Answer:
A) y=1/5x
Step-by-step explanation:
Coz, the way you identify a perpendicular line is by looking for its negative reciprocal. The neagtive reciprocal of 5= 1/5
Now, to check the ans we can multiply the negative reciprocal by "m"
(m in y=mx+c or y=mx+b)
in this case the "m" is stated as 5, so all we need to do is 1/5*5 if the ans is 1 then your ans is right....and over here it is
So thats how you identify & check perpendicular lines!

blake is saving up on a new pair of headphones. He has $20 saved already, and he earns $10 for every lawn he mows. How many lawns will he have to mow to have at least $90 saved . What is the inequality and the solution?
Answer: 20× + 10 < 90
Step-by-step explanation:
Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7
What is inequality?Inequality is a mathematical statement that compares two values, expressing that one value is less than, greater than, less than or equal to, greater than or equal to, or not equal to another value.
Inequalities are commonly represented using symbols such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).
Let's assume Blake has to mow x lawns to have at least $90 saved.
Since he earns $10 for every lawn he mows, the amount he will earn by mowing x lawns is 10x.
Adding his initial savings of $20 to the amount he will earn from mowing lawns gives us the following inequality:
20 + 10x ≥ 90
Subtracting 20 from both sides:
10x ≥ 70
Dividing both sides by 10:
x ≥ 7
Therefore, Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7

The points (-2, 4) and (1,r) lie on a line with slope 3. Find the missing coordinate r.
Answer:
-9
Step-by-step explanation:
Slope = (y2 - y1)/(x2 - x1)
(r - 11)/(4 - (-1)) = (r - 11)/5
So, (r - 11)/5 = -4
r - 11 = -20
r = -9

Michelle wants to start saving for a new car. She has $500 already saved and she plans to save an additional $50 per month.
What kind of pattern do we see in this scenario? She plans to save $50 each month. For each month that goes by.
Michelle will increase her total savings by $ ____
Answer:
I believe the pattern is linear and for each month that goes by she earns $50
For each month that goes by, Michelle will increase her total savings by $50
How to describe the pattern?The given parameters are:
Initial balance = $500
Savings = $50 monthly
This means that at the end of every month, her savings increases by $50.
This kind of pattern is a linear pattern

Question: Reflective symmetry over y = (3/5)x ?
Answer: No
-------
Question: Reflective symmetry over y = (5/3)x ?
Answer: No
================================================
Explanation:
For any parallelogram that's a square, we'll have four lines of symmetry: The two diagonals and two extra lines of symmetry for the opposite pairs of sides.
In this case, we don't have a square (we can prove this by finding the lengths of each side of the parallelogram), so we move on.
--------------
If the parallelogram is a rectangle, then we'll have two lines of symmetry: one for each pair of opposite sides.
However, we don't have a rectangle either. We can prove this by finding the slopes of the blue lines of the parallelogram, and finding they are not perpendicular slopes.
So we move on.
---------------
The last case is a parallelogram that isn't a rectangle. So it's not a square either. That's what we have here. For parallelograms of this nature, there are no lines of symmetry. We cannot fold it along any line to have it match up with itself.
So that's why the answer is "no" to both of these questions.

No and No.

The image below shows two dilated figures with lines AB and A'B' drawn. If the larger figure was dilated using a scale factor of 3, what relationship do lines AB and A'B' have? (10 points)
Answer:
They have the same side lengths/angles except one is smaller than the other
Step-by-step explanation:
the smaller one is a "mini" of the larger one. a exact copy
The dilation is solved and the scale factor of line is A'B' = 3AB
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.
Given data ,
Let the scale factor of the dilation be represented as k
Now , the scale factor k = 3
So , the ratio of the corresponding sides is given by
A'B' / AB = 3
Multiply by AB on both sides , we get
A'B' = 3AB
Hence , the dilation is simplified as A'B' = 3AB

Video Games With an initial cost of $ 5000, a company will produce x units of a video game at $ 25 per unit. Write an equation that relates the total cost of producing x units to the number of units produced. Plot the cost of producing 100, 150, 200, 250, and 300 units.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Fixed costs= $5,000
Unitary variable cost= $25
First, we need to structure the total cost formula:
Total cost= fixed costs + unitary cost*number of units
Total cost= 5,000 + 25*x
x= number of units
For 100:
Total cost= 5,000 + 25*100= $7,500
For 150:
Total cost= 5,000 + 25*150= $8,750
For 200:
Total cost= 5,000 + 25*200= $10,00
For 250:
Total cost= 5,000 + 25*250= $11,250
For 300:
Total cost= 5,000 + 25*300= $12,500
