Answer:

The given relation is not a function.

Step-by-step explanation:

A relation is any set of ordered pairs, which can be thought of as (input, output).

A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).

Given the following relation: {(7, 4), (5, - 1), (3, - 8), (1, - 5), (3, 6)}

There is an input value (x = 3) that has two corresponding outputs (y-values): y = -8 and y = 6.  

Remember that a function can only take on one output for each input.

It also helps to do the Vertical Line Test, which allows us to know whether or not a graph is actually a function.  If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.  To use the vertical-line test, imagine dragging a ruler held vertically across the  graph from left to right. If the graph is that of a function, the edge of the ruler would hit the graph only once for every x -value.

Attached is a screenshot of the plotted points on a graph, where I performed the Vertical Line Test. The green line is the vertical line that contains two points that made the relation invalid as a function.

The given transformation of reflection, rotation and translation are rigid transformation

The transformation that must take any point A to any point B are;

Reason:

Question: The given quadrilaterals ABCD and A'B'C'D' are congruent

Required; To select all transformation that must take a point A to point B

Solution:  

A rotation of 180° about the midpoint of segment AB will change the places of points A and B

A(x, y) → R₁₈₀ → A'(-x, -y)

Let the coordinates of the origin be the midpoint of segment AB, and let (x, y) represent the coordinate of the point B(x, 0) we have;

∴ The coordinates of point A is A(-x, 0), which gives;

A(-x, 0) → R₁₈₀ → A'(x, 0) = point B

Therefore a rotation about the midpoint of AB must take point A to point B

The reflection of a point (x, y) about y-axis gives a point (-x, y), therefore, we have;

A(-x, 0) → Reflection across the y-axis → A'(x, 0) = point B

Therefore, a reflection across the perpendicular bisector of the line AB must take the point A to point B

A translation along the directed line segment AB of point A(-x, 0) 2·x units right gives;

A'(-x + 2·x, 0) = A'(x, 0) = Point B

Therefore, the transformations that must take any point A to any point B are;

Rotation of 180° around the midpoint of segment AB

Reflection across the perpendicular bisector

Translation by the directed line segment AB

Answer:

The value is 6

Step-by-step explanation:

Since the slope is 1/2, you can plot the coordinates 5,7.

5=x axis

7=y axis

After that you can use the formula rise/run = 1/2

Then you plot 3 on the graph. Then you use formula rise over run,

then you get 6

Explanation:

You are probably familiar with the formula [tex]a^2+b^2 = c^2[/tex] which is the pythagorean theorem.

The [tex]a^2[/tex] is the square of the first leg 'a', while [tex]b^2[/tex] is the square of the second leg b. Adding those two squares leads to the square of the hypotenuse c, aka [tex]c^2[/tex]. This only works with right triangles, which are triangles that have a 90 degree angle.

Answer:

(2 x 10 ^-3) x (4 x 10 ^4)=8 x 10 ^1

Step-by-step explanation:

The mass of a single seed can be written as 0.002 = [tex]2*10^{-3}[/tex]

There are total of 4.3602 * 10 ⁴seeds in the jar

Total mass is the multiplication of these both numbers.

Since we want an estimate, we can use 4 instead of 4.3602 in the 2nd number.

The rule to multiply two numbers in scientific notation is:

[tex](a*10^{b} )*(c*10^{d} )=(a*c)*10^{b+d}[/tex]

So using this formula we multiply the 2 numbers and get answer as follows:

[tex](a*10^{b} )*(c*10^{d} )=(a*c)*10^{b+d} \\(2*10^{-3} )*(4*10^{4} )=(2*4)*10^{-3+4} \\=8*10^{1}[/tex]

Answer:

x=20

Step-by-step explanation:

Given: x+3+x-8+x=55

Combine like terms: 3x-5=55

Add 5 to the other side: 3x=60

Divide both sides by 3: X=20

Answer:

The formula you will want to use is y(2) - y(1) over x(2) over x(1).

Basically, the Y variables (4 and 1) will be subtracted from each other. Aka, 1-4, which is -3. You put that over 5-(-5) or (5+5) which is 10. Now you have -3/10.
