Answer:
x = -19/3 y = 10 write as an ordered pair (-19/3, -10)
Step-by-step explanation:
Step 1: 'Elimination' is done through adding or subtracting. You want to add the two equations together to get rid of one of the variables.
Since the x values have coefficients with opposite signs (-9 and 9), add the two functions together. The result is...
-2y = 20 { -9x + 9x = 0, so x is gone, 4y + (-6y) = -2y, 17 + 3 = 20 }
Step 2: Now solve for the remaining variable, in this case, 'y'
-2y = 20 (divide both sides by -2 to isolate the variable)
y = -10
Step 3: Plug the value for 'y' into one of the original equations to find 'x'
-9x + 4(-10) = 17 ('y' becomes -10)
-9x - 40 = 17 { 4(-10) = -40 } (now add 40 to both sides)
-9x = 57 (divide both sides by -9 to isolate 'x' )
x = -57/9 (now reduce, both are multiples of 3, so divide 3 out)
x = -19/3 ( -57/3 = -19, 9/3 = 3 )
I would look at the common factors for this one. so let's factor them
36 = 2 * 18
36 = 3 * 12
36 = 4 * 9
48 = 2 * 24
48 = 3 * 16
48 = 4 * 12
48 = 6 * 8
if we look the greatest common factor they have would be 12. But if they both had 12 then corn would oy have 4 in each row. But if we do the smallest amount of rows then we would have more cans as the owner wants. So if we madeniy 2 rows then corn would have 24 in each row. that wpuld.be the most possible
Answer:
PQ ≈ 14.14 units
Step-by-step explanation:
calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = P (0, 4 ) and (x₂, y₂ ) = Q (10, - 6 )
PQ = 
= 
= 
= 
≈ 14.14 units ( to 2 dec. places )
Answer:
y=-4/23
im not sure i didn't check (might be wrong)
Step-by-step explanation:
4x - 5y = -28
-3x - 2y = 10
then make x the same
So
12x-15y=-84
-12x-8y=80
then its left with
-23y=-4
y=-4/23
find x by entering y into -3x - 2y = 10 and solving
