Answer:

the answer is 50

Step-by-step explanation:

first you plug in the x and y in the equation, making it 6(7)=-4(-2)           then, you multiply the numbers together, making the equation 42+8.                                                    finally, you add those numbers together, giving you the answer 50

Answer:

g(3.09)=C

Number of Grams of Cheese times 3.09 will = Cost

Answer:

a ≤ 20/3

Step-by-step explanation:

Subtract 4 from both sides, obtaining:

-3a ≥ -20.  Dividing both sides by -3, we get a ≤ 20/3.

Note that because this is an inequality, and because we've divided all terms by a negative number, we must change the direction of the inequality symbol from ≥ to ≤.

To calculate simple interest, use the formula Simple Interest = Principal × Rate × Time. If the rate is increased by 1%, the simple interest will increase. If the time is increased by 1 year, the simple interest will also increase.

To calculate the simple interest on a deposit, you can use the formula:

Simple Interest = Principal × Rate × Time

Now let’s address the first part of the question. If the rate is increased by 1%, the new rate would be 3% + 1% = 4%. Using the same formula, the simple interest would now be:

Simple Interest = $1200 × 0.04 × 5 = $240

Now, let’s move on to the second part of the question. If the time is increased by 1 year, the new time would be 5 years + 1 year = 6 years. Using the same rate of 3%, the simple interest would now be:

Simple Interest = $1200 × 0.03 × 6 = $216

28 divided by 7 days a week would be 4 a day

Answer: $750

Step-by-step explanation:

If the band is earning $1,500 on ticket sales, that is equal to 2/3 aka 6/15. 1/5,or, 3/15 is earned on merchandise. Since 3/15 is half of 6/15, that means that merchandise makes half of $1,500, (1500÷2) or $750.

So, the band earns $750 from merchandise

Answer: Hello!

I think that 1.1 x 103 is maybe bad written, and you wanted to write 1.1x10^3, i will solve this for this last one.

We are looking for a number that his four thousand times larger than 1.1x10^3, this number is equivalent to 4000*1.1x10^3

and we know that 4000 = 4x10^3, then we are looking for:

(4x10^3)*(1.1x10^3) = (4*1.1)x10^(3 + 3) = 4.4x10^6

So the correct answer is the option C : 4.4x10^6

Paula has a staggering total of 224 choices to choose from when customizing her friend's birthday card. That's a lot of possibilities!

Paula has quite a variety of choices for customizing her friend's birthday card!

Let's calculate the total number of different combinations she can create:

Number of sizes = 222

Number of colors = 444

Number of phrases = 777

Number of pictures = 444

To find the total number of combinations, we multiply the number of choices for each element:

2* 4* 7* 4 = 224

Complete Question:

Paula is going to choose the size, color, phrase, and picture for a birthday card for her friend. There are 2 sizes, 4 colors, 7 phrases, and 4 pictures for her to choose from. (The printing company charges a fee to add extra design elements, so she will choose only one of each.) How many different card designs are possible?

Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.

Option A is the correct option as X is let smallest integer in both. solution is given in attachment.

We know: 9 = 3²

Therefore [tex]\dfrac{1}{9}=\dfrac{1}{3^2}[/tex]

We know the property:

We must find f(5). Put x = 5 to the equation of the function:

[tex]f(5)=3^{5-2}=3^3=3\cdot3\cdot3=27[/tex]

The value of f(5) is 27 of function f(x) = 1/9(3)ˣ

The function is defined as mathematics expression defines a relationship between one variable and another variable. When we say that a variable quantity y is a function of a variable quantity x, we indicate that y depends on x and that  value of x determines what value of  y  will be. This relationship can be expressed as follows: y = f (x)

An exponential function is defined as function has a constant as its base and a variable as its exponent.

In mathematical form an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function.

For the function f defined by f(x) given as :

f(x) = 1/9(3)ˣ ,

To determine the value of f(5).​

f(x) = 1/9(3)ˣ,

Substitute the value of x = 5 in the function,

f(5) = 1/9(3)⁵ ,    [ 3⁵ = 243 ]

f(5) = 1/9(243),

f(5) = 27

Hence, the value of f(5) is 27.​

2x + 50 = 4x + 25

To isolate x, first subtract 50 from both sides of the equation.

2x + 50 - 50 = 4x + 25 - 50

2x = 4x - 25

Then, subtract 4x from both sides.

2x - 4x = 4x - 25 - 4x

-2x = -25

Lastly, divide both sides by -2.

x = 12.5

Check work

Substitute 12.5 for every x in the equation.

2(12.5) + 50 = 4(12.5) + 25

25 + 50 = 50 + 25

75 = 75

As you can see, the statement is true; 12.5 is correct.

x = 12.5 or x = [tex]12\frac{1}{2}[/tex]

When rotating a point 180 degrees about the origin, you are simply inverting the points.

(5, -2) rotated 180 degrees results in (-5, 2).

To rotate point B(5, -2) 180 degrees about the origin, its image would have coordinates (-5, 2).

To rotate a point about the origin, we can use the formula (x', y') = (-x, -y). In this case, point B has coordinates (5, -2). To rotate it 180 degrees about the origin, we substitute the coordinates into the formula:

(x', y') = (-5, 2)

So this is essentially a proportion problem. They want you to be able to recognize a relationship between the two. The easiest way to go about this is to draw a picture (I have included one). What you want to do is notice that you are given both shadow lengths. This is essentially going to be your first step to creating the proportion.

Understanding that we know the shadow lengths, we can turn these into a fraction such as so:

4ft/20ft.

Now that we know that, we need to look at are unknown. Our unknown is the height of the utility pole. We can solve this by substituting for X since we know the utility worker is 5.5 ft tall.

Your fraction for that would look like:

5.5ft/X

Make sure to always make your top to top match, such as since I put the utility worker's shadow on top, I need to put his height on top.

Now we can solve.

4ft/20ft =5.5ft/X

We need to cross multiply to get an equation we can work with. If we cross multiply, Your equation will look like:

4x = 110ft

This is a simple one step equation. Divide both sides by 4 to get your answer.

x= 27.5ft.

This means your Utility pole's height is 27.5ft.

To find the height of the utility pole, set up a proportion with the utility worker's height and shadow length as one ratio, and the utility pole's height and shadow length as the other ratio. Solve the proportion by cross-multiplying and simplifying the equation. The height of the utility pole is 27.5 feet.

To find the height of the utility pole, we can set up a proportion with the utility worker's height and shadow length as one ratio, and the utility pole's height and shadow length as the other ratio. Let's call the height of the utility pole 'x'. The proportion can be written as:

(5.5 ft) / (4 ft) = x / (20 ft)

Cross-multiplying, we get:

(5.5 ft) * (20 ft) = 4 ft * x

Simplifying, we find:

x = (5.5 ft * 20 ft) / 4 ft = 27.5 ft

Therefore, the height of the utility pole is 27.5 feet.

3(x + 7) ≥ 2x + 6

Distributive property.

3x + 21 ≥ 2x + 6

Subtract 2x from both sides.

x + 21 ≥ 6

Subtract 21 from both sides.

x ≥ -15

The solution to the inequality is [tex]\(x \geq -15\)[/tex].

To translate the given statement into an inequality, you can follow these steps:

1. **Translate the first part of the sentence:**

  "Three times the sum of x and seven" can be written as \(3(x + 7)\).

2. **Translate the second part of the sentence:**

  "The sum of two x and six" can be written as \(2x + 6\).

3. **Combine the translated parts with the inequality:**

  "Three times the sum of x and seven is greater than or equal to the sum of two x and six" can be translated into the following inequality:  

[tex]\[3(x + 7) \geq 2x + 6\][/tex]

4. **Solve the inequality for x:**

  Distribute the 3 on the left side:  

[tex]\[3x + 21 \geq 2x + 6\][/tex]

  Move the \(2x\) term to the left side by subtracting \(2x\) from both sides:

[tex]\[3x - 2x + 21 \geq 6\][/tex]

  Simplify:

[tex]\[x + 21 \geq 6\][/tex]

  Move the 21 to the right side by subtracting 21 from both sides:

[tex]\[x \geq -15\][/tex]

So, the solution to the inequality is \(x \geq -15\). This means any value of \(x\) greater than or equal to -15 will satisfy the given inequality.
