Answer:
C.) -5
Step-by-step explanation:
The slope formula is rise/run, in other words, rise divided by run or the y variable divided by the corresponding x variable.
In this question, we are told that the y-value is "20 feet above" meaning this is the rise and the run is "4 feet from"
To find the slope all we have to do is divide 20 by 4 giving us 5. Since the ladder is going down we know that we have to place a negative sign before the slope giving us our final answer of -5
A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 200 nails and each large box has 400 nails. The contractor bought twice as many small boxes as large boxes, which altogether had 3200 nails. Graphically solve a system of equations in order to determine the number of small boxes purchased, x,x, and the number of large boxes purchased, yy.

The slope of the graphed line is m = -5
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 0 , 2 )
Let the second point be Q ( 2 , -8 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2 - ( -8 ) ) / ( 0 - 2 )
m = 10 / -2
m = -5
Hence , the slope is m = -5

What is the domain of the function?
X+6
f(x)=(x-7)(x+5)
A all real numbers except 7
Ball real numbers except 5 and -7
Call real numbers except -5 and 7
D all real numbers
The required domain of the function is all real numbers except -5 and 7. Option C is correct.
Given that,
f(x) = (x + 6) /[(x-7)(x+5)]
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
Given function,
f(x) = (x + 6) /[(x-7)(x+5)]
We can put any real number on the number line except 7 and -5, because at these value function gives the value as infinity.
Thus, the required domain of the function is all real numbers except -5 and 7. Option C is correct.

Slope intercept
Answer:
the slope is 2/7 and the intercept is 4
Step-by-step explanation:
In order to find slope, you use the equation delta y over delta x which is the equation, y2-y1/x2-x1.
In this case you plug in each point and get the equation, 2-4/-7-0 or 4-2/0+7.
Simplify to get 2/7.
To find the intercept, you must see what's the y value when x is 0. In this case it's already given to you, so y intercept is 4.

What is 4/9 x 5/7 x 1/2
Answer:
0.16
Step-by-step explanation:
4*5*1=20
9*7*2=126
20/126=10/63
Answer:
10/63
Step-by-step explanation:
First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.
The basking shark can grow to a length of 30 feet. This is 176.47% of the maximum length of the beluga whale. Find the maximum length of the beluga whale. If necessary, round your answer to the nearest tenth.
a) 52.9ft
b) 17ft
c) 5.9ft
d)1.7ft
Answer:
b
Step-by-step explanation:
The maximum length of the beluga whale is 17 feet.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The basking shark can grow to a length of 30 feet.
This is 176.47% of the maximum length of the beluga whale.
Assuming the maximum length of a beluga whale is x feet.
So, 176.47% of x is 30 feet.
∴ (176.47/100)×x = 30.
1.7647x = 30.
x = (30/1.7647).
x = 17 feet.

Solve 2x=54xˆ(2/3)
Please, I need the step by step working to find the value of x
Answer:
x = 19683 or x = 0
Step-by-step explanation:
Solve for x:
2 x = 54 x^(2/3)
Hint: | Isolate the radical to the left hand side by reversing the equality.
2 x = 54 x^(2/3) is equivalent to 54 x^(2/3) = 2 x:
54 x^(2/3) = 2 x
Hint: | Eliminate the power on the left hand side.
Raise both sides to the power of three:
157464 x^2 = 8 x^3
Hint: | Move everything to the left hand side.
Subtract 8 x^3 from both sides:
157464 x^2 - 8 x^3 = 0
Hint: | Factor the left hand side.
Factor x^2 and constant terms from the left hand side:
-8 x^2 (x - 19683) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by -8:
x^2 (x - 19683) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
x - 19683 = 0 or x^2 = 0
Hint: | Look at the first equation: Solve for x.
Add 19683 to both sides:
x = 19683 or x^2 = 0
Hint: | Look at the second equation: Eliminate the exponent.
Take the square root of both sides:
Answer: x = 19683 or x = 0
