The solution to the system of equation 4g - 2h = -4 and 17 = h - 5g is g = -5 and h = -8
What is an equation?An equation shows how two or more numbers and variables are related to each other.
The standard linear equation is:
y = mx + b
Where m is the rate of change and b is the y intercept
Given the equation:
4g - 2h = -4 (1)
Also:
17 = h - 5g
multiplying through by 2:
-10g + 2h = 34 (2)
Solving by elimination method. Add equation 2 and 1:
-6g = 30
g = -5
Put g = -5 in eqn 1:
4(-5) - 2h = -4
-20 - 2h = -4

What is the least common denominator of the rational expressions below? 1/2x^2+8x + 10/x^2
The least common denominator of the given rational expressions is 2x^3(x + 4). This is the smallest expression that both denominators can be multiplied by to obtain equivalent fractions with a common denominator.
To find the least common denominator (LCD) of the rational expressions 1/(2x^2 + 8x)and 10/x^2, we need to determine the common factors in the denominators and then multiply them.
The first denominator, 2x^2 + 8x, can be factored as 2x(x + 4), where x + 4 is a linear factor.
The second denominator,[tex]x^2[/tex], is already in its factored form.
To find the LCD, we need to consider all the factors and their highest powers. In this case, we have:
2x(x + 4) and [tex]x^2[/tex]
Since the highest power of x in 2x(x + 4) is 1 and in [tex]x^2[/tex] is 2, the LCD must include both factors with their highest powers. Therefore, the LCD is:
LCD = 2x(x + 4)(x^2)
Simplifying further, we can write the LCD as:
LCD = 2x^3(x + 4)
So, the least common denominator of the given rational expressions is 2x^3(x + 4). This is the smallest expression that both denominators can be multiplied by to obtain equivalent fractions with a common denominator.
Using the LCD, we can then add or subtract the rational expressions by multiplying each term by the necessary factors to achieve the common denominator.

Dana reflects point A(2,5) across line ℓ to get image point A′(6,1). What is an equation for line ℓ?
The required equation of line ℓ is y = x + 3.
The slope of the line of reflection is the negative reciprocal of the slope of the line connecting the original point and the image point.
To find the slope of the line connecting A and A', we can use the slope-intercept form of a line:
y = mx + b
where m is the slope and b is the y-intercept.
To find the slope, we can use the difference of y-coordinates over the difference of x-coordinates, or
m = (1-5)/(6-2) = -4/4 = -1
The slope of the line connecting A and A' is -1
Since the line of reflection has a negative reciprocal slope, its slope is 1
Now we can use a point on the line of reflection and the slope to find its equation.
We know that point A(2,5) is on the line of reflection
We can use the point-slope form of a line:
[tex]y - y_1 = m(x-x_1)[/tex]
y - 5 = 1(x - 2)
y = x + 3
So, the equation of line ℓ is y = x + 3.

How do you find the coordinates of two points given an equation?
To find the coordinates of two points given an equation, you can substitute different values of x into the equation and solve for y, or by using the symmetry property of the equation.
The first method to find the coordinates of two points is to substitute different values of x into the equation and solve for y. Once you have the coordinates of the two points, you can use them to graph the equation and further analyze the function.
For example, if the equation is y = 2x + 1, you can substitute x = 0 and x = 1 into the equation to find the coordinates of the two points. Substituting x = 0 gives y = 2(0) + 1 = 1, so the first point is (0,1). Substituting x = 1 gives y = 2(1) + 1 = 3, so the second point is (1,3).
Another way to find the coordinates of two points is by using the symmetry property of the equation. For example, if the equation is y = -x^2 + 4x -3, you can substitute x = -1 and x = 1 into the equation and solve for y.
In conclusion, finding the coordinates of two points given an equation involves substituting different values of x into the equation and solving for y, or by using the symmetry property of the equation.

The zero of the polynomial 3x³ 4x² 7 is -7/3.
In order to find the zeros of a polynomial, one must first factor the equation and then set it equal to zero. The zeros of a polynomial are the values of x that make the equation equal to zero. The zeros of a polynomial can be found by factoring the polynomial and then solving for x, which will produce the x values that make the equation equal to zero.

A particle moves along the x-axis with position function x ( t ) = 4 sin ( (π − t) / 2 ) for 0 ≤ t ≤ 4 π where t is measured in seconds. For what values of t does the particle have an acceleration of 0?
When t = π and t = 3π, the acceleration of a particle moving along the x axis with position function x ( t ) = 4 sin ( (π − t) / 2 ) for 0 ≤ t ≤ 4 π where t is measured in seconds is zero.
An acceleration of 0 means that the velocity of the particle is constant, so the derivative of the velocity function is 0. Therefore, the particle has an acceleration of 0 when the second derivative of the position function is 0.
The position function is
x(t) = 4 sin((π − t) / 2)
so the velocity function is
x'(t) = -2cos((π − t) / 2)
and the acceleration function is
x''(t) = - sin((π − t) / 2).
To find when x''(t) = 0, we set -sin((π − t) / 2) = 0 and solve for t:
- sin((π − t) / 2) = 0
sin((π − t) / 2) = 0
(π − t) / 2 = nπ, where n is an integer
t = π - 2nπ
So the particle has an acceleration of 0 when t = π - 2nπ, where n is an integer.
As t is in the interval 0 ≤ t ≤ 4π, the possible values of t is π and 3π.

Name an angle bisector
Down Below
Step-by-step explanation:Angle bisector
An angle bisector is a line segment, ray, or line that divides an angle into two congruent adjacent angles.
Line segment OC bisects angle AOB above. So, ∠AOC = ∠BOC which means ∠AOC and ∠BOC are congruent angles.
Bisecting an angle with compass and ruler
In geometry, it is possible to bisect an angle using only a compass and ruler. To do so, use the following steps:
Place the point of the compass on vertex, O, and draw an arc of a circle such that the arc intersects both sides of the angle at points D and E, as shown in the above figure.Draw two separate arcs of equal radius using both points D and E as centers. Make sure the radius is long enough so the arcs of the two circles can intersect at point F.Use a ruler to draw a straight ray from O to F. OF bisects the angle AOB.Things to know about an angle bisector
If a point lies anywhere on an angle bisector, it is equidistant from the 2 sides of the bisected angle; this will be referred to as the equidistance theorem of angle bisectors, or equidistance theorem, for short.
In the figure above, point D lies on bisector BD of angle ABC. The distance from point D to the 2 sides forming angle ABC are equal. So, DC and DA have equal measures.
Conversely, if a point on a line or ray that divides an angle is equidistant from the sides of the angle, the line or ray must be an angle bisector for the angle.
Based on the equidistance theorem, it can be seen that when the two sides that make up an angle are tangent to a circle, the line segment or ray formed by the angle's vertex and the circle's center is the angle's bisector.
In the diagram above, the two sides of the angle are tangent to the circle and, DC and DA are the distances from the center of the circle to the sides. DC and DA are also the radii of the circle. Since all radii of a circle have equal measure, line BD bisects the angle.
Angle bisector theorem
For a triangle, like the one in the diagram below, if the bisector of angle A intersects side BC at point D, the ratio of the lengths of AB to AC equals the ratio of the length BD to DC. This can be written as: [tex]\frac{AB}{AC}=\frac{BD}{DC}[/tex]
The point at which the three interior angle bisectors intersect is known as the incenter of the triangle. Referencing the diagram below, the three bisecting rays intersect at point D. Point D is the incenter of the triangle and is a point that is equidistant from the three sides of the triangle.

What is a fraction?A fraction can be described as one part of a whole number, element or variable.
In mathematics, there are different types of fractions which includes;
Complex fractionsSimple fractionsImproper fractionsProper fractionsMixed fractionsFrom the information given, we have the fractions;
1/(x -3)² - 2/x² - 9 + 1/(x+3)²
Note that with the knowledge of difference of two squares;
x² - 9 is equivalent to (x+3)(x-3) = (x-3)²
Now, let's take the lowest common multiple
(x+3)² -2(x+3)(x-3) +(x-3)²/ (x+3)²(x-3)²
expand the bracket
x²+3x+3x+9 -2x² -6x +6x +9 + x² -3x -3x - 9/ (x+3)²(x-3)²
Add like terms
9/(x+3)²(x-3)²
Hence, the value is 9/(x+3)²(x-3)²
