Answers

Answer 1
the correct answer is -14
Answer 2
Let's plug in the variables. 

(-8) - 3 - 3 is the same as saying -8 + -3 + -3

Solve 11kx + 13kx = 6 for x.
A. X= 1/4k
B. X= 4k
C. X= 4/k
D. X= k/4

Answers

24kx = 6
kx = 6/24
kx = 1/4
x = 1/4/k
x = 1/4k

Answer: A) X = 1/4k or the first option.

Answer:

Option (a) is correct.

[tex]x=\frac{1}{4k}[/tex]

Step-by-step explanation:

Given: Equation 11kx + 13kx = 6

We have to solve for x and choose the correct option from the given options.

Consider the given equation  11kx + 13kx = 6

Taking kx common, we have,

kx (11+13) = 6

Simplify, we have,

24kx = 6

Divide both side by 24, we have,

[tex]kx=\frac{6}{24}[/tex]

Simplify, we have,

[tex]kx=\frac{1}{4}[/tex]

Divide both side by k, we have,

[tex]x=\frac{1}{4k}[/tex]

Thus, Option (a) is correct.

Gio is solving the quadratic equation by completing the square 5x^2+15x-4=0 What's should gio do first?

Answers

Gio should first complete the square by adding and subtracting [tex]\((\frac{3}{2})^2\)[/tex], leading to the equation [tex]\((x + \frac{3}{2})^2 = \frac{25}{4}\).[/tex]

To solve the quadratic equation [tex]\(5x^2 + 15x - 4 = 0\)[/tex] by completing the square, Gio should follow these steps:

1. Make the Coefficient of [tex]\(x^2\) 1:[/tex]

Divide the entire equation by the coefficient of [tex]\(x^2\)[/tex] to make it equal to 1. In this case, divide the equation by 5:

[tex]\[x^2 + 3x - \frac{4}{5} = 0.\][/tex]

2. Move the Constant to the Other Side:

Move the constant term to the other side of the equation:

[tex]\[x^2 + 3x = \frac{4}{5}.\][/tex]

3. Complete the Square:

  Add and subtract [tex]\((\frac{3}{2})^2\)[/tex] inside the parentheses to complete the square:

 [tex]\[x^2 + 3x + (\frac{3}{2})^2 = \frac{4}{5} + (\frac{3}{2})^2.\][/tex]

4. Factor the Perfect Square Trinomial:

  Factor the left side, which now is a perfect square trinomial:

 [tex]\[(x + \frac{3}{2})^2 = \frac{25}{4}.\][/tex]

5. Solve for (x):

  Take the square root of both sides and solve for (x):

[tex]\[x + \frac{3}{2} = \pm \frac{5}{2}.\][/tex]

6. Isolate (x):

  Isolate (x) on one side to find the solutions:

  [tex]\[x = -\frac{3}{2} \pm \frac{5}{2}.\][/tex]

Therefore, Gio should first complete the square by adding and subtracting [tex]\((\frac{3}{2})^2\)[/tex], leading to the equation [tex]\((x + \frac{3}{2})^2 = \frac{25}{4}\).[/tex]

A sum of money is invested at 12% compounded quarterly. About how long will it take for the amount of money to double?

Compound interest formula: (image uploaded V(t) )

t = years since initial deposit
n = number of times compounded per year
r = annual interest rate (as a decimal)
P = initial (principal) investment
V(t) = value of investment after t years

A. 5.9 years
B. 6.1 years
C. 23.4 years
D. 24.5 years

Answers

Follow the given formula.  The initial amount of money invested, P, becomes 2P (same thing as "doubles) after t years.  Since compounding is quarterly, n=4.  The annual interest rate is 12%.  That is, r=0.12.

Then we have 2P = P (1 + 0.12/4)^(4t) and need only solve for time, t.

Simplifying the above equation:  2 = (1.03)^(4t)

We must isolate 4t, and then isolate t.  To do this, take the common log of both sides of the above equation.  We get:

log 2 = (4t) log 1.03.  This gives us 4t = [log 2] / [log 1.03], or

4t =  23.4498

Dividing both sides by 4, we get     t = 5.86 (years).

Compound interest is the interest generated overtime on a sum of money invested. The time it will take for the amount of money to double is 5.9 years

How to calculate the compound interest?

Compound interest is the interest generated overtime on a sum of money invested. The formula for calculating compound interest is expressed as:
V(t) = P(1+r/n)^nt

where:

t = years since initial depositn = number of times compounded per yearr = annual interest rate (as a decimal)P = initial (principal) investmentV(t) = value of investment after t years

Given the following

V(t) = 2P
r = 0.12
n = 4

Substitute
2P = P(1+0.12/4)^4t
2 =  (1.03)^4t
ln2 = 4t ln(1.03)
0.6931 = 0.1182t
t = 0.6931/0.1182
t = 5.9 years

Hence the time it will take for the amount of money to double is 5.9 years

A publisher estimates their costs of publishing a book is from $980,000 to $1,240,000. So far, they have spent $824,000. Which compound inequality correctly expresses how much more the publisher can spend?

$155,850 ≥ x ≤ $415,850

$155,850 ≤ x ≥ $415,850

$155,850 ≥ x ≥ $415,850

$155,850 ≤ x ≤ $415,850

Answers

The least amount the publisher can spend is:
980,000 - 824,000 = 156,000

The greatest amount the publisher can spend is:
1,240,000 - 824,000 = 416,000

The range of amount the publisher is left to spend is given by:
156,000 ≤ x ≤ 416,000

Answer: Fourth option (D)

Answer:

[tex]155,850 \leq  x \leq 415,850[/tex]

Step-by-step explanation:

A publisher estimates their costs of publishing a book is from $980,000 to $1,240,000.

Let x be the amount publisher can spend

So, [tex]980000\leq x \leq 1240000[/tex]

Now we are given that  So far, they have spent $824,000

So, [tex](980000-824000)\leq x \leq (1240000-824000)[/tex]

[tex]156000\leq x \leq 416000[/tex]

So, Option D is true

Hence compound inequality correctly expresses how much more the publisher can spend is [tex]155,850 \leq  x \leq 415,850[/tex]

The cost of renting a car is $35/wk plus $0.25/mi traveled during that week. An equation to represent the cost would be y = 35 + 0.25x, where x is the number of miles traveled. If your cost was $51.25, how many miles were you charged for traveling?

Answers

Final answer:

To find the number of miles traveled when the total cost is $51.25, subtract the base cost from the total and divide by the per-mile rate, resulting in 65 miles traveled.

Explanation:

The question asks how many miles were traveled if the total cost for renting a car was $51.25. According to the equation y = 35 + 0.25x, where y represents the total cost and x represents the miles traveled, we first need to subtract the base cost of $35 from the total cost to find out how much is charged for the mileage.

Here is how you calculate it:

Subtract the weekly rental cost from the total cost: $51.25 - $35 = $16.25. Divide the remaining cost by the cost per mile: $16.25 / $0.25 = 65 miles.

Therefore, you were charged for traveling 65 miles.

Car X leaves Northtown traveling at a steady rate of 55 mph.  Car Y leaves 1 hour later following Car X, traveling at a steady rate of 60 mph.  Which equation can be used to determine how long after Car X leaves Car Y will catch up?

Answers

The equation that can be used to determine how long after Car X leaves Car Y will catch up is D. 55x = 60(x - 1).

To determine when Car Y will catch up to Car X, we need to find the time it takes for Car Y to cover the same distance as Car X. Since Car Y leaves 1 hour later, it will travel for (x - 1) hours, where x represents the time Car X has been traveling. So, the equation would be:

D. 55x = 60(x - 1)

This equation accounts for the distance traveled by both cars over the same time frame, considering Car Y started an hour later.

A senior class is selling lanyards as a fundraiser. The profit for each lanyard is $0.75. Write and solve an inequality to determine the number of lanyards the class must sell to make a profit of at least $250.

Answers

0.75x > = 250
x > = 250/0.75
x > = 333.33....so they would have to sell at least 334 of them
Ok so lets say that the number of lanyards is equal to b. We have to write an equation that solves for b. That would be:

0.75b ≥ 250

Now you solve the equation

0.75b ≥ 250
——— —— (divide both sides by 0.75)
0.75 0.75

b ≥ 333.3

You have to round that up because you can’t sell part of a lanyard. So the answer is:

The seniors have to sell at least 334 lanyards.
