Find the values of x, y, and z in the
parallelogram. Note that the figure is not
drawn to scale.
Step-by-step explanation:
we know that sum of all angles of a triangle is 180°
so, angle N + angle O + angle M = 180°
=> (-5b+16)+(-b+8)+(-9b-9) = 180°
=> -5b+16-b+8-9b-9 = 180°
=> -15b+15 = 180°
=> -15b = 180-15
=> -15b = 165
=> b = -165/15
=> b = -11
angle N => -5(-11)+16
=> 55+16 => 71
angle O => -(-11)+8
=> 11+8 => 19
angle M => -9(-11)-9
=> 99-9

The solutions to a certain quadratic equation are x= -4 and X = 3. Write the equation in standard form below.
[blank] +x [blank] [blank] = 0
Answer:
x² + x - 12 = 0
Step-by-step explanation:
If x = -4 and x = 3 are solutions to a quadratic equation, then
(x + 4)(x - 3) = 0
Expand the brackets: x² - 3x + 4x - 12 = 0
Combine like terms: x² + x - 12 = 0

Car A is traveling west at 40 mph and car B is traveling north at 55 mph. Both are departing from the intersection of two roads at the same time. Write a function representing the distance between the two cars in terms of the time , in hours, that has elapsed since the cars left the intersection.
Answer:
[tex]5\sqrt{185}t[/tex]
Step-by-step explanation:
after time t (hr), the distance between A and starting point is 40t
the distance between B and starting point is 55t
These two distances are perpendicular to each other, so
the distance between A and B is

Medians bisect eachother at centroid in ratio 2:1

UY=UZ
So
YZ=2(66)=132Apply Pythagorean theorem
[tex]\\ \tt\hookrightarrow VY^2=XS^2-VS^2=80^2-48^2=6400-2304=4096\implies VY=64[/tex]
Answer:
XS = 80
YZ= 132
VY = 64
Step-by-step explanation:
Firstly, SU is a perpendicular bisector
so, UV= UZ and YZ = 2(66) = 132
Each median bisect each other at centre with the ratio 2 : 1
therefore ZS = 80 = XS
now , by using P.G.T
VY² = XS²-VS²
=> 80²-48²
=> 6400-2304
=> 4096
=> √4096
=> 64
VY = 64

Answer:
I'm certainly late, but it took me a while to figure this one out so I want to leave an answer.
A=-5 B=2 C=19 D=-2
Step-by-step explanation:
I looked back at the video and actually tried to pay attention and the way to figure these problems out is set up all of the degrees of x in an equation. So, take all of the coefficients that are attached to an x^3, and set them up equal to each other. This makes -5=A, which is the first answer. Repeat for x^2 and you have B=2. For x, it becomes 9=2A+C. A is equal to -5 (from the x^3), so you can substitute and get c=19. Repeat for the x^0 term (the constants), and you get 2=2B+D. Plug in the value for B, 2, and get 2=4+D, which then becomes D=-2. That's how you get the answer and I hope this helps somebody.
The values are A=-5, B=2, C=19 and D=-2
What is partial fraction?Partial fractions are the fractions used for the decomposition of a rational expression. When an algebraic expression is split into a sum of two or more rational expressions, then each part is called a partial fraction. Hence, basically, it is the reverse of the addition of rational expressions.
Given:(-5x³+2x²+9x+2) / x²+2 =(Ax + B)/x²+2 + (Cx + d)/x²+2 .......(1)
First, we have to perform the long division as follows
The long division gives
(-5x³+2x²+9x+2 )/ x²+2= ( -5x+2)+ (19x-2)/ x²+2
Now, we have to find the partial fraction for (19x-2)/ x²+2
But, as denominator cannot be factored, So no partial fraction can be calculated.
Thus, (-5x³+2x²+9x+2 )/ x²+2= ( -5x+2)+ (19x-2)/ x²+2
Comparing it with equation (1), we get
Hence, A=-5, B=2, C=19 and D= -2
