13x - 12 = 7x - 6 is the equation

6x - 12 = -6

6x = 6

x = 1

Let's check!

13(1) - 12 = 7(1) - 6

13 - 12 = 7 - 6

1 = 1

Answers

Answer:

a₈ = 768 , a₁₀ = 3072

Step-by-step explanation:

The nth term of a GP is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 6 and r = 2 , then

a₈ = 6 × [tex]2^{7}[/tex] = 6 × 128 = 768

a₁₀ = 6 × [tex]2^{9}[/tex] = 6 × 512 = 3072

Solve the inequality, write the answer in interval notation.

Answer:

  (-∞, 2-√7) ∪ (2+√7, ∞)

Step-by-step explanation:

The factored form of a polynomial is helpful for solving related inequalities. For quadratics with two real zeros, the sign changes at each zero. If the leading coefficient is positive, the sign is positive to for x-values "outside" either zero, and is negative between the zeros.

Your inequality can be written in standard form as ...

  x² -4x -3 > 0

  x² -4x +4 -7 > 0

  (x -2 -√7)(x -2 +√7) > 0 . . . . . factor the difference of squares (x-2)² -7

The zeros are at x=2-√7 and x=2+√7, so the product of these factors will be positive for x < 2-√7 and x > 2+√7. The solution in interval notation is ...

  (-∞, 2-√7) ∪ (2+√7, ∞)

_____

Additional comment

We suspect a typo in the problem statement. If it were to read ... > -3, then the zeros would be at 1 and 3, and the solution would be (-∞, 1)∪(3, ∞).

Charlie ate ¾ cup dry food for breakfast and another ½ cup for dinner. If the food
has a caloric density of 360kcal/cup, how many kcal did Charlie eat in total? Please show work!

Answers

Answer: 450 kcal

Step-by-step explanation:

So you know the food is 360 kcal per 1 cup

by setting up a proportion, you can relate the number of kcal to cups.

[tex]\frac{360 kcal}{1 cup} = \frac{?kcal}{(3/4 +1/2)cup} \\\\[/tex]

we can simplify the fraction to this:

[tex]\frac{360 kcal}{1 cup} = \frac{?kcal}{(5/4)cup} \\\\[/tex]

by cross multiplying you can solve the proportion

(360) * (5/4) = (?) * (1)

simplifying gets this:

450 = ?

so he ate 450 kcal total

0.04 with 4 repeating as a fraction. Not the 04 repeating just the 4 is repeating. What is the answer???

Answers

Answer:

2/45

Step-by-step explanation:

0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as: [tex](\frac{1}{10} )(\frac{4}{9} )[/tex]. Multiplying the two fractions results in 4/90 which can be simplified to 2/45.

what is the slope and y intercept of −5x = 8−y

Answers

Answer:

im pretty sure its -5

Step-by-step explanation:

The slope-intercept form is  y = m x + b

where  m

is the slope and  b

is the y-intercept.

y = m x + b

Using the slope-intercept form, the slope is  

− 5 . m = − 5                                                                                                                        i think im right but if this helpful  your welcome uwu                    

Answer:

Slope is 5 and y-intercept is 8

Step-by-step explanation:

-5x = 8 - y                   Solve for y

-5x - 8 = -y                

  5x + 8 =  y                 multiply by -1

  So y = 5x + 8

   Using y = mx + b      "m"     is the slope 5     "b" is the y-intercept

Joy has some pairs of shoes six pairs of them are sneakers what expression shows how many pairs of shoes joy has that are not sneakers

Answers

To find the number of shoes that are not sneakers, 1. Take the total amount of sneakers, 2. Subtract the amount of sneakers Joy does have. So basically the equation is: NONsneaker shoes = TOTAL shoes - sneakers. To make an actual equation, put the number 6 in the equation to represent the number of sneakers. Then use two DIFFERENT coefficients, one to represent nonsneaker shoes, and the other to represent total shoes. One example of what this equation can look like is… n = 6 - s

Answer:

  1/x = (1+√5)/2 ≈ 1.618034

Step-by-step explanation:

Since you are only interested in the second part, we presume you have solved the quadratic equation to find ...

  x = (√5 -1)/2 ≈ 0.618034

The second part asks for 1/x. The usual method for rationalizing the denominator will be useful for this. Multiply numerator and denominator by the conjugate of the denominator.

  [tex]\dfrac{1}{x}=1\div\dfrac{\sqrt{5}-1}{2}=1\times\dfrac{2}{\sqrt{5}-1}\\\\=\dfrac{2(\sqrt{5}+1)}{(\sqrt{5}-1)(\sqrt{5}+1)}=\dfrac{2\sqrt{5}+2}{5-1}=\boxed{\dfrac{\sqrt{5}+1}{2}\approx1.618034}[/tex]

Step-by-step explanation:

The linear equation of the total amount paid in the first 12 months will be y = 64.48x - 2.48.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Modern Electronics offers a one-year monthly installment plan for a big-screen TV.

The payment for the first month is $62, and then it increases by 4% each month for the rest of the year.

Then the payment after a month will be

Monthly payment = 1.04 × 62

Monthly payment = $64.48

Then the linear equation of  the total amount paid in the first 12 months will be

y = 64.48(x - 1) + 62

Where y is the cost and x is the number of months.

The equation can be written as

y = 64.48x - 2.48
