Answer:

x has the values -4 and -3

Step-by-step explanation:

x² + 7x + 12 = 0

x² + 3x + 4x + 12 = 0

x(x + 3) + 4(x + 3) = 0

(x + 4)(x + 3) = 0

Answer:

21%

Step-by-step explanation:

Another 10% increased means it becomes 110*110/100 = 121. The first 10% increase means the second 10% increase will be an actual 11% increase from the original, so it will be a total of 21%.

Answer:

Step-by-step explanation:

Because the first 10% increase is calculated as 10% of what you started with. The second 10% is 10% of what you started with plus 10% of the increase caused by the original 10% increase.

Let's do the maths…

Let's start with 100 to make things easy.

We know that 10% of 100 is 10.

We know that 20% of 100 is 20.

So if we increase 100 by 10% we get 110.

If we increase 100 by 20% we get 120.

Now lets do the 10% plus 10%.

From the first 10% increase we were left with 110.

Now if we take 10% of the 110 we have 11.

Add that to the 110 and we get 121.

This is why people are surprised how quick a lone can rise if we don't pay it off. We are paying interest on the basic sum plus interest on the interest, then interest on the interest on the interest.

Answer:

-2.5x-20

Step-by-step explanation:

-2.5x-20

Answer:

-2.5x - 20

Step-by-step explanation:

"20 less than..." means that you are subtracting 20 from something else, and that something else is usually the next thing in the phrase. it's tricky because it's first in the phrase, but in the expression, it will come last, or after the next operation (which, in this case, is "the product of -2.5 and a number x). the key is to pay attention to the wording. "the product of -2.5 and a number x" is something that can stand alone, but "20 less than" depends on something else, so that's generally how you can tell that it's going to be written after something else, if that makes sense.

"...the product of -2.5 and a number x" means that you are multiplying -2.5 and x. "a number x" just means that x is a variable and its numeric value is currently unknown.

so, as an expression, this would be -2.5x - 20. i hope this helps and i hope my explanation made sense lol! have a lovely rest of your day <3

Answer:

n²-n

Step-by-step explanation:

for example for the second term

2²=4

4-2=2 and so it works

From the given frequency table,

Frequency represents the number of people who made the calls.

Total number of people who made the calls = 16 + 11 + 5 + 3 + 1

                                                                          = 36

Number of people who made less than 13 calls = 16 + 11 + 5

                                                                                 = 32

Number of people who made at least 9 calls = 5 + 3 + 1

                                                                            = 9

Percentage of people who made at least 9 calls = [tex]\frac{\text{Number of people who made at least 9 calls}}{\text{Number of people who made the calls}}\times 100[/tex]

= [tex]\frac{9}{36}\times 100[/tex]

= 25%

Difference in the number of people who made the calls between 5-8 calls than 13-16 calls = 11 - 3 = 8

Measurement of 5 quarts is equal to 20 cups.

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object.

We have the measurement, 1 cup = 1/4 quarts

Let x be the number of quarts for 20 cups.

By using proportion,

1 / (1/4) = 20 / x

Cross multiplying,

x = 20 × (1/4)

x = 5

Hence the measurement of 20 cups is equal to 5 quarts.

Thee measurement equals to 20 cups is 5 quarts.

Thus, option (a) is correct.

To determine which measurement is equal to 20 cups, compare the conversion factors between cups and each of the given measurements.

As, the conversion factors are:

1. 5 quarts

= 5 x  4 cups/quart

= 20 cups

2. 40 pints

= 40 x  2 cups/pint

= 80 cups

3. 1 gallon

= 1 x  16 cups/gallon

= 16 cups

4. 320 fluid ounces

= 320 x  0.125 cups/fluid ounce

= 40 cups

Complete Question:

The amount of money, y, pizzeria W makes by selling x pizzas can be modeled by the equation y = 15x. The relationship of the amount of money pizzeria L makes is shown in the following graph.

Which pizzeria makes more money per pizza?

A. Pizzeria L makes more money per pizza.

B. Pizzeria W makes more money per pizza.

C. They make the same amount per pizza.

Answer:

B. Pizzeria W makes more money per pizza.

Step-by-step explanation:

The proportional relationship showing how amount of money made(y) is related to the amount of pizzas sold (x) for pizzeria W is given by the equation y = 15x.

the constant of proportionality/unit rate, k = 15.

This represents the amount in dollars, made per pizza.

So, Pizzeria W makes $15 per pizza.

For Pizzeria L, using any point on the line, say, (2, 24),

k = y/x = 24/2 = 12.

This represents the unit rate, which is the amount Pizzeria L makes per pizza.

Thus, Pizzeria L makes $12 per pizza.

We can conclude that, Pizzeria W makes more money per pizza.

Answer:

The answer is D. 1/2

Step-by-step explanation:

Because the probability of getting each gift card is 1/4. So since the student picks it without replacement, this means that we're multiplying 1/4 X 1/3 which would equal 1/12. Now we multiply 1/12 by 6 because there are six different variations of getting the cards. This would give us 6/12 or 1/2.

Step-by-step explanation:

x = 3

y = -3

(3, -3)

Step-by-step explanation:

Choose one of the equations and isolate y. I will use the first one.

2x + y = 3

Y = 3 - 2x

Now sub the solution for y into the equation below.

3x - y = 3

3x - (3 - 2x) = 12

3x - 3 + 2x = 12

5x - 3 = 12

5x = 15

x = 3

To get y, sub the answer for x into one of the equations.

2(3) + y = 3

6 + y = 3

y = 3 - 6

y = -3

Answer:

(x,)y) =(3,-3)

Step-by-step explanation:

add the equations vertically to eliminate one variable

2x +y = 3

3x -y = 12

5x =15    divide both sides by 5

x  = 3       now substitute the given value of x into the equation  2x+y=3

2 x 3 + y = 3  multiply 2x3

6 +y =3           move constant to the right

y = 3-6

y = -3
