The solution for the given system of equations x + 8y = -37, 4x + 8y = -52 is
Given,
System of equations as,
x + 8y = -37
4x + 8y = -52
We have to solve this by using the inverse of coefficient matrix of the equivalent matrix equation.
That is,
Now we can solve the equations.
Here we have,
x + 8y = -37
4x + 8y = -52
Now in matrix form,
A X B
We know that,
Therefore,
Then,
That is

Solve The System Of Equations By Using The Inverse Of The Coefficient Matrix Of The Equivalent Matrix Equation.
x + 8y = -37
4x + 8y = -52
X = number of bags needed
The equation that will be set up is
10,000/20 = 140,000/x
cross multiplying gives
10,000x = 20*140,000
10,000x = 2,800,000<span>
now divide both sides by 10,000 to fully isolate x
</span>10,000x = <span>2,800,000
</span>10,000x<span>/10,000</span> = 2,800,000/10,000
x = 280
So you'll need 280 bags
Hello :
<span>note :
an equation of the
circle Center at the w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : </span><span>x²+y²-16x+6y+53=0
(</span>x²-16x) +( y²+6y ) +53 = 0
(x² -2(8)x +8² - 8²) +(y² +2(3)x -3²+3² ) +53=0
(x² -2(8)x +8²) - 8² +(y² +2(3)x +3²)-3² +53=0
(x-8)² +( y+3)² = 20
the center is : w(8,-3) and ridus : r = <span>√20</span>
Answer:
The graph goes with the third chart
Step-by-step explanation:
Y starts at 3 and then goes up to 4,5, and then 6 while x starts at 0 and goes up to 1,2, and 3
