-4x = y + 3

y = -4x - 3​ => 4x = -y - 3

-4x = y + 3

4x = -y - 3

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

0 = 0 (always true)

All Real Numbers

Answer:

x = x, y = -3 - 4x

Step-by-step explanation:

Subtract y from both sides of the equation.

-4x - y = 3

y = -4x - 3

Add 4x to both sides of the equation.

-4x - y = 3

y + 4x = -3

-4x - y = 3

Reorder the polynomial.

Add the two equations together to eliminate y from the system.

 -4x - y = 3

+ 4x + y = -3

          0 = 0

Since 0 = 0, the equations intersect at an infinite number of points.

Infinite number of solutions.

Solve one of the equations for y.

y = -3 - 4x

The solution is the set of ordered pairs that make y = -3 - 4x true.

Point form: (x, -3 -4x)

Equation Form: x = x, y = -3 - 4x

good luck, i hope this helps :)

Answer:

172.7

Step-by-step explanation:

2590 divided by 15 = 172.6666667

7 is greater than five so the 6 gets rounded up which makes the answer 172.7!

2590 divided by 15 can be calculated by division operation and it will be equal to 172

Division is a mathematical operation, in which we distribute the number in equal parts, the number on the upper side is the total quantity and the number on the bottom side is equal parts of numbers which have to be distributed.

We denote division by '÷' this symbol.

To divide 2,590 by 15, we can think of it as breaking up 2,590 into 15 equal parts. Each of these parts will have a value of 172, since 2,590 divided by 15 is equal to 172.

In mathematical terms, division is the inverse operation of multiplication. When we divide 2,590 by 15, we are asking, "How many times does 10 fit into 2,590?" The answer is 50, so 2,590 divided by 15 is equal to 172.

So, in summary, 2,590 divided by 15 is equal to 172, and this means that 2,590 can be evenly divided into 15 parts, each of which has a value of 172.

Step-by-step explanation:

Answer:

V=80π/3 or V=83.78

Step-by-step explanation:

The volume is

V=πr^2h/3

r=4 (because the radius is half the diameter)

h=5

V=π16*5/3

V=80π/3

Answer:

83.73

Step-by-step explanation:

volume = (1/3) · π · r2 · h

volume = (1/3) x 3.14 x 4^2 x 5

volume = (1/3) x 3.14 x 16 x 5

3.14 x 16 x 5 = 251.2

-x*3x*2x=6x^3

-6x^3<900

-(cube root both sides)

-6x<9.654893846

-divide by 6

-x=1.609148974

And since 1.609148974 is less than 5, that means that X<5 is correct and hence proved

For given cuboid, x < 5

"It is a three-dimensional geometric structure that has six rectangular faces, twelve edges and eight vertices."

V = l × w × h

where, l: length of the cuboid

w: width of the cuboid

h: height of the cuboid

For given example,

We have been given the total volume of the cuboid is less than 900 cm^3

⇒ V < 900 cm³

the length of the cuboid (l) = 3x

the width of the cuboid (w) = 2x

the height of the cuboid (h) = x

Using the formula of the volume of the cuboid,

⇒ V < 900

⇒ l × w × h < 900

⇒ (3x) × (2x) × (x) < 900

⇒ 6x³ < 900

⇒ x³ < 150

⇒ x < 5.3

⇒ x < 5

Therefore, for given cuboid, x < 5

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

Answer: 2⁵

Explanation: Since these two powers have the same base of 2,

you can multiply them together by simply adding their exponents.

When we do that, we get 2⁵.

A common mistake in this problem would be to multiply

the bases together and give an answer of 4⁵.

The 2's can't be multiplied together however because

they are  not coefficients, they are bases.

When applying your exponent rules, your base will never change.

Step-by-step explanation:

20% of $1200 is:

Since you saved $200 and its less than $240 you didn't reach your goal

Hi there!

No:

200 is only 6 parts of 1200 together which means that it can’t be 20% of 1200.

If it was 20% of 1200, it would then be 240 since 240·5=1200...

No, did not reach the goal since 20% of 1,200 is 240 and 200 is only 16.67% of $1,200.

Answer:

1. x³y² + 4x²y³ + 7y⁴ + x⁴

2. a² + b² + c² + 2ab + 2bc + 3ca

Step-by-step explanation:

1. x³y² + x²y³ + 3y⁴ and x⁴ + 3x²y³ + 4y⁴

= x³y² + x²y³ + 3y⁴ + x⁴ + 3x²y³ + 4y⁴

= x³y² + x²y³ + 3x²y³ + 3y⁴ + 4y⁴ + x⁴

= x³y² + 4x²y³ + 7y⁴ + x⁴

2. a² + 3ab - bc, b² + 3bc - ca and c² + 3ca - ab

= a² + 3ab - bc + (b² + 3bc - ca) + (c² + 3ca - ab)

= a² + 3ab - bc + b² + 3bc - ca + c² + 3ca - ab

= a² + b² + c² + 3ab - ab + 3bc - bc + 3ca - ca

= a² + b² + c² + 2ab + 2bc + 3ca

Step-by-step explanation:

p(x) = 15x-(2000+4x)

profit is going to be the difference between how much money you get from sales less the cost to make the items

the money you make in this case is $15 times the number of cds you sell, we will call the number of cds x

so 15x is the money from sales

the costs you have are 2000 to create the master and then $4 for every cd you create, so your costs will be 2000+4x

so profit is sales minus costs, therefore we get

p(x) = 15x - (2000+4x)

now to find specifically the profit when we create and sell 2800 cds, x = 2800, so we substitute that value in for x

p(2800) = 15(2800) - (2000+4(2800))

= 42000 - (2000+11200)

= 42000 - 13200

= 28800

The profit of selling 2800 additional DVDs is 28800 dollars.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, The profit function is P, and let no. of DVDs sold is x and the profit on each additional disc is,

= $(15 - 4).

= $11.

∴ The profit function p is,

P = 11x - 2000.

So, the profit by selling 2800 additional discs is,

P = 11(2800) - 2000.

P = 30800 - 2000.

P = 28800 dollars.
