Answer:
(5, - 6 )
Step-by-step explanation:
Given the 2 equations
- 8x - 10y = 20 → (1)
- 8x - 6y = - 4 → (2)
Multiply (2) by - 1
8x + 6y = 4 → (3)
Add (1) and (3) term by term to eliminate the x- term, that is
- 4y = 24 ( divide both sides by - 4 )
y = - 6
Substitute y = - 6 into either of the 2 equations and solve for x
Substituting into (1)
- 8x - 10(- 6) = 20
- 8x + 60 = 20 ( subtract 60 from both sides )
- 8x = - 40 ( divide both sides by - 8 )
x = 5
solution is (5, - 6 )
Answer:
1,844,580,200,000,000 = 1.8445802×10^15
Step-by-step explanation:
31^3 x 12^10
31^3 = 31 x 31 x 31
12^10 = 12 x 12 x 12 x 12 x 12 x 12 x 12 x 12 x 12 x 12
31^3 = 29791
12^10 = 61917364224
29791 x 61917364224 = 1,844,580,200,000,000 = 1.8445802×10^15
Answer is
Z= -1
Y= 3
X= -1 I’m sure it’s that
Answer:
Puts the dots where the A,B,C,D dots are and move them 5 units to the right.
Example:
Original place
A=(2,5)
Moved 4 units to the right:
A'=(6,5)
Here are some tips:
Up= Y value goes up
Down= Y value goes down
Right= X value goes up
Left X value goes down
