Can someone explain multiplicity of a zero?

[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.

There are 13 rungs on the ladder :)

Answer:

23 rungs

Step-by-step explanation:

Let the number of rungs on the ladder be h and make the necessary adjustments based on this

Given that she is on the middle rung of a ladder this is equivalent to

= (h + 1)/2

She climbed up three rungs

= (h + 1)/2 + 3

moved down five rungs

= (h + 1)/2 + 3 - 5

and then climbed up 7 rungs

=  (h + 1)/2 + 3 - 5 + 7

Then she climbed up the remaining 6 rungs to the top of the ladder

(h + 1)/2 + 3 - 5 + 7 + 6 = h

(h + 1)/2 + 11 = h

h + 1 + 22 = 2h

2h - h = 23

h = 23

Let P = Pecan trees and H = Hazelnut trees.

Multiply the number of acres of each by the number of pounds of each acre:

45 pounds per acre of Pecan trees would be 45p

25 pounds per acre of hazelnut trees would be 25h

You would then add those together to get the total pounds of nuts:

45p + 25h = 900

The answer would be D, 45p + 25h = 900

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:

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.

Using the concept of scale, we find that the distance between Cleveland and Cincinnati on the first map (1 cm to 10 km) is 40 cm, equivalent to 400 km in real-world distance. On the second map with a scale of 1 cm to 50 km, the equivalent distance is calculated to be 8 cm.

To calculate the distance between Cleveland and Cincinnati on the second map, we use the concept of scale. On the first map, the scale is 1 cm to 10 km, and the distance is represented as 40 cm. Scaling this to the real-world distance gives us 40 cm × 10 km/cm = 400 km between the two cities.

Now, let's apply the second map's scale of 1 cm to 50 km. To find the corresponding map distance, we set up a proportion: 10 km/cm (first map) / 50 km/cm (second map) = 40 cm (distance on the first map) / X cm (distance on the second map). Simplifying this, we find that X = 40 cm ×(10 km/cm) / (50 km/cm) = 40 cm × 1/5 = 8 cm.

Therefore, the distance between Cleveland and Cincinnati on the second map, which has a scale of 1 cm to 50 km, would be 8 cm.

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).

The value of f in the equation 6f − 12 = −4f + 6 is 1 4/5.

To answer the student's question, we need to solve the algebraic equation 6f − 12 = −4f + 6 for the unknown variable f. First, we want to get all terms with f on one side of the equation, and all constant terms on the other side. Thus, we'll add 4f to each side of the equation to eliminate -4f from the right side of the equation and get 6f + 4f = 6 + 12. This simplifies to 10f = 18, then we divide each side by 10, and we get f = 18/10 which reduces to f = 1 4/5 (Option C).

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.
