What is the equation of the line that is perpendicular to y equals negative four x plus five and passes through the point four comma negative three ?

Answer

B

explanation

get the difference between the y valuesand divide it by the difference between the x values

[tex] \frac{9 - 6}{3 - 5} [/tex]

[tex] \frac{3}{ - 2} [/tex]

The slope of the line passing through the points (5, 6) and (3, 9) is -3/2.

Option B is the correct answer.

We have,

To determine the slope between two points, we can use the formula:

m = (y2 - y1) / (x2 - x1)

Given the points (5, 6) and (3, 9), we can substitute the coordinates into the formula:

m = (9 - 6) / (3 - 5)

m = 3 / (-2)

m = -3/2

Therefore,

The slope of the line passing through the points (5, 6) and (3, 9) is -3/2.

Answer:

3 1/8 packages of beads

Step-by-step explanation:

We know that Darnell uses 1 1/4 packages of beads to make 10 bracelets. In order to find how many packages of beads he'll need for 25 bracelets, we set up a proportion:

[tex]\frac{1\frac{1}{4} }{10} =\frac{x}{25}[/tex], where x is the number of packages needed

Cross-multiply:

25 * 1 1/4 = 10x

1 1/4 is just 1.25 in decimal form, so:

25 * 1.25 = 10x

31.25 = 10x

x = 3.125 = 3 1/8

So, Darnell will use 3 1/8 packages of beads.

~ an aesthetics lover

Answer:

We can calculate how many packages he needs to make 5 bracelets and then times that by 5 to see how many he'll need for 25

Step-by-step explanation:

First of all, let's turn 1 1/4 to [tex]\frac{5}{4}[/tex]

Now, if we divide the amount he needs for 10 bracelets by 2, we will have the amount he needs for 5 bracelets:

[tex]\frac{\frac{5}{4}}{2} = \frac{5}{4} * \frac{1}{2} = \frac{5}{8}[/tex]

Now, as 25 divided by 5 is 5, we can multiply our answer by 5 to get the amount needed for 25 bracelets:

[tex]\frac{5}{8} * 5 = \frac{25}{8}[/tex]

Now, we can turn this back into a mixed fraction:

[tex]\frac{25}{8} = 3\frac{1}{8}[/tex]

So the answer is 3 1/8 packages of bread.

Answer:

All functions are relations, but not all relations are functions. A function is a relation that for each input, there is only one output. Here are mappings of functions. The domain is the input or the x-value, and the range is the output, or the y-value.

Answer:

Step-by-step explanation:

A relation between members of two sets X and Y is any set of ordered pairs {(x1,y1) (x2,y2) … }, finite or infinite in their number, provided the first member is from X and the second member is from Y. (Let’s not mention the uncountable possibility here).

E.g., if X = {Sunday, Monday, …, Saturday} and Y = {1,2, …, 31}, then the set {(Monday,1) (Tuesday,2) … (Monday,8) (Tuesday,9) … (Sunday,28)} is a useful relation for some February calendar, somewhere. It is “one-to-many”. And note that set Y need not be covered, but X must be. This distinguishes the domain of the relation (days of the week here) from its codomain (whole numbers 1 to 31 here).

Considering the vast set of all relations, there is one subset of great importance, those relations that have unique codomain values for each domain value. That is, each x in X is paired unambiguously with exactly one y in Y. These special relations are functions. The set of y in Y which have been paired with some x in X is called the range of f. Functions may still be “many-to-one”, as in y = r(x) which gives x rounded to the nearest integer. Thus r(2.3) = r(1.9) = 2.

Within the subset of functions are the one-to-one functions, which also have the property that every y in the range is paired with exactly one x in the domain. Because of this, these are the only functions that have an inverse function. Thus, the inverse function can be written as {(y1,x1) (y2,x2) … }. This shows that the domain and range of the original function are exactly exchanged in the inverse function.

E.g., y = tan(x) is one-to-one with domain [-pi/4 , pi/4] and range [-1,1]. Its inverse is x = arctan(y) with domain [-1,1] and range [-pi/4 , pi/4]. The roles of x and y are unambiguous, and shouldn’t be exchanged: x always in [-pi/4 , pi/4] and y always in [-1,1].

-30, -9.3, |-18|, 35.

Answer: -30, -9.3, |-18| (which is now just 18), and 35

Step-by-step explanation: The absolute value sign around |-18| makes the -18 an 18. For example, |-5| will become positive 5. |7| would stay positive even with the absolute value sign.

As negative numbers get bigger, they go left on the number line, making them smaller. Positive numbers go right on the number line, making then bigger.

Answer:

2.4 cm

Step-by-step explanation:

The scaled dimension on the drawing [tex]=[/tex] (Scale-factor) [tex]\times[/tex] (Original dimension)

She decides to draw 1cm for the original length of 0.5m=50 cm.

For this, the scaled dimension on the drawing=1cm and

the original dimention=50 cm

So, the scale-factor = 1/50.

As the kitchen door is 1.2m wide, i.e the original width of the door is 120 cm.

So, the scaled width of the door is

[tex]120\times \frac{1}{50}=2.4 cm.[/tex]

Hence, on the drawing, the width of the kitchen door should be 2.4 cm.

The rates are equal

Step-by-step explanation:

To see if the rates are equal, divide both of the units by the number of minutes:

60/3

80/4

= 20

This means both rates are equal, since we got 20 for both of them

This means the rate is 20 units per 1 minute, for both rates.

So, the rates are equal.

The equation that describes the graph is the one in option a:

f(x) = 2*|x - 3| + 1

We can see that the graph is an absolute value equation with a vertex in the point (3, 1), so the absolute value function must be of the form:

f(x) = a*|x - 3| + 1

Now, we also can see that the arms open upwards, so the slope must be positive, and we can see that for each increment in x, we have an increment of 2 units in y, so the slope is a = 2.

This means that the function is:

f(x) = 2*|x - 3| + 1

So the correct option is a.
