Erik and Nita are playing a game with numbers. In the game, they each think of a random number from 0 to 20. If the difference between their two numbers is less than 10, then Erik wins. If the difference between their two numbers is greater than 10, then Nita wins. Use the information in the interactive and what you know about absolute value inequalities to better understand the game.

The inequality for Erik to win is
|x- y| ≤ 10
And for Nita to win
|x- y| ≥ 10
What is Inequality ?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Inequalities define the connection between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than. The different inequality symbols, characteristics, and methods for resolving linear inequalities in one variable and two variables will all be covered in this article along with examples.
In the problem let the number chosen by Erik and Nita be x and y respectively .
here both x,y ≤ 20
so the inequality for Erik to win is
|x- y| ≤ 10

In a geometric series, the sum of the first three terms is 14. 25 and the sum of the first four terms is 24. 375. Find the first term and the common ratio.
Answers
The first term and the common ratio in the geometric series are 3 and 3/2.
What is a geometric series?A geometric series is described as the sum of the sequence of numbers. The sum of the nth term of a geometric sequence is expressed as:
Sₙ = a (r^n – 1) / r – 1
In this case, if the sum of the first three terms is 14.25, it means:
n = 3
S₃ = 14.25
Now, substitute the value into the formula:
Sn = a (r^n – 1) / r – 1
S₃ = a (r^3 – 1) / r – 1
14.25 = a (r^3 – 1) / r – 1
And, if the sum of the first four terms is 24.375, it means:
n = 4
S₄ = 24.375
Substitute the value into the formula:
Sₙ = a (r^n – 1) / r – 1
S₄ = a (r^4 – 1) / r – 1
24.375 = a (r^4 – 1) / r – 1
Then, we now can divide both above equations:
14.25 / 24.375 = r^3 – 1 / r^4 – 1
14.25r^4 – 14.25 = 24.375r^3 – 24.375
14.25r^4 – 24.375r^3 = –24.375 + 14.25
14.25r^4 – 24.375r^3 = –10.125
14.25r^4 – 24.375r^3 + 10.125 = 0
After factorizing we get:
r = 3/2
This is the common ratio.
Now, substitute the value of r into the equation
14.25 = a (r^3 – 1) / r – 1
14.25 = a ((3/2)^3 – 1) / (3/2) – 1
14.25 = a (19/8) / 0.5
19a / 8 = 14.25 * 0.5
19a / 8 = 7.125
19a = 57
a = 57 / 19
a = 3
Thus, the first term is 3.
Hence, the first term in the geometric series is 3 and the common ratio is 3/2.

Determine whether S is a basis for P3.
S = {4t − t2, 5 + t3, 5 + 3t, −3t2 + 2t3}
Answers
No, S is not a basis for P³. In order for a set of vectors to be a basis for a vector space, the vectors must be linearly independent and span the space.
In this case, the set of vectors does not span P³ because the highest order of the polynomials in S is t³, which does not span all of P³ which contains polynomials of order up to and including t³.
Additionally, the set of vectors is not linearly independent. For instance, 4t−t²= 5+3t−2t³, which means that the two vectors are linearly dependent. Therefore, S is not a basis for P³.

x < 3 is a solution of the inequality x - 3 < 0 and x < 3 is not the solution of the inequality x + 3 < 0.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Suppose that the inequality is x - 3 < 0.
x - 3 < 0
Adding 3 on both sides of the equation,
x - 3 + 3 < 0 + 3
x < 3
x< 3 is the solution of the expression x - 3 < 0.
Consider the inequality x + 3 < 0.
x + 3 < 0
Subtracting 3 from both sides,
x + 3 - 3 < 0 - 3
x < -3
x < 3 is not the solution of the expression x + 3 < 0
Hence the expression with x < 3 as a solution is x - 3 < 0 and not as a solution is x + 3 < 0.

What is the y-intercept of a line that passes through the points (3, -3.8) and (5, -3)? (1 point)
Enter the solution in the box below.
Answers
Answer:
Step-by-step explanation:
We can solve this by either identifying the equation or by graphing. We'll try both.
Find the Equation
The slope of the line can be determined from the Rise/Run of the 2 given points:
Going from ((3,-3.8) to (5,-3):
Rise = (-3 - (-3.8) = 0.8
Run = (5 - 3) = 2
Slope = 0.8/2 or 0.4
The equation for this line is y = 0.4x + b, where b is the y-intercept.
Enter either point to find b:
y = 0.4x + b
-3 = 0.4*(5) + b for point (5,-3)
-3 = 2+b
b = -5
The equation is y = 0.4x - 5
The y=intercept is -5 (the value of b)
Graphing
See the attached graph. Mark the two points and then draw a straight line between them. The point at which the line crosses the y axis is the y-intercept (0,

The square root of 131 is approximately 11.445 It lies between the two numbers 11 and 12, specifically, it is greater than 11 and less than 12.
We know that the square root of a number is the value that, when multiplied by itself, gives that number.
For example, the square root of 121 (which is 11) is 11 because 11 x 11 = 121.
In the same way, the square root of 131 is the number that, when multiplied by itself, will give 131.

The area of triangle if sides are 9cm 12cm and 15cm is 54 square cm.
In the given question we have to find the area of triangle if sides are 9 cm 12 cm and 15 cm.
The entire area bounded by a triangle's three sides is referred to as the triangle's area. In essence, it equals half of the base times height, or A = 1/2bh. So, in order to calculate the area of a triangular polygon, we need to know its base (b) and height (h).
Area of Triangle = 1/2 bh
Area of Triangle = 1/2 9*12

What is the centroid of a triangle?
A centroid of a triangle is a point that is the arithmetic mean position of all the points of a triangle, which is the point where the three medians of the triangle intersect. The medians of a triangle divide the triangle into 6 equal areas.
We know that:
JT = x(TK),
\where J is the centroid and x is a constant.
Since J is the centroid, it divides the median TK into a ratio of 2:1, which means that TK = 2*JT.
Substituting this into the original equation gives:
JT = x(2*JT)
Solving for JT gives:
JT/JT = 2x
x = 1/2
JT = 1/2(TK),
TK = 2JT
Hence, the value of x is 1/2, and JT = 1/2(TK), TK = 2JT.

Mason bought 6 loaves of bread and 3 packages of cheese for a total of $27. The cost of a package of cheese is $1.50 more than the cost of a loaf of bread.
Let 'x' be the cost of the loaf and 'y' be the cost of cheese. Then the equations are given as,
6x + 3y = 27
2x + y = 9 ...1
y = x + 1.5 ...2
From equations 1 and 2, then we have
2x + x + 1.5 = 9
3x = 7.5
x = $2.5
Then the value of the variable 'y' is calculated as,
y = 2.5 + 1.5
y = $4
The combined cost of one loaf of bread and one package of cheese will be given as,
⇒ $4 + $2.5
⇒ $6.5
