Subtract the following polynomials vertically. (8x+5y+4)-(3x-9y-5)

Answer:

a>6

Step-by-step explanation:

Answer:

Step-by-step explanation:

-8 > 4 +2v ; subtract 4 from both sides

-8-4 > 4-4 +2v; calculate

-12 > 2v; divide both sides by 2

-6 > v

TO Know:

apply the same operation to both sides of inequality

if the operation is dividing or multiplying by a negative number change the direction of the inequality

Answer:

when you have Bob anything is possible

Answer:

They intersect

Step-by-step explanation:

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.

Here we have two functions:

1) y = 4x + 2

2) 8x + 2y = - 3

   2y = - 8x - 3

   // divide both sides by 2

   y = - 4x - 1,5  

- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.

Answer:

$100

Step-by-step explanation:

you have eight bowls so you divide 160 by 8 and you get 20 so each bowl is 20 so 5x20=100

Answer:

100

Step-by-step explanation:

First, calulate the cost of each bowl, so, 160/8=20

Next, calculate how much total it costs, so 20x5, which the answer is $100

Answer:

x = 51

Step-by-step explanation:

x = 180 - (2x - 8) - (180 - 153)

x = 180 - 2x + 8 - 27

3x = 180 - 27

3x = 153

x = 51

Answer:

80.5

Step-by-step explanation:

2x-8 + x =153

Answer:

One bottle of soap will hold 3/8

Step-by-step explanation:

3/4= The amount of soap she has in total

3/4= 6/8 which is the same amount but now we can divide it by 2

.75 (6/8) divided by 2= .375 (3/8)

So each soap dispenser will have 3.75 liters of soap.

Sentences: To check our work

.375x2= .75

3/4 divided by 2= 3.75

Answer:

280

Step-by-step explanation:

160 divided by 4 is 40 then times that by 7 and u get 280

Answer:

280 miles

Step-by-step explanation:

First you have to find how many miles a car travels in 1 hour. (160 ÷ 4 = 40).

Then, once you find that, you multiply 40 by 7. (280)

f(x)/g(x)

(x2-1)/(x-1)

x cannot equal 1 because this would render the denominator, also known as the divisor, as zero.

x can be greater than 1.

If you would like, we can factor the numerator...

x2-1

(x+1)(x-1)

FIRST...(x)(x)=x2

OUTER...(x)(-1)=-1x=-x

INNER...(1)(x)=1x=x

LAST...(1)(-1)=-1

x2-x+x-1

x2-1

So...

f(x)/g(x)=[(x+1)(x-1)]/(x-1)

(x-1) is in the numerator and denominator.  It cancels...

f(x)/g(x)=(x+1)

Answer:

Part A: S^2= 3V/H

Part B: S =[tex]\sqrt{3\frac{v}{h} }[/tex]

Part C: s=√3* 2,433,400 /138=230 metres

Part D: This website says that the length of Khufu's Pyramid is about 230 meters. My calculation was correct.  

Part E: S = √3*2,115,072/ 136 =216 metres

Part F: The length of Khafre's pyramid is about 215.5  My calculation was a little off, but not by much.

Part G: 14 meters longer

Step-by-step explanation:

Part A:

I am going to solve:

So,

V=1/3 [tex]HS^{2}[/tex]

Then, multiply both sides by 3:

V x 3= 1/3 [tex]HS^{2}[/tex] x 3

So,

3V=[tex]HS^{2}[/tex]

Then, we divide by H:

[tex]\frac{3V}{H}[/tex]=[tex]\frac{HSs^{2} }{H}[/tex]

So,

[tex]\frac{3V}{H}[/tex]= [tex]s^{2}[/tex]

Then switch sides:

[tex]s^{2}[/tex]= [tex]\frac{3V}{H}[/tex]

I hope this helps!

Answer: x = pi

sin²x - 2cos x - 2 = 0

⇔ 1 - cos²x - 2cos x - 2 = 0

⇔ cos²x + 2cos x + 1 = 0

⇔ (cos x + 1)² = 0

⇒ cos x + 1 = 0

⇔ cos x = -1

⇒ x = pi + k2pi

because 0 ≤ x < 2pi

=> x = pi

To find the amount of total students, you would do this:

[tex]15+16=31[/tex]

Since there are [tex]15[/tex] girls, the [tex]girls[/tex] to [tex]total students[/tex] ratio would be [tex]15:31[/tex].

Answer:

[tex]y= 10+12.5x[/tex]

Step-by-step explanation:

Given data

He paid $10 for parking and

$12.50 per ticket.

let the number of tickets be x

and let the total cost be y

Hence the expression in terms of x and y is

[tex]y= 10+12.5x[/tex]

Step-by-step explanation:

When a number  divides into another number without a remainder, it s called a factor of that number.  Lets say we want to  find the common factors of two numbers, we get the  factors of each one and  compare them. The common factor is the one that is found in both lists

While The Highest common factor, is the highest factor number found in both lists.

b) 2b , 3b

Factors of 2b= 1, 2 and b

Factors of 3b=1, 3 and b

Common factors =1 and  b

HCF=1b

e) 5bc, 2c2, 3cd

Factors of 5bc=  1, 5, b, c

Factors of 2c2= 1,  2, c, c2

Factors of  3cd= 1, 3, c, d

Common factors = 1 and c

HCF= 1c

f) 4a2b, 8b2c, 6bcd

Factors of 4a2b=  1, 2, 4, a, a2, b

Factors of 8b2c= 1, 2, 4, 8, b, b2, c

Factors of  6bcd= 1, 2,3,6, b, c,d

Common factors = 1, 2 , b

HCF=  2b
