Write the equation of the line that has the slope of 7/3
and goes through the point (7,-9) in standard form.
****
The equation of the line that has the slope of 7/3 is: y = (7/3) x - 27/49
What is equation of the line?Finding the slope and y-intercept is necessary to express the equation of a graphed line in y-intercept (y=mx+c) form, which can then be used to get the equation of the line. The ratio of y to x is known as the slope. A slope triangle should be drawn connecting any two spots you find along the line.
Standard form, slope-intercept form, and point-slope form are the three main types of linear equations.
Given that,
slope (m) = 7/3
Putting (7,-9) into the equation: y =mx+c
or, -9 = (7/3) × (7) + c
or, -9 = 49 /3 + c
or, c = (-9) × (3/49)
or, c = -27/49
Thus, the equation becomes:
or, y = (7/3) x + -27/49
or, y = (7/3) x - 27/49

The approximate error of weight is
lbs.
Answer:
The approximate error of weight is 6.241 - 6 = 0.241 lbs
The approximate error of the given weight is 0.241 lbs
How to find the approximate error of weight?The approximate error of weight is the difference between the claimed weight and the actual weight, which is:
Approximate error = Actual weight - Claimed weight
As per the question, we have
Actual weight = 6.241 lbs
Claimed weight = 6 lbs
Substitute the values in the formula and we get:
Approximate error = 6.241 lbs - 6 lbs
Approximate error = 0.241 lbs
Therefore, the approximate error of weight is 0.241 lbs.

be the maximum tile area so that it can be used for both the grounds?
The maximum area of the tile to contain both grounds is 12x²y²
How to determine the maximum area of the tile?From the question, we have the following parameters that can be used in our computation:
Area of ground A = 12x^2y sq. units
Area of ground B = 6xy^2sq units
Rewrite these areas properly
So, we have the following representation
Area of ground A = 12x²y sq. units
Area of ground B = 6xy² sq units
Express the areas as the products of their prime factors
This gives
Area of ground A = 2 * 2 * 3 * x * x * y
Area of ground B = 2 * 3 * x * y * y
From the above products, we have
Least common multiple = 2 * 2 * 3 * x * x *y * y

What is a Scale Factor?A scale factor is a ratio of change from a drawing to real life. Typically, a scale factor is unit-less; a scale factor of 48 (or 1:48) is saying that for one unit on the page, it represents 48 of the same units in real life.
A scale factor is the ratio between corresponding measurements of an object and a representation of that object.
How to do scale drawing?Scale drawings show an image either reduced or enlarged in size. The change between the original and the scaled drawing is generally represented by two numbers separated by a colon, like 10:1 (read as “ten to one”).
The difference between the ratio numbers represents the factor by which the scaled image is enlarged or reduced. So for a 10:1 scale ratio, a 1 inch (2.5 cm) drawing will be 10 inches (25 cm) in real life.
Methods are as follows :
Adjusting Image Size by Hand- Measure the object you’ll be scaling.Choose a ratio for your scaled drawing.Convert the actual measurements with the ratio.Start drawing the perimeter with a straight segment when possible. - Refer to the original drawing frequently.Use a piece of string to check the scaled lengths of irregular images.Add details after finishing the perimeter.Changing Scale Digitally-

Reason:
The horizontal width spans from 8 to 20. This is a distance of 20-8 = 12 units.
The height is some unknown, which I'll call x. We multiply the width and height to get the area. This area must be 1 to represent 100%. You can think of it like a pie chart. This applies to any probability distribution.
area = base*height
1 = 12*x

Use the Well Ordering Principle to prove that there is no solution over the positive integers to the equation: 4a3 + 2b3-c3. 2Proofs by other methods such as induction or by appeal to known formulas for similar sums will not receive full credit.
By using the well ordering principle we can easily prove that the equation
4a³ + 2b³ = c³ does not have any solution for positive integers.
Let (a, b, c) be a positive integer solution with c the smallest possible.
Then c³ is even as the sum of a factor of 4 and factor of 2 is always even .
hence c itself is even.
Let us consider c = 2c₀ ;
4a³ + 2b³ = (2c₀)³
or, 4a³ + 2b³ = 8c₀³
then 2a³+b³ = 4c₀³
This time, we see that b must be even. using the same principle as above .
Put b = 2b₀ ;
2a³ + 8b₀³ = 4c₀³
then a³ + 4b₀³ = 2c₀³
thus a = 2a₀ must be even,
and 4a₀³+2b₀³=c₀³,
i.e. (a₀, b₀, c₀) is another solution. But c₀ = c/2<c.
And we have taken c to be the smallest of the solutions.
hence we get a contradiction.
Therefore our assumption is not valid.

The zeros of a parabola are -4 and 3, and it passes through the point (1, - 40).
What inequality represents all ordered pairs outside the parabola?
Drag a number or symbol into each box to correctly complete the inequality.
Answer:
Step-by-step explanation:
so a(x+4)(x-3)is total form after putting the point you will have 4(x+4)(x-3)=y
so answer is 4x^2+4x-48=y

Answer:
$22.50
Step-by-step explanation:
Solve for x. Triangle stuff
Answer:
x=9
Step-by-step explanation:
these 2 angles are supplementary angles meaning added together they will equal 180 degrees
so we can add them together and set it equal to 180
(8x-3)+(16x-33)=180
combine like terms
(8x+16x)+(-3-33)=180
24x-36=180
+36. +36
24x=216
/24. /24
x=9
hopes this helps
Any help would greatly be appreciated.
The point of intersection is (0, -4).
What is the point of intersection?
In a plane, intersecting lines are any two or more lines that cross one another. The point of intersection, which can be found on all intersecting lines, is where the intersecting lines share a common point.
Here, we have
Given: f(x) = -x -4, g(x) -5x -4
The lines intersect where f(x) = g(x)
f(x) = g(x)
- x - 4 = -5x - 4
-x +5x = -4 +4
4x = 0
x = 0
Now, we put the value of x in f(x) and we get
f(0) = - 0 - 4
f(0) = -4
Hence, the point of intersection is (0, -4).

A customer is buying bath towels and hand towels and can spend no more than $100. Each bath towel costs $8, and each hand towel costs $5. The inequality 8x+5y ≤100 represents all possible combinations of x, the number of bath towels, and y, the number of hand towels the customer can buy.
Which graph best represents the solution set for this inequality?
There is an attachment that includes the graph for the inequality 8x + 5y 100.
How do you calculate the scenario's graph?
The parameters are as follows, taken from the query:
The customer's purchase must not exceed $100.
Each bath towel costs $8.
Each hand towel costs $5.
Inequality among the available combinations is another factor that we have.
8x + 5y ≤ 100
like that
x is the quantity of bath towels, while y is the quantity of hand towels.
Plotting the inequality's graph is the following step.
A graphing tool can be used for this.
In order to attach the graph, we enter the inequality in the graphing tool.
Keep in mind that the inequality is provided as
8x + 5y ≤ 100
See the inequality graph in the attached. 8x + 5y ≤ 100

(a) You have a 10 inch by 15 inch piece of tin which you plan to form into a box (without a top) by cutting a square from each corner and folding up the sides. How much should you cut from each corner so the resulting box has the greatest volume? (b) If the piece of tin is A inches by B inches, how much should you cut from each corner so the resulting box has the greatest volume?
Resulting box has the greatest volume for the values (25 ± 5√7)/6 .
This is a problem that can be solved using derivatives , maxima & minima and common logic.
Hence , going by logic :
Creating a flap of 'a' inches in width, the base of the box will be
(10 - 2a) by (15 - 2a)
and the depth of the box will be the width of the fold-up flap: a.
Then the volume of the box is
v = [tex]a(10 -2a)(15 -2a) = 150a -50a^2 +4a^3[/tex]
Using the derivative of the volume will be zero at the maximum volume.
0 = [tex]dv/da = 150 -100a +12a^2[/tex]
This has roots at
a = (100 ±√(100² - 4(12)(150)))/(2·12)
a = (100 ± √2800)/24 = (25 ± 5√7)/6
Only the smaller of these solutions gives a maximum volume.
You should cut (5/6)(5-√7) ≈ 1.962 inches to obtain the greatest volume.
Similarly , replacing the values of 10 by A and 15 by B , a generalized solution can be formed .
