On a piece of paper, graph y ≥ 2x – 3. Then determine which answer choice matches the graph you drew.
Answers
Answer:
Step-by-step explanation:
We are asked to graph an inequality . y≥2x - 3
The boundary line of our given inequality will be a solid line as we have greater than or equal to ≥ sign.
The boundary line of our given inequality would be .y=2x - 3
Now, we will test point (0,0) to shade in the correct region as:
0≥2(0)-3
0≥0-3
0≥-3

Part: 0/2
Part 1 of 2
Zero(s) of k:
Answers
The zeroes of the function k(x)=15x³-48x²-48x are 0, 4 and -4/5.
The function provided is a cubic polynomial.
There will be three zeroes in total for the function k(x).
K(x) = 15x³-48x²-48x
If we put x = 0,
We can see that k(x) becomes zero,
So we can say that 0 is a solutions for this function,
Now,
K(x) = x(15x²-48x-48)
Solving 15x²-48x-48 seperately using quadratic formula,
a = 15
b = -48
c = -48
x = (-b+√D)/D and (-b-√D)/D
D = b²-4ac.
D = (-48)²-4(15)(-48)
D= 5184.
√D = 72
putting all the values to find x,
x = (-(-48)+72)/30 and (-(-48)+72)/30
x = 4 and -4/5.
our function becomes,
k(x) = x(x-4)(x+4/5)
so the zeroes are 0, 4, -4/5.

Luke is driving from Hillwood to Springfield, 926 miles apart from each other. If Luke drives at a constant speed of 57 miles per hour,what equation can we make to find out how much time will like take to get to Springfield? Represent the time in hours as the variable x.
Answers
The equation that calculates the time taken to get to Springfield is x = 926/57
What is rate?Rate is used to establish the relationship between two quantities of different units. one of the quantity is usually expressed to unity in order to estimate the change in the other quantity.
If Hillwood and Springfield are 926 mile apart, and the speed taken to get to Springfield is 57miles per hour.
Let the time taken to get to Spring field be x.
Then if 57 miles is covered in an hour and it takes x hours to get to the destination
It means total distance covered is 57 × x
This distance is equal to the distance from Hillwood to Springfield which is 926 miles.
Equating both equations.
57x = 926
In conclusion, 57x = 926 is the equation that can be used to find out the time taken.

A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 3ft and a diameter of 8ft. The tank will be made from metal (including its top and bottom). If the metal costs $29 for each square foot, how much will the metal cost in total?
Answers
The total cost of the metal needed to cover the tank shaped like a metal is $5,099.36.
What is the total cost?In order to determine the total metal cost, we are to first calculate the total surface area of the tank. Since the tank is a closed cylinder, we are to determine the total surface area of a cylinder.
The total surface area of a closed cylinder can be determined by adding the area of all its faces.
Total surface area of the closed cylinder = 2πr(r + h)
Where:
r = radius = diameter / 2 = 8/2 = 4ft
h = height
π = pi = 3.14
(2 x 3.14 x 4)(4 + 3)
25.12 x 7 = 175.84 ft²
Total cost of the metal = $29 x 175.84 = $5,099.36

which point most closely approximates the difference of B and A, that is (B -A) ?
Answers
Point (C) C closely approximates the given mathematical operation that is the difference between B and A (B - A).
What are mathematical operations?An operation, also known as an "operand" or "argument," is a function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the operations that are most frequently studied. A constant is an operation of arity zero, also known as a nullary operation. An example of an operation of arity 3, also known as a ternary operation, is the mixed product.So, when we add up 2 numbers let's say A and B, the result is always a 3rd number which is C.
A + B = CSimilarly, when we subtract a number from another number (B - A), the result is always a third number C.
B - A = CSo, (C) C closely approximates the difference between B and A (B - A).
Therefore, point (C) C closely approximates the given mathematical operation that is the difference between B and A (B - A).

Answers
The members and non-members who pay the equal cost after 5 visits for the local zoo.
What is defined as the term equations?When one variable is determined to be equal to the other, the equation formula method is used to calculate the value of the a second variable.This second variable's value is the value that the others have same value.For the given question;
The cost of membership of local zoo is $135 for members.
The parking cost is $3 for members.
Non-member admission cost is $25 for the zoo and $5 for the parking.
Let the number of number of visits paid the same amount be 'x'.
Then, the equation becomes.
Members: m = 135 + 3x
Non-Members: n = 25x + 5x
As, members and non-members are equal.
m = n
Put the values;
135 + 3x = 25x + 5x
135 + 3x = 30x
27x = 135
x = 5
Thus, members and non-members who pay the equal cost after 5 visits.

A local hamburger shop sold a combined total of 449 hamburgers and cheeseburgers on Thursday. There were 51 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Thursday?
Answers
Taking into account the definition of a system of linear equations, the local hamburger shop sold 199 hamburgers on Thursday.
System of linear equationsA system of linear equations is a set of equations in which every equation is linear., in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.
This caseIn this case, a system of linear equations must be proposed taking into account that:
"c" is the number of cheeseburgers sold on Thursday."h" is the number of hamburgers sold on Thursday.You know:
A local hamburger shop sold a combined total of 449 hamburgers and cheeseburgers on Thursday. There were 51 fewer cheeseburgers sold than hamburgers.The system of equations to be solved is
h + c= 449
h= c - 51
There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, substituting the second equation in the first you get:
c - 51 + c= 449
c+ c= 449 + 51
2c= 500
c= 500÷2
c= 250
Remembering that h= c - 51, you get:
h= 250 - 51
h= 199
