Well, that cross you see on the graph are your X and Y lines.
X line is flat on its side, Y line goes up to the sky!
-2x - 2 are what you need most to start graphing. Ignore y> for now.
-2x tells you your slope, or how steep your line is. And whether your line will shoot up, or go down.
Since its NEGATIVE ( - 2 x) your line will most definetely be going DOWN.
2x tells you your slope. Or how steep the line will be.
But FIRST, you need to know where your line begins.
thats what -2 is for.
See those little numbers on Y line?
Look for -2 on the line.
Thats where your line begins.
Make a little dot there.
Now -2x tells you the slope of the line, or how steep it is.
Take the -2.
Put a 1 under it for no reason. You will do this every single time in the future.
Now you Have
-2 / 1
That tells you the slope.
Since the line is NEGATIVE:
You go DOWN 2, and RIGHT 1.
To sketch the graph of the inequality y > -2x - 2, draw a dashed line for y = -2x - 2 and shade the area above this line, as this area represents the solution set of the inequality.
Explanation:To sketch the graph of the linear inequality y > -2x - 2, you would begin by drawing the line y = -2x - 2 as if it were an equation. This line serves as the boundary between the solutions of the inequality and the non-solutions. Since the inequality is greater than, not greater than or equal to, you'll use a dashed line to indicate that points on the line are not included in the solution set.
Next, since the inequality is y > -2x - 2, you will shade the area above the line to indicate that all the points in this area satisfy the inequality. That shaded region represents all the possible solutions to the inequality. Always remember when graphing inequalities to pick a point, often(0,0) if it's not on the line, and check if it satisfies the inequality to ensure correct shading area.

What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given,
Length of rope = 6 meter
Length of section = 1.4 meter
Number of sections = Length of rope ÷ Length of section
Number of sections = 6/1.4 = 4.28 since 0.28 part is not complete section so we will not consider it.

The graph shows how the distance an object traveled changed over time.
Between which two points was the object traveling at the greatest speed?
A.
between points C and D because that slope is the steepest
B.
between points A and B because that segment is the longest
C.
between points B and C because that segment is horizontal
D.
between points A and B because that slope is the steepest
Answers
The two points which shows the object traveling at the greatest speed is D. between points A and B because that slope is the steepest
How does this section show the greatest speed ?
The segment between points A and B has the steepest slope, indicating a rapid change in distance over a short period, which implies a higher speed.
This makes sense given the concept of the physics of motion, where a steeper slope on a distance-time graph represents a higher velocity or speed.
Between points C and D has the second greatest speed because it shows that as time went, distance was covered unlike between points B and C.

What is the area of this face ?
Answers
Answer: The area of the face is 15 sq. in.
Step-by-step explanation: We are given to find the area of the yellow-coloured face in the figure.
The area of the coloured face is equal to the area of one face of a cube of side 4 in MINUS the area of one face of a cube of side 1 inch.
The area of one face of a cube of side 4 in is given by
[tex]A=\textup{area of a square of side length 4 in.}=4\times 4=16\textup{ sq. in.}[/tex]
and the area one face of a cube of side 1 in is given by
[tex]a=\textup{area of a square of side length 1 in.}=1\times 1=1\textup{ sq. in.}[/tex]
Therefore, the area of the coloured face will be
[tex]Area=A-a=16-1=15\textup{ sq. in.}[/tex]
Thus, the area of the face is 15 sq. in.
The area of the face which is indicated in the figure is 15 in².
Use the concept of quadrilateral defined as:
Convex and concave are the two main forms. Convex quadrilaterals can also be divided into a number of subgroups, including trapezoids, parallelograms, rectangles, rhombus, and squares.
For big cube:
length of sides = 4 in
Area of one face = 4x4 in²
Area of one face = 16 in²
For small cube:
length of sides = 1 in
Area of one face = 1x1 in²
Area of one face = 1 in²
Since we can see that
The area of one face of a small cube coincides with the face of the big cube.
Therefore,
We have to remove the area of one face of the small cube from the big cube,
So, the area of the face indicated in the figure is,
(16 - 1) in² = 15 in²
Hence,
The area of the required face is 15 in²

Given that there are:-
6 girls
4 boys
Probability of 1 girl being chosen: 1/6
Probability of 1 boy being chosen: 1/4
Probability of another boy being chosen: 1/3
1/6 = 0.17 x 100% = 17%
1/4 = 0.25 x 100% = 25%
1/3 = 0.33 x 100% = 33%

Given that segments RS and RT are tangent to circle Q, find the length of RS.
Answers
As they both are tangents of the same circle, their lengths must be equal.
RS = RT
x/4 = x-6.3
x = 4x - 25.2
4x-x = 25.2
3x = 25.2
x = 8.4
As, RS = x/4, it will be equal to 8.4/4 = 2.1
SO, YOUR FINAL ANSWER IS RS = 2.1
To find the length of segment RS, we can use the tangent-radius theorem and the Pythagorean theorem. Segment RS is perpendicular to the radius of circle Q that passes through point S. By using the Pythagorean theorem, we can solve for the length of RS.
Explanation:The length of segment RS can be found using the tangent-radius theorem. According to this theorem, if a line is tangent to a circle at a certain point, then the line is perpendicular to the radius that passes through that point. Therefore, segment RS is perpendicular to the radius of circle Q that passes through point S.
Since RS is perpendicular to the radius, RS and the radius form a right triangle. The length of RS can be found using the Pythagorean theorem. Let's denote the length of the radius as r and the length of RS as x. The radius is the hypotenuse of the right triangle, so we have:
x^2 + RS^2 = r^2
Since RS is the only unknown, we can solve for it. Once we have the value of the radius, we can substitute it into the equation to find the length of RS.

Translate the following statement into an inequality: Five less than a number is at least nine.
Answers
The given statement translates to the inequality x - 5 ≥ 9.
To do this, we first need to interpret ‘a number’ as a variable, which we can call x. ‘Five less than a number’ means we subtract five from our variable, expressed as x - 5. ‘At least nine’ indicates that the value should be greater than or equal to nine, which in inequality form is ( ≥ 9 ). Therefore, the complete inequality that represents the given statement is x - 5 ≥ 9.

Calculate the length of the circumference of a circle with diameter 6.2cm use pi = 3
Answers
The circumference of the circle with diameter 6.2 cm, using (pi) equal to 3, is calculated as 18.6 cm using the formula C = (pi)d.
The question asks to calculate the length of the circumference of a circle with a diameter of 6.2 cm, using an approximate value for (pi) as 3. To find the circumference of a circle, the formula C = (pi)d is used, where C is the circumference and d is the diameter. Since we are provided with the diameter (6.2 cm) and an approximate value for
(pi) as 3, the calculation is straightforward.
Using the formula,
C = (pi)dC = 3 * 6.2 cmC = 18.6 cmThus, the circumference of the circle is 18.6 cm.

The circumference of the circle with a diameter of inch is 3.14 inch.
Explanation:The circumference of a circle can be found by multiplying its diameter by π (pi). In this case, the diameter of the circle is given as inch. To find the circumference, we need to multiply the diameter by π.
Circumference = Diameter × π
Since the diameter is inch, the circumference of the circle is ( inch) × π = inch × π = 3.14 inch.
