Identify the inverse g(x) of the given relation f(x).
f(x) = {(8, 3), (4, 1), (0, –1), (–4, –3)}

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

so convert the equation -x + y = 5 into slope intercept form by adding x to both sides

(-x + x) + y = 5 + x

0 + y = 5 + x

y = 5 + x

To match the slope intercept formula switch the x and 5 around

y = x + 5

If lines are parallel then they have the same slope (m) but they have different b

This means that the slope of the line will be 1 (in front of the x is an invisible 1 which would be m)

This is what we have so far...

y =  x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(2, -5)

-5 = 1(2) + b

-5 = 2 + b

-7 = b

y = x + (-7)

y = x - 7

Hope this helped!

USE y=mx+b

Answer:

(-1, -9)

Step-by-step explanation:

Recall that for 2 points (x1, y1) and (x2,y2)

the midpoints are given by

x ordinate = [tex]\frac{x1+x2}{2}[/tex]

y ordinate = [tex]\frac{y1+y2}{2}[/tex]

In our case x1 = 8, y1 = -10, x2 = -10, y2=-8

x ordinate = [tex]\frac{x1+x2}{2}[/tex]  = [8 + (-10) ] / 2 = -1

y ordinate = [tex]\frac{y1+y2}{2}[/tex] = [-10 + (-8) ] / 2 = -9

hence midpoint is (-1, -9)

Answer:

The the midpoint of given line segment = (-1, -9)

Step-by-step explanation:

Points to remember

Midpoint formula

Midpoint of a line segment with end points (x₁, y₁) and (x₂, y₂) is given by,

Midpoint = [( x₁ + x₂)/2 , (y₁ + y₂)/2]

To find the midpoint of given line segment

Here (x₁, y₁) = (8, -10) and (x₂, y₂) = (-10, -8)

Midpoint = [( x₁ + x₂)/2 , (y₁ + y₂)/2]

 = [(8 + -10)/2 , (-10 + -8)/2]

 = [-2/2, -18/2]

 = (-1, -9)

Therefore the midpoint of given line segment = (-1, -9)

we know that

The ratio of fruits  and vegetables is equal to

[tex]\frac{x}{y} =\frac{5}{7}[/tex]

Part 1) Find the number of vegetables Monkey A

we know that

[tex]\frac{x}{y} =\frac{5}{7}[/tex]

[tex]x=30\ fruits[/tex]

substitute and solve for y

[tex]\frac{30}{y} =\frac{5}{7}[/tex]

[tex]y=30*7/5=42\ vegetables[/tex]

Part 2) Find the number of fruits Monkey B

Step-by-step explanation:

The length of line segment VT in which SU and VT are chords that intersect at point R is 13 units

An equation is an expression that shows the relationship between two or more numbers and variables.

Using the intersecting chord theorem:

VR * RT = SR * RU

(x + 1)(x + 4) = x(x + 6)

x² + 6x = x² + 5x + 4

x = 4

VT = VR + RT = x + 1 + (x + 4) = 4 + 1 + 4 + 4 = 13 units

Step-by-step explanation:

For a function to be a function, one of the easiest ways to tell is if an x-value has more than one y-value, because then it wouldn't pass the Vertical Line Test

But for choices A, C, and D, each x-value has 2 different y-values, failing the test

Out of the given options, the relation that describes a Functions is B) {(-2, −3), (-3, −2), (2, 3), (3, 2)}, as in this set, each x-value is only paired once with a unique y-value.

In the context of functions in Mathematics, a function is a relation where every domain (input) has exactly one unique range (output).

Looking at these four relations, the relation that describes a function would be B) {(-2, −3), (-3, −2), (2, 3), (3, 2)} because each x-value is paired with a unique y-value.

In other words, no x-value has more than one corresponding y-value.

For example, -2 is only paired with -3, -3 is only paired with -2, 2 is only paired with 3 - all unique pairs.

This is the definition of a function.

The other options (A, C, and D) all have x-values that are paired with more than one y-value, which violates the definition of a function.

In geometry, similar shapes have equal angles. If angle GHE (z) is 110 degrees, then angle CDA, in similar shapes, is also 110 degrees, simplifying angle-related problems.

In geometry, understanding the properties of similar and congruent shapes is essential. When two shapes are similar, it means that they have the same shape, and their angles are equal, but their sizes are proportionate. This concept provides a basis for solving problems involving angles in similar shapes.

In the given scenario, we are dealing with two shapes: GHE and CDA. When it's established that these shapes are similar, it means their corresponding angles are equal. Therefore, angle GHE (often denoted as 'z') is indeed equal to angle CDA.

Furthermore, the problem provides the measure of angle GHE (z) as 110 degrees. Using the information that angles in similar shapes are equal, we can confidently state that angle CDA is also 110 degrees.

In summary, the solution leverages the concept of similarity in geometry, where similar shapes have equal angles. Given that angle GHE (z) is provided as 110 degrees, it follows that angle CDA, being corresponding and equal in similar shapes, is also 110 degrees. This demonstrates how understanding similarity and congruence properties can simplify angle-related problems in geometry.

Answer:

1. F(x) = 5/4 x - 1

2. F(x) = 3x - 9

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

(1)

let (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (4, 4), then

m = [tex]\frac{4+1}{4-0}[/tex] = [tex]\frac{5}{4}[/tex]

Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1

y = [tex]\frac{5}{4}[/tex] x - 1 ← in slope- intercept form

(2)

let (x₁, y₁ ) = (4, 3) and (x₂, y₂ ) = (1, - 6), then

m = [tex]\frac{-6-3}{1-4}[/tex] = [tex]\frac{-9}{-3}[/tex] = 3, hence

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 3), then

3 = 12 + c ⇒ c = 3 - 12 = - 9

y = 3x - 9 ← in slope- intercept form

To find this, we just divide 450 “the amount of money Maria earns in 5 days” by 5 “number of days it takes for Maria to earn $450”

“450 ÷ 5 ≈ 90”

Maria earns around $90 in just 1 day.

Answer:

Option D. [tex]\frac{64}{25}[/tex]

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its surface areas is equal to the scale factor squared

In this problem

The scale factor is equal to [tex]\frac{8}{5}[/tex]

therefore

The ratio of its surface areas is equal to

[tex](\frac{8}{5})^{2}=\frac{64}{25}[/tex]

Final answer:

The ratio of the surface areas of the two similar rectangular prisms, given the ratio of their edge lengths is 8.5, is the square of that ratio, which is 72.25.

Explanation:

If the rectangular prisms are similar, their corresponding sides are proportional. Given that the ratio of their edge lengths is 8.5, we know that the corresponding sides of the two prisms are in the ratio of 8.5:1.

Since surface area is determined by the area of each face, and the area of each face is proportional to the square of the length of the corresponding edge, we square the ratio of their edge lengths to find the ratio of their surface areas.

Let's denote the ratio of surface areas as S. We have:

S = (8.5)² = 72.25

Therefore, the ratio for the surface areas of the rectangular prisms is 72.25:1. This means that the surface area of the larger prism is 72.25 times greater than the surface area of the smaller prism.

Answer:

Answer:

2.6  cm

Step-by-step explanation:

7 - 4.4 = 2.6 cm

-

The difference between 7 cm and 4.4 cm is 2.6 cm. But since we need to round to the place value of the less precise measurement (7 cm), our final answer is 3 cm.

To find the difference between 7 cm and 4.4 cm, we simply subtract the smaller number from the larger one. So, we have 7 cm - 4.4 cm which equals 2.6 cm. However, we need to round to the place value of the less precise measurement. The least precise measurement here is 7 cm (as it's rounded to the nearest whole number), so we round our answer to the nearest whole number as well, which gives us 3 cm.
