The total problems assigned over the weekend are 15.

In mathematics, a fraction is used to denote a portion or component of the total. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, while the denominator is the number at the bottom. The denominator specifies the total number of equal parts in the whole, whereas the numerator specifies the number of equal parts that were taken.

Let us suppose the total number of problems assigned = x.

Given that the problems solved on Saturday is 3/5 of her total questions. This is represented as:

(3/5) x

The remaining problems are:

1 - (3/5) x = (2/5) x

On, Sunday the problems solved are 1/3 of the remaining. This is represented as:

(1/3) (2/5) x

(2/15) x

The remaining problems are:

(1 - 1/3)(2/5 x) = (2/3) * (2/5) x = 4/15 x

Given that the final number of problems remaining are 4, that is:

(4/15) x = 4

x = 4 (15/4)

x = 15

Hence, the total problems assigned over the weekend are 15.

The inequality form of the statement is: |4x - 2| ≤ 2. And the lowest value of x that makes this inequality true is x = -1.

To solve for the lowest value of x that makes this inequality true, we need to consider two cases:

If 4x - 2 ≥ 0, then |4x - 2| = 4x - 2, so the equation becomes:

4x - 2 ≤ 2

Adding 2 to both sides, we get:

4x ≤ 4

Dividing both sides by 4, we get:

x ≤ 1

If 4x - 2 < 0, then |4x - 2| = -(4x - 2), so the equation becomes:

-(4x - 2) ≤ 2

Adding 2 to both sides, we get:

-4x + 4 ≤ 4

Dividing both sides by -4, we get:

x ≥ -1

So, the solution to the inequality is -1 ≤ x ≤ 1. This means that any value of x that lies between -1 and 1, inclusive, satisfies the inequality.

So, the lowest value of x that makes this inequality true is x = -1.

Factor the radicand: If the radicand is not already in the form of a perfect square, you can factor it into its prime factors and pull out any perfect squares from the radicand.

For example, √(36) can be simplified to √(49) = √4 * √9 = 23.

Simplify the exponent: If the radical has an exponent (such as cube root), divide the exponent by the index of the radical. Example ∛64 = ∛(4^3) = ∛4 * ∛4 * ∛4 = 4 *4 *4 =4

Combine like factors: If there are any factors in the radicand that match the exponent, you can combine them and simplify the radical further. For example, √(2235) = √(2^235) = 2√(35) = 2√15 = 2*3 = 6.

It is important to note that not all radicals can be simplified to a whole number or a fraction. In some cases, the radical will be in its simplest form when it is left as an irrational number.

(f○g)(x) = f(g(x))

it simply means that we put the expression of g(x) into ask places of x in f(x).

(f○g)(x) = g(x)² + 3

therefore,

g(x)² + 3 = 9x² - 12x + 7

g(x)² = 9x² - 12x + 4 = (a + b)² = a² + 2ab + b²

9x² = a² tells us that a = ±3x

4 = b² tells us that b = ±2

which signs of a and b do we need ?

-12x = 2ab gives us the answer

-6x = ab

that means the signs need to be opposite and we have 2 possible solutions

g(x) = 3x - 2

The minimum number of pears that each must pack is x = 12 pears.

We can start by using algebra to represent the problem.

Let x be the number of pears that Kendrick and Nick must pack.

We know that the total number of pear that Kendrick packs is 8 pear per crate * the number of crates he packs = 8x. Similarly, the total number of pears that Nick packs is 4 pears per crate * the number of crates he packs = 4x.

Therefore, the total number of pears that Kendrick and Nick must pack is 8x + 4x = 12x. We are given that they must pack the same total number of pears, so we can set this equal to x. Therefore, we have:

12x = x

So the minimum number of pears that each must pack is x = 12 pears. This means that Kendrick must pack 12 pears in 8 crates and Nick must pack 12 pears in 4 crates.

The types of solutions for an equation depend on the type of equation, but in general, the most common types of solutions are: single solution, no solution and infinite solutions.

In mathematics, particularly in algebra, a solution of an equation is a value or a set of values that, when substituted into the equation, makes it a true statement.

Single solution: An equation has a single solution when it has exactly one value that satisfies the equation. This solution is unique and it can be found by solving the equation for the variable.

No solution: An equation has no solution when it is impossible to find a value that satisfies the equation. This happens when the equation is contradictory or inconsistent. For example, the equation "2x = 5x + 1" has no solution because no value of x can make the equation true.

Infinite solutions: An equation has infinite solutions when any value of the variable satisfies the equation. This happens when the equation is an identity, meaning it is true for all values of the variable. For example, the equation "2x + 0 = 2x" has infinite solutions because any value of x will make the equation true.
