Answer:
The equation of a line in point-slope form is.
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯∣∣aay−y1=m(x−x1)aa∣∣−−−−−−−−−−−−−−−−−−−−−−
where m represents the slope and (x1,y1) a point on the line.
To calculate the slope use the gradient formula
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯∣∣∣aam=y2−y1x2−x1aa∣∣∣−−−−−−−−−−−−−−−−−
where (x1,y1) and (x2,y2) are 2 coordinate points.
here the 2 points are (-3 ,4) and (0 ,3)
let (x1,y1)=(−3,4) and (x2,y2)=(0,3)

Answer:
(9, 12)
Step-by-step explanation:
Given that :
u = (3, 4)
3u = 3(3, 4)
3u = 3(3, 4) = (9, 12)
Hence, 3u = (9, 12)
Answer:
<9, 12>
Step-by-step explanation:
Multiply X and Y values by the number of U there are.
u= <3,4>
2u=<6,8>
3u= <9,12> Multilpy By 3 to get 3u
Your answer is <9,12>.

A family wants to remodel a house and spend at most $135,000 total for the entire project. a)If the builder wants to make a 15% profit on the value of the project, what is the largest amount the family can spend on hard costs (materials, labor, engineering, designing, permits) to be able to pay the builder his profit while staying under the $135,000 budget? b)What is the builder's profit? (Hint: You cannot simply take 15% of $135,000 because the $135,000 includes the builder's profit. Just like in our commission problems, you don't make commission on commission. The percentage is applied to the value of goods and services provided.)

i am thinking of a number i multiply by 14 qand add 12 i get the same answer if i multiply by 5 and add 246
Answer:
x = the unknown number = 26
Step-by-step explanation:
Let
x = the unknown number
i multiply by 14 qand add 12
(x * 14) + 12
= 14x + 12
i get the same answer if i multiply by 5 and add 246
(x * 5) + 246
= 5x + 246
Equate both equations
14x + 12 = 5x + 246
14x - 5x = 246 - 12
9x = 234
x = 234 / 9
x = 26
x = the unknown number = 26
Which of the following is not a factor of the polynomial p(x) = x³ - 23x² + 142x - 120?
Options :
A(x - 1)
B(x - 10)
C(x - 5)
D(x - 12)
no spam answers and explain how you got the solution.
Answer:
The correct answer is C- (X-5)Solution
Given -
polynomial p(x) = x³ - 23x² + 142x - 120
Now see the coefficients
coefficient of x³ is 1 x² is -23 x is 142 and then -120
when you'll add this coefficients
i.e.
1-23+142-120=0
When sum of the coefficient turn out 0 then x = 1
using x=1, x-1 = 0
devide the given polynomial p(x) = x³ - 23x² + 142x - 120 by x-1 you'll get rest two factors hence

The graph of y = ½ x2 − x − 4 is shown below. What are the zeros of the quadratic?
Answer:
x = - 2, x = 4
Step-by-step explanation:
The zeros are the values of x on the x- axis where the graph crosses
The graph crosses the x- axis at (- 2, 0 ) and (4, 0 )
Then the zeros are x = - 2 and x = 4

If line segment AB,A(9,3) and B(-6,-9), what scale factor was used to dilate if new line is at A'(3,1) and B'(-2,-3)?
Answer:
The scale factor is 1/3
Step-by-step explanation:
Here, we want to get the scale factor used in dilating the original segment
As we can see;
(9,3) turned to (3,1)
looking at this , we can see that both coordinate values were divided by 3
So what this mean is that the particular scale factor used is reduction by 1/3
This is the case with the other point as (-6,-9) turned to (-2,-3)
6c^2 - 5d + 8 when c =5 and d=4
Answer:
138
Step-by-step explanation:
First, we can simply replace the variables with their numerical values.
Whenever you see a number with a letter (variable) in front of it, this means to multiply.
c=5 and d=4
6 × 5^2 - 5 × 4 + 8
Since there are multiple operations in this expression, we must use PEMDAS.
ParenthesisExponentiation (exponents)Multiplication/Division (Solve whichever comes first)Addition/Subtraction (Solve whichever comes first)--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Now, we can apply the operations.
There are no parenthesis.
In this expression, exponents are present.
6 × 5^2 - 5 × 4 + 8
6 × 25 - 5 × 4 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is multiplication.
6 × 25 - 5 × 4 + 8
150 - 5 × 4 + 8
150 - 20 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is subtraction.
150 - 20 + 8
130 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is addition.
130 + 8
158
Therefore, 6 × 5^2 - 5 × 4 + 8 = 138.

Answer:
wheres the question ?
Step-by-step explanation:
Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = -6x - 8
Step-by-step explanation:
Two points on this line are (-3, 10) and (0, -8). Moving from the first to the second, we see that x increases by 3 and y decreases by 18. Thus, the rise and run are -18 and 3 respectively, so that the slope of this line is m = -6.
Adapt the slope-intercept form y = mx + b to this particular situation. Recognize that the given (0, -8) is the y-intercept and that the slope, m, is -6.
The equation of this line is thus
y = -6x - 8

How much money will Louis save on the total cost because of the markdown?

Part ACalculate sale price and add sales tax:
20% off $339 add tax ⇒ $339*0.8*1.085 = $294.25 ≤ $30015% off $310 add tax ⇒ $310*0.85*1.085 = $285.90 ≤ $30025% off $365 add tax ⇒ $365*0.75*1.085 = $297.02 ≤ $30020% off $300 add tax ⇒ $300*0.8*1.085 = $260.40 ≤ $300Each price is acceptable as less than $300

EASY- Han has to build the figure below, which will serve as a counterweight, for his robotics project. Find the VOLUME of the finished object assuming it is empty inside.
Given:
A combined figure of a triangular prism and a cuboid.
To find:
The volume of the finished object assuming it is empty inside.
Solution:
From the given figure it is clear that the dimensions of the cuboid are 6 cm, 8 cm and 5 cm.
So, the volume of the cuboid is:
[tex]V_1=length\times width\times height[/tex]
[tex]V_1=6\times 8\times 5[/tex]
[tex]V_1=240[/tex]
The volume of the cuboid is 240 cubic cm.
The area of a triangle is:
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Thus, the base area of the triangular prism whose base is 8 cm and height 4 cm, is:
[tex]B=\dfrac{1}{2}\times 8\times 4[/tex]
[tex]B=16[/tex]
The volume of a triangular prism is:
[tex]V_2=Bh[/tex]
Where, B is the base area and h is the height of the prism.
The base area of the triangular prism is 16 square cm and the height is 5 cm. So, the volume of a triangular prism is:
[tex]V_2=16(5)[/tex]
[tex]V_2=80[/tex]
Now, the volume of the given figure is:
[tex]V=V_1+V_2[/tex]
[tex]V=240+80[/tex]
[tex]V=320[/tex]
Hence, the volume of the finished object is 320 cubic cm.
