Answer:
A. 8x - 9y = -23
Step-by-step explanation:
(-4,-1) and (1/2,3)
We write the equation in slope intercept form y=mx+b
then we convert it into standard form
m is the slope and b is the y intercept
(-4,-1) and (1/2,3)
To find out b we plug in (-4,-1) and slope m value in y = mx+b
-1 = (8/9) (-4) + b
Add 32/9 on both sides
Take common denominator 9
So equation y = mx + b becomes
Standard form is Ax + By = C
To get standard form , multiply the whole equation by 9
9y = 8x + 23
Subtract 8x on both sides
-8x + 9y = 23
Multiply the whole equation by -1
8x - 9y = -23
The ratio is 15:24, which simplifies to 5:8

Answer:
True
Step-by-step explanation:
We know that the debt-to-GRD ratio is 84% and we also know that debt-to-GDP ratio of 100% means that a country's debt is equal to its gross domestic product. The higher the ratio, the less likely a country will be able to repay its debt.
For that reason if a country debt-to-GRD ratio is 84% then, the country is producing more than it's borrowing.
Answer:
Additive inverse is (7y² - x²y + 3xy + 7x²).
Step-by-step explanation:
Let the additive inverse of the given polynomial be Y.
Therefore as per definition of additive inverse of any polynomial the addition of a polynomial and additive inverse of any polynomial is always zero.
So Polynomial + additive inverse polynomial = 0
(-7y² + x²y - 3xy - 7x²) + Y = 0
Y = -(-7y² + x²y - 3xy - 7x²) = (7y² - x²y + 3xy + 7x²)
So the additive inverse of the polynomial will be (7y² - x²y + 3xy + 7x²).
