John’s boat beings 30 miles from the dock and is 50 miles from the dock after 5 hours. The distance of Roberta’s boat from the dock is represented by the function y = 5x + 25, where x represents time and y represents the distance from the dock.
Which boat was farther from the dock at the beginning, and which traveled more quickly?
A. John’s boat was farther from the dock at the beginning, but Roberta’s boat traveled more quickly.
B. Roberta’s boat was farther from the dock at the beginning, and it traveled more quickly.
C. John’s boat was farther from the dock at the beginning, and it traveled more quickly.
D. Roberta’s boat was farther from the dock at the beginning, but John’s boat traveled more quickly.

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Two sailboats are traveling along the same path away from a dock, beginning from different locations at the same time.
y = 5x+25
at starting x=0
y = 25 miles away from the dock
x = 5
y = 5×5+25
y = 50 miles
= (50 - 25)/5
= 5
Thus, the correct statement is John’s boat was farther from the dock at the beginning, and it traveled more quickly option (C) is correct.

a regular square pyramid is 3m height and the perimeter of its base is 16m find the volume of the prism if its height is 10cm.
Answer:
240
Step-by-step explanation:
Answer:
16 m^3
Step-by-step explanation:
Question:
"a regular square pyramid is 3m height and the perimeter of its base is 16m find the volume of the pyramid"
volume of pyramid = (1/3) * (area of base) * height
The perimeter of the base is 16 m, and the base is a square.
perimeter of square = 4 * side
4 * side = 16 m
side = 4 m
area of square = (side)^2
area of base = (4 m)^2 = 16 m^2
volume of pyramid = (1/3) * (area of base) * height
volume = (1/3) * (16 m^2) * 3 m
volume = 16 m^2
the table above shows the number of miles four different cars traveled and the amount of gasoline each car consumed. which car has the best mileage?
PLEASE HELP
Answer:
A. Pontiac
Step-by-step explanation:
Camry's mileage = Miles travelled / gallons of fuel used
= 196 / 11
= 17.82
Pontiacs mileage = Miles travelled / gallons of fuel used
= 220 / 13
= 16.92
Bluck's mileage = Miles travelled / gallons of fuel used
= 356 / 15
= 22.25
Toyotas mileage = Miles travelled / gallons of fuel used
= 583 / 21
= 27.76
The car with the best mileage is Pontiac

How do you find the run between two points? Can the rise be negative? Explain
Answer:
Step-by-step explanation:
To find run between two points, you will use the x-values.
For example, (2,3) and (4,5).
Your equation for slope is m=[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
To find the run of these two numbers, you will subtract the second x value from the first x value.
Your answer would be 2 for the run.
It is possible for the rise to be negative if the y value of the point is greater in the first point than the second.
Example:
points (2,8) and (5,1)
1 - 8 would equal -7.

in (1,8) is y greater than x + 5
Answer:
True.
Step-by-step explanation:
Note the point values: (x , y) = (1 , 8) ∴ x = 1, y = 8
Plug in the corresponding numbers to the corresponding variables in the equation:
y > x + 5
(8) > (1) + 5
8 > 1 + 5
8 > 6
8 is greater than 6, ∴ y is greater than x + 5.

Answer:
yes it would
Step-by-step explanation:
x=1 + 5 is six
y=8
8 > 6
8 > 1

The resale value of a textbook decreases by 25% with each previous owner. A new textbook is sold for $85. Which function represents the resale value of the textbook after x owners?
f(x) = 85(1 – 0.25)x
f(x) = 85(1 + 0.25)x
f(x) = 85(0.25)x
f(x) = (85 – 0.25)x
9514 1404 393
Answer:
(a) f(x) = 85(1 – 0.25)^x
Step-by-step explanation:
The growth rate is -25%, so the growth factor is 1-25% = 1 - 0.25.
Each increase in the number of previous owners causes the value to be multiplied by this growth factor, so the overall multiplier is (1 -0.25)^x
The value is the initial value times this multiplier:
f(x) = 85(1 -0.25)^x . . . . matches the first choice
The function that represents the situation is f(x) = 85 (1 - 0.25)ˣ
What is exponential decay?An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.
The exponential decay function:
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Let's call the resale value of the textbook after x owners as f(x). We know that the resale value decreases by 25% with each previous owner. This means that after the first owner, the resale value will be 75% of the original value.
After the second owner, it will be 75% of 75% (or 56.25%) of the original value.
Similarly, after the third owner, it will be 75% of 75% of 75% (or 42.1875%) of the original value, and so on.
Using this information, we can write the function f(x) as:
f(x) = 85 (0.75)ˣ
f(x) = 85(1 - 0.25)ˣ
where 85 is the original value of the textbook (when x = 0), and (0.75)ˣ represents the percentage of the original value after x owners.
Therefore, the function that represents the resale value of the textbook after x owners is described as f(x) = 85 (0.75)ˣ.

Step-by-step explanation:
i dont feel like putting the steps but ik this is correct
The answer is -4a -8ab -7b after subtracting 8b - ab + 7a from 3a - 9ab + b.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have two expressions:
8b - ab + 7a and 3a - 9ab + b
After subtracting:
= (3a - 9ab + b) - (8b - ab + 7a)
= -4a -8ab -7b
Thus, the answer is -4a -8ab -7b after subtracting 8b - ab + 7a from 3a - 9ab + b.
