Basically it just means that you are trying to spend money that you don't have on things you don't need.

Step-by-step explanation:

Taken literally, you can live in a pretty small house and be content. You don;t need to spend tons of money to be happy. This can be a bad thing to do because you don't want to be in debt to anyone, especially when that could have been avoided.

[tex] \huge \boxed{ \boxed{ \sf \: \frac{1}{2} }}[/tex]

Step-by-step explanation:

let width be w

according to the question

the equation is

[tex] \sf \frac{9}{10 } \times w = \frac{9}{20} [/tex]

let's figure out the equation

what formula is applied, I mean what method

Answer:

B

Step-by-step explanation:

We have the equation:

[tex]x^2+10x+24=0[/tex]

We can factor:

[tex](x+6)(x+4)=0[/tex]

By the Zero Product Property:

[tex]x+6=0\text{ or } x+4=0[/tex]

Solve:

[tex]x=-6\text{ or } x=-4[/tex]

-4 is greater than -6, so -4 is the greater root.

Our answer is B.

Answer:

0.52014035087

Step-by-step explanation:

Answer:

0.51868439468

Step-by-step explanation:

Using the function concept, it is found that [tex]x^2 + y^2 = 100[/tex] is not a function, as for each value of x there is more than one corresponding value of y.

In this problem, the relation is:

[tex]x^2 + y^2 = 100[/tex]

For example, considering x = 0, the corresponding values of y are:

[tex]0^2 + y^2 = 100[/tex]

[tex]y = \pm \sqrt{100}[/tex]

[tex]y = \pm 10[/tex]

Hence, it is not a function, as for each value of x there is more than one corresponding value of y.

Answer:

t₃ = 3

Step-by-step explanation:

To find the third term substitute n = 3 into the formula, that is

t₃ = 3² - 2(3) = 9 - 6 = 3

Answer:

tn=n^2-2n

n =3

t3 = 3^2 -2(3)

t3 = 9-6

t3 = 3

Answer:

Artaud is 15 years old

Step-by-step explanation:

Imagine Artaud is x yearrs old.

Now, turning the words in the problem into math equations, we get:

-x + 42 = 27.

Solving for x, we get:

-x = -15

x = 15.

So, Artaud is 15 years old.

Answer:

h(x) = (x + 4)^2 - 2

Step-by-step explanation:

Start with the red graph:  f(x) = x^2

First we move the entire graph 4 units to the left.  The resultant function is g(x) = (x + 4)^2.

Next, we move this latest graph 2 units down.  The resultant function (and answer to this question) is h(x) = (x + 4)^2 - 2

Answer:

Single increase rate = 29.47%

Step-by-step explanation:

Given:

First increase rate = 7%

Second increase rate = 21%

Find:

Single increase rate

Computation:

Assume number is a

So,

First increase rate = 7%

a + 7%

= 1.07a

Second increase rate = 21%

1.07a + 21%

1.2947a

So,

Single increase rate = 1.2947 - 1

Single increase rate = 0.2947

Single increase rate = 29.47%

Answer:

Loss section

Step-by-step explanation:

Given

[tex]c = 20n + 500[/tex] -- cost

[tex]r = 25n[/tex] -- revenue

Required

Determine where n = 150 is

To do this, we substitute 150 for n in the given functions

[tex]c = 20n + 500[/tex]

[tex]c = 20 * 150 + 500[/tex]

[tex]c = 3500[/tex]

[tex]r = 25n[/tex]

[tex]r = 25 * 150[/tex]

[tex]r = 3750[/tex]

The above shows that the revenue is greater than cost for n = 150.

This implies that, n = 15o is the loss section.

Answer: profit section :)

The slope is -2.

The slope is the rise over the run. Because the line goes down from left to right, it makes the value negative. For every one the it moves to the right, the line goes down two units.

Answer:

x = 1; y = 2

Step-by-step explanation:

To find x:

Multiply (5x+y=7) by 3 to get the y's in both equation the same, and you will get 15x+3y=21.

Now the y's cancel out. Subtract the remaining equations: (15x=21) - (6x=12) and you get 9x = 9. Divide everything by 9 and you get x=1.

To find y:

You can substitute 1 for x in either equation. I will use (5x+y=7).

Substitute the 1 for x: 5(1)+y=7

Simplify: 5+y=7

Put like terms on the same side by subtracting 5 from both sides: y=2

Check:

6(1) + 3(2) = 12

6 + 6 = 12

12 = 12 - this is right

5(1) + (2) = 7

5 + 2 = 7

7 = 7 - this is right

Answer:

F

Step-by-step explanation:

2x+y = -4

put into slope-intercept form: y = -2x - 4

-3y = 2x+12

In slope-intercept form: y = -⅔x - 4

Both equations have a y-intercept of -4. There is only one graph where both lines pass through (0,-4).

The solution of the given system of equation is (0, -4). Therefore, option A is the correct answer.

The given system of equations are 2x+y=-4 and -3y=2x+12.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

The system of equations can be solved as follows:

Here, 2x+y=-4 ----------(1)

-3y=2x+12 ----------(2)

From equation(1), y=-4-2x

Now, put y=-4-2x in equation (2) and simplify

That is, -3(-4-2x)=2x+12

⇒ 12+6x=2x+12

⇒ 4x=0

⇒ x=0

Substitute x=0 in equation (2), we get

-3y=12

⇒ y=-4

The solution of the given system of equation is (0, -4). Therefore, option A is the correct answer.
