Answer:
Step-by-step explanation:
The given system of equations :
Multiply equation (1) with 3 and equation (2) with 2 , we get
Now subtract equation (4) from equation (3), we get
Substitute the value of y in equation (1), we get
Hence, the solution of the system : (x,y)=(2,6)
Now, consider and substitute the value of x and y , we get
The solution to the equation is x - y = -4
Given data ,
To solve the system of equations, we can use the method of substitution or elimination. Let's use the method of elimination:
Multiply the first equation by 3 and the second equation by 2 to make the coefficients of x in both equations equal:
(3)(2x-3y) = (3)(-14)
(2)(3x-2y) = (2)(-6)
Simplifying these equations gives:
6x-9y = -42
6x-4y = -12
Now, subtract the second equation from the first equation:
(6x-9y) - (6x-4y) = (-42) - (-12)
-5y = -30
Divide both sides by -5:
y = 6
Substitute this value of y back into one of the original equations, let's use the first equation:
2x - 3(6) = -14
2x - 18 = -14
2x = 4
x = 2
Now , the value of x - y is given by
A = x - y
A = 2 - 6
A = -4
Hence , the equation is solved

any two points is . . .
square root of [ (difference in their x-values)² + (difference in their y-values)² ].
Your two points are (-9, 6) and (-3, 9).
The difference in their x-values is 6 .
The difference in their y-values is 3 .
The distance between the points is . . .
square root of [ (6)² + (3)² ] = √(36 + 9) = √45
a^2+b^2=c^2
so to find a you subsitute (x₁-x₂) and for b subsitute (y₁-y₂)
we want to find c
so
(-9-(-3))^2+(6-9)^2=c^2
(-9+3)^2+(6-9)^2=c^2
(-6)^2+(-3)^2=c^2
36+9=c^2
45=c^2
square root both sides
√45=c=distance
√45=3√5 in other words 3 times √5
answer is 3√5

length of the needle: 20 cm
angle 100°
We need to solve for the length of an arc to get the distance the needle has traveled.
Length of an Arc = n°/360° * 2πr
Length of an Arc = 100°/360° * 2 * 3.14 * 20cm
Length of an Arc = 0.28 * 125.6 cm
Length of an Arc = 35.17 cm
Answer: 100(pi)/9
Step-by-step explanation:
We use the equation (theta/360)(2)(pi)(r)
Theta = 100 (100 degrees of a 360 degree circle)
r = 10 (not 20 because that is the whole needle, we need half of 20 for the radius)
Plugging this in: 100/360 (2)(pi)(10)
2,000(pi)/360
Divide by 20 to simplify:

Step-by-step explanation:
The equation of a line passing from points (p,q) and has slope m is given by :-
Given : Slope of line {m} = b
Point through which line is passing : (p,q) =(a,b)
The equation of a line passing from points (a,b) and has slope m is given by :-
y-b=b(x-a)
==>y=bx-ab+b

Model one red: 6x2x12= 144ft cubed
blue:6x4x2= 48ft cubed
Model 2 red: 6x2x10= 120ft cubed
blue: 6x6x2=72ft cubed
You don't need to break it apart. As you can see in my first part, I multiplied the width by the length of the entire bed then afterwards I subtracted the part of the bed that's "missing" (the hole).
Hope this helped
2ft,4ft,6ft then you will multiply all your heights with your bases 2ft x 6ft=12ft squared 2
4ft x 6ft=24ft squared 2
6ft x 6ft=36ft squared 2
why you square is because you no what im going to show you all i know about this subject and hope it can help your formula
where...
base 1=length of base 1
base 2=length of base 2
height=perpendicular distance
between base 1 and base 2
formula example 1
A=(b1+b2)h
A=(2+4)2fraction of 2 underneath
A=6 x 2 fraction of 6 underneath
which equals A=6cm squared 2 in a rectangular prism there is always 2 opposite sides that have the same area,
to find the surface area, the sides, multiply by LxW and multiply by 2.
since there are 3 sets of sides we have to make 3 calculations and add the together.
LxW is one set
LxH is another set
WxH is the third set
example: set 1=(2)x(8)x(5)set 1 surface area is 80cm squared
set 2=(2)x(8)x(3)
set 2 surface area is 48cm squared
set 3=(2)x(5)x(3)
set 3 surface area is 30cm squared
to find the total surface area, add the numbers together.
the total surface area of the cube is 158cm squared
and your volume of a rectangular prism is (whi) which means
w=width
h=height
l=length
the entire volume of a garden bed is 72ft squared 2 that is in the cse of the garden bed we are solving i got that answer by multiplying (whi) then add my calculation of my answers with my multiplication answers and said ok well
12+24+36= 72ft squared 2
so know we can move on to tori
i was going to help you with tori but it only shows stuff about bethany and the garden bed i guess to question 6. that you asked i would say now 1 because u didnt show what it was for the calculations and 2 u cant solve somthing thats not there :) i hope i could help :)
