Answer: x = 1

Step-by-step explanation:

Simplifying

-4(-6x + 3) = 12

Reorder the terms:

-4(3 + -6x) = 12

(3 * -4 + -6x * -4) = 12

(-12 + 24x) = 12

Solving

-12 + 24x = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '12' to each side of the equation.

-12 + 12 + 24x = 12 + 12

Combine like terms: -12 + 12 = 0

0 + 24x = 12 + 12

24x = 12 + 12

Combine like terms: 12 + 12 = 24

24x = 24

Divide each side by '24'.

x = 1

Simplifying

x = 1

Answer: (-3, 0) and (-2, 0)

Step-by-step explanation:

1. Factor

(x+3)(x+2) = 0

2. Check if your factoring is correct

x^2 + 3x +2x + 6 = 0

x^2 + 5x + 6 = 0

3. Look back at factors and use them to find the zeros

(x+3) - > (-3, 0)

(x+2) -> (-2, 0)

Given :

The height of a building is 1417 ft.

To Find :

How long would it take an object to fall to the ground from the top.

( Use the formula s = 16t² where s is the distance, in feet traveled by an object falling freely from rest in seconds. )

Solution :

Putting value of height in given equation, we get :

[tex]16t^2 = 1417\\\\t^2 = \dfrac{1417}{16}\\\\t^2 = 88.5625\\\\t = \sqrt{88.5625}\\\\t = 9.41 \ seconds[/tex]

Therefore, time taken by object to reach the ground is 9.41 seconds.

Answer:

55%

Step-by-step explanation:

66

120

x 100% = 55%

Answer:

66 is 55% of 120

Step-by-step explanation:

66 = 120 * x%

percent just means out of 100

for example, 20% is equal to 20/100

so, x% is x/100

66 = 120 * x/100

66/[tex]\frac{x}{100}[/tex] = 120

66 * 100/x = 120

6600/x = 120

cross multiply

6600/x = 120/1

6600 * 1 = x * 120

6600/120 = x

x = 55

Answers:

x = 3

y = 9

=========================================================

Explanation:

We're told that angle A is 20x. The diagram shows we have an equilateral triangle (since all three sides are the same length), so we know that all angles are the same measure and they are equal to 60 degrees.

Equate 20x and 60. So we solve 20x = 60 and that leads to x = 3 after you divide both sides by 20.

Since we have a triangle with all sides equal, we know that AB = AC = 9, therefore y = 9 because y is the length of AB.

Step-by-step explanation:

Area of a trapezoid formula base a+base b/2*h

Base a is the top length (22.5)

Base b is the bottom length (49.9)

Add those two lengths together (22.5+49.9=72.4)

Divide that by two (72.4/2=36.2)

Then multiply that by the height (36.2*23.8=861.56)

So your area is 861.56

Answer:

Zero

Step-by-step explanation:

Average rate of change can also be called as gradient or change in the respective variable , in this case we need the average rate of change of y which has the function y = -7

Since this is a linear function and if we draw the graph of y = -7 the graph would be parallel to the x-axis, and any line parallel to the x-axis has slope of zero , hence the average rate of change of the function y = -7 is zero

Answer:A

Step-by-step explanation:

Using translation concepts, it is found that the corrects options are:

Answer:

3 kg= 14.7

6 kg= 29.4

9 kg= 44.1

Step-by-step explanation:

The gravitational potential energy of the cylinders as follows:

3 kg: 14.7 kJ, 6 kg: 29.4 kJ, and 9 kg: 44.1 kJ

GPE is gravitational potential energy, mass is the mass of the object in kilograms, gravity is the acceleration due to gravity in meters per second squared (usually taken to be 9.8 m/s²), and height is the height of the object above the reference point in meters.

To calculate the gravitational potential energy (GPE) of an object, you need to know its mass, the acceleration due to gravity, and its height above a reference point. You can use the formula:

GPE = mass × gravity × height

In this case, the mass of each cylinder is given in the first column of the chart, and the height of the cylinders is 500 meters. However, the acceleration due to gravity is not given in the chart. We can assume that it is 9.8 m/s², but if you have a different value, you should use that instead.

Using these values, we can calculate the gravitational potential energy of the 3-kilogram cylinder as follows:

GPE = 3 kg × 9.8 m/s² × 500 m = 14700 kg m/s²

Converting this to kilojoules gives us:

GPE = 14700 kgm/s² × (1 J/1 kgm/s²) = 14700 J

Converting this to kilojoules (kJ) gives us:

GPE = 14700 J / 1000 J/kJ = 14.7 kJ

Therefore, the gravitational potential energy of the 3-kilogram cylinder is 14.7 kJ.

You can use the same process to calculate the gravitational potential energy of the 6-kilogram is 29.4 kJ and the 9-kilogram cylinders is 44.1 kJ.

Answer: -1/4

Step-by-step explanation: The slope is rise over run. The ski run drops 5, so it would be -5, and the horizontal change of 20 would be the run, so you'd get -5 over 20 then you divide both by 5 and you get your answer of -1 over 4.

-1/4  is the slope of a ski run that rises 5 feet for every horizontal change of 20 feet

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Given the slope of a ski run that rises 5 feet for every horizontal change of 20 feet

So the two points are (0,5) and (20,0)

m=0-5/20-0

m=-5/20

m=-1/4

Hence -1/4  is the slope of a ski run that rises 5 feet for every horizontal change of 20 feet

Answer:

Jenna spent 7 hours babysitting.

Step-by-step explanation:

With the information provided, you can say that Jenna's total earnings are equal to the amount she earned cleaning her neighbor's basement plus the result of multiplying the charge per hour for babysitting for the number f hours, which is:

e=20+5x, where:

e represents the total earnings

x is the number of hours

Now, you can replace e with 55 that is the toal amount she earned and solve for x:

55=20+5x

55-20=5x

35=5x

x=35/5

x=7

According to this, the answer is that Jenna spent 7 hours babysitting.

C. Use a compass to draw one arc with point M at the center and intersecting point N.

Step-by-step explanation:

I took the test and got it right.

Your welcome :)

Using a compass, draw one arc with point M at the center and point N intersecting it as the first step in the typical construction of the perpendicular bisector of MN. Option C is correct.

Lines that cut through the middle of each side of a triangle and are perpendicular to the specified side are known as the perpendicular bisectors of the triangle.

The standard construction of the perpendicular bisector of MN will be,

Step 1: Sketch a line segment with any appropriate length, XY.

Step 2: Using a compass, draw arcs above and below the line segment, with X serving as the center and XY's width greater than 50%.

Step 3: Carry out Step 2 but use Y as the center. Step 4: Write "P" and "Q" next to the junction points.

Thus, using a compass, draw one arc with point M at the center and point N intersecting it as the first step in the typical construction of the perpendicular bisector of MN. Option C is correct.
