Answer: Shayla's method for determining whether a graph of a relation is a function is not completely accurate. While it is true that a function can only have one y-intercept, the converse is not necessarily true. A graph can have exactly one y-intercept and still not be a function.

For example, a vertical line has exactly one y-intercept, but it does not define a function because the same value of x can have multiple y-values.

It is also important to note that a graph can be a function even if it does not intersect the y-axis at all.

A more accurate way to determine whether a graph represents a function is to use the vertical line test. This test states that if a vertical line can be drawn through the graph such that it intersects the graph in more than one point, then the graph does not represent a function. If a vertical line can be drawn through the graph such that it intersects the graph in exactly one point, then the graph represents a function.

Step-by-step explanation:

The system of inequalties on the graph is:

x  + 4y ≤ 15

y ≥ 0

First, we can see a solid line at y = 0 and we have the region above that line shaded, so one of the inequalities is:

y ≥ 0.

The other inequality is a solid line with a negative slope and the shaded region is below the line.

The only option that has these characteristics is:

x  + 4y ≤ 15

4y ≤ - x + 15

y ≤ (-1/4)x + 15/4

Then the system of inequalities is:

x  + 4y ≤ 15

y ≥ 0

Answer:

The annual passenger revenue of the rail transport corporation was $930 million when:

R = 930

-20|t-15| + 1,010 = 930

-20|t-15| = 80

|t-15| = 4

So, we can see that t-15 = 4 and t-15 = -4 both lead to an annual revenue of $930 million dollars.

To find the values of t, we add 15 to both sides of the equation:

t-15 = 4 => t = 19

t-15 = -4 => t = 11

So, the years where the passenger revenue was $930 million are:

The domain and range of the function y = 1/2 - 1 lies on  (-∞, ∞)

The collection of all input values (sometimes referred to as independent variables) for which a function is defined and yields a valid output is known as the domain of the function. It is the collection of all possible values that can be entered into a function.

All real numbers, for instance, fall inside the domain of the function        f(x) = x², since any real number may be squared to yield an accurate result.

On the other hand, a function's range is the collection of all feasible output values (also known as the function's dependent variable) that it can generate. It is the collection of all outcomes that the function is capable of producing.

For instance, since squaring real numbers makes the range of the function f(x) = x² all non-negative values.

It's vital to remember that not all functions have the same range or are defined for all conceivable input values. For instance, because the square root function x is not defined for negative numbers, all real numbers that are not negative fall within its domain.

In conclusion, the collection of all input values for which a function is defined and yields a valid output is known as the domain of the function. The collection of all potential output values that a function may produce is known as its range.

Answer: We can set up a system of equations to solve this problem. Let x be the number of quarters and y be the number of nickels. We know that:

x + y = 20 (the total number of coins)

0.25x + 0.05y = 4.20 (the total value of the coins in dollars)

We can use the first equation to solve for one variable in terms of the other, and then substitute that into the second equation to get a single equation with one variable.

For example:

x = 20 - y

0.25(20-y) + 0.05y = 4.20

5-0.25y + 0.05y = 4.20

5= 4.20

y = 20 - 5

y = 15

x = 20 - 15

x = 5

So Jada has 5 quarters and 15 nickels in her pocket.

Answer:

Step-by-step explanation:

a. To minimize the average cost, we need to find the value of x that minimizes the cost function C(x) = x² - 40x + 500.

This is the same as finding the minimum value of the parabola represented by the function. The vertex of the parabola is the point at which the parabola reaches its minimum or maximum value. The vertex form of a parabola is given by C(x) = a(x - h)² + k, where (h, k) is the vertex.

By comparing the given function with the vertex form of a parabola, we can find the vertex:

C(x) = x² - 40x + 500

= a(x - h)² + k

= (x - h)² + k

The x-coordinate of the vertex h = 40/2 = 20

So the minimum average cost occurs when 20 televisions are made per week.

b. To find the minimum average cost, we need to substitute the value of x = 20 into the cost function:

C(x) = x² - 40x + 500

= 20² - 40*20 + 500

= 400 - 800 + 500

= 100

So the minimum average cost is $100 per television.

If the average cost is $200 per television, we can set C(x) = 200 and solve for x:

200 = x² - 40x + 500

0 = x² - 40x + 300

This is a quadratic equation that can be solved by factoring or by using the quadratic formula.

we can factor it as

0 = (x-50)(x-6)

x = 50 or x = 6

The number of televisions made per week if the average cost is $200 per television is 50 or 6. Since 50 is much higher than 20, the minimum average cost, it is not physically possible to make 50 televisions with the average cost of $200 per television. So the answer is 6 televisions per week.

Answer:

L = 1/2x

Step-by-step explanation:

The perimeter of a rectangle is the sum of all four sides. In this case, the perimeter is represented by the expression 3 1/2x + 18.

Since the perimeter of a rectangle is the sum of the lengths of all four sides, so, if we know the perimeter and one side's length, we can find the length of the other side.

We can use the expression 3 1/2x + 18 to find the length of the rectangle.

Let's assume that the length of the rectangle is represented by the variable L and the width is represented by the variable W.

So we know that the perimeter of the rectangle is represented by the expression 3 1/2x + 18 and the perimeter of a rectangle is 2(L + W)

So we can write the equation

2(L + W) = 3 1/2x + 18

Expanding the left side of the equation:

2L + 2W = 3 1/2x + 18

Now we know that one of the sides of the rectangle is 1/2x so

L = 1/2x

Therefore, the expression that represents the length of the rectangle is 1/2x

A percentage is a figure or ratio that can be stated as a fraction of 100.

If we need to determine the percentage of the given number, we divide the number by its whole number and multiply it by 100. As a result, the percentage is one part in one hundred. "Per 100" is short for "per percent." It is represented by the symbol "%".

Given cost of radio = $109.65

and $109.65 is 43% of his savings,

let saving be  x

according to conditions,

43% of x = 109.65

43x/100 = 109.65

Answer: The largest marginal relative frequency is 0.90 and it represents the probability of an individual having brown hair given that they have brown eyes.

Step-by-step explanation:

The reason why 0.90 represents the probability of an individual having brown hair given that they have brown eyes is because the study shows that 90% of the people who have brown eyes also have brown hair. This is a conditional probability, which means that it is the probability of one event happening given that another event has already happened. In this case, the event of having brown hair is conditional on the event of having brown eyes. The probability of 0.90 is calculated by taking the total number of individuals with brown eyes and brown hair and dividing it by the total number of individuals with brown eyes. The number is large because 90% of the individuals with brown eyes have brown hair, it is the largest because it is the highest probability among the other marginal relative frequencies. This indicates that the majority of people with brown eyes also have brown hair

The length of AC is 7 units.

To find the length of AB and BC, use the distance formula.

[tex]\begin{aligned}AB&=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\&=\sqrt{(2-(-2))^2+(5-1)^2}\\&=\sqrt{(4)^2+(4)^2}\\&=\sqrt{16+16}\\&=\sqrt{32}\\&=4\sqrt{2}\;\sf units\end{aligned}[/tex]
