Answer:
y = 4x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (1, 3) ← 2 ordered pairs from the table
m = [tex]\frac{3+9}{1+2}[/tex] = [tex]\frac{12}{3}[/tex] = 4 , then
y = 4x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (1, 3 ) , then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 4x - 1 ← equation of line
Tank 1: 36 inches long, 18 inches wide, and 12 inches tall. How many gallons of water is in the tank?
I need a step-by-step explanation please
In a tank that is 36 inches long, 18 inches wide, and 12 inches tall have approximately 33 gallons of water.
How to calculate volume of a tank?The rectangular tank's volume may be calculated using the formula V = l*b* h, where "l" stands for the tank's length, "b" for its width, "h" for its height, and "V" for its volume.
Define volume.The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Volume = length*width*height
V=36*18*12
V=7776 inches^3
which is approximately 33 gallons.

Answer: m=3
Step-by-step explanation:
The strategy to finding the slope is the use the slope formula, which Is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Since we are given a point, we can directly plug them in and solve.
[tex]m=\frac{15-0}{5-0} =\frac{15}{5}=3[/tex]
The way we can use mental math is mainly because we are given the origin. We know that anything subtracted by 0 is itself. With the formula, the subtraction gives us 15 and 5. With basic division, we know that 15/5=3.

Andrew is kayaking in a river with a 6 mph current. Suppose that he can kayak 4 miles upstream in the same amount of time as it takes him to kayak 9 miles downstream. Find the speed (mph) of Andrew’s kayak in still water
If Andrew takes same amount of time to kayak 4 miles upstream and 9 miles downstream in a river with a 6 mph current, then the speed of Andrew’s kayak in still water is 15.6 miles per hour.
Therefore the answer is 15.6 mph.
We can begin solving the problem by using the equation:
Speed (relative to water) = Speed (in still water) + Speed (of the water)
Let x be the speed of Andrew's kayak in still water.
When kayaking upstream, his speed relative to the water is x - 6 mph (since the current is moving in the opposite direction at 6 mph).
When kayaking downstream, his speed relative to the water is x + 6 mph (since the current is moving in the same direction at 6 mph).
Since the problem states that it takes Andrew the same amount of time to kayak 4 miles upstream as it takes him to kayak 9 miles downstream, we can set up the following equation knowing time = distance/ speed :
4/ (x - 6) = 9/ (x + 6)
Simplifying and solving for x we get
4(x + 6) = 9(x - 6)
4x + 24 = 9x - 54
9x - 4x = 54 + 24
5x = 78
x = 15.6
So, Andrew's kayak speed in still water is 15.6 miles per hour.

What are the different types of time complexity analysis available?
There are five different types of Time complexity analysis:
Constant Time ComplexityLogarithmic Time Complexity Linear Time Complexity O(n log n) Time ComplexityQuadratic Time ComplexityWhat is Time complexity?
The computational complexity that describes the amount of computer time required to run an algorithm is known as time complexity in computer science. The time complexity of an algorithm is commonly estimated by counting the number of elementary operations performed by the algorithm, assuming that each elementary operation takes a fixed amount of time to perform.
As a result, the time required and the number of elementary operations performed by the algorithm are assumed to be proportional. Because the running time of an algorithm varies among different inputs of the same size, the worst-case time complexity, which is the maximum amount of time required for inputs of a given size, is commonly considered.

what is the value of x in the nearest whole number
Answer:
16
Step-by-step explanation:
To calculate x we must use the trig function of tangent:
as tangent is opposite divides by adjacent we can get this equation:
[tex]\tan 30 = \frac{9}{x}[/tex] which is equal to:
[tex]x=\frac{9}{\tan 30}[/tex] So x must equal to 15.588.. (just put the second bit in the calculator
As all the values provided are integers you round this to the nearest whole number:
16 (as the third digit, 5, rounds up)

Estimate 38 x 9= ___
Answer:
400
Step-by-step explanation:
The most accurate estimate among the given options is d) 400.
Given that we need to estimate the product of 38 x 9,
To find the product of 38 and 9, you can simply multiply the two numbers together:
38 x 9 = 342
Therefore, the actual product of 38 and 9 is 342.
Now, let's estimate the product using the given options:
a) 30: This is too low of an estimate. 38 is larger than 30, so the product should be greater than 30.
b) 50: This is also too low of an estimate. 38 multiplied by 9 is significantly larger than 50.
c) 120: This estimate is closer to the actual product, but still not accurate. 120 is smaller than the actual product of 342.
d) 400: This is a close estimate. 38 multiplied by 9 is close to 400.
In summary, the most accurate estimate among the given options is d) 400.

Answer: Kayden needs 12 more meters of railing.
Step-by-step explanation:
To find the perimeter of the roof garden I added up all the numbers you listed (12m+3m+7m+10m+20m+10m) to get a total perimeter of 62 meters.
Since Kayden already has 50 meters of railing we can subtract that from the total he needs to get the remaining amount needed.
62m - 50m = 12 meters of railing remaining.
