Answer:
y = -3/2x +11
Step-by-step explanation:
First you have to change the equation from standard form to slope form.
y = mx + b
2x-3y=7 --> subtract 2x from both sides
-3y = -2x + 7 --> now divide both sides by -3 to get y by itself
y = 2/3x - 7/3 --> the reason 2/3x is positive is because when there are two negatives it turns to a positive.
now you have to use point slope form y - y1 = m (x - x1)
x1 and y1 would be your point. 2 is x1 and 8 is y1
y - 8 = -3/2 (x - 2) --> the reason that m is -3/2 is because a perpendicular equation is the opposite reciprocal of the original slope
next distribute the -3/2
y-8 = -3/2x + 3 --> and now add 8 to 3 to get why by it self
now you have y = -3/2x + 11

how could you use a graph of a proportional relationship to find any ratio in the the proportional relationship why does this work?
It should be emphasized that a relationship is proportional if its graph is a line that passes through its origin.
How should the information be illustrated?
If the graph of a connection is a line passing through the origin, the connection is proportionate. If it is not a line or ray that fails to do this, the ratio is not proportional. The equation for the proportionality constant is K = y/x. This is the same equation used to get the slope of a straight line with respect to the origin.
If the graph of a relationship is a line or ray that goes through the origin, the relationship is proportional. If the line or ray does not pass through the origin, it is not proportional. Additionally, if anything is not linear, it is not proportionate.

To find the x-intercept, simply but y=0 in the equation given and solve for x
That is;
3x - 4y = 12
3x - 4(0) = 12
3x = 12
Divide both-side of the equation by 3
x= 4
The x-intercept is;
(4, 0)
To find the y-intercept, simply put y=0 in the equation given and then solve for y
That is;
3x - 4y = 12
3(0) - 4y = 12
-4y = 12
Divide both-side of the equation by -4
y = -3
The y-intercept is (0, -3)
Hence, the correct option is B.
x-int: (4,0)
y-int: (0, -3)

How many books must the publisher produce and sell so that the production costs will equal the money from sales?
4408 books must to be produced so that production costs is equal to sales money.
What is production cost?
Production costs refers to the direct and indirect costs that come from manufacturing a product. Production costs usually include expenses, such as labor, raw materials and manufacturing supplies. Cost of products sold are the production costs incurred on goods that is actually sold in a certain specified period
Let the no. of books= X
Cost = 9.25X + 49590
revenue = 20.50X
20.50X = 9.25X+ 49590
20.50X - 9.25X = 49590
11.25X = 49590
X = 4408
4408 books must to be produced so that production costs is equal to sales money
We can Check by:
cost = 9.25(4408) + 49590
= 40774+ 49590
cost = 90364

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms.
Third-degree, with zeros of -2,-1, and 5, and a y-intercept of -10.
Answer:
y = x³ -2x² -13x -10
Step-by-step explanation:
You want a polynomial with x-intercepts -2, -1, and 5, and a y-intercept of -10.
Polynomial factorsA polynomial with zero x = p will have a factor of (x -p). The three given zeros mean factors of the desired polynomial will be ...
p(x) = (x -(-2))(x -(-1))(x -5) = (x +2)(x +1)(x -5)
Expanding this gives ...
p(x) = (x +2)(x² -4x -5) = x³ -2x² -13x -10
This polynomial has a constant of -10, which will be its y-intercept. No additional scaling is needed.
The polynomial function is ...

a city planner wants to build a road perpendicular to D street. What is the slope of the new road?
The slope of the new road is zero.
How to find slope?The slope of a line is the change in y with respect to the change in x.
In other words, the slope of a line is rise over run.
Therefore, the new road the city planner wants to build is perpendicular to the the D street.
(5, 1)(5, 4)
slope of D street = 4 - 1 / 5 - 5
slope of D street = 3 / 0
slope of D street = infinity
An infinite slope is simply a vertical line. Therefore, it is only perpendicular to a horizontal line which will have a slope of 0. Hence, the new road should have a slope of 0.

The water pressure on a submerged object is given by P = 64d, then the
a. The answer to the subject of the formula, "d," is d = P/64.
b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet
A function can be defined as an expression, law or rule that shows the relationship between two variables.
These variables are namely;
Independent variableDependent variableGiven the role as;
P = 64d
Where;
P stands for pounds per square foot of pressure.
d represents the object's depth in feet.
Let's now make the variable "d" the focus of the formula.
The coefficient of the variable "d," which is 64, is used to divide both sides of the equation. So that the variable can stand on its own, this is done.
(a) We get,
P/64 = 64d/64
d = P/ 64
(b) P equals 672 pounds per square foot if there is pressure.
When the variable's value is substituted into the formula, we get;
d = P/64
Then,
d = 672/64
Discover the quotient,
d = 10. 5 ft.
The value is 10.5 feet .
Therefore,
a. The answer to the subject of the formula, "d," is d = P/64.
b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet.

The graph (g-f)(x)=-4x complies with the query.
Graph example: What is it?An edge denotes the connection between the x and y vertices and is represented by the pair (x ,y). In the examples that follow, circles stand in for vertices and lines for edges.
The graph indicates that line generated by function f(x) passes through the points (1,-3) and (0,0) and that line similarly passes through the points (1,1) and (0,0).
With the use of the formula Y-Y1 = y2-y1/x2-x1, we can thus determine the equation of the lines (x-x2)
Therefore, the equation of the line produced by the function f(x) y+3= 3-0/0-1 (x-1)
Function f(x) Equals 3x since y+3=-3x+3 y=-3x.
the line drawn by the function g(x) has the equation y=x, hence function g(x)=x.
