Answer:
y= 1/4x - 4
Step-by-step explanation:
use point slope form which is:
y - y1 = m(x - x1)
we know that the slope will be 1/4 because perpendicular is a negative reciprocal.
plug everything into point slope form:
y + 3 = 1/4 ( x - 4)
we distribute the 1/4 and then subtract the three and we get our answer
y= 1/4x - 4

Simplify (1-3i)-(2-i)
Step-by-step explanation:
(1-3i)-(2-i)=
1-2-3i+i=
-1-2i
1-2-3i+i
= -1-2i
Step-by-step explanation:
I simplified it in a simple way by arranging like terms together and did the calculation. Here the like term of 1 is -2 and for -3i it's i. so 1-2= -1 and -3i+i= -2i according to integers rule.

the Determine slope of ( 5 , 6 ) and ( 3 , 9 )
A. m = 3/2
B. m = -3/2
C. m= 6
D. m= 1/6
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.

Darnell uses 1 1/4 packages of bread to make 10 bracelets. He make 25 bracelets how packages of breads will he use
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.

all functions are relations but why not all relations are functions
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].

The equation that describes the graph is the one in option a:
f(x) = 2*|x - 3| + 1
Which equation represents the graph?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.

Emily wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with a length of 6m and a width of 2m. She decides on a scale of 1cm to 0.5m. If the kitchen door is 1.2m wide, how wide should the door be on the scale drawing? Be sure to include units
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.

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.

Determine whether the following rates are equal or not using unit rates: 60 units in 3 minutes and 80 units in 4 minutes
Answer:
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
= 20
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.
