Write the phrase "Four times the difference of six and y equals five less than y" as a variable expression:
Write the phrase "six more than nine times n is twenty" as an equation:
Answer: 4(6-y)
Step-by-step explanation: Since you are multiplying 4 by the difference of 6 and y, you put 6 and y in parenthesis with the 4 on the outside. Then 6-y goes inside the parenthesis.
Also the second one would be (6+9)n=20
Name one pair of parallel planes. All lines and planes that appear to be parallel are parallel.
The parallel plane is the plane that has the same in-between distance at all points on the plane so plane ABF is parallel with plane DCG so option (C) is correct.
What is the plane?The plane is a two dimension(2D) surface that has a surface area.
We can draw lines on a plane and two or more planes can intersect or parallel.
If two planes are parallel then the perpendicular distance between both planes must be the same.
The angle of inclination of two parallel planes with a single reference plane is also the same.
In the given cuboid the plane ABF is parallel with plane DCG.
So, ABF || DCG.
Hence "The parallel plane is the plane that has the same in-between distance at all points on the plane so plane ABF is parallel with plane DCG".

a river barge travels at an average of 8 mi/h in still water. the barge travels 60 miles up the mississippi river and 60 miles down the river in a total of 16.5 hours. what is the average speed of the current in this section of the mississippi river? round the tenths place.
the average speed of the current in this section of the mississippi river is 5.8
let C = the speed of the current
then B - C = effective speed up river
B+C =effective speed down river
time up + time down = 16.5 hrs
60/B-C+60/B+C= 16.5
taking lcm and solving we get
480+60C +480-60C= 16.5 (64 - C^2)

Rollaround skate rink charges $5 admission and $3 per hour for a skate rental. Spinaround skate rink charges $8 admission and $1.50 per hour for a skate rental. Write an equation to determine at what point the cost of both roller skating rinks is the same.
Answer:
2 hours
Step-by-step explanation:
Let x be the time, in hours, for which the cost of Rollaround and Spinaround are the same.
Rollaround Cost (Cr): Cr = $5 + $3x
Spinaround Cost (Cs): Cs = $8 + $1.50x
We want to find the value of x that makes Cr = Cs
Cr = Cs
$5 + $3x = $8 + $1.50x
$1.50x = $3
x = 2 hours
====
CHECK:
Cr = $5+$3(2) = $11
Cs = $8+$1.50(2) = $11
At 2 hours, both cost the same.
Is the following a function??
The collection of all points in the plane with the form (x, f(x)) that make up a function f's graph. Alternatively, we may say that the graph of f is the graph of the equation y.
Explain about the function?A function is a type of rule that produces one output for a single input. Source of the image: Alex Federspiel. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is the input value, we would state that y is a function of x.

You have 200 feet of fencing to enclose a rectangular plot that borders on a river (a long side borders the river). If you do not fence the side along the river, find the length and width of the plot that will maximize the area. What is the largest area that can be enclosed?
The maximum Area that can be enclosed will be 5000 square feet.
In the given question, it is stated that 200 feet of fencing will be done to enclose a rectangular plot with borders on a river. It has a long side on the border of a river which does not needs fencing. We need to find out the Length and Width of the plot that will maximize the area and also find out the Maximum area that can be enclosed.
It is given that the total length of the fence is 200 feet.
Let the length of the plot be l
let the width of the plot be w
=> Total Perimeter will be = l + 2w because the longer side or 1 side of length does not need fencing. Putting the perimeter as 200 we get
=> l + 2w = 200 => Equation (1)
Now, we know the Area of the plot will be l*w,
By equation (1) we get l = 200 - 2w, Putting the values in the Area:
=> Area = (200-2w) * w
=> A = 200w - 2w²
For maximum Area, the derivative of A with respect to w will be 0
=> [tex]\frac{dA}{dW} = 200 - 4w[/tex]
=> [tex]0 = 200 - 4w[/tex]
=> w = 50
Putting w = 50 in Equation (1) we get
=> l = 100
We got our Length l = 100 feet, and Width w = 50 feet. Now we will Calculate the maximum Area to enclose.
=> Area = l*w
=> A = 100*50
=> A = 5000
Hence, the Maximum area to enclose will be 5000 square feet.

Find the 7th term in the
sequence
-4, -8,-16, . . .
Answer: -512
Step-by-step explanation:
to answer this problem you need to understand the sequence and hen extrapolate the sequence out until you get to the seventh term (which would be your answer).
looking at -4, -8, -16
First we clearly see that each number is a negative and an even number. going beyond this we see -4 goes into -8 twice and -8 goes into -16 twice (in other words the next number in the sequence is always double the proceeding number). Also, each number is an even factor of four which can help us with double checking at the end!
-4 --> (-4) + (-4) = -8 -8 --> (-8) + (-8) = -16 -16 --> (-16) + (-16) = -32 -32 --> (-32) + (-32) = -64 -64 --> (-64) + (-64) = (-120) + (-8) = -128 -128 --> (-128) + (-128) = (-200) + (-40) + (-16) = -256 -256 --> (-256) + (-256) = (-400)+(-100)+(-12) = -512Can also be seen as:
4 times (-2) = -8 4 times (-4)= -16 4 times (-8) = -32 4 times (-16) = -64 4 times (-32) = -128 4 times (-64) = -256 4 times (-128) = -512Double check by going back and reviewing you math as well as making sure each answer is even and divisible should be divisible by four!

Is y=x(1-x)-(1-x^2) a linear, quadratic, or absolute value
The y=x(1-x)-(1-x²) is a linear value that is not absolute.
Simplifying,
y=x(1-x)-(1-x²)
y=x-x²-1+x²
y=x-1
Thus, it is a linear equation with a negative value therefore it is not an absolute value.
Ax+By=C is the general form of a two-variable linear equation. When the equation is written in this manner, it is quite simple to obtain both segments (x and y).
Any polynomial that can be rewritten in the canonical form is a quadratic equation. where x represents an unknown quantity and a, b, and c represent known quantities, with a = 0. This indicates that f(x) = 0 is the root of function f(x) = ax2 + bx + c, which is the answer to the quadratic equation ax2 + bx + c = 0.

What is meant by regular octagon?A regular octagon is a closed figure with equal-length sides and equal-sized interior angles. It possesses rotational symmetry of order 8 and eight lines of reflective symmetry. The Schläfli sign "8" represents a regular octagon. A regular octagon's internal angle at each vertex is 135°. ( radians).
We know that for a regular polygon with n sides the measure of each of the exterior angle = 360/n
Also, the measure of each of the interior angles of the regular polygon with n sides = (n - 2) × 180 / n
We have n = 8 (octagon)
Therefore, the measure of each of the exterior angles is: 360/8 = 45
Measure of each of the interior angles is given by:
(8-2) × 180/8 = 1080/8 = 135
Measure of interior angle = 135°
Measure of exterior angle = 45°
