The solutions are all the points strictly larger than 5, to represent this, we draw an open circle at x = 5, and a bold line that points to the right.
How to represent the inequality?
Here we have the inequality:
–3(2x – 5) < 5(2 – x)
First, we need to isolate x in one side of the inequality, we will get:
-6x + 15 < 10 - 5x
15 - 10 < -5x + 6x
5 < x
Then the solutions are all the points strictly larger than 5, to represent this, we draw an open circle at x = 5, and a bold line that points to the right.

Explain how to modify the graphs of f(x) and g(x) to graph the solution set to the following system of inequalities. How can the solution set be identified?
y ≤ x^2 – 3
y > –x^2 + 2
The shaded region is the solution of the given functions f(x) = x² – 3 and g(x) = –x² + 2.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The functions f(x) = x² – 3 and g(x) = –x² + 2 are shown on the graph.
Now for the point (0, 0). Then we have
0 ≤ 0² – 3
0 ≤ – 3
which is false
Then the region is opposite to the origin.
Similarly, we have
0 > 0² + 2
0 > 2
which is false

The weight of each of the two piles Tineka split the jellybeans in the sack to is 7/24 lb.
What is the weight of each pile?
Division is when two numbers are grouped into equal parts using another number. The sign used to denote division is ÷.
In order to determine the weight of each pile, divide the weight of the sack by 2.
Weight of each sack = 7/12 ÷ 2

The graph of the parent function f(x) = |x| is dashed and the graph of the transformed function g(x) = |x| + k is solid. Use the slider to change the value of k. How does changing the value of k affect the graph? Positive values of k shift the graph . Negative values of k shift the graph
Answer:
Use the slider to change the value of k.
Positive values of k shift the graph ✔ up.
Negative values of k shift the graph ✔ down
Step-by-step explanation:
Transformation involves changing the position of a function.
The true statements are:
Positive values of k shift the graph up
Negative values of k shift the graph down
The functions are given as:
The equation of g(x) implies that, f(x) is translated or shifted vertically.
The possible values of k are:
k is greater than 0 i.e. positive
k is less than 0 i.e. negative
When k is positive, then the graph of the function shifts up
If otherwise (i.e. k is negative), then the graph of function shifts down
Changing the value of k in the function g(x) = |x| + k affects the graph by shifting it vertically.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
Horizontal translation: g(x)=f(x+c).
The graph is translated as c units to the left if c>0 and c units to the right if c<0.
Vertical translation: g(x)=f(x)+k.
The graph is translated as k units upward if k>0 and k units downward if k<0.
When k is positive, the graph of g(x) is shifted upward by k units compared to the graph of f(x). This is because, for any value of x, g(x) will be greater than f(x) by k units, due to the addition of k to the absolute value of x.
Conversely, when k is negative, the graph of g(x) is shifted downward by k units compared to the graph of f(x). This is because, for any value of x, g(x) will be less than f(x) by k units, due to the subtraction of k from the absolute value of x.
Therefore, changing the value of k in g(x) = |x| + k shifts the graph vertically, either upward or downward, depending on the sign of k.

(2x y)(2x2 2xy – y2) (2x y)(4x2 2xy – y2) (2x y)(4x2 – 2xy y2) (2x y)(2x2 – 2xy y2)
The polynomial (a + b)(a² – ab + b²) is reconstructed as (2x + y)(4y² – 2xy + y²), then the correct option is C.
What is polynomial?Polynomial is an algebraic expression that consists of variables and coefficients. Variables are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Answer:x + y = 180
p + q = 180
p = x
Show that y = q
x = 180 - y
p = 180 - q
p = x
180 - q = 180 - y
-q = 180 - y - 180
-q = -y
-q/-1 = -y/-1
q = y OR y = q
x + y = p + q CHOICE B.

Hello there.
Question:What type of triangle is defined by the following set of side lengths
10, 9, 5
Answer:
Acute
Step-by-step explanation:
The triangle perimeter is the sum of the lengths of its three sides.
[tex]p=a+b+c=10+9+5=24[/tex]
The semiperimeter of the triangle is half its perimeter. The semiperimeter appears in formulas for triangles to be given a separate name. the triangle inequality, the longest side length of a triangle is less than the semi perimeter.
[tex]s=\frac{p}{2} =\frac{24}{2} =12[/tex]
using Heron's formula
Heron's formula gives the area of a triangle when the length of all three sides is known.
[tex]T=\sqrt{s(s-a)(s-b)(s-c)}[/tex]
[tex]T=\sqrt{12(12-10)(12-9)(12-5)}[/tex]
[tex]T=\sqrt{504}=22.45[/tex]

Answer:
Graph the parabola y=x2−7x+2 .
Compare the equation with y=ax2+bx+c to find the values of a , b , and c .
Here, a=1,b=−7 and c=2 .
Use the values of the coefficients to write the equation of axis of symmetry .
The graph of a quadratic equation in the form y=ax2+bx+c has as its axis of symmetry the line x=−b2a . So, the equation of the axis of symmetry of the given parabola is x=−(−7)2(1) or x=72 .
Substitute x=72 in the equation to find the y -coordinate of the vertex.
y=(72)2−7(72)+2 =494−492+2 =49 − 98 + 84 =−414
Therefore, the coordinates of the vertex are (72,−414) .
Now, substitute a few more x -values in the equation to get the corresponding y -values.
x y=x2−7x+2
