = 4[/tex].

Next, we do [tex]6\cdot2[/tex] giving us [tex]12[/tex]. So far, our expression is simplified to [tex]\frac{84}{12} + 4 - 72 - 12[/tex].

We also know that [tex]\frac{84}{12}[/tex] is just [tex]7[/tex] so we can replace that value in the expression leaving us with: [tex]7+4-72-12[/tex]. Now, we can solve it in simple steps!

1)  [tex]7+4=11[/tex]

3) [tex]11-72=-61[/tex]

4) [tex]-61-12=-73[/tex]

Our answer is [tex]-73[/tex]

Hopefully this helped you out! Please (please) tell me if their is a mistake in the solution and I will correct it as fast as possible for me.

Answer:

35n - 63

Step-by-step explanation:

The area of a rectangle is given by

A = l*w where l is the length and w is the width

A = 7(5n-9)

Distribute

A = 35n - 63

Area of rectangle = Length * Width

Length is 5n-9

Width is 7

⇛Area = 5n-9(7)

⇛Area = 33n - 63

Answer:

Step-by-step explanation:

I am assuming 1 and 2 are asking for factors,

I am only gonna solve 4 for the sake of time,

9x^5-x^3+2x^2-x

x(9x^4-x^2+2x-1)

x(9x^4-(x^2-2x+1)

x(9x^4-(x-1)^2)

x(3x^2+x-1)(3x^2-x+1)

x^4+2x^2-24

x^4+6x^2-4x^2-24

x^2(x^2+6)-4(x^2+6)

(x^2-4)(x^2+6)

(x+2)(x-2)(x^2+6)

a^4+a^2+1

a^4+1+a^2

(a^2+1)^2-2a^2+a^2

(a^2+1)^2-a^2

(a^2+1-a)(a^2+1+a)

(a^2+a+1)(a^2-a+1)

a^3+b^3+c^3-3abc

=(a+b)^3+c^3−3ab(a+b)−3abc

=(a+b+c)^3−(3c(a+b)^2+3(a+b)c^2)−3ab(a+b+c)

=(a+b+c)^3−3c(a+b)(a+b+c)−3ab(a+b+c)

=(a+b+c)^3−(a+b+c)(3ab+3bc+3ac)

=(a+b+c)(a^2+b^2+c^2+2ab+2bc+2ac)−(a+b+c)(3ab+3bc+3ac)

=(a+b+c)(a^2+b^2+c^2−ab−bc−ac)

Answer:

I think B is correct

Step-by-step explanation:

Because it it shows that -4 is going lesser direction including-4 .

Answer:

Equation A is true; Equation B is not

Step-by-step explanation:

There is a standard formula for the "difference of cubes" that is:

x^3 - y^3 = (x - y)(x^2 + xy + y^2)

and this perfectly matches equation A.

Equation B has the square of n (n^2) on the left side but not on the right side.  Thus this is not an identity.

Answer:

hes going 10 miles an hour,

Step-by-step explanation:

if it took you 3.5 hrs and you went 35 miles, you can do 35/3.5=10, which is 10 miles an hour

Answer:

10 miles per hour

Step-by-step explanation:

We know that distance = rate * time

35 miles = rate * 3.5 hours

Divide each side by 3.5 hours

35 miles / 3.5 hours = rate

10 miles per hour = rate

Answer:

58°

Step-by-step explanation:

360-(148+90) =122

180-122 = 58

Answer:

answer is 122 degrees because X is outside the fig.

Answer:

4 = -8 - x

4 + 8 = -8 + 8 -x

12 = -x

x = -12

So, -12 is the answer.

Answer:

y = 6/5x - 2

Step-by-step explanation:

First we need to put the equation given in slope intercept form, y = mx + b

6x - 5y = 5

Solve for y

6x - 5y = 5

Subtract 6x from both sides

-5y = -6x + 5

Divide both sides by -5

y = 6/5x - 1

Now we have the equation in slope intercept form

y = 6/5x - 1

We want to find the equation that would be parallel to it

Parallel lines have the same slope

The equation y = 6/5x - 1 has a slope of 6/5 so an equation that is parallel to it would also have a slope of 6/5

The only equation that has a slope of 6/5 is the top left one therefore that is the answer

Answer:

y = 6/5x - 2

Step-by-step explanation:

Simplify the given equation:

[tex]6x-5y=5\\-5y=-6x+5\\y=\frac{6}{5}x-1[/tex]

In order for another equation to be parallel, it must have the same slope. Therefore, y = 6/5x - 2 is the correct answer.

Bags of limes = 4

Total limes in each bag = m

Total limes = 4m

ATQ

4m - 7(4)= 16

4m = 16+28

4m = 44

m = 44/4

m = 11

Value of m = 11

Problem 22

You have the correct answer since there are 9 non-white socks out of 15 total.

========================================================

Problem 23

------------------------

Explanation:

We have 10 blue marbles and 10+4+5+6 = 14+11 = 25 marbles total

This means there are 25-10 = 15 non-blue marbles.

The probability of selecting a non-blue marble is 15/25. I won't reduce this as we'll use this fraction to set up the next probability.

Because the marble is not replaced, this means we go from 15 non-blue marbles to 15-1 = 14 non-blue marbles. We also go from 25 total marbles to 25-1 = 24 total.

In short, the fraction 15/25 turns into 14/24 after subtracting 1 from each part.

--------------

Let's reduce each fraction mentioned

15/25 = (3*5)/(5*5) = 3/5

14/24 = (2*7)/(2*12) = 7/12

Then we'll multiply the two reduced fractions

(3/5)*(7/12) = (3*7)/(5*12) = 21/60

Lastly, we'll reduce that result

21/60 = (3*7)/(3*20) = 7/20

The probability of selecting two marbles that aren't blue is 7/20. This is done without replacement.

--------------

As a shortcut, we could say:

(15/25)*(14/24) = 7/20

Answer:

+ (+9) = -9  

Step-by-step explanation:

- (-9) = 9 A negative times a negative is a positive

- (+9) = -9   A negative times a positive is a negative

+ (-9) = -9  A positive times a negative is a negative

+ (+9) = -9 A positive time a positive is a positive

Answer:

Square

Step-by-step explanation:

It got 4 sides like square and its form is looking like a square.

Answer:

[tex]\displaystyle 4[/tex]

Explanation:

[tex]\displaystyle y = 3sin\:(\frac{\pi}{2}x + \frac{\pi}{2}) \\ y = 3cos\:\frac{\pi}{2}x[/tex]

[tex]\displaystyle y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi[/tex]

OR

[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi[/tex]

You will need the above information to help you interpret the graph. So, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph hits [tex]\displaystyle [-5, 0],[/tex] from there to [tex]\displaystyle [-1, 0],[/tex] they are obviously [tex]\displaystyle 4\:units[/tex] apart, telling you that the period of the graph is [tex]\displaystyle 4.[/tex] Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 0,[/tex] in which each crest is extended three units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
