Step by step explanation

Answers

Answer:

x = 6

Step-by-step explanation:

Rearrange terms

4  +  3  =  2 2

3  +  4   =  2 2

Subtract   4  from both sides of the equation

3x+4=22

3 + 4 − 4 = 2 2 − 4

Simplify  (Subtract the numbers )

3 = 1 8

Divide both sides of the equation by the same term

3 = 1 8

3 / 3 = 1 8 /3

Simplify  (Cancel terms that are in both the numerator and denominator

Divide the numbers )

= 6

If you are dividing X and Y values, does the Y value go on the top or bottom?

Step-by-step explanation:

A bakery sells bagels at two different rates. When a customer buys fewer than 12 bagels, each one costs $1.25. When a customer buys 12 or more bagels, the first 12 bagels cost $1 each and each additional bagel costs $0.75.

Which TWO inequalities and constraints below represent the price for b bagels??

Question 1 options:

1.25b when b 12


1b when b < 12, then 0.75b


1b when b ≤ 12, then 0.75b


0.75b for b < 12, then 1b


0.75b for b ≤ 12, then 0.75b

Answers

Answer:

1.25b when b < 12 , 1b & then 0.75 b when b > 12

Step-by-step explanation:

Price for b bagels = Price x Quantity

* Less than 12 bagels bought, cost $1.25 per bagel

So, price for b bagels, when (b < 12) = 1.25b

* 12 or more than 12 bagels bought, cost $1 upto first 12 bagels & 0.75b on each additional bagel

So, price for b bagels, when (b = 12) = b

So, price for b bagels, when (b > 12) = b + 0.75b' , where b' denotes extra b beyond 12

The inequality used to represent this constraints is:

Price = 1.25b  when b < 12

Price = 0.75b + 3 when b ≥ 12

Inequalities is an expression used to show the non equal comparison of numbers and variables.

Let b represent the number of bagels bought.

When a customer buys fewer than 12 bagels, each one costs $1.25. Hence:

Price = 1.25b  when b < 12

When a customer buys 12 or more bagels, the first 12 bagels cost $1 each and each additional bagel costs $0.75. Hence:

Price = 12 + (b - 12)0.75 = 0.75b + 3 when b ≥ 12

The inequality used to represent this constraints is:

Price = 1.25b  when b < 12

Price = 0.75b + 3 when b ≥ 12

Answers

Answer:

D. 224 inches

Step-by-step explanation:

Length of the new rectangle after dilation = 22 × ⁷/2 = 77 inches

Width of the new rectangle after dilation = 10 × ⁷/2 = 35 inches

Perimeter of rectangle = 2(length + width)

f(x) = 2(x – 1)– 5 and g(x) = – 2x + 1 , determine the x-values of the points of intersection.

Answers

Answer:

             x = 2

Step-by-step explanation:

These are equations of lines with different slopes, so there is only one point of their intersect.

The point of intersect is where f(x) = g(x).

2(x - 1) - 5 = - 2x + 1

 +2x            +2x

2x - 2 - 5 + 2x = 1

       +7               +7

          4x = 8

        ÷4     ÷4

          x = 2

Answer: x = 2

Explanation:

From the way you were referring to the x-values as plural, I assumed there were multiple x-values and multiple points of intersection, but these are linear equations, so one x-value it is!

Simply f(x)=2(x-1)-5 into f(x)=2x-7. Just plug in 2x-7, in order to make it equal to -2x+1. That would make the equation 2x-7=-2x+1. Add 7 to both sides to make it 2x=-2x+8. Add 2x to both sides to make it 4x=8. Divide 4 to both sides and that results with x=2.

Find the volume of a right circular cone that has a height of 15.2 cm and a base with a diameter of 11.9 cm. Round your answer to the nearest tenth of a cubic centimeter.

Answers

9514 1404 393

Answer:

  563.5 cm³

Step-by-step explanation:

Use the formula for the volume of a cone:

  V = (1/3)πr²h

Recognize that the radius is half the diameter:

  r = (11.9 cm)/2 = 5.95 cm

  V = (1/3)π(5.95 cm)²(15.2 cm) ≈ 563.516 cm³

The volume of the cone is about 563.5 cm³.

If you use 3.14 for the value of π, then the result will be 563.2 cm³.

LOTS OF POINTS!?!?!?Write a linear function f with the values f(5)=−1 and f(0)=−1.
f(x)=

Answers

Answer:

The euation of the linear function is:

y = -1

Step-by-step explanation:

As the function has the values

at x = 5, f(5) = -1at x = 0, f(0) = -1

Thus, the two points are:

(5, -1)(0, -1)

Finding the slope between (5, -1) and (0, -1)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-1\right)[/tex]

[tex]m=\frac{-1-\left(-1\right)}{0-5}[/tex]

[tex]m=0[/tex]

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept

We also know that the y-intercept can be computed by setting x=0 and finding the corresponding value of y.

so at x = 0, y = -1

Thus, the y-intercept 'b' = -1

Now, substituting m = 0 and b = -1 in the slope-intercept form of the line equation

y = mx+b

y = 0x + -1

y = -1

Therefore, the euation of the linear function is:

y = -1

What is the focus of the parabola? y=−1/4x^2 −2x − 2

Answers

Answer:

Step-by-step explanation:

This is a doozy. You have to know A LOT about parabolas to get to this answer. First and foremost, we will have to complete the square on the x terms and get everything else on the other side of the equals sign with the intention of putting this into standard form which looks like this:

[tex]-4p(y-k)=(x-h)^2[/tex]

The negative is because the parabola is upside down. We begin breaking it down by multiplying everything by -4 to get:

[tex]-4y=x^2+8x+8[/tex] and subtract that 8 from both sides to get:

[tex]-4y-8=x^2+8x[/tex]. Now we'll complete the square on the x terms by taking half the linear term, squaring it, and then adding it to both sides. Our linear term (the number with the x stuck to it) is 8. Half of 8 is 4 ad 4 squared is 16. So we add 16 to both sides to get:

[tex]-4y-8+16=(x^2+8x+16)[/tex]

The right side will simplify into a perfect square binomial and the left side we will just combine like terms to get:

[tex]-4y+8=(x+4)^2[/tex]

We're getting close. Now we need to just factor out the -4 on the left to get:

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

If the standard form is -4p blah blah blah, then p has to be 1. That means that the focus is 1 unit below the vertex. The vertex is (-4, 2). p is the distance between the vertex and the focus. The focus is always on the axis of symmetry. We know that the parabola opens upside down because of the negative sign, and the parabola always wraps itself around the focus. That's why the focus is p units below the vertex. That means that the focus is located at (-4, 1).

Told you it was difficult. I noticed no one helped you with this one and it's been up here for 5 days...

A jewelry box contains 13 gold earrings, 10 silver earrings and 12 titanium
earrings. Two earrings are drawn at random with replacement. Find the
probability that they are made of different materials.

Answers

Answer:

The probability is 406/625

Step-by-step explanation:

If they are of different materials, we have the following combinations of selection;

(gold and silver) or ( silver and titanium) or (gold and titanium )

The number of earrings present is 13 + 10 + 12 = 25

Probability of selecting a gold earring is 13/25

Probability of a silver is 10/25

Probability of a titanium is 12/25

Substituting these into the probabilities, we have;

(13/25 * 10/25) + (10/25 * 12/25) + (13/25 * 12/25)

= 130/625 + 120/625 + 156/625 = 406/625

Mutual Fund X owns 0.5% of the total stock of Company Y. In one particular year, Company Y announces annual profits of $12,000,000, and decides to pay dividends to its shareholders at a rate of 15% of its annual profits. How much will Mutua

Answers

Answer: $9,000

Step-by-step explanation:

First calculate the total dividends that Company Y plans to pay.

= 12,000,000 * 15%

= $1,800,000

Then calculate the amount that Mutual fund X will get.

They own 0.5% of the total stock of Company Y so they will get;
