The value for the expression 6 + 9w - 5s is 59.
How do you locate the algebraic expression?You must substitute a number for each variable and carry out the arithmetic procedures to evaluate an algebraic expression. Since 6 + 6 equals 12, the variable x in the case above equals 6. If we are aware of the values of our variables, we can replace the variables with those values before evaluating the expression.
When the variables and constants of an expression are given values, the outcome of the computation it describes yields the expression's value. The quantity that the function assumes for these argument values is the value of the function, given the value(s) assigned to its argument(s).
The expression 6 + 9w - 5s when w = 7 and s = 2.
6 +(9*7 - 5*2) = 6+63 - 10 = 59.

How do you plot a negative graph?
Negative numbers are to the left of the origin on the x-axis and below the origin on the y-axis. To graph with negative numbers, start at the origin and go to the left if the x-value is negative, and downward if the y-coordinate is negative.
Now, According to the question:
Graph with Negative Numbers:
Graphing with negative numbers follows the same process as graphing with positive numbers, but the points will lay in quadrants II, III, and IV. Negative numbers are to the left of the origin on the x-axis and below the origin on the y-axis. To graph with negative numbers, start at the origin and go to the left if the x-value is negative, and downward if the y-coordinate is negative. Points in quadrant I will always follow the format (+, +). Points in quadrant II will be (-, +), points in quadrant III will be (-, -), and points in quadrant IV will be (+, -).

What is the formula of parabola graph?
The standard form of the equation of a parabola is y = ax² + bx + c, where 'a', 'b' and 'c' are constants.
A parabola is a type of curve in mathematics, and it is defined by an equation of the form y = ax² + bx + c. Here, a, b, and c are constants and x is a variable. The graph of this equation is a U-shaped curve, which is symmetrical about the line x = -b/(2a). The curve has exactly one point of inflection, located at -b/(2a), and the curve opens either up or down depending on the value of a. The vertex of the parabola also occurs at the point -b/(2a). Parabolas are used to describe a wide range of phenomena, including projectile motion and the trajectory of satellites in space. They are also used in optics, engineering, and other sciences.

What is a proportional relationship?In Mathematics, a proportional relationship is a type of relationship that generates equivalent ratios and it can be modeled or represented by the following mathematical expression:
y = kx
Where:
k is the constant of proportionality.y and x represent the variables in a proportional relationship.Next, we would determine the constant of proportionality (k) for the data points on this graph as follows:
Constant of proportionality, k = y/x
Constant of proportionality, k = 31.60/4
Constant of proportionality, k = 7.9
When the value x = 2, the value of A can be calculated as follows;
y = kx
A = 7.9 × 2
A = 15.80
When the value y = 39.50, the value of B can be calculated as follows;
x = k/y
B = 39.50/7.9
B = 5.
When the value x = 8, the value of C can be calculated as follows;

What is the distance of point A (- 5/6 from the origin?
The distance between the point (-5, 6) to the origin is 61 units.
What do we mean by distance?Regardless of direction, an object's distance is defined by its total velocity.
Distance is the amount of space an object has traveled, regardless of where it began or concluded.
Knowing an object's distance from us allows us to determine its true size.
The following formula is widely used to determine the distance between two points: d=((x2 - x1)2 + (y2 - y1)2)
The given point is thus:
(-5, 6)
Assume that (0, 0) serves as the origin and that the given position is at (-5, 6).
d=((-5 - x1)2 + (6 - y1)2)
d=((-5)2 + (6)2)
d=25+36
d=61 units
Therefore, the distance between the point (-5, 6) to the origin is 61 units.

Are these ratios equivalent 40/18 and 27/11
The ratios 40/18 and 27/11 are not equal because 20/9 and 3/1 are different fractions. They stand for various proportional connections between two quantities, in other words.
Why are there ratios not equivalent?We need to see if the ratios of 40/18 and 27/11 fall to the same fraction when the numerator and denominator are both divided by their largest common factor (GCF).
Given that the GCF of 40 and 18 is 2, we can obtain 20/9 by reducing both the numerator and denominator of 40/18 by 2. Since the GCF of 27 and 11 is also 11, we obtain 3/1 when we divide the numerator and denominator of 27/11 by 11.

The measurements in (a) 3 inch, 5 inch, 7 inch produce a triangle. Other two measurements do not produce a triangle.
What is triangle and what their properties are?A triangle is a three-sided polygon that consists of three edges and three vertices.
The properties of the triangle are:
The sum of all the angles of a triangle (of all types) is equal to 180°.The sum of the length of the two sides of a triangle is greater than the length of the third side.Using second properties we find that which of the following measures produce a triangle.
In a) 3 inch, 5 inch, 7 inch, the sum of the length of two smallest sides are
3 + 5 = 8 inch, which is greatest from the third side.
So this measures produce a triangle because the sum of the length of the two sides of a triangle is greater than the length of the third side.
In b) 5cm, 7cm, 13 cm, the sum of the length of two smallest sides are
5 + 7 = 12 cm, which is smallest from the third side
So this measures does not produce a triangle because the sum of the length of the two sides of a triangle is smaller than the length of the third side.
In c) 14.23ft, 18.23ft, 36.23ft, the sum of the length of two smallest sides are
14.23 + 18.23 = 32.46ft, which is smallest from the third side.

So, if the radius of the sphere is y.
Then the volume of the sphere,
V₁ = 4/3πy³.
So, if the radius of the sphere is 2y.
Then the volume of the sphere with the radius 2y,
V₂ = 4/3π(2y)³.
= 8(4/3)π(y)³.

The law of cosines, commonly referred to as the cosine rule or the cosine formula, in trigonometry essentially connects the length of the triangle to the cosines of one of its angles.
Law of Cosines: c² = a² + b² - 2ab cos C
We are given a= 37, b=23 and x= 20
Using the law of cosines,
⇒x² = a² + b² - 2ab cos x
