Answer:
{x,y,z} = {-18,4,2}
Step-by-step explanation:
Solve equation [2] for the variable x
x = -10y + 2z + 18
Plug this in for variable x in equation [1]
(-10y+2z+18) + 9y + z = 20
- y + 3z = 2
Plug this in for variable x in equation [3]
3•(-10y+2z+18) + 27y + 2z = 58
- 3y + 8z = 4
Solve equation [1] for the variable y
y = 3z - 2
Plug this in for variable y in equation [3]
- 3•(3z-2) + 8z = 4
- z = -2
Solve equation [3] for the variable z
z = 2
By now we know this much :
x = -10y+2z+18
y = 3z-2
z = 2
Use the z value to solve for y
y = 3(2)-2 = 4
Use the y and z values to solve for x
x = -10(4)+2(2)+18 = -18
The graphs have precisely the same shape, but that of g(x) is that of f(x) translated 4 units DOWN.
Answer:
D. 35x+111y
add the X’s together and then add the Y’s!
a) The fire burnt 840.6 square miles
b) The fire burnt 16.8 tempe
Step-by-step explanation:
1 square mile = 640 acres
a) to find how many square miles did the fire burn:
Total area the fire burn = 538000 acres
1 square miles = 640 acres
Concert the acres into square miles
538000/ 640 = 840.6 square miles
The fire burnt 840.6 square miles
b) 50 square miles= 1 temperatures
The no. Of tempe the fire burn = 840.6/50
= 16.8 tempe
The fire burnt 16.8 tempe
