The statements which best describes the value of the expression 18x – 35, when x = 2 is that the result is a whole number that is neither prime nor composite and is denoted as option D.
What is a Prime number?This is referred to as the number which is divided by one and itself and there must be exactly two numbers involved.
18x – 35 = 18(2) – 35
= 36 - 35 = 1
In the case of 1, the numbers involved is just one which 1 which is why it isn't regarded as a prime number. A composite number can be formed with two small integers and the formation of 1 is 1 × 1 which is why 1 isn't.

How many integer solutions are there to the equation x³ + 2x² -41x-25-17 on the interval 0≤x≤10?
The solution in the given interval is x =6
What is inequalities?A "equal to" symbol on both sides of an equation is not necessarily necessary for it to be balanced. It may also refer to a connection when two things are "not equal to," i.e., where one is better or worse than the other. Any relationship between two numbers or other mathematical expressions that leads to an unfair comparison is referred to in mathematics as an inequality. Certain algebraic mathematical expressions are known as inequalities.
Equation is :
[tex]x^{3} +2x^{2} -41x -25 =17\\x^{3} +2x^{2} -41x -42\\Put x =-1\\-1^{3} -2(-1)^{2} -41(-1) -42=0\\So, (-1) is the solution of the given equation and (x+1) must divide the equation so,\\\frac{x^{3} +2x^{2} -41x -42}{(x+1)} =x^{2} +x-42\\So we can write \\(x+1)(x^{2} +x-42)=0\\(x+1)(x^{2} +7x-6x-42)=0\\(x+1)(x-6)(x+7)=0\\So the solution of the equation are\\x_{1} =-1\\x_{2} =+6\\x_{3} =-7\\[/tex]
We need to find the integer solution in the interval 0≤x≤10
So total no. of solution in the given interval is 1
The solution in the given interval is x =6

The value of x in the triangle extended through W to X is 39.5°.
What will be the value of x in the triangle?It should be noted that a triangle has a total angle of 180° and also has three sides. Based on the information given, the following can be deduced:
Angle 1 = 3x - 4.
Angle 2 = 6x + 6
Angle 3 = x + 20
Therefore, the value of x will be gotten by adding the values and equating to 180°. This will be:
3x - 4 + 6x + 6 + x + 20 = 180
4x + 22 = 180
Collect like terms
4x = 180 - 22
4x = 158°
Divide
x = 158/4
x = 39.5°

Step-by-step explanation:
Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y=8800(1.573)^x
y=8800(1.573)
x
The given exponential function represents the growth in function with a percentage increase as 57.3%.
Given we have the exponential function as :
y=8800(1.573)ˣ
it is in the form of: y=k.aˣ
therefore, if a>2 then the function represents growth.
and if a<1 then the function represents decay.
now, x=1.573
1.573 > 1
so, the function represents change in growth.
therefore, 1.573 - 1
= 0.573
= 57.3%
hence the change in growth of the function is increased by 57.3%.

y is inversely proportional to a³
When a = 2, y = 10
a is directly proportional to x
When x = 4, a = 20
Find a formula for y in terms of x.
Give your answer in its simplest form.
The formula for y in terms of x is y = [tex]\frac{16}{25} x^{3}[/tex]
What is proportionality?Any relationship that has a constant ratio is said to be proportionate. For instance, the ratio of proportionality is the average number of apples per tree, and the amount of apples in a crop is proportional to the number of trees in the orchard.
Given that,
Y is inversely proportional to a³ When a = 2, y = 10
A is directly proportional to x when x = 4, a = 20
If y is inversely proportional to a³
[tex]\frac{y}{x^{3} }[/tex]∝1
y = [tex]\frac{k}{a^{3} }[/tex], where k is the proportionality constant
Given, a=2, y=10, then 10 = [tex]\frac{k}{2^{3} }[/tex]
k = 10 × 2³
k = 80
Substituting k = 80 back into the formula;
y = [tex]\frac{80}{a^{3} }[/tex]............. 1
Similarly, if a is directly proportional to x, then a ∝ x i.e a = kx
If x=4, a=20 then;
20 = 4k
k = [tex]\frac{20}{4}[/tex]
k = 5
Substituting k = 5 back into the formula;
a = 5x ....... 2
Substitute equation 2 into 1;
y = [tex]\frac{80}{a^{3} }[/tex]
y = [tex]\frac{80}{5x^{3} }[/tex]
y = [tex]\frac{80}{125x^{3} }[/tex]
y = [tex]\frac{16}{25x^{3} }[/tex]
Therefore, the formula for y in terms of x is y = [tex]\frac{16}{25} x^{3}[/tex]

A clock face has a radius of 8 inches. What is the area of the clock face. Round your number to nearest hundredth.
Answer:
200.96 square inches
Step-by-step explanation:
it's asking for the area of a circle
we know that the radius is 8, so we can just plug it into the circle area formula which is
area = (pi) r^2
you plug in 8 for r (r stands for radius)
8^2 is 64
64 times pi is 200.96 (because pi=3.14)

Margaret invests $3,500 in a savings account that offers 5% simple interest per annum. So interest she will get after 8 years is
What is simple interest ?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.
Given that : Margaret invests $3,500 in a savings account that offers 5% simple interest per annum.
S.I = [tex]\frac{(P)(R)(T)}{100}[/tex]
P = $3,500
R=5%
T=8 years
S.I = [tex]\frac{(P)(R)(T)}{100}[/tex]

The total amount received at the end of 1 year will be 242000
The amount available in Austin's saving account: $100,000
Rate of interest = 142% per year
Simple interest: Simple interest is a quick and simple formula for figuring out how much interest will be charged on loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
The formula for simple interest is given:
Simple Interest = P*R*T/100
where P = principal amount invested
R = rate of interest per year
T = time in years for which the amount is invested
Substituting the values in the formula we get:
Simple interest = 100000*142*1/100
= 142000
Total amount after 1 year = Principal invested + Simple interest earned
= 100000 + 142000

the reason they are positive is that a negative times a negative equals a positive ex: -3 x -3 = 9
next, combine the coefficients

f(x)=x-7; vertical stretch of 3 g(x)
The function that represents the vertical stretch by a factor of 3 of f(x) is given as follows:
g(x) = 3x - 21.
How are vertical stretches and compression applied to the graph of a function f(x)?Vertical stretches or compression to the graph of a function f(x) are applied by the multiplication of a constant a to the function, as follows:
g(x) = a x f(x).
Then the value of the constant determines if it is an stretch or a compression.
If the absolute value of the constant a is greater than 1, it is a stretch. If the absolute value of the constant a is less than 1, it is a compression.For this problem, we want a vertical stretch with a factor of 3, then the constant is given as follows:
a = 3.
Then the definition of function g(x) is given by:
g(x) = 3f(x)
g(x) = 3(x - 7)
g(x) = 3x - 21.
