Answer:
i am good so nah but free pionts tanks
Step-by-step explanation:
(3, -2)
Step-by-step explanation:
y = -2x + 4
-x + 3y = -9
-x + 3 (-2x + 4) = -9
-x + -6x + 12 = -9
-7x = - 9 – 12
-7x = - 21
X = 3
We substitute x with 3 to evaluate y;
-3 + 3y = -9
3y = -6
y = -2
Elimination Method;
y = -2x + 4
-x + 3y = -9
We arrange the equations for substitution;
2x + y = 4
-x + 3y = -9
We multiply the first equation with 3 so we can substract one variable to zero;
3 (2x + y = 4)
= 6x + 3y = 12
Then we subtract the two;
6x + 3y = 12
-x + 3y = -9
7x = 21
x = 3
We evaluate y by substitution x with 3 in one of the equation;
-x + 3y = -9
-3 + 3y = -9
3y = -6
y = -2
The final answer expressed as a coordinate point is;
(3, -2)
Answer:
It would be 828 inches cubed
Step-by-step explanation:
Because the boxes on top and bottom are both 6x8x6 and the middle portion is 6x7x6
6x8x6=288
6x7x6=252
288+288+252=828
Answer:
Answer of 1+2+4+6+7+9+1+9+0+8+7+56-12=98
Answer:
3334650.54 euros
Step-by-step explanation:
We can calculate the area of the triangle knowing its sides by means of Heron's formula:
A = 
Where p is the semi-perimeter is equal to:
now, we replace:
p = 518.5
now, we replace this value and we are left with:
A = 
A = 50440.94 m^2
Now to know the price, we multiply by the price of the square meter:
50440.94 * 66.11 = 3334 650.54
In other words, the value of the parcel is 3334 650.54 euros
