what is the solution to this system of equations (Use the elimination method by multiplying the first equation by 3.) 2x+y=20 6x
user100 [1]

Answer:

(7, 6)

Step-by-step explanation:

multiply first eq. by 3 to get 6x - 3y = 60

now do

6x + 3y = 60

- 6x - 5y = 12

--------------------

8y = 48

solve for y: y = 6

with this y value, plug it in to the first equation (easier to solve) and get 2x + 6 = 20

solve for x and get x = 7

so ans is (7, 6)

In a field, dry fodder for the cattle is heaped in a
ipn [44]

Answer:

volume of fodder=1/3pie R^2h=\frac{1}{3} *\frac{22}{7} * (3.6)^2 *2.1=28.51m^3

l^2=r^2+h^2

l^2=(2.1)^2+(3.6)^2

l^2=4.441+12.96=17.37

l=\sqrt{17.37}=4.17m

minimum area of polythene to cover fodder=pieRl=\frac{22}{7} *3.6*4.17=47.18m^2

the volume of fodder is 28.51m^3 and minimum area of polythene to cover fodder in the  rainy seasonv47.18m^3

If the endpoints of the diameter of a circle are (9, 4) and (5, 2), what is the standard form equation of the circle?
sattari [20]
The standard forrm equation of the circle is (x-h)² + (y-k)² = r²
where h,k : x,y-coordinate of the center
           r : radius of the circle
Get the center of the circle : h = (x1 + x2)/2 = (9+5)/2 = 7
                                             k = (y1 + y2)/2 = (4+2)/2 = 3
=> the center is (7,3)
Because the given information gave 2 endpoints so we can choose one of these, then use the distance formula to get the radius
                                            r = √(x1 - h)² + (y1 - k)²
                                            r = √(9 - 7)² + (4 - 3)²
                                            r = √2² + 1² 
                                            r = √5
Finally, the equation of the circle is (x - 7)² + (y - 3)² = (√5)²
                                                        (x - 7)² + (y - 3)² = 5
