Answer:
infinite number of solutions
Step-by-step explanation:
Work with the second equation. Subtract 8x from both sides.
- 4y + 8x - 8x = -8x - 12 Collect like terms.
-4y = - 8x - 12 Divide by - 4
-4y/-4 = - 8x/-4 - 12/-4
y = 2x + 3
That is exactly the same line as the first given. There is an infinite number of solutions.
the answer is 10.
place your index fingers on the 4 & the 9 then move in toward the 10 the number in the middle is 10.
Answer:
3 hour and 30 minutes
Step-by-step explanation:
Divide
Sin(α+β)=sin(α)cos(β)+cos(α)sin(β)
sin(α-β)=sin(α)cos(β)-cos(α)sin(β)
First, you multiply 42 by .15 which you get $6.30
Then, you subtract $42 by $6.30 which you get the answer: $35.70
