Answer:
The Answer is A. (x, y) → (x, -y)
Step-by-step explanation:
Reflections
R x-axis (x, y) → (x, -y)
R y-axis (x, y) → (-x, y)
R y=x (x, y) → (y, x)
R y = -x (x, y) → (-y, -x)
Suppose you are driving. You notice that after driving for 4 hours, you are 135 miles from Seattle. You continue driving, and calculate that after driving 8 hours you are 255 miles from Seattle. What is your rate? How far do you drive every 9 hours? How far from Seattle are you after driving for 17 hours?
Answer:
1,423
Step-by-step explanation:
Your average rate is 36.7 miles per hour over nine hours
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
In the first 4 hours, you've averaged 33.75 miles per hour, but this is apparently not sustainable, since at 9 hours you've only averaged 36.7 miles/hour.
You continue driving, and calculate that after driving 8 hours you are 255 miles from Seattle. you've averaged 31.8 miles per hour
So the answer is that your average rate is 36.7 miles per hour over nine hours, although you did manage a faster burst of 50 mph for four hours once.

Liang bought a basket of apples to make pies for her friends. The basket of apples weighed ppp pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies.
Write an equation to describe this situation.
What was the total weight of the basket of apples?
Answer:
Equation: p - 3 = 17
Weight of basket of apples = 20 pounds
Step-by-step explanation:
Given that:
Weight of basket of apples = p
Weight of apples eaten by Liang = 3 pounds
Weight of left apples = 17 pounds
According to given statement.
p - 3 = 17
Adding 3 on both sides
p - 3 + 3 = 17 + 3
p = 20 pounds
Hence,
Equation: p - 3 = 17
Weight of basket of apples = 20 pounds
Work out the percentage change to 2 decimal places when a price of £125.99 is increased to £150.
Answer:
Percent change is 19.06%
Step-by-step explanation:
It is given that:
Price before change = £125.99
Price after increase = £150
Change = 150 - 125.99 = £24.01
Percent of change = [tex]\frac{Change}{Price\ before\ change}*100[/tex]
Percent of change = [tex]\frac{24.01}{125.99} * 100[/tex]
Percent of change = 0.1906 * 100
Percent of change = 19.06%
Therefore,
Percent change is 19.06%

Kala purchased a prepaid phone card for $25. Long distance calls cost 8 cents a minute using this card. Kala used her card only once to make a long distance call. If the remaining credit on her card is $21.48, how many minutes did her call last?
Answer:
44 minutes
Step-by-step explanation:
25.00-21.48=3.52
this means she used $3.52

what is 125% of 12.8
The required value of the given percentage is 16. "125%" represents 125 parts out of 100, which is equivalent to 1.25 times the original value.
To find 125% of 12.8, we can multiply 12.8 by 1.25.
First, we convert the percentage to decimal form by dividing it by 100. So, 125% becomes 1.25.
Next, we multiply 12.8 by 1.25:
12.8 × 1.25 = 16.
Therefore, 125% of 12.8 is 16.
Multiplying 12.8 by 1.25 increases it by 25% or adds one-quarter of the original value. Thus, the result of 16 represents an increase of 25% from 12.8.
Thus, the required value of the given percentage is 16.

Given: A= (0, 0), (2, 1). (3, 1.5). (4, 2). .}ls A a function and why?
Answer:
Yes, it is a function
Step-by-step explanation:
the definition of a function is "a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output." Our input is represented by x, or the first number in the parentheses, and our output is y, or the second number in the parentheses. Because each x value had exactly one output, or y, it is a function
Calculate the slope of the line on the graph using the
formula:
72-V1
m
X2 - X
The slope of the line is
_____m/s.
Given:
The graph of a line which represents position (m) at time (s).
To find:
The slope of the line.
Solution:
Formula for slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the given graph it is clear that the line passes through two points (0,0) and (1,4).
Using the above formula, we get
[tex]m=\dfrac{4-0}{1-0}[/tex]
[tex]m=\dfrac{4}{1}[/tex]
[tex]m=4[/tex]
Therefore, the slope of the line is 4 m/s.

The diameter of a baseball is approximately 3 inches. What is its volume?
Round your answer to the nearest whole number.
A. 9 in^3
B. 13 in^3
C. 113 in^3
D. 14 in^3
Answer:qe
Step-by-step explanation:
The volume of the baseball is 14 in³.
The volume of a sphere can be calculated using the formula:
V = (4/3)πr³
where V is the volume and r is the radius of the sphere.
We have,
Diameter = 3 inch
radius = diameter / 2 = 3 / 2 = 1.5 inches
Substituting the radius into the volume formula:
V = (4/3) π (1.5)³
V ≈ (4/3) x 3.14 x (1.5)³
V ≈ 14.13 in³
Thus, the volume of the baseball is 14 in³.

Answer:
(8, - 5 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 4 → (1)
- x - 3y = 7 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the x- term.
- 3x - 9y = 21 → (3)
Add (1) and (3) term by term to eliminate x, that is
0 - 5y = 25
- 5y = 25 ( divide both sides by - 5 )
y = - 5
Substitute y = - 5 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(- 5) = 4
3x - 20 = 4 ( add 20 to both sides )
3x = 24 ( divide both sides by 3 )
x = 8
solution is (8, - 5 )
