We have,
To simplify the expression [tex]4(3x^2y^4)^3 / (2x^3y^5)^4,[/tex] we can simplify each part separately and then divide.
Let's simplify the numerator first:
[tex](3x^2y^4)^3 = 3^3 * (x^2)^3 * (y^4)^3 = 27x^6y^{12}[/tex]
Now, let's simplify the denominator:
[tex](2x^3y^5)^4 = 2^4 * (x^3)^4 * (y^5)^4 = 16x^{12}y^{20}[/tex]
Now we can divide the numerator by the denominator:
[tex](27x^6y^{12}) / (16x^{12}y^{20})[/tex]
To divide the variables with the same base, we subtract their exponents:
[tex]27/16 * x^{6-12} * y^{12-20}[/tex]
Simplifying further:
[tex]27/16 * x^{-6} * y^{-8}[/tex]
To make the exponents positive, we can move the variables with negative exponents to the denominator:
[tex]27/(16x^6y^8)[/tex]
Therefore,
The simplified expression is [tex]27/(16x^6y^8).[/tex]

193 miners need to ride the elevator to the bottom of the mine. The elevator can hold 7 miners at a time. How many miners will be in the elevator on its last trip?
Answer:
4
Step-by-step explanation:
193/7=27 with a remainder of four.
[tex]\huge \bf༆ Answer ༄[/tex]
Here's the solution ~
There are total of 193 mimers and each time the elevator can carry 7 miners, now divide the numbers and the remainder ww get gives the number of people left at last, that is also equal to the number of miners in the last trip since they are the last group among them.
[tex] \sf193 \div 7[/tex]On dividing, we get quotient = 27 and remainder as 4
therefore, 28th trip will be the last trip carrying 4 miners.
I hope that helps ~

Please plot this linear equation on a graph, and also explain how to plot it.
[tex]y=3x-7[/tex]
Answer:
See below:
Step-by-step explanation:
Hello! I hope you are having a nice day.
We can solve this equation in a single step, we just need a bit of theory and a graph.
We can first see that its in [tex]y=mx+b[/tex] form. Which is also known as Slope-Intercept form.
This means that we know the following.
[tex]b[/tex] is the y coordinate of the y intercept.[tex]m[/tex] is the slope of the line.Since we know that, we can see that from our equation that the slope of the line is 3 and the y intercept is (0,-7).
Now that we've gotten that, we can start graphing.
The y intercept is -7 so we can plot (0,-7) as one of our points.
The slope of 3 means that we got up 3 units then right a single unit.
Therefore, another point could be (1,-4).
With our two points, we can create our graph by creating a straight line through those two points and therefore plotting our line.
Cheers!
Answer:
Step-by-step explanation:
y = 3x - 7 is a linear equation with y-intercept -7 (or (0, -7) ) and slope 3. These two quantities are instantly readable from the equation.
There are several ways in which we may graph this equation. One is to plot the y-intercept (0, -7) Then choose an x-value, such as 3, and evaluate the function at that x value. We see that y = 9 - 7, or y = 2, when x = 3. Then another point on the graph besides (0, -7) is (3, 2). Plot (3, 2) and then draw a line through the two plotted points.
Here's another way:
The slope here is 3, or 3/1, which represents rise / run. Plot (0, -7) as before.
Move your pencil from (0, -7) 1 space to the right and 7 spaces up. Then plot a new point at that location. Draw a line through (0, -7) and (1, 0).

7x + 1039 = 245x
Please help!
Answer:
x = 4.37
Step-by-step explanation:
7x + 1039 = 245x=> 1039 = 238x=> x = 4.36554621849 (Using calculator)=> x = 4.37 (Estimated)Conclusion:
Therefore, x = 4.37.Hoped this helped
[tex]GeniusUser[/tex]
Answer:
[tex]\frac{1039}{238}[/tex]
Step-by-step explanation:
7x + 1039 = 245x
Minus the smallest x from the largest.
1039 = 245x - 7x
1039 = 238x
Divide 1039 by 238x to find the x
[tex]\frac{1039}{238}[/tex] = x
A proportional relationship between the number of pounds of potatoes x and the price in dollars y is graphed and the ordered pair 4, 3 is on the graphed line
Part a: what is the price of 1 pound of potatoes show your work
Part b: what does the ordered pair 8,6 on the graph represent? Explain in words.
Answer:
A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the graphed line. Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (8, 6) on the graph represent? Explain in words. (2 points)
The point (4,3) means that 4 lbs. of potatoes = $3. Therefore, we have:
4 lbs / $3 = 1lb / x cross-multiply
4x = 3 divide by 4
x = 3/4 dollars = $.75 per pound
The point (8,6) means that 8 lbs. of potatoes = $6.

which does not represent two equivalent expressions 51 MAFS.6.EE.1.1 Which does not represent two equivalent expressions?
A.) 33=3·3·3
B.) 43=4·3
C.) 64=6·6·6·6
D.) 52=5·5
Answer: B
Explanation: 4 times 3 is equivalent to 12 and the question was asking for exponents. A has 3 multiplied by itself 3 times so that is correct. C has 6 multiplying itself 4 times so that would be correct. D has 5 Multiplying itself 2 times so that would be correct. The only one that does not represent equivalency would be B.
What is the absolute value? What symbol represents absolute value?
Answer:
Absolute value is the distance the number away is from 0. In simpler terms, if you had a -8 the absolute value is 8. I attached a picture of the absolute value symbols. The absolute value of a normal positive 8 is still 8 though because it's the same distance on a number line.

Answer:
[tex]7\frac{1}{3}[/tex]
Step-by-step explanation:
So for this problem, we want to solve for x
75x + 50 = 600
First, we isolate x by subtracting 50 from both sides.
75x + 50 - 50 = 600 - 50
75x = 550
Then we divide both sides by 75 to find x
75*x/75=550/75

Y = 4x + 9
What is the slope and the y-intercept?
Answer:
y=4x+9 is in the form y=mx+b , so the slope ( m ) is 4 and the Y-intercept ( b ) is 9
Answer:
m = 4b = 9Step-by-step explanation:
We know that:
y = mx + by = 4x + 9If we compare these two equations, we can find the slope and the y-intercept.
=> (y = mx + b) = (y = 4x + 9)
We can clearly see that 'm = 4' and 'b = 9'.
Conclusion:
Therefore:
m = 4b = 9Hoped this helped.
