A coordinate plane with straight line. The line starts at (negative 5, negative 2) and passes through points at (negative 1, 0) and (4, 5).
What is slope?The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,
The slope of line is the measure of steepness or the direction of line the coordinate plane.
m = Δy/Δx
where,m is the slope
tan θ = Δy/Δx
We also refer this tan θ to be the slope of the line.
Slope of a LineThe slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.
Given:
slope= 4/5
The graph which show the slope 4/5 is:
A coordinate plane with straight line. The line starts at (negative 5, negative 2) and passes through points at (negative 1, 0) and (4, 5).

A car rents for $180 per week plus $0.25 per mile. Find the cost of renting this car for a two week trip of 400 miles for a family of 4.
Answer: $460
Step-by-step explanation:
It cost $180/per week. The family will have the car for 2 weeks, so:
($180)(2)= 360
Additionally, it is $0.25 per mile. The family traveled 400 miles, so:
($0.25)(400)= 100
In total:
$360 + $100 = $460
If α and β are zeroes of 2x² - 5x+7, find
polynomial whose zeroes are 2α + 3β , 2β + 3α .
α & β are the zeroes of 2x² - 5x + 7.
Find:polynomial whose zeroes are 2α + 3β , 2β + 3α .
Solution:On comparing with the standard form of a quadratic equation,
Let,
a = 2
b = - 5
c = 7.
We know that,
Sum of the zeroes = - b/a
⟹ α + β = - ( - 5)/2
⟹ α + β = 5/2 -- equation (1)
Product of the zeroes = c/a
⟹ αβ = 7/2 -- equation (2)
Now,
General form of a Quadratic equation is x² - (sum of the zeroes)x + product of the zeroes = 0.
★ Sum of the zeroes = 2α + 3β + 2β + 3α
⟹ Sum of the zeroes = 5α + 5β
⟹ Sum of the zeroes = 5(α + β)
Putting the value from equation (1).
⟹ Sum of the zeroes = 5(5/2)
⟹ Sum of the zeroes = 25/2
Similarly,
★ Product of the zeroes = (2α + 3β)*(2β + 3α)
⟹ Product of the zeroes = 2α( 2β + 3α) + 3β( 2β + 3α )
⟹ Product of the zeroes = 4αβ + 6α² + 6β² + 9αβ
⟹ Product of the zeroes = 13αβ + 6(α² + β²)
a² + b² = (a + b)² - 2ab → α² + β² = (α + β)² - 2αβ
⟹ Product of the zeroes = 13αβ + 6[ (α + β)² - 2αβ ]
Putting the values from equations (1) & (2) we get,
⟹ Product of the zeroes = 13(7/2) + 6 [ (5/2)² - 2(7/2) ]
⟹ Product of the zeroes = 91/2 + 6 ( 25/4 - 14/2 )
Taking LCM we get,
⟹ Product of the zeroes = ( 2 * 91 + 6 * 25 + 2 * 14 ) /2
⟹ Product of the zeroes = (182 + 150 + 28 )/2
⟹ Product of the zeroes = 180
Hence,
New quadratic equation = x² - (25/2) * x + 180 = 0
⟹ New quadratic equation = (2x² - 25x + 360)/2 = 0
⟹ New quadratic equation = 2x² - 25x + 360 = 0
∴ The required quadratic equation is 2x² - 25x + 360 = 0.
I hope it will help you.

Rectangle A measures 12 cm by 3 cm. Rectangle B is a scaled copy of Rectangle A. Select all of the measurement pairs that could be the dimensions of Rectangle B.
Answer:
The question is lacking multiple-choice answers, below is the complete question:
Rectangle A measures 12 cm by 3 cm. Rectangle B is a scaled copy of Rectangle A. Select all of the measurement pairs that could be the dimensions of Rectangle B.
A. 6 cm by 1.5 cm
B.10 cm by 2 cm
C. 13 cm by 4 cm
D.18 cm by 4.5 cm
E.80 cm by 20 cm
Answer:
The correct answers are:
A. 6 cm by 1.5 cm
D. 18 cm by 4.5 cm
E. 80 cm by 20 cm
Step-by-step explanation:
A scaled copy of the original rectangle will have different dimensions, but with the same ratio of the dimensions to the original unscaled rectangle. Therefore, to determine the dimensions that are scaled copies of the original rectangle, we have to determine the ratio of the dimension of the original rectangle and also find the ratios of the other rectangles, the ratios that match are scaled copies. This is done as follows:
Rectangle A:
12cm by 3 cm = 12/3 = 4
other rectangles:
A. 6cm by 1.5cm = 6/1.5 = 4
B. 10cm by 2cm = 10/2 = 5
C. 13cm by 4cm = 13/4 = 3.25
D. 18cm by 4.5cm = 18/4.5 = 4
E. 80cm by 20 cm = 80/20 = 4
The rectangles that match the original rectangle are A, D, and E, hence they are scaled copies of the rectangle A

If the slope of a line is m = -7, find the slope of the lines that are parallel and perpendicular to the line.
Answer:
For the line parallel to the line it has a gradient of -7 and the one perpendicular to the line has a gradient of 1/7.
Answer:
Parallel: m = -7
Perpendicular: 1/7
Step-by-step explanation:
The question is asking us to find the slope of the lines that are parallel and perpendicular to the one whose slope is -7.
Main Idea: Parallel lines have equal slopes; perpendicular lines have slopes that are opposite reciprocals.
The slope of the line that's parallel to the one whose slope is -7 is also -7.
The one that's perpendicular to it is the opposite reciprocal of -7, which is 1/7.
Therefore, this is the answer.

A company that manufactures widgets has fixed costs of $8,906.00 each month and a cost of $2.64 for each widget it produces. Which of the following equations could be used to determine the total production costs for the company if it produced x widgets last month?
(Let x represent the number of widgets the factory produced last month and y represent the total production costs for the factory.)
A.
y = $890.60 + $2.64x
B.
y = $8,906.00 + $2.64x
C.
y = $8,906.00x - $2.64x
D.
y = $2.64 + $8,906.00x
Answer:
The equation could be used to determine the total production costs for the company if it produced x widgets last month is
y = $8,906.00 + $2.64x ⇒ B
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope ⇒ rate of changeb is the y-intercept ⇒ initial amount∵ A company has fixed costs of $8,906.00 each month
→ That means it is a fixed value every month
∴ b = 8,906.00
∵ The cost of each widget it produces is $2.64 for
→ That means the value is changing according to the number of widgets
∴ m = 2.64
∵ y represents the total costs of production last month
∵ x represents the number of widgets the factory produced last month
→ Substitute the values of m and b in the form of the equation above
∴ y = 2.64x + 8,906.00
The equation could be used to determine the total production costs for the company if it produced x widgets last month is
y = $8,906.00 + $2.64x

I thought it was HL, but I was wrong. So I’m really confused. Help?
Answer:
Its asa
Step-by-step explanation:
Answer:
The answer to your question is the ASA(Angle-Side-Angle) postulate
Step-by-step explanation:
The reason this is not HL(hypotenuse leg) is because only one side, and two angles are marked as congruent, you need a congruent(equal measure) leg, hypotenuse, and right angle. In other words, you need a right triangle with a congruent hypotenuse, and leg ; tick marks, to indicate the sides have equal length(these are the slashes that go through the line or outline). An outline of the angle or tick on the outline corresponds to congruent angles.
Because you have two angles and a side, in the order of an angle then a side and then an angle, it is ASA.
Use the vertical line test to determine if the graph is a function or not a function.
Answer:
Use the vertical line test to determine if the graph is a function or not a function.
On a coordinate plane, a graph decreases to a minimum point, and then increases.
✔ function
On a coordinate plane, a graph increases to a maximum, decreases to a minimum, increases to the maximum, and decreases again to the minimum.
✔ function
On a coordinate plane, a graph decreases to the right, then decreases to the left, then decreases to the right.
✔ not a function
Step-by-step explanation:
As per the concept of the vertical line test, the third graph is not a function.
But the First and Second graphs represent a function.
The vertical line test is a method used to determine if a graph represents a function. It involves visually inspecting the graph and checking if any vertical line intersects the graph at more than one point.
Let's apply the vertical line test to the given graphs:
First graph:
For the first graph, if we draw any vertical line, it will intersect the graph at most once. Hence, the graph passes the vertical line test, indicating that it represents a function.
Second graph:
For the first graph, if we draw any vertical line, it will intersect the graph at most once. Hence, the graph passes the vertical line test, indicating that it represents a function.
Third graph:
The vertical line test is given in the image below.
In conclusion:
The third graph is not a function.
