The expression that represents the statement "four less than the product of 2 and a number g" is 2 g - 4.
We are given a statement:
four less than the product of 2 and a number g
We need to form an expression to represent that statement.
An expression is a combination of variables and constants by using the various operations of mathematics like addition, subtraction, division and multiplication.
So, first we will find the product of 2 and a number g.
This is:
2 × g = 2 g
Now, we will subtract 4 from the expression:
2 g - 4
Therefore, the expression that represents the given statement "four less than the product of 2 and a number g" is 2 g - 4.

Ian's car can go 224 miles on 7 gallons of gas during a drive bob used 6 gallons of gas, how far did he drive?
Ian drove 192 miles with 6 gallons
How to calculate the number of miles ?The first step is to calculate the number of miles he drove with one gallon
224= 7
x=1
cross multiply
7x= 224
x= 224/7
x= 32
The number of miles he drove with 6 gallons can be calculated as follows
32= 1
y= 6
cross multiply
y= 32 × 6
= 192
Hence he drove 192 miles with 6 gallons

The correct answer for given question is 6.
If every element of a non-empty set X has only one image or range to a non-empty set Y, a relation 'f' is said to be a function.
Or
If 'f' is the function from X to Y and (x,y) f, then f(x) = y, where y is the image of x and x is the preimage of y under function f. It is written as;
f: X → Y.
In accordance with the conditions stated in the question:
f(x) = 3x^2 and g(x) = 4x^3 + 1
The composition of functions is defined as fog(x) = f(g(x)), where the input for the function f(x) is the actual expression of the function g(x) in terms of "x":
f(g(x)) = f(4x^3 + 1)
f(g(x)) = 3(4x^3 + 1)^2
f(g(x)) = 3(4x^3 + 1) (4x^3 + 1)
f(g(x)) = 3(16x^6 + 8x^3 + 1)
f(g(x)) = 48x^6 + 24x^3 + 3
Therefore, the degree of the given expression is 6 (the highest power of the variable ‘x’)

C) 6 squareroot of 3.
D)12 squareroot of 3.
Answer: [tex]6\sqrt{3}[/tex]
Reason:
For any 30-60-90 triangle, the long leg is exactly [tex]\sqrt{3}[/tex] times as long compared to the short leg.
In other words,
[tex]\text{long leg} = (\text{short leg})*\sqrt{3}[/tex]
In this case, the short leg is 6 units long. The short leg is always opposite the smallest angle 30 degrees. Once again, this only applies to 30-60-90 triangles.
The circle below is centered at (4,-1) and has a radius of 3. What is it’s equation?
The equation of the area of the circle (x - 4)^2 + (y + 1)^2 = 9, that is, option B.
The standard form of an equation of a circle is (x - h)^2 + (y - k)^2 = r^2
where, r = radius of the circle and (h, k) are the coordinates of the center of the circle.
Here, we are given that a circle is centered at (4,-1) and has a radius of 3.
Thus, r = 3
h = 4
and k = -1
Therefore, the equation of the circles will be-
(x - 4)^2 + (y - (-1))^2 = 3^2
(x - 4)^2 + (y + 1)^2 = 9
Thus, option B, (x - 4)^2 + (y + 1)^2 = 9 is the correct option.

Step-by-step explanation:
Both are quadratic equations: -x^2 or x^2
Blue graph: x^2 since it's facing up
f(x)=(x-b)^2
Vertex: When x=-1, y=0 ==> 0=(-1+b)^2
0=-1+b
b=1
f(x)=(x+1)^2
f(x)=(x+1)(x+1)
f(x)=x^2+x+x+1
f(x)=x^2+2x+1

ann is 4 years older than Julie. 4 years ago, ann was twice as old as julie. find their present ages
The present ages of Ann and Julie are 12 years and 8 years, respectively.
What are the current ages of Ann and Julie?
Let x, y be the current ages of Ann and Julie, whose features are synthetized in the following linear equations:
Ann is 4 years older than Julie
x = y + 4
x - y = 4 (1)
4 years ago, Ann was twice as old as Julie
x - 4 = 2 · (y - 4)
x - 4 = 2 · y - 8
x - 2 · y = - 4 (2)
Now we proceed to determine the ages of Ann and Julie by solving the system of linear equations: (x, y) = (12, 8)
The present ages of Ann and Julie are 12 years and 8 years, respectively.

Trina wants to find the least expensive way to buy 24 necklaces. She wants to buy only one type of package. She has $48. The table shows the number of necklaces in a package and the cost of each package.
Trina should buy the $6 packages to get 24 necklaces for the least price as calculated by using multiplication and division.
A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics .One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division. The other operations are multiplication, addition, and subtraction.At a fundamental level, counting the instances in which one number is included within another is one interpretation of the division of two natural numbers.From the attached table let us calculate the cost of buying necklaces in the various packages by using multiplication and division.
For the $4 package:
Number of necklaces in the package = 3
Number of packages Trina should buy (division used) = 24 ÷ 3 = 8
Cost of 8 packages =$ 4 × 8 = $ 32
For the $5 package:
Number of necklaces in the package = 4
Number of packages Trina should buy(division used) = 24 ÷ 4 = 6
Cost of 8 packages =$ 5 × 6 = $ 30
For the $6 package:
Number of necklaces in the package = 6
Number of packages Trina should buy(division used) = 24 ÷ 6 = 4
Cost of 8 packages =$ 6 × 4 = $ 24
Therefore buying the $24 package is the cheapest.

The given statement: " all polynomials are rational functions but not all rational functions are polynomials." is true; its counterexample will be: Not all polynomials are rational functions but all rational functions are polynomials.
What is a polynomial?Polynomial refers to an algebraic equation that has more than two terms, particularly the accumulation of numerous phrases that each include a different power of the same variable (s).
Now,
A polynomial of degree n has at most n real zeros. The degree of a polynomial function determines the end behavior of its graph. A rational function is a function of the form: [tex]f(x)=\frac{P(x)}{Q(x)}, Q(x) \neq 0[/tex] and P(x) and Q(x) are both polynomials.A function that cannot be written in the form of a polynomial is not a rational function.Further,
A counterexample refers to an idea or a statement that contradicts an idea or a theory.Basically, we can infer that it is the negation of a statement.For the given statement, the negation would be given as: Not all polynomials are rational functions but all rational functions are polynomials.Hence, The given statement: " all polynomials are rational functions but not all rational functions are polynomials." is true; its counterexample will be: Not all polynomials are rational functions but all rational functions are polynomials.

How to determine the parallel lines?The given equations are linear equations
Linear equations are represented as
y = mx + c
Where the slope of the linear equation is
Slope = m
Linear equations that have the same slope are parallel
This means that y = mx + c and y = mx + b are parallel lines because the slopes of the linear equations is m
