The lines are perpendicular to each other because 2 and - 1 are opposite reciprocals of each other.
O The lines are neither parallel nor perpendicular to each other because - and are not opposite reciprocals
of each other.
The lines are neither parallel nor perpendicular to each other because 2 and - 3 are not opposite reciprocals of
each other.
Answers
Answer:
The correct option is Option C
Step-by-step explanation:
We are given the lines: [tex]y=-\frac{4}{5}x+2 \ and \ \ y=-\frac{5}{4}x-\frac{1}{2}[/tex]
The lines are perpendicular if they have opposite slopes i,e [tex]m_1=-\frac{1}{m_2}[/tex]
In line 1 the slope is [tex]-\frac{4}{5}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-4/5)
In line 2 the slope is [tex]-\frac{5}{4}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-5/4)
The opposite reciprocal of -4/5 is 5/4
So, the lines are not perpendicular as their slopes are not opposite reciprocal of each other.
If the lines are parallel there slope must be same. Hence lines are not parallel as well.
So, The correct option is Option C

Angles are both equal to 100 degrees
Step-by-step explanation:
Assuming that 7x-40 = 2x +60
1. Order of Operations
2. 5x = 100
3. divide 100 by 5
4. x = 20
5. Plug 20 into both equations
6. 7(20) - 40 = 100

Answers
Answer:
y=-2
Step-by-step explanation:
First, find the slope using the slope formula: m=y2-y1/x2-x1
Plug the numbers into the equation and get 0
Using the slope and one of the coordinates, put the equation into point-slope form: y-y1=m(x-x2)
y+2=0(x+4)
Distribute and simplify to get the final answer.
y+2=0+0

Answer:
The rate is 15 minutes per meter.
Step-by-step explanation:
It takes 9 minutes to fill a depth of meters.
Filling meters take 9 minutes time.
Filling 3 meters of the aquarium takes = 45 minutes time (Multiplying by 5 both the numbers).
In order to fill 1 meter of the aquarium it will take minutes (Dividing by 3 both the numerical values).
===================================================
Work Shown:
8 minutes = (2/5) meters
5*(8 minutes) = 5*( (2/5) meters )
40 minutes = 2 meters
40/2 minutes = 2/2 meters
20 minutes = 1 meter
The unit rate in minutes per meter is 20 minutes per meter.
In other words, it takes 20 minutes to raise the level 1 meter.

Mr. Olivera wants to buy a bicycle that costs $184 for each of his two children. He plans to save the $9 he usually spends for lunch to buy the bikes. About how many days must he save his lunch money to have enough to buy the bicycles? Will the actual number of days be more or less than the estimate?
Answers
Answer:
19 days its 180 y 20 days its 189
(Hope this helped in some kind of way and can i get brainlest? okay bye have a blessed day!)
The actual number of days required to buy a bicycle will be 20 days.
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Mr. Olivera wishes to purchase a $184 bicycle for each of his two children. He intends to save the $9 he normally spends on lunch to purchase the bikes.
Let 'x' be the number of days. Then the inequality is given as,
9x ≤ 184
Simplify the equation, then we have
9x ≤ 184
x ≤ 184 / 9
x ≤ 20.44
The actual number of days required to buy a bicycle will be 20 days.

Answers
Answer:
The correct answer is Option 2:

Step-by-step explanation:
Associative property consists of three quantities. Associative property for addition states that the result of adding three numbers will be same no matter what the order of addition is.
Let a,b and c be three numbers
Then associative property can be stated as:
[tex]a+(b+c) = (a+b)+c[/tex]
Now looking at the options it can be observed that the following choice shows the associative property
[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]
Hence,

Derek analyzed the relationship between the mean number of points scored per game by a basketball team and the team's mean home attendance for several seasons. Derek uses the function y=−7,628+325.5x to describe the data. In the function, x represents the mean number of points scored per game, and y represents the mean home attendance. If the team's mean number of points scored per game is 60 next season, what does the model predict that the team's mean home attendance will be? The model predicts that the mean home attendance will be _____ .
Answers
Answer:
Step-by-step explanación
0.02
When the mean number of points scored per game next season is 60, the model predicts that the mean home attendance will be 11902
The function that predicts the attendance is given as:
[tex]y = -7628+325.5x[/tex]
When the mean number of points scored per game next season is 60, it means that the value of x is 60
i.e. x = 60
Substitute 60 for x in the function
So, we have:
[tex]y = -7628+325.5 \times 60[/tex]
Evaluate the product
[tex]y = -7628+19530[/tex]
Add -7628 and 19530
[tex]y = 11902[/tex]
Hence, the model predicts that the mean home attendance will be 11902
