Hello!

To answer this question we need to find the factors of -120.

The total set (both negative and postive! ) are the following:

After looking over all of these factors, we can see that 10 · -12 is equal to not only -120, but when the multiplication sign is replace by addition, it is equal to -2!

Hope this helps.

Final answer:

The two numbers that multiply to -120 and add to -2 are 10 and -12. These satisfy the given conditions of multiplication and addition.

Explanation:

To find two numbers that multiply to -120 and add to -2, we can set up a system of equations based on the factors of -120. We know that if two numbers multiply to a negative number, one must be positive and the other negative. So we look for two factors of 120 with a difference of 2, given that one will be negative and the other positive.

Considering the factor pairs of 120: (1, 120), (2, 60), (3, 40), (4, 30), (5, 24), (6, 20), (8, 15), (10, 12), we find that 10 and -12 satisfy both conditions: 10 * -12 = -120 and 10 + (-12) = -2.

1m = 100cm.  

so since the ladybug is 2cm.  

you divide 2 by 100, which you will get 0.02m (divide by 100 means moving the dot two times to the left. thats why it leaves you 0.02m)

0.02 meters would be the length of the lady bug  because 1 cm is equal to 0.01 meters

Answer: A. Based on the law of syllogism, if two lines meet at a 90 angle, then they have opposite reciprocal slopes.

Step-by-step explanation:

Law of Syllogism which is also known as reasoning by transitivity is a valid argument method of a deductive reasoning that follows a sequence.

Its similar to the transitive property of equality, which states that if a=b and b=c then a=c

The given statement :  If two lines meet at a 90 angle, they are perpendicular. If two lines are perpendicular, they have opposite reciprocal slopes.

let a →" two lines meet at a 90 angle"

b→ "two lines are perpendicular are perpendicular"

c→" two lines have opposite reciprocal slopes"

Since a→b and b→c

Therefore by law of syllogism, a→c

i.e. If two lines meet at a 90 angle, then they have opposite reciprocal slopes.

A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time.

“Or” indicates that, as long as either statement is true, the entire compound sentence is true.

Now as shown in the graph, the solution inequality of the graph is :

x > 3 and x < 5   [please note, circles in the graph indicate exclusion, dots indicate inclusion. in the graph given circles are shown, so it depicts exclusion]

Now let's solve each option to find if it fits in with the above inequality

Option 1 : 2x-4 > 6 or 3x < 9

⇒ x > 5 or x < 3

Option 2 : 2x - 4 < 6 and 3x > 9

⇒ x < 5 and x > 3

Option 3 : 3x + 8 > -7 or -4x < 12

⇒ 3x > -15 or x < -3

⇒ x > -5 or x < -3

Option 4 : 3x + 8 < -7 and -4x > 12

⇒ 3x < -15 and x > -3

⇒ x < -5 and x > -3

So the compound sentence in option 2 : 2x - 4 < 6 and 3x > 9

has its solution set on the graph.

Final answer:

The correct expression to find the temperature difference between the low and high temperatures when the temperature rose as much above zero as it was below zero is 5 + 5 degrees, which equals 10 degrees in total.

Explanation:

The question involves finding the difference in temperature from a low of -5 degrees Fahrenheit to a high that is as many degrees above zero as the low was below zero. To calculate the difference, we consider the increase in temperature from the low to 0 degrees, which is 5 degrees, and then the additional increase to the high temperature, which is also 5 degrees above zero. Therefore, the total change in temperature is 5 degrees (to get to zero) plus another 5 degrees (to reach the high), totaling 10 degrees.

The correct expression to find the number of degrees between the low and high temperatures would be C. 5 + 5, representing the increase from -5 degrees to 0, and from 0 to +5 degrees, respectively.

[tex]2x+4=16\\\\2x=12\\\\x=6[/tex]

The solution to the equation 2x + 4 = 16 is x = 6.

Given the equation in the question:

2x + 4 = 16

To solve the equation 2x + 4 = 16, first, isolate the variable term on one side by moving the constant term to the other side of the equation.

2x + 4 = 16

Subtract 4 from both sides of the equation:

2x + 4 - 4 = 16 - 4

2x = 16 - 4

Subtract 4 from 16:

2x = 12

Divide both sides of the equation by 2 to isolate the variable x:

2x/2 = 12/2

x = 12/2

x = 6

Therefore, the value of x is 6.

Answer:

38%

Step-by-step explanation:

Given that X,the hours per week the music student practice follow a normal distribution.

X:N(8,4)

We have to find the percentage of students who practice between 6 and 10 hours.

6<x<10 implies converting to z

We know z = (x-mean)/sigma = (x-8)/4

Hence 6<x<10 is equivalent to (6-8/4)<Z<(10-8/4)

= |z|<0.5

From std normal table we find this area equals = 0.1915+0.1915

=0.3830 = 0.38 (rounded off)

Hence required percentage = 0.38x100 = 38%

Final answer:

To determine the percentage of music students practicing between 6 to 10 hours, we convert these hours to z-scores and use the standard normal distribution table, which reveals that approximately 38.2% of students practice within this range.

Explanation:

To find the percentage of music students who practice between 6 to 10 hours per week, we can use the properties of the normal distribution. We first need to convert the range values to z-scores using the formula Z = (X - μ) / σ, where X is the value from the data set, μ is the mean, and σ is the standard deviation.

Converting 6 hours to a z-score:
Z = (6 - 8) / 4 = -0.5

Converting 10 hours to a z-score:
Z = (10 - 8) / 4 = 0.5

Now we use the standard normal distribution table to find the probability corresponding to these z-scores. The area under the curve between z-scores -0.5 and 0.5 gives us the desired percentage. Looking up the z-scores in the standard normal distribution table, we find that the area between these scores is approximately 38.2%. Thus, 38% is the closest option provided.

the change will be 1.50 because 7.50 minus 9.00 is 1.50

The percent change between $7.50 and $9.00 is calculated by subtracting the initial value from the final value, dividing that by the initial value, and multiplying by 100%. This results in a percent change of 20%.

The percent change between two values is calculated by subtracting the initial value from the final value, dividing the result by the initial value, and then multiplying by 100%. In your case, you want to find the percent change between $7.50 and $9.00.

Start by subtracting the initial value ($7.50) from the final value ($9.00). This gives us $1.50.

Then, divide $1.50 by the initial value ($7.50), giving us 0.2.

Finally, multiply 0.2 by 100% to get the percent change, which is 20%. So the percent change between $7.50 and $9.00 is 20%.

Two consecutive odd numbers are 71 and 73 such that their sum is 144.

Continually following one another in a regular counting order or in the order of smallest to greatest are numbers known as consecutive numbers.

Let first odd number is x

then second consecutive odd number will be x+2

Given that the sum is 144

So,

x+(x+2)=144

On solving and adding like terms

2x+2=144

On subtracting 2 both sides

2x+2-2=144-2

2x=142

On dividing 2 both sides

x=142/2

Answers:

a. The company needs to sell 100 units to reach the maxmum profit.

b. The company's maximum profit is $5,000.

Solution:

a. How many unit does the company need to sell to reach the maximum profit?

p(x)=-0.5x^2+100x

This is a quadratic equation, and its graph is a parabola vertical (because the veriable "x" is square). Comparing with the general form:

p(x)=ax^2+bx+c; a=-0.5, b=100, c=0

a=-0.5<0 (negative), then the parabola opens downward, and it has a maximimun value (maximum profit) at its vertex.

We can find the abscissa of the vertex (units that the company needs to sell to reach the maximum profit using the following formula:

x=-b/(2a)

Replacing b by 100 and a by -0.5 in the formula above:

x=-100/[2(-0.5)]

x=-100/(-1)

x=100

The company needs to sell 100 units to reach the maximum profit.

b. What's the company's maximum profit?  

To determine the maximum profit we substitute the value of "x" obrained in part "a" in the quadratic equation:

x=100→p(100)=-0.5(100)^2+100(100)

p(100)=-0.5(10,000)+10,000

p(100)=-5,000+10,000

p(100)=5,000

The company's maximum profit is $5,000.

If you cancel out the denominators by multiplying both sides by the bottom, you can then factor to find X= a / (a-b)

To solve the equation 5a/x = 5b/(x-1) for x, multiply both sides of the equation by x(x-1) to clear the fractions. Simplify and solve for x by isolating it on one side of the equation.

To solve the equation 5a/x = 5b/(x-1) for x, we need to clear the fractions by multiplying both sides of the equation by the common denominator, x(x-1). This gives us 5a(x-1) = 5bx. Expanding the equation, we get 5ax - 5a = 5bx. Rearranging the terms, we have 5ax - 5bx = 5a. Factoring out x, we get x(5a-5b) = 5a. Finally, dividing both sides by (5a-5b), we can solve for x as x = 5a/(5a-5b).
