*here is step by step*
(Remember to add the 'x' to the slope)
-4x+6y=16
6y=4x+16
y= 4/6x + 2.66
The complete answer is:
y= 2/3x + 2.66
Answer:
17. is 20 18. is 9hours 19. is 60mph
you get this by doing 100 divided by 5 which equals 20 360 divided by 40=9 and 420 divided by 7 =60
A company is selling books. It has to pay $500 to start printing the books, and once they have done that, the books sell at $14.99 each. How many books must they sell to make a profit?
First we would model an equation. X will be the amount of books sold, and Y will be profits (in dollars obv). They had to pay $500 before they could start selling, so we must account for that too.
This equation would be

because for every book sold, X increases by 1, increasing Y by 14.99
The answer would be 34 books sold in order to turn a profit. (500/14.99=
Answer:

Step-by-step explanation:
We can directly substitute y of the first equation to the second equation.
-2x - 1 = 3x - 16
5x = 15
x = 3
Substituting back to any of the two equations, we get y = -2(3)-1 = -7. If you check with the second equation, y = 3(3)-16 = -7 as well.
Therefore
.
So what you do is you want to multiply
3.8 × 50=190km
