Write the equation for the function graphed below.
A hot air balloon is at an elevation of 1,250 feet. Its elevation begins to change at a rate of -22.5 feet per minute. How many minutes will it take the balloon to descend to an elevation of 935 feet? Use the Distance Formula: d = rt
Let y represent the number of feet and x represent the number of minutes. Convert 22 1/2 to decimal form: 22.5
y = -22.5x
Plug in -315 for y
-315 = -22.5x
divide both sides by -22.5
14 = x
It will take 14 minutes.

Answer:
Month: no
(13,33)…. Yes
Time,distance: yes
(1,2)… no
Age, shoe size: no
(x,y) yes
Step-by-step explanation:
Step-by-step explanation:
A relation is any set of ordered pairs, which can be thought of as (input, output).
A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).
First row:
Months (input) and Days (output) = not a function. The month of February has two corresponding outputs: Days of 28 and 29.
{(13, 33), (17, 25), (22, 22), (25, 17), (33, 17)} = this relation is a function. Each input value (x-coordinate) corresponds to exactly one output value (y-coordinate).
Plot of Distance (mi) vs. Time (h): the graph represents a function. Each input value (x-coordinate) corresponds to exactly one output value (y-coordinate).
Second row:
{(1, 2), (5, 2), (5, 4), (7, 6), (11, 6), (11, 8)}: this relation is not a function. The input value of 5 has two corresponding output values: 2 and 4. The same goes with the input value of 11, which has two output values of 6 and 8.
Table of Age (x) and Shoe Size (y): does not represent a function. The x = 15 has two corresponding y-values: 10 and 10.5.
Diagram of x and y (bottom-left corner): this relation represents a function. Each input value corresponds to exactly one output value.

Find the equation of the line that contains the point p(3,5) and is parallel to the graph of 5x+y= -2
9514 1404 393
Answer:
5x +y = 20
Step-by-step explanation:
The equation of the parallel line will have the same x- and y-coefficients. The constant will be adjusted to make the equation true at the given point.
5x +y = 5(3) +(5) = 20
The parallel line is ...
5x +y = 20

Step-by-step explanation:
A natural gas company charges a fixed customer fee of $ 12.60 every
month even if no natural gas is used. For every unit of natural gas used,
the customer is charged an additional $0.64.
a. Using x as the number of units used in a month and y as the total
monthly cost, write an equation
y = 12.60 + 0.64x
Step-by-step explanation:
y = $12.60 + $0.64(x)
y = 12.60 + 0.64x

Answer:
A) 1
Step-by-step explanation:
Let the distance from A to BC be represented by y, and the distance DE be represented by x. We can write some relations using the definition of the tangent of an angle, and the double-angle formula for tangent. The double-angles are complementary
Left angles
Call the smaller angle α. Then the larger angle is 2α.
tan(α) = x/2
tan(2α) = 2tan(α)/(1 -tan(α)²) = 2(x/2)/(1 -(x/2)²) = 4x/(4 -x²)
Right angles
tan(β) = x/3
tan(2β) = 2tan(β)/(1 -tan(β)²) = 2(x/3)/(1 -(x/3)²) = 6x/(9 -x²)
__
Angles 2α and 2β are complementary, so the product of their tangents is 1.
(4x/(4 -x²))(6x/(9 -x²)) = 1
24x² = (4 -x²)(9 -x²) . . . . multiply by the product of denominators
x⁴ -37x² +36 = 0 . . . . . put in standard form
(x² -36)(x² -1) = 0 . . . . . factor
Solutions to this equation are x = ±1 and x = ±6. Only positive values less than 1.25 can possibly satisfy the geometry. Hence x = DE = 1.
The length of DE is 1.

Let A and B be two disjoint events such that P(A) = 0.47 and P(B) = 0.3.
What is P(A or B)?
Work Shown:
P(A or B) = P(A) + P(B)
P(A or B) = 0.47 + 0.30
P(A or B) = 0.77
Notes:
The formula only works if A and B are disjoint, aka mutually exclusiveIf A and B are not disjoint, then use this formula: P(A or B) = P(A) + P(B) - P(A and B)Answer:
P(A or B) = 0.77

4×4×4×4×4×4
6×6×6×6
Hello there!
Another way to write 4^6 is 4×4×4×4×4×4.
Because 4^6 means 4 times 4 times 4 times 4 times 4 times 4.

Answer:
see attached
Step-by-step explanation:
a) One way you can try to identify the pattern is to look for the differences between the images shown, then divide those differences by 2. For example, the total number of vertical dots is 2, then 4 in patterns 2 and 4. This suggests the total number of vertical dots is equal to the pattern number..
The total number of horizontal dots is 4, then 6 in patterns 2 and 4. This suggests that the number of horizontal dots increases by 1 in each pattern. This would mean pattern 1 would have 3 total horizontal dots and 1 total vertical dot. It will look like one row of 3 dots.
Pattern 3 will have 5 total horizontal dots and 3 total vertical dots. The sequence of patterns will look like the attachment.
__
b) The total number of dots in each pattern is 2×(pattern number) +1. Then the number of dots in Pattern 7 will be 2×7 +1 = 15 dots.

Step-by-step explanation:
If f(x) = 2x and g(x) = 5x + 2, what is (f + g)(x) when x = 3?
Answer:
f÷g=2x+5x+2=7x+2
x=3
7×3+2=21+2=23
The value of (f + g)(x) when x = 3, if f(x) = 2x and g(x) = 5x + 2, is 23.
What is function?The function is a relationship between a set of potential outputs and a set of possible inputs, where each input has a single relationship with each output. This means that if an object x is present in the set of inputs (also known as the domain), then a function f will map that object to exactly one object f(x) in the set of potential outputs (called the co-domain).
Given:
f(x) = 2x and g(x) = 5x + 2
Calculate (f + g)(x) as shown below,
f(x) + g(x) = 2x + 5x +2
f(x) + g(x) = 7x + 2
Put x = 3
f(3) + g(3) = 7 × 3 + 2
f(3) + g(3) = 23

For what values of x is f(x) = x a function?
Answer:
All real values of x.
Step-by-step explanation:
f(x) = x passes the line test, as it is a simple line with a slope of 1, so by that reasoning, f(x) = x is always a function.
