The maximum guess that could win is,
⇒ |x - 645| = 20; the maximum guess is 665.
Therefore, Option b is correct.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Since, We have given the information that the jar has to be guessed within 20
So, the total has to be equal to 20.
Hence, the equation which is the required equation to calculate the minimum and maximum number of beans that will win the contest is,
|x - 645| = 20
When we will remove the modulus we will get two values + and -
So, x = 20 + 645 = 665
And x = 20 - 645 = -625
Hence, the maximum guess is 665.
Therefore, Option b is correct.

If you are buying $48 worth of two types of lawn seed. Ryegrass lawn seed sells for $0.70 per pound and Fescue lawn seed sells for $1.15 per pound. If you bought 25 pounds of Fescue lawn seed, write a linear equation in standard to find any amount of Ryegrass lawn seed purchased. (ax + by = c)
The amount of Ryegrass lawn seed purchased is 27.5 pounds and the linear equation formed is 0.70x + 28.75 = 48.
Linear EquationThe equation whose variables have the highest power as 1 is known as a linear equation.
How to write the linear equation for the given situation?First, let us assume that the amount of Ryegrass lawn seeds purchased is x pounds.
The cost of Ryegrass lawn seeds is $0.70 per pound.
So, the cost of all the Ryegrass lawn seeds purchased is $0.70x.
The amount of Fescue lawn seeds purchased is 25 pounds.
And the cost of Fescue lawn seeds is $1.15 per pound.
So, the cost of all the Fescue lawn seeds purchased is,
= $1.15 x 25
= $28.75
And the total cost of buying the two types of lawn seeds is $48.
So, we can write the linear equation as,
0.70x + 28.75 = 48
Solving the linear equation for x, we get
0.70x = 48 - 28.75
0.70x = 19.25
x = 19.25/0.70
x = 27.5
Hence, the amount of Ryegrass lawn seed purchased is 27.5 pounds.

Katie went to buy a new tv and finds one for $550.00. In the state of Texas, there is a 6% sales tax on items. How much did Katie pay for the TV including the tax?
Answer:
583$
Step-by-step explanation:
6% is equal to 0.06, so you multiply 550 by 0.06. which equals 33. Then, because it asks for how much Katie played, including the tax and TV, you add 33 to 550.

If the point (6, 9) is on the graph of an even function, what other point must also be on the graph?
Answer:
b/c it's an even function you know that f(x) = f(-x) too so whether you put in a positive X or a negative X you get the same answer so you know.. that (-6,9) is also on the graph of this function
Step-by-step explanation:
Given that the function is even and we know that (6, 9) is on its graph, we know that (-6, 9) must also be on the graph.
Even functions:
A function f(x) is even if:
f(x) = f(-x)
Now, we know that the point (6, 9) is on the graph of our function, this means that:
f(6) = 9
And because our function is even, we must have:
f(6) = f(-6) = 9
Then the point (-6, 9) must also be on the graph of the function.

A hairdresser is deciding to open her own studio. If the hair dresser chooses Location A she will pay $1200 in rent and will earn $45 per
haircut. If she chooses Location B, she will pay $1800 in rent and will earn $60 per haircut. How many haircuts would she have to give to make
the same profit in either location?
Answer: x = Number of haircuts
Location A profit: 45x-1200
Location B profit: 60x-1800
(Lets assume that the profit is the same for each location)
45x-1200=60x-1800

Triangle XYZ is rotated to create the image triangle X'Y'Z'.
On a coordinate plane, 2 triangles are shown. The first triangle has points X (negative 2, 2), Y (1, 2), Z (0, 4). The second triangle has points X prime (2, negative 2), Y prime (negative 1, negative 1), Z prime (0, negative 4).
Which rules could describe the rotation? Select two options.
R0, 90°
R0, 180°
R0, 270°
(x, y) → (–y, x)
(x, y) → (–x, –y)
Answer:
b. e
Step-by-step explanation:
Options B and E are the correct answers.
We need to describe the transformation of triangle XYZ to triangle X'Y'Z'.
What is rotation?Rotation is the circular movement of an object around an axis of rotation.
Now, from triangle XYZ to triangle X'Y'Z' the angle of rotation is 180°.
The translation is (x, y) → (–x, –y).
Therefore, options B and E are the correct answers.
