I need the following solutions to the following equations.
3(4x-3) -19=8x -4
-6y+14=32-4y
-28+5-3x=2-2x

Answers

Answer 1

Answer:

x = 6

y = -9

x = -25

Step-by-step explanation:

1st Equation

Step 1: Write out equation

3(4x - 3) - 19 = 8x - 4

Step 2: Solve

12x - 9 - 19 = 8x - 4

12x - 28 = 8x - 4

4x - 28 = -4

4x = 24

x = 6

2nd Equation

Step 1: Write out equation

-6y + 14 = 32 - 4y

Step 2: Solve

-2y + 14 = 32

-2y = 18

y = -9

3rd Equation

Step 1: Write out equation

-28 + 5 - 3x = 2 - 2x

Step 2: Solve

-23 - 3x = 2 - 2x

-23 = 2 + x

-25 = x

x = -25

A new car costs $8000 at full price. With a sales tax of 5.75%, how much will the car cost in total?​

Answers

Answer:

$8460

Step-by-step explanation:

So for this problem we will use the base price of $8000 and add the additional cost of the 5.75% to find the total cost for the car.

So, to find the 5.75%, we simply multiply 8000 by .0575 to get 460.

So 8000 + 460 = 8460.

Thus, the total price of the car would be $8460.

Cheers.

Answer: $8,460

Step-by-step explanation: If you multiply the cost of the car by the sales tax you get your answer. Hope this helps!

Answer:

[tex]\lim_{x\to3^-}\sin{\frac{\pi}{\floor[x]}=1[/tex]

[tex]\lim_{x\to3^+}\sin{\frac{\pi}{\floor[x]}=\frac{\sqrt3}{2}[/tex]

[tex]\lim_{x\to3}\sin{\frac{\pi}{\floor[x]}=\frac{\sqrt3}{2}[/tex]

Step-by-step explanation:

So we want to left and right hand limits of the function:

[tex]f(x)=\sin{\frac{\pi}{\floor[x]}[/tex]

as x approaches 3.

Note that the [x] means the floor function a.k.a the greatest integer function. In other words, the value of the function will be the greatest integer less than or equal to x.

1) Left

So we have the limit:

[tex]\lim_{x\to3^-}\sin{\frac{\pi}{\floor[x]}[/tex]

Note that since we're coming from the left, the values are 2.9, 2.99, and 2.999...

As I mentioned previously, the floor function outputs the greatest integer less than or equal to x.

With 2.9, 2.99, and 2.999, the greatest integer less than or equal to x is 2.

Therefore:

[tex]=\sin{\frac{\pi}{2}[/tex]

Simplify:

[tex]=1[/tex]

So:

[tex]\lim_{x\to3^-}\sin{\frac{\pi}{\floor[x]}=1[/tex]

2) Right:

[tex]\lim_{x\to3^+}\sin{\frac{\pi}{\floor[x]}[/tex]

Since we're coming from the right this time, the values are going to be 3.01, 3.001, 3.001.

And, the greatest integer less than or equal to 3.01, 3.001, and 3.001... is 3.

Therefore:

[tex]=\sin{\frac{\pi}{3}[/tex]

Simplify:

[tex]=\frac{\sqrt3}{2}[/tex]

So:

[tex]\lim_{x\to3^+}\sin{\frac{\pi}{\floor[x]}=\frac{\sqrt3}{2}[/tex]

At 3:

So we have:

[tex]\lim_{x\to3}\sin{\frac{\pi}{\floor[x]}[/tex]

The greatest integer of 3 is just 3. So:

[tex]=\sin{\frac{\pi}{3}\\[/tex]

Simplify:

[tex]=\frac{\sqrt3}{2}[/tex]

So:

[tex]\lim_{x\to3}\sin{\frac{\pi}{\floor[x]}=\frac{\sqrt3}{2}[/tex]

Spackle paint supply had a beginning inventory of 10 cans of paint at 25 per can. They purchased 20 at 30 per can. They had an ending inventory valued 500. How much paint in dollars was used for the month

Answers

Answer:

The total number of paints used for the month = $350

Step-by-step explanation:

Given that:

Spackle paint had a beginning inventory of 10 can of paint at $25 per can =

10× $25 = $250

They purchased 20 at $30 per can.

The amount of the 20 purchased can = 20 × $30 = $600

The total inventory for this supply = $600 + $250

= $850

They had an ending inventory valued 500.

The total number of paints used for the month = total inventory  - ending inventory

The total number of paints used for the month = $850 - $500

The total number of paints used for the month = $350

D. x=4 did the test on edge

Step-by-step explanation:

Which of the following is the set of all real number x such that x-2 < x-4?

Answers

If you subtract x from both sides, then you go from

x-2 < x-4

to

-2 < -4

which is a false statement. The value -2 is not smaller than -4. It's the other way around. I recommend looking at a number line to compare the two values.

This means that x-2 < x-4 is never true regardless of what x value you pick. So there are no solutions.

For all integer values of x and constant k, if (x+6)(x+k)=x^2+14x+48, what is the value of k?

Answers

Answer:

  8

Step-by-step explanation:

The product of terms on the left of the equal sign is ...

  (x+6)(x+k) = x^2 +(6+k)x +6k

So, you have two clues to the value of k. The coefficient of x must match, and the constant must match.

  6+k = 14   ⇒   k = 8

  6k = 48   ⇒   k = 8

The value of k is 8.

Find the distance between the points (3,-4) and (5, 4)

Answers

Answer:

[tex]d=2\sqrt{17}\approx8.2462[/tex]

Step-by-step explanation:

To find the distance between two points, use the distance formula.

The distance formula is:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Let (3,-4) be x₁ and y₁ and let (5,4) be x₂ and y₂. Therefore:

[tex]d=\sqrt{(5-3)^2+(4--4)^2[/tex]

Simplify:

[tex]d=\sqrt{(2)^2+(8)^2[/tex]

Square:

[tex]d=\sqrt{4+64}[/tex]

Add:

[tex]d=\sqrt{68}[/tex]

Simplify:

[tex]d=\sqrt{4\cdot17}=\sqrt4\cdot\sqrt{17}[/tex]

Simplify:

[tex]d=2\sqrt{17}\approx8.2462[/tex]

Answer:

[tex]\boxed{2\sqrt{17}}[/tex]

Step-by-step explanation:

To find the distance between two points, we use the distance formula. The distance formula is:

[tex]\boxed{d=\sqrt{(x_{2}-x_{1})^{2}+({y_{2}-y_{1})^{2}}}}[/tex]

Therefore, we can label our coordinate pairs and solve for d.

Because we are given two coordinate pairs, we will follow the standard naming system for coordinate pairs. This is [tex](x_{1}, y_{1}) \text \: {and} \: (x_{2}, y_{2})[/tex]. Therefore, we can implement the distance formula and solve.

[tex]\sqrt{(5-3)^{2}+(4-(-4))^{2}}\\\\\sqrt{(2)^{2}+(8)^{2}}\\\\\sqrt{4 + 64} \\\\\sqrt{68} \\\\\boxed{2\sqrt{17} }[/tex]

Here, E is the universal set.

A = { x : x is a multiple of 3 }

Here, we have to list the multiples of 3 less than 16

A = { 3 , 6 , 9 , 12 , 15 }

B = { x : x is a factor of 24 }

Here, we have to list the factors of 24 less than 16 }

Factor of 24 means the numbers that can divide 24 easily.

Factor of 24 includes :

B = { 1 , 2 , 3 , 4 , 6 , 8 , 12 }

C = { x : x is an odd number }

Here, we have to list the odd numbers which are less than 16

C = { 1 , 3 , 5 , 7 , 9 , 11 , 13 , 15 }

Finding A B

Here, We have to find the common elements that are present in both A and B

{ 3 , 6 , 9 , 12 , 15 } ∩ { 1 , 2 , 3 , 4 , 6 , 8 , 12 }

= { 3 , 6 , 12 }
