Answer:

[tex]\large\boxed{x=-4}[/tex]

Step-by-step explanation:

[tex]-4x+3=19\qquad\text{subtract 3 from both sides}\\\\-4x+3-3=19-3\\\\-4x=16\qquad\text{divide both sides by (-4)}\\\\\dfrac{-4x}{-4}=\dfrac{16}{-4}\\\\x=-4[/tex]

Step 1: Combine like terms ( 3 and 19) by subtracting 3 to both sides

-4x + (3-3) = 19 -3

-4x = 16

Step 2: Isolate x by dividing -4 to both sides

[tex]\frac{-4x}{-4} =\frac{16}{-4}[/tex]

x = -4

Graphing the linear equation -2x - 3y = -7: Identify three points satisfying the equation, such as (0, 3), (1, 1), and (2, 1). Plotting these points on the graph, connect them to depict the line representing the equation on the Cartesian plane.

To graph the linear equation -2x - 3y = -7, we can first rearrange it to solve for y:

-2x - 3y = -7

-3y = 2x - 7

[tex]\[ y = \frac{2}{3}x + \frac{7}{3} \][/tex]

Now, we can select three points to plot on the graph. For simplicity, let's choose some integer values for x to find corresponding y values:

1. When x = 0: [tex]\(y = \frac{7}{3}\)[/tex], giving the point [tex](0, \(\frac{7}{3}\))[/tex].

2. When x = 3: y = 3, giving the point (3, 3).

3. When x = -3: y = -1, giving the point (-3, -1).

Now, plot these three points on the graph and connect them to visualize the line represented by the equation.

You need to remember that the circumference of a circle can be calculated with this formula:

[tex]C=2\pi r[/tex]

Where "r" is the radius of the circle and [tex]\pi =3.14[/tex]

In this case the distance 150 feet (From the edge of the track to the center of the circle) is the radius.

Since she walks her horse 4 times around the track, you need to multiply the circumference by 4 to calculate the approximate number of feet that she and her horse will travel:

 [tex]C=4[2(3.14)(150ft)]=3,768ft[/tex]

First make a triangle by connecting the center point of the circle to one of the end points of the chord.

This will make a right triangle. The new formed line is the radius of the circle and will be the hypotenuse of the right triangle too.

Since one of the legs of the right triangle is half the chord, divide the chord in to two.

9.6 / 2 = 4.8

Now we can calculate for the hypotenuse.

Pythagorean theorem states that  a²+b² = c²

So

√2.4² + 4.8² = c

√5.76 + 23.04 = c

√28.8 = c

5.4 = c

C is the hypotenuse and the hypotenuse is known as the radius of the circle.

So the radius is 5.4

The value of x can be any number between 1.5 to 4.5. Some translations imply that 'x' is being used in scientific notation or being adjusted by standard deviations in statistical calculations. Furthermore, finding 'x' in equations could result in more than one solution.

The question is about finding the value of x, which is a mathematical variable. Without a proper equation or context, it is not possible to determine the specific value of x. However, some details were given, stating '1.5 ≤ x ≤ 4.5', meaning that the value of x can be any number between 1.5 and 4.5. Additionally, the concept of scientific notation or exponential notation appears in the data provided ('x x 10¹'). This can help express very large or small numbers in a simplified form. For instance, if 'x' is 8.4 and '10¹' indicates we have 14 placeholder zeros, the actual measurement value would be 8.4 followed by 14 digits (840,000,000,000,000).

Furthermore, the question has hints of statistics, shown when 'x' is increased and decreased by standard deviations, which are instructions to calculate different characteristic values from certain distributions (e.g., '(x + 1s)').

Remember that solving equations may result in more than one solution, pointing out the characteristic of quadratic equations that give two solutions. And finally, dividing and multiplying by powers of 10 simply means shifting decimal points right or left respectively, according to the number of zeros in the power of ten.

Let's say the first truck weighs x tons

Then, the weight of 2nd truck = x+2 tons

The weight of 3rd truck = (x + 2) + 2 = x+4 tons

The weight of 4th truck = (x + 4) + 2 = x+6 tons

Total weight of 4 trucks:

x + (x+2) + (x+4) + (x+6) = 32

which can be solved easily to give x = 5

From this triangle we know:

THE AREA:

[tex]A=80cm^2[/tex]

THE HEIGHT:

[tex]H=B+12[/tex]

We know that the area, height, and base of a triangle are related according to the following formula:

[tex]A=\frac{BH}{2} \\ \\ Substituting \ H: \\ \\ A=\frac{B(B+12)}{2} \\ \\ Substituting \ A: \\ \\  80=\frac{B(B+12)}{2} \\ \\ 2(80)=B(B+12) \\ \\ 160=B^2+12B \\ \\ B^2+12B-160=0[/tex]

Solving B by quadratic formula:

[tex]B_{12}=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ B_{12}=\frac{-12 \pm \sqrt{12^2-4(1)(-160)}}{2(1)} \\ \\ B_{12}=\frac{-12 \pm \sqrt{12^2-4(1)(-160)}}{2(1)} \\ \\ B_{1}=8 \ and \ B_{2}=-20[/tex]

Since we can’t have a negative value of the base, the correct option is:

[tex]B=8cm[/tex]

We must use the formula:

[tex]h(t)=-5.2t^2+v_{0}t+h_{0}[/tex]

Since James drops the balloon from a height of 45m, then this is the initial height, so [tex]h_{0}=45m[/tex]. Moreover, at the very instant he drops the balloon the initial velocity is zero, so [tex]v_{0}=0[/tex]. When the ballon hit the ground [tex]h(t)=0[/tex]. Therefore:

[tex]0=-5.2t^2+45[/tex]

Solving this equation:

[tex]5.2t^2=45 \\ \\ t^2=\frac{45}{5.2} \\ \\ t^2=8.653 \\ \\ t=\sqrt{8.653} \\ \\ t=2.941s[/tex]

Rounding to the nearest tenth:

[tex]\boxed{t=2.9s}[/tex]

Finally, the water balloon will hit the ground after 2.9 seconds.

We have the equation:

[tex]h(t)=-16t^2+32t+12[/tex]

But we know that this equation follows the form:

[tex]h(t)=-16t^2+v_{0}t+h_{0}[/tex]

According to this:

The height of the platform is [tex]h_{0}=12ft[/tex]

The initial velocity of the ball is [tex]v_{0}=32ft/s[/tex]

Final answer:

The length of the arc intercepted by a central angle of 80 degrees in a circle with a radius of 16 inches is approximately 22 inches to the nearest inch.

Explanation:

To find the arc length of a circle that is intercepted by a central angle of 80 degrees, we first need to know the formula for the circumference of a circle, which is 2πr.

In a full circle, which is 360 degrees, the arc length is equal to the circumference. However, because we are only dealing with an 80-degree angle, we need to find the fraction of the circumference that corresponds to this angle. The formula to calculate the arc length (As) for any given angle (Θ) in degrees is:

As = (2πr * Θ) / 360

Given a radius (r) of 16 inches, and a central angle of 80 degrees, the arc length is:

As = (2π * 16 * 80) / 360 ≈ (100.53 inches * 80) / 360 ≈ 8033.6 / 360 ≈ 22.3 inches

Therefore, to the nearest inch, the length of the arc is 22 inches.

Answer: (5x^2 + 2)(3x - 1)

I'll break it down:

You start off with 15x^3 - 5x^2 + 6x - 2

You first group the first two terms together, and then the last two pairs together: (15x^3 - 5x^2) (6x - 2)

Then you simplify (just factor out as much as you can): 5x^2(3x - 1) 2(3x - 1)

Then you take the terms that you get from doing that.

To find the First Term:

5x^2(3x - 1) 2(3x - 1)

(5x^2 + 2)

To find the Second Term:

5x^2(3x - 1) 2(3x - 1)

(3x - 1)

So your terms are (5x^2 + 2) and (3x -1)

Final Answer: (5x^2 + 2)(3x - 1)

The resulting expression will be (5x² + 2)(3x - 1). The correct answer is option A.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The grouping of the given expression will be done as:-

You start off with 15x³ - 5x²+ 6x - 2

You first group the first two terms together, and then the last two pairs together: (15x³ - 5x²) (6x - 2)

Then you simplify (just factor out as much as you can): 5x²(3x - 1) 2(3x - 1)

Then you take the terms that you get from doing that.

To find the First Term:

5x² (3x - 1) 2(3x - 1)

(5x² + 2)

To find the Second Term:

5x²(3x - 1) 2(3x - 1)

(3x - 1)

So your terms are (5x² + 2) and (3x -1)

Therefore the resulting expression will be (5x² + 2)(3x - 1)

(3x^2-4x-4)+(-12x^2+2x+11) is equivalent to expression A .

(4x^2-3x-9)+(5x^2+5x+2) is equivalent to expression C .

You combine like terms to arrive with the answer.

The answer is:

- The first operation match with the polynomial:

B.  [tex]9x^{2} -2x+2[/tex]

- The second operation match with the polynomial:

A. [tex]-9x^{2}-2x+7[/tex]

- The third operation match with the polynomial:

C. [tex]9x^{2} +2x-7[/tex]

In order to solve the given operations, we need to group the like terms.

Remember, like terms are terms that share the same variable and the same exponent.

For example:

[tex]x^{2} +2x^{2} +3x^{3} +2=3x^{2} +3x^{3} +2[/tex]

We only operate with the variables that shares the same exponent.

Also, we need to remember the distributive property:

[tex](a+b)(c+d)=ac+ad+bc+bd[/tex]

So, we are given the following polynomials:

[tex]A.9x^{2} -2x+7\\\\B. 9x^{2} -2x+2\\\\C. 9x^{2} +2x-7[/tex]

And we need to perform the following operations:

First operation,

[tex](7x^{2}-5x+3)+(2x^{2} +3x-1)=7x^{2} +2x^{2} -5x+3x+3-1\\\\7x^{2} +2x^{2} -5x+3x+3-1=9x^{2} -2x+2[/tex]

So, the first operation match with the polynomial:

B.  [tex]9x^{2} -2x+2[/tex]

Second operation,

[tex](3x^{2}-4x-4)+(-12x^{2}+2x+11)=3x^{2} -12x^{2} -4x+2x-4+11\\\\3x^{2} -12x^{2} -4x+2x-4+11=-9x^{2}-2x+7[/tex]

So, the second operation match with the polynomial:

A. [tex]-9x^{2}-2x+7[/tex]

Third operation,

[tex](4x^{2} -3x-9)+(5x^{2} +5x+2)=4x^{2}+5x^{2} -3x+5x-9+2\\\\4x^{2}+5x^{2} -3x+5x-9+2=9x^{2} +2x-7[/tex]

So, the second operation match with the polynomial:

C. [tex]9x^{2} +2x-7[/tex]
