Answer:
1. y = 1/4x-1 or y = 0.25x-1

Step-by-step explanation: Hello! You can do this by using the slope-intercept equation.  The slope-intercept formula is y = mx+b.  You have the x and y coordinates already, which is all you need to solve the equation.  m = slope, b = y-coordinate in the formula y = mx+b.  The first thing you have to do is find the slope.  To find the slope, use the formula (y2 - y1)/(x2-x1).  The y-coordinates are the second numbers in the coordinate pairs, and the x-coordinates are the first numbers in the coordinate pairs.  Put the information in the formula.  You now have: (0 - (-2))/(4 - (-4)).  Two negatives make a positive, so you can simplify this equation by writing (0 + 2)/(4 + 4).  Add both equations.  You now have 2/8.  You can simplify this even more by dividing the numerator and denominator by 2.  2/8 divided by 2/2 = 1/4.  You now know the slope is 1/4.  

The next thing you have to do is use the point-slope formula.  The point-slope formula is y - y1 = m(x - x1).  m = slope, so put the slope you know (1/4) in the equation.  y - y1 = 1/4(x - x1).  You also know that y1 = -2 and x1 = -4 from the given coordinate pairs.  Fill this information in.  
y - (-2) = 1/4(x - (-4)).  Two negatives make a positive, so you can simplify this into: y + 2 = 1/4(x + 4).  Distribute 1/4 to x and -4.  1/4 x x = 1/4x, and 1/4 x 4 = 1.  You now have y + 2 = 1/4x + 1.  Subtract 2 from both sides.  y + 2 - 2 = 1/4x + 1 - 2. You now have y = 1/4x-1.  This is in the format y = mx+b, which is what you are supposed to do.  The answer for question 1. is y = 1/4x-1.  Hope this helps you with the rest of the problems! If you still need help after this, I can teach you how to do the second question as well.

The process of inverse the function is  f⁻¹(x) = x/2.

In math the term function is known as a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.

Here we have to explain the process of solve inverse functions with examples.

While we take the function for examples as

f(x) = 2x.

Now, we have to do the following steps to identify the inverse of the function,

Here the first steps is to replace f(x) by y in the equation describing the function, then we get

=>  y = 2x

Now, we have to interchange x and y in a simple terms now we have to replace replace every x by a y and vice versa, then we get,

=> x = 2y

Then the next step is to Solve for y, here we get

=> y = x/2

Finally replace y by f⁻¹(x)

Therefore, the inverse of the function is

=> f⁻¹(x) = x/2.

The interior angle measurement of a regular polygon with 42 sides is 150 degrees.

The interior angle measure of a regular polygon is determined by the formula (n-2)*180/n, where n is the number of sides of the polygon. In the case of a regular polygon with 42 sides, this formula can be expressed as (42-2)*180/42, which simplifies to 150 degrees. Therefore, the interior angle measure of a regular polygon with 42 sides is 150 degrees. This means that each interior angle of the polygon is 150 degrees. The exterior angle measure of a regular polygon with 42 sides would be 10 degrees, which can be calculated by subtracting the interior angle measure from 180 degrees. Knowing the angle measure of both the interior and exterior angles of a regular polygon with 42 sides is useful for a variety of applications, such as modeling or designing.

The mirror image of (3,2) in X-axis => (-3,-2), Y-axis => (3,-2).

The term mirror image of the point is a reflected duplication that appears identical but in reverse.

Here we have given points (3,2).

And we have to find the mirror image of this point with respect to the y-axis that is the mirror image is a point whose distance is the same from the origin O (0, 0) and the same from both axes as of the point (3,2).

As we all know that (3,2) lies on the first quadrant, then the mirror image with respect to the y-axis must lie on the second quadrant.

And we all also know that In the second quadrant, here the x-coordinate of any point (x, y) is negative.

Therefore, while we looking into the given graph we have identified that the mirror image is (-2, 3).

what is adjacent angle?

Adjacent angles are two angles that share a common vertex and have a common side (or arm) but no common interior points. They are side by side angles and are next to each other. They are not always congruent but they share a common side, usually represented by a line. They can be acute, obtuse or right angles. They can also be complementary angles, meaning they add up to 90 degrees. For example, in a rectangle, the angles across from each other are called adjacent angles, they are both right angles.

Greater than symbol:

In mathematics, the greater than sign is placed between two values ​​where the first number is greater than the second number. For example, 10 > 5. Here 10 is greater than 5. For inequalities, the greater-than sign always refers to the greater value, and the sign consists of two equal length dashes joined at an acute angle on the right.

As we know math problems don't always end evenly. We may need to include inequalities such as greater than and less than signs. Statements can be expressed as mathematical expressions.

Example: 'x' is the number of students in the class. If she has more than 45 students in her class, and she has 5 students join her class again, then she has more than 50 students in her class. This statement is expressed mathematically as x + 5 > 45. fish . Crocodiles always want to eat more fish, so they can eat more fish, regardless of how many mouths they have open.

A positive and negative angle that are coterminal to angle 2π / 7 are 16π / 7 and - 12π / 7, respectively.

Two consecutive angles are coterminal if and only if the difference between their measures equals 2π radians. Given an angle θ, then the family of coterminal angles can be derived from following equation:

θ' = θ + 2π · i, where i is an integer.

Where θ' is a coterminal angle, in radians.

First, determine a positive coterminal angle: (i = 1)

θ' = 2π / 7 + 2π

θ' = 16π / 7
