Step-by-step explanation:

For the y-intercept, you need to look where the graph intersects with the y-axis. In this case, the graph intersects at -1.

For the x-intercept, you need to look where the graph intersects with the x-axis. In this case, the graph intersects at -4.

The horizontal asymptote is a y value the graph approaches but does not pass or touch. In this case, the y value is -2.

The vertical asymptote is a x value the graph approaches but does not pass or touch. In this case, the x value is -5.

There are 10 and 26 candy bars of each size did he buy.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Diego brought 16 candy bars $25.

And, large candy bars cost $1.25 and regular candy bars cost $0.75.

Now, Let number of large candy bars = x

And, Number of regular candy bars = y

Here, Diego brought 16 candy bars.

Hence, We get;

⇒ x + y = 16  .. (i)

And, large candy bars cost $1.25 and regular candy bars cost $0.75.

Hence, We get;

⇒ 1.25x + 0.75y = 25  .. (ii)

Multiply by 1.25 in (i) and subtract from (ii),  we get;

⇒ 1.25y - 0.75y = 20 - 25

⇒ 0.5y = - 5

⇒ y = - 10

And, from (i);

⇒ x + y = 16

⇒ x - 10 = 16

⇒ x = 26

The unknown angle in the intersecting secant is as follows:

m∠GPE = 27 degrees

Secant is a line that intersects a curve at a minimum of two distinct points.

Using angle of intersecting secant theorem, the angle made by two secants (a line that cuts a circle at two points) that intersect outside the circle is half of the furthest arc minus the nearest arc.

Therefore, m∠GPE can be found as follows;

Hence,

m∠GPE = 1 / 2 (mGE - mHF)

mGE = 97 degrees

mHF = 43 degrees

Therefore,

m∠GPE = 1 / 2 (97 - 43)

m∠GPE = 1 / 2 (54)

m∠GPE =54 / 2

m∠GPE = 27 degrees

1) The object and the image are equidistant from the mirror

2) The object and the image following the reflection across a plane mirror are have the same side lengths and are therefore congruent

3) The image of the triangle is upright, and virtual and inverted from left to right

The laws of reflection are;

1) The angle made by the incident ray and the normal line (the angle of incidence) is equal to the angle made by reflected ray and the normal line

2) The incident ray, the reflected ray and the normal are coplanar

3) The incident ray is on the other side of the normal with regards to the refracted ray

1) The distance of the points on the object from the mirror are the same as the distance of the corresponding point from on the image from the mirror

2) A reflection of an object across a plane mirror is a rigid transformation such that the size of the object and the size of the image are the same.

Therefore, ΔABC ≅ ΔA'B'C'

3) The coordinates of the image formed following the  reflection of a point (x, y) across the y-axis is; (-x, y)

The y-coordinate remains the same, and the x-coordinates changes from positive to negative, and the location of the object on the left of the y-axis, produces an image on the right of the y-axis. Therefore

Therefore, the image is upright and inverted from right to left

Answer:

  y = 3x -1

Step-by-step explanation:

You want the equation of the line through the points (0, -1) and (1, 2), among others.

The y-value when x=0 is the y-intercept. The table shows you it is -1.

The slope is the difference in y-values when x-values increase by 1. For the first two points in the table, the y-value shows an increase of ...

  2 -(-1) = 3

This means the slope is 3.

The slope-intercept equation of a line is ...

  y = mx +b . . . . . . . where m is the slope, and b is the y-intercept

For your line, we have determined m=3, b=-1, so the equation is ...

  y = 3x -1

Answer: Here it is

1) The range is {y | y ≥ 11.5}. This is true.

2) The domain is all real numbers. This is true.

3) The y-intercept is 4.5. This is False. The y-intercept is 7.

4) There is no X-intercept. This is true.

5) The rate of change is $4.5 per mug. This is true.

C(m) = 4.50m + 7 is a linear function, and the slope of a linear function represents the rate of change (or the unit rate of change) which is 4.5 dollars per mug. The y-intercept represents the cost when no mugs are ordered which is 7 dollars. As the domain is all real numbers this means that Marta can order any number of mugs. And as the range is {y | y ≥ 11.5} this means that the minimum cost for any order will be 11.5 dollars.

And as there is no X-intercept, this means that the function never crosses the x-axis, this means that the function can never have a y value of zero, which confirms that it doesn't have an X-intercept.

The solution set for the given graph is a null set or empty set.

Sets, in mathematics, are an organized collection of objects and can be represented in set-builder form or roster form.

Given is a graph of parallel lines, as we know in the system of linear equations, equations having parallel lines yields no solutions, therefore, for this also, there is no solution,

Therefore, the set will be null set or empty set.

Write the given statement as a conditional statement:

Write the given statement as a converse of the conditional statement:

Both the conditional and converse statements must have the same truth value to produce a biconditional statement.  Therefore, as both are true, we can write the biconditional statements:

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.

a. The probability that both adults think most celebrities are good role models is 0.0359

b. The probability that neither of adults think that celebrities are good model is 0.6559.

P(adult think most celebrities are good role models) = 209 / 1100

Since the first selected adult is not replaced, there are 1099 total adults left.

P(second adult think most celebrities are good role models) = 208 / 1099

So, P(both adults think most celebrities are good role models) = 209 / 1100 * 208 / 1099

Answer: The total amount Jennifer will owe to the bank on January 31st is $3,458.75

Step-by-step explanation: In September, Jennifer Rick went to Park Bank to borrow $2,500 at 11.75% interest for 4 months. As this loan is a simple interest loan calculated monthly, we need to calculate the total amount she will owe to the bank on January 31st.

We use the formula for simple interest which is:

Interest = Principal x Interest rate x Time

Interest = $2,500 x 11.75/100 x 4/12 = $958.75 (rounding to the nearest cent)

Now we can add the interest to the principal amount to get the total amount that Jennifer will owe to the bank on January 31st.

Total amount = Principal + Interest

Total amount = $2,500 + $958.75 = $3,458.75 (rounding to the nearest cent)

So, the total amount Jennifer will owe to the bank on January 31st is $3,458.75

The exponential equation that models the function of Maureen's car is 26,525 (0.92)

a = 26,525 and b = 0.92

Exponential function is a type of function of the form: f(x) = a(b)^x. It is made up of  3 main parts

a = the starting value

b = the base function

x = the exponents

Considering the problem,

the starting = $26,525

the base = depreciation

the exponents = x

A year ago hence x = 1

$24,403 = $26,525(b)¹

b = 24,403 / 26,525

b = 0.92

hence we can say that a = 26,525 and b = 0.92
