the expression 2x+50 represents the elevation above sea level, in meters, of a rock climber after x minutes of climbing.
Which is the rock climbers initial height above sea level?
Enter your answer in the box.
The rock climbers initial height above sea level is:
50 meters.
Step-by-step explanation:The expression which is used to represent the elevation above sea level, in meters, of a rock climber after x minutes of climbing is given by:
2x+50
Now, we are asked to find the rock climbers initial height above sea level i.e. we are asked to find the value of the expression when x=0.
Hence, when x=0 we have:
2x+50=2×0+50
= 50
Hence, the answer is: 50 meters.

The sum of 16 and a number x is equal to 20
Compare the graphs of the pair of functions. Describe how the graph of the second function relates to the graph of the first function. y=-2(x) and y=-2(x)-3
The graph of the function y = -2 - 3 is shifted down 3 units from the graph of the function y = -2x.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The equations of the functions are:
y -2x
y = -2x - 3
The graph of the function y = -2x will be a straight line that is passing through origin (0, 0).
Applying transformation to the graph of the function y = -2x
y = -2x - 3
As we can see in the graph:
The graph y=-2x - 3 is shifted down 3 units from y = -2x
Thus, the graph of the function y = -2 - 3 is shifted down 3 units from the graph of the function y = -2x.

is 5.75 greater than 5 8/12
Yes, 5.75 is greater than 5 8/12 because 5 8/12 is equal to 5.67 which is less than 5.75.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
We have been given two numbers as
5.75 and 5 8/12
To determine the value 5.75 is greater than or less than 5 8/12
We have to convert the fraction 5 8/12 into the decimal,
⇒ 5 8/12
⇒ (60 + 8)/12
⇒ (68)/12
Apply the division operation,
⇒ 5.67
Therefore, 5.75 is greater than 5 8/12 because 5 8/12 is equal to 5.67 which is less than 5.75.

Given that (-4,5) is on the graph of f(x), find the corresponding point for the function f(2x)
Answer:
the correct answer is (-2,5)
Step-by-step explanation:
you multiply 1/2 by -4 to get the x value
To find the corresponding point on the function f(2x) given a point on the original function f(x), simply multiply the x-coordinate by 2. In this case, the corresponding point is (-8,5).
Given: Point (-4,5) is on the graph of f(x).
To find: Corresponding point for the function f(2x).
Solution:
When x = -4, 2x = 2*(-4) = -8.So, the corresponding point for f(2x) would be (-8,5).How to you solve this problem
22>= 5(2y+3)-3y how do I solve this
Final answer:
To solve the inequality 22 >= 5(2y+3)-3y, we distribute the 5, combine like terms, then isolate and solve for y, showing that y must be less than or equal to 1.
Explanation:
To solve the inequality 22 >= 5(2y+3)-3y, follow these steps:
Distribute the 5 into the parentheses: 22 >= 10y + 15 - 3y.Combine like terms on the right side: 22 >= 7y + 15.Subtract 15 from both sides to isolate the term with y: 7 >= 7y.Divide both sides by 7 to solve for y: y <= 1The final answer is that y must be less than or equal to 1.

A rectangle is twice twice as long as it is wide and has the same perimeter as a square whose area is 9 square feet feet larger than that of the rectangle. what are the dimensions of both the rectangle and the square?
The dimension of rectangle : 6 and 12 units
square= 9 units
What is Perimeter ?Perimeter is the distance around the edge of a shape.
Given:
let the width of rectangle be x.
length= 2x
let the side of square is y units.
Perimeter of rectangle = Perimeter of square
and, Area of square= Area of rectangle + 9
First, Perimeter of square= 4* side
= 4y units
Perimeter of rectangle,
=2(l+b)
=2(2x+x)
=6x units
Since, Perimeter of rectangle = Perimeter of square
6x=4y
3x=2y
Now, Area of square= Area of rectangle +9
y²= x*2x+9
y²= 2x²+9
y²= 2(2y/3)²+9
y²= 8y²/9+9
1/9 y²= 9
y²=81
y=±9
So, x=2y/3= 2*9/3
x= 6
Hence, dimension of rectangle is 6 and 12.
dimension of square is 9 units.

Rivka and Sara are sisters and contestants on a survival reality tv show. They must each build a raft that will ultimately carry them off the island. Rivka can build her raft in 5 days. Sara can build her raft in 6 days. Though, as sisters, they sometimes fight, they decided to work together to build their rafts. How many days will it take Rivka and Sara to build their two rafts? (Round your answer to one decimal.)
Final answer:
Rivka and Sara can build their two rafts together in approximately 5.5 days, as they have a combined work rate of 11/30 rafts per day when they work together.
Explanation:
Rivka and Sara, working together to build their rafts, would combine their work rates to find out how many days it will take to build two rafts. Rivka can build a raft in 5 days, which means her work rate is 1 raft per 5 days or 1/5 raft per day. Sara can build a raft in 6 days, equating to a work rate of 1/6 raft per day.
When they work together, their combined work rate is 1/5 + 1/6 rafts per day. To combine these, we find a common denominator:
1/5 + 1/6 = (6 + 5) / 30 = 11/30 rafts per day
The question asks how long it takes to build two rafts. Therefore, we divide the total number of rafts by their combined work rate:
2 rafts / (11/30 rafts per day) = (2 * 30) / 11 days = 60/11 days ≈ 5.5 days
Hence, Rivka and Sara will take approximately 5.5 days, or 5.5 days rounded to one decimal, to build two rafts if they work together without stopping.

Which expression represents the distance the two points, X and Y, on the number line?
|-4-7| is the expression represents the distance the two points, X and Y, on the number line
What is Number system?A number system is defined as a system of writing to express numbers.
Number line is a picture of a graduated straight line that serves as visual representation of the real numbers.
The x point is at minus four and y is at point three.
The distance will be always positive
As we count the units from -4 to 3 we get seven humps.
So the distance will be 7 units.
This we can get by taking |-4-3| which is |-7|=7 units.
Hence, |-4-7| is the expression represents the distance the two points, X and Y, on the number line
