What's the value of x? (Hint: it's not 7) and please explain

the 14 cars sold = 56% of total car stock

how many cars (noted n) for 100 % ?

14.............56%

n..............100%

n x 56% = 14 x 100%

n = 14 : 0,56

n = 25

total cars in stock : 25

56% were sold

so 25 x 56% = 14 have been sold

Answer:

above is the solution to the question

Answer:

288

you first have to figure ot what

does 20% means. And this

questions is with subtracting.

So,

20% = 72

And since the question is with

subtracting we use our 360$

from before and we subtract.

360$ - 20% = 288 or

360$ - 72 = 288

I hope that explanation helped

you understand why the answer

is 288.

The answer is nine .nine is not a perfect square.

Answer:

  4200

Step-by-step explanation:

The least common multiple (LCM) is the product of the unique factors of the numbers:

  600 = 4 × 150

  1050 = 7 × 150

LCM(600, 1050) = 4×150×7 = 4200

_____

The above factoring may also help you see that the LCM is also the product divided by the greatest common factor:

  LCM(600, 1050) = 600 × 1050 / GCF(600, 1050)

  = 600 × 1050 / 150

  = 4200

Answer: C. rationalizing the denominator

Rationalizing the denominator is a useful step to simplify expressions where there are square roots in the denominator. It doesn't apply to actually solving a quadratic. On the other hand, the quadratic formula can solve quadratics. The same applies for choices B and D as well.

Withoutbaltering her variable expenses is $224 extra could she possibly put towards her credit cards.

The “ pie chart” is also known as a “circle chart”, dividing the circular statistical graphic into sectors or sections to illustrate the numericical value.

Given

Monica is trying to lower her credit card debt and has been tracking her expenses for the past month.

She identified her variable expenses in relation to her fixed expenses.

According to the pie chart, 36% and 56% are used for expenses, so there is 8% left over.

Multiply her monthly income by 8%:

2800 x  0.08 = 224

Hence, withoutbaltering her variable expenses is $224 extra could she possibly put towards her credit cards.

Answer:

[tex]y=\frac{3}{50} (x-3)^{2}+2[/tex]

Step-by-step explanation:

Vertex: (3,2)

Point: (13,8)

The equation form is [tex]y=a(x-h)^2+k[/tex]

h = 3

k = 2

y = 8

x = 13

Plug in the values into the form..

[tex]8=a(13-3)^{2} +2[/tex]

Simplify and solve for a..

[tex]8=a(10)^{2}+2[/tex]

[tex]8=100a+2[/tex]

[tex]100a=8-2[/tex]

[tex]100a=6[/tex]

I think this is the answer!

c=3/d

The formula for c in terms of d is c= 3/d

The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional. When y and x are two values that are directly proportional to one another, the proportionality constant k is defined as k=y/x.

Given:

c=0.5 when d=6

We know that c is inversely proportional to d.

c ∝ 1/d

c = k / d

and, k = cd

k = 0.5 x 6

k = 3

Hence, the formula for c in terms of d is c= 3/d

Step-by-step explanation:

Well i dont know how to explain but it's just going to infinity.

The  equation which can be represented by the algebraic model are provided in option A and option B as,

[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]

[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]

Algebraic model are the expression which consist the variables, coefficients of variables and constants.

The algebraic model are used represent the general problem in the mathematical way to solve them.

Let's check the first option,

[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]

Multiply the brackets to solve it further as,

[tex]x^2 - 2x - 3 = x^2+x-3x-3\\x^2 - 2x - 3 = x^2-2x-3[/tex]

As, the LHS is equal to the RHS. Thus, this is correct option.

Second option is given as,

[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]

Multiply the brackets to solve it further as,

[tex]x^2 - 4x+ 3 = x^2 -x-3x+3\\x^2 - 4x+ 3 = x^2 -4x+3[/tex]

As, the LHS is equal to the RHS. Thus, this is correct option.

Third option is given as,

[tex]x^2 +2x+ 3 = (x +3)(x - 1)[/tex]

Multiply the brackets to solve it further as,

[tex]x^2 +2x+ 3 = x^2 -x+3x - 3 \\x^2 +2x+ 3 = x^2 +2x - 3[/tex]

As, the LHS is not equal to the RHS. Thus, this is not correct option.

Forth option is given as,

[tex]x^2 +4x - 3 = (x+ 3)(x +1)[/tex]

Multiply the brackets to solve it further as,

[tex]x^2 +4x - 3 = x^2+ x+3x +3\\x^2 +4x - 3 = x^2+4x +3[/tex]

As, the LHS is not equal to the RHS. Thus, this is not correct option.

Hence, the  equation which can be represented by the algebraic model are provided in option A and option B as,

[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]

[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]

In order to solve for [tex](f - g)(x)[/tex] we look at the two functions and realize that:
