Answer:
-3x-5 x-4 I this work good luck
Answer:
-(3x-5) (x-4)
Step-by-step explanation:
-3x^2+17x-20
Factor -1 out of -3x^2
-(3x^2)+17x-20
Factor -1 out of 17x
-(3x^2)-(-17x)-20
Rewrite -20 as -1(20)
-(3x^2)-(-17x)-1(20)
Factor -1 out of -(3x^2)-(-17x)
-(3x^2-17x)-1(20)
Factor -1 out of -(3x^2-17x)-1(20)
-(3x^2-17x+20)
Factor.
-((3x-5)(x-4))
Final Anwser:
-(3x-5) (x-4)
Answer:
37.75⁰
Step-by-step explanation:
Height of the building = 18 feet (vertical height)
Height of the ladder = 25 feet (Hypotenuse)
We solve this using tan θ =
therefore θ = tan⁻¹ ()
θ (Angle of elevation) = 37.75⁰
The required value of x is 20.
A proportion is an equation in which two ratios are set equal to each other. In simple words, equivalent fraction are called as proportions.
Now the given equivalent ratios is,
3/12 = 5/x
Cross multiply the ratios we get,
3*x = 5*12
Solve them we obtain,
3x = 60
now dividing both side by 3,
3x/3 = 60/3
Solve them we obtain,
x = 20
So the value of x = 20.
Hence, for equivalent ratios 3/12 and 5/x the valueof x is 20.

Part A
Go to your math tools and open the Graph tool to graph the two sets of equations. To see where the two lines intersect, change the scale so that the x-axis goes from 0 to 30 and the y-axis goes from 0 to 12. Paste a screenshot of the resulting graph in the answer space.
Part B
At which point do the lines intersect?
Part C
Do the coordinates of the point of intersection satisfy both equations simultaneously?
Answer:
Part-A: refer to the attachment
Part-B: (10,11)
Part-C: yes
step-by-step explanation:
Part-A:
refer to the attachment
(I used a online graphing calculator to graph the equations which made the work easy)
Part-B:
When two lines share exactly one common point, they are called the intersecting lines and thepointis called thepointof interception
Looking at the graph,we can understand that the two lines share a common point at (10,11),
hence,
The lines intercept at the point (10,11)
PartC:
well, to find the answer of this part, we can consider doing equality check by substituting the value of the point we got.
The point (10,11) means that the left and right hand side of both of the equations i.e are equal when x and y equal to 10 and 11 respectively.
So let's justify the points:
equation-1:
substitute the value of x and y respectively:
simplify addition:
equation-2:
substitute the value of x and y respectively:
simplify addition:
so,
Yes,the coordinates of the point of intersection satisfy both equations simultaneously
