Inequalities are expressions that refer to non-equivalent quantities. Inequalities can express less than, more than, less than or equal to, more than or equal to.
The type of inequalities and symbols are:
\(<,>,\leq,\ge\)So, there are four types of inequalities, for example:
\(\begin{gathered} x<2 \\ x>2 \\ x\leq2 \\ x\ge2 \end{gathered}\)Each inequality is different from the other, this means that the symbol used represents a type of inequality.
At last, among the choices, the inequalities are
\(\begin{gathered} x<0 \\ 3x+5x>11 \\ y+5\leq11 \\ 7-1>-32 \end{gathered}\)However, variable inequalities mean that the inequalities must have a variable in it. So, they are:
\(\begin{gathered} x<0 \\ 3x+5x>11 \\ y+5\leq11 \end{gathered}\)Therefore, the variable inequalities are b, c, and d.

Which of the follow is the equation of a line perpendicular to y=2x-5 that passes through the point (2, -5)?
Answer:
\(D) y=-\frac{1}{2} x-4\)
Step-by-step explanation:
Perpendicular means the slope of the other line is the negative reciprocal.
Slope in y = 2x - 5 is 2.
Negative reciprocal of 2 is - 1/2 or - 0.5
y = - 0.5x + b
Substitute.
- 5 = - 0.5(2) + b
- 5 = - 1 + b
b = - 4
y = - 0.5x - 4

Based on these results, express the probability that an eighth grader chosen at

Percent to the nearest whole number = 7%
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
Probability = (Number of possible outcomes)/(Total number of outcomes)
Total number of outcomes = 2 + 15 + 2 + 11 = 30
Number of possible outcomes = 2
Probability = 2/30 = 1/15 = 0.0666
Percent to the nearest whole number = 0.0666 *100 = 7%

Three quarters of a number is 27. What is two ninths of the number?
Answer:
8
Step-by-step explanation:
let x be the number , then
\(\frac{3}{4}\) x = 27 ( multiply both sides by 4 to clear the fraction )
3x = 108 ( divide both sides by 3 )
x = 36
the number is 36, so
\(\frac{2}{9}\) × 36 = 2 × 4 = 8
The two ninths of the number is 8
We know that Three quarters of a number is \(\frac{3}{4}\) times of a number
Hence we will assume the number x ,
\(\frac{3}{4} of x = 27\)
\(x = 27 X \frac{4}{3}\)
\(x = 36\)
Now as we know the number is 36
Therefore , the two ninths of the number assumed as y
We will multiply the number 36 by 2 and then divide by 9
Hence,
\(y = 36 X \frac{2}{9}\)
\(y = 8\)
Thus, the two ninths of the number 36 is 8

The general form of the equation of a circle is a X squared plus BY squared plus 3X plus 3Y plus Z equals zero wear a equals B does not equal zero is the circle has a radius of three units in the center lies on the Y axis, which set of values of a B C,D and E my correspond to the circle
The set of values that corresponds to the circle with a radius of three units and the center lying on the Y axis is:
A = 1, B = 1, C = 0, D = 3, E = 0.
The general equation of a circle is given by:
x^2 + y^2 + 2gx + 2fy + c = 0
In this case, since the circle has a radius of three units and the center lies on the Y axis, we can deduce the following information:
The center of the circle lies on the Y axis, which means the x-coordinate of the center is zero.
The radius of the circle is three units, which means the distance from the center to any point on the circle is three units.
Using the information above, we can substitute the values into the general equation to solve for the corresponding values:
Substituting the x-coordinate of the center (zero) into the equation, we have:
0^2 + y^2 + 2g(0) + 2fy + c = 0
y^2 + 2fy + c = 0
Since the center lies on the Y axis, the x-coordinate is zero, so the term with x (2gx) becomes zero.
Substituting the radius of the circle (three) into the equation, we have:
(3)^2 = 9
Therefore, the equation becomes:
y^2 + 2fy + c = 9
Comparing this equation with the general form of the circle equation, we can deduce the values of A, B, C, D, and E as follows:
A = 1 (coefficient of x^2)
B = 1 (coefficient of y^2)
C = 0 (constant term)
D = 3 (coefficient of x)
E = 0 (coefficient of y)
Hence, the set of values that corresponds to the circle is A = 1, B = 1, C = 0, D = 3, and E = 0.

Given are two right triangles we need to find the missing sides,
We will use Trigonometric ratios to find the same.
We know that,
Sin a = perpendicular / hypotenuse
Cos a = base / hypotenuse
Tan a = perpendicular / base
1) Sin 60° = x / 4√3
x = √3/2 × 4√3
x = 6
Cos 60° = y / 4√3
1/2 × 4√3 = y
y = 2√3
2) Cos 60° = x / 98
x = 1/2 × 98
x = 49
Sin 60° = y / 98
√3/2 = y / 98
y = 49√3
Hence the values are 1) x = 6, y = 2√3 and 2) x = 49, y = 49√3.

Answer:
4 times
Step-by-step explanation:
The area of a circle is given by the formula A = πr², where "r" is the radius of the circle.
Let's calculate the areas of the two circles:
For the circle with a radius of 4 inches:
=> A₁ = π(4)² = 16π in²
For the circle with a radius of 2 inches:
=> A₂ = π(2)² = 4π in²
To find the ratio of the areas, we divide the area of the circle with a radius of 4 inches by the area of the circle with a radius of 2 inches:
=> A₁/A₂ = (16π) / (4π) = 4
Therefore, the area of a circle with a radius of 4 inches is 4 times greater than the area of a circle with a radius of 2 inches.

X = [?]°
Hint: Sum = (n-2)180
Answer:
120°
Step-by-step explanation:
Sum of angles = (n-2)180°, where n is the number of sides.
This is a hexagon, so n=6.
Sum of angles = (6-2)180° = 720°
Each interior angle = 720°/6 = 120°
Which equation represents a line which is parallel to the y-axis?
X=-4y
Y=x-3
Y=-7
X=-8
Answer:
x = -8
Step-by-step explanation:
If the line is parallel to the y axis, that means it will be a vertical line.
Vertical lines have an equation of x = , because the line will only go through one x value.
They also will not have a slope, because their slope is undefined.
So, the correct answer is x = -8
