Answer: True
Step-by-step explanation: This is because the slope can be defined as the [tex]\frac{changein yvalues}{changeinxvalues}[/tex]. It is the ratio of vertical (y) and horizontal changes (x) between two points. Rate of change of a function compares these two changes. Speed is essentially the rate at which the position of an object changes, so they are essentially all the same.
Factor completely 9xy 36x − 10y − 40. Prime (y − 4)(9x − 10) (y 4)(9x − 10) (y 4)(9x 10).
The complete factor of the polynomial 9xy + 36x − 10y − 40 is (9x − 10) (y+4). Then the correct option is C.
What is polynomial?Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Factor completely 9xy + 36x − 10y − 40.
Take 9x common from the first two terms and -10 from the last two terms. we have
9xy + 36x − 10y − 40
9x (y + 4) − 10 (y + 4)
Take y+4 common, then we have
(9x − 10) (y + 4)
The complete factor of the polynomial 9xy + 36x − 10y − 40 is (9x − 10) (y+4). Then the correct option is C.

Find the perimeter of a rectangle in simplest expression form that has an area of
12x² - 11x - 5. Please make sure you show all your work for full credit.
=======================================================
Explanation:
I'll use the quadratic formula to find the roots or x intercepts. This slight detour allows us to factor without having to use guess-and-check methods.
The equation is of the form ax^2+bx+c = 0
a = 12b = -11c = -5This leads to...
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-11)\pm\sqrt{(-11)^2-4(12)(-5)}}{2(12)}\\\\x = \frac{11\pm\sqrt{361}}{24}\\\\x = \frac{11\pm19}{24}\\\\x = \frac{11+19}{24} \ \text{ or } \ x = \frac{11-19}{24}\\\\x = \frac{30}{24} \ \text{ or } \ x = \frac{-8}{24}\\\\x = \frac{5}{4} \ \text{ or } \ x = -\frac{1}{3}[/tex]
Now use those roots to form these steps
[tex]x = \frac{5}{4} \ \text{ or } \ x = -\frac{1}{3}\\\\4x = 5 \ \text{ or } \ 3x = -1\\\\4x - 5 =0 \ \text{ or } \ 3x+1 = 0\\\\(4x-5)(3x+1) = 0[/tex]
Refer to the zero product property for more info.
Therefore, the original expression factors fully to (4x-5)(3x+1)
Use the FOIL rule to expand it out and you should get 12x^2-11x-5 again.
----------------------------------------------
We did that factoring so we could find the side lengths of the rectangle.
I'm using the fact that area = length*width
L = length = 4x-5W = width = 3x+1The order of length and width doesn't matter.
From here, we can then compute the perimeter of the rectangle
P = 2(L+W)
P = 2(4x-5+3x+1)
P = 2(7x-4)
P = 14x - 8

Vance wants to construct a circle tangent to all three sides of the acute, scalene triangle LMN using the following steps.
He will draw altitudes from vertex L and vertex M, and mark their intersection point as O.
He will draw the perpendicular from point O to side MN, and mark the intersection point as P.
He will draw the circle centered at point O which will pass through point P.
Which part of Vance's plan requires revision?
A.
Vance should have found the intersection of two perpendicular bisectors of triangle LMN instead of two altitudes.
B.
Vance should have found the intersection of two angle bisectors of triangle LMN instead of two altitudes.
C.
Vance should have used the compass to draw a circle through point N instead of point P.
D.
Vance should have constructed all three altitudes instead of only constructing two altitudes.
In the construction of the tangent to the triangle, the part that needs revision is D. Vance should have constructed all three altitudes instead of only constructing two altitudes.
What is a triangle?It should be noted that a triangle simply means a polygon that's has three sides. Also, a triangle has there's edges as well as vertices.
In this case, in order to construct a circle tangent to all three sides of the acute, scalene triangle LMN, it should be noted that the three altitudes have to be taken into consideration.
This wasn't the case in the step given by Vance has only two altitudes were considered. Therefore, this should be the change that is required.

What is the measure of angle x?
Answer:
46
Step-by-step explanation:
Because they are alternate, duh
Answer:
==> X = 46°
Step-by-step explanation:
Since 46° is vertically opposite to X
therefore, x = 46°
When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal.
Cost of 5kg of wheat is Rs. 91.50. What quantity of wheat can be purchased in Rs. 183? (Topic- Ration and Proportion)
The ratio between the weight of the wheat and the cost is 5:(91.50)
When multiplying both quantity by a same number, it is an equivalent ratio.
(Also call the quantity of wheat that can be purchased as x)
5:(91.50) = x:183
(5x2):(91.50x2) = x:183
10 : 183 = x : 183
-> x = 10
So, the quantity of wheat that can be purchased in Rs. 183 is 10kg.
You work in a department store and sell a dress that is on sale for $58.80. If the regular price of the dress is $98, what is the discount?
Answer:
The discount is 60%
Step-by-step explanation:
We can set up a proportion to solve for the discount percent. On the left I will put costs in dollars and on the right the percentage of the cost, with the regular price on the top.
-> Percents are divided by 100 to become decimals
[Start]
[tex]\frac{98}{58.8}=\frac{1}{x}[/tex]
[Cross-multiply]
98 * x = 1 * 58.8
98x = 58.8
[Divide both sides of the equation by 98]
x = 0.6
[Multiply both sides of the equation by 100 to get a percent]
The discount is 60%

Jesse wants to start driving himself to and from school each day. His parents want to know how much driving time would be involved, so Jesse surveyed 4 neighbors who live on his block and drive to his school. The data he collected is displayed in the table below. If asked how much time he will spend driving to and from school in a 5-day week, which would be Jesse’s BEST response based on the data he collected?
150 minutes
135 minutes
190 minutes
175 minutes
Answer:
175 minutes
Step-by-step explanation:
Add up the 8 different times then divide by 4 to get the average driving time for 1 day:
⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138
⇒ 138 ÷ 4 = 34.5 mins
Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:
⇒ 34.5 x 5 = 172.5 minutes
As 172.5 ≈ 175 minutes, the nest response is 175 minutes

A right square prism has a volume of 360 cubic units. Which could be the dimensions, in units, of the prism? Select three options.
The dimensions, in units, of the right square prism are 3 by 3 by 40, 2.5 by 12 by 12 and 3.6 by 10 by 10.
What is of volume of solid?
Volume of solid is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
The volume of a right square prism can be calculated using the following formula.
[tex]V=a^2h\\[/tex]
Here, (a) is the side length of the base and (h) is the height.
The right square prism has a volume of 360 cubic units. Lets check all the options, whose volume is equal to 360 cubic units.
The dimensions of the first option is 3 by 3 by 40. Thus, the volume of it,[tex]V=3^2\times40\\V=360\rm\; units^3[/tex]
The dimensions of the second option is 4 by 4 by 20. Thus, the volume of it,[tex]V=4^2\times20\\V=320\rm\; units^3[/tex]
The dimensions of the third option is 5 by 5 by 14. Thus, the volume of it,[tex]V=5^2\times14\\V=350\rm\; units^3[/tex]
The dimensions of the fourth option is 2.5 by 12 by 12. Thus, the volume of it,[tex]V=12^2\times2.5\\V=360\rm\; units^3[/tex]
The dimensions of the fifth option is 3.6 by 10 by 10. Thus, the volume of it,[tex]V=10^2\times3.6\\V=360\rm\; units^3[/tex]Hence, the dimensions, in units, of the right square prism are 3 by 3 by 40, 2.5 by 12 by 12 and 3.6 by 10 by 10.

The points wont be absolute on the line since they are decimals so you could gather 2 points like (27,162) and (32,141) and calculate for y which is y2-y1/x2-x1 but it would not give you the right answer so you would need to use linear regression using 3 values. First Calculate the sum of the x-values, then the y -values. Now sum the products of each data point and then, calculate the sum of the x-values squared and the y-values squared. Finally, count the number of data points you have. In this case we have three data points (N=3), then use the Number of points you have times the x and y sums you got from squaring and adding to get the slope.
