B= 0, -2
C= -2, -1
Step-by-step explanation:
originally the coordinates are x, y but if it is reflect over the line y = - x which will now turn your coordinates to (-y, -x)
Answer: The expression which represents the condition described is given as 
Step-by-step explanation:
Since we have given that
Amount that Molly owes her brother = $300
Let the number of hours she worked as a checker be x
Cost of per hour = $10
Amount she get after doing work for x hours is given by

Rate of tax are taken out = 80%
So, amount she left with is given by

So, Molly plans to repay her brother half of what she earns is given by

According to question,

So, the expression which represents the condition described is given as

Answer:
81
Step-by-step explanation:
(9x - 4)(9x + 4) = ax² - b
81x² - 36x + 36x - 16
= 81x² - 16
=> a = 81
Answer:
hi yayyyyyyyyyyyayayayaya
Step-by-step explanation:
<h3><u>The value of a is equal to 0.93.</u></h3>
-6(7a - 4) = 3(a - 7) + 3
Distributive property.
-42a + 24 = 3a - 21 + 3
Add 42a to both sides.
24 = 45a - 21 + 3
Combine like terms.
24 = 45a - 18
Add 18 to both sides.
42 = 45a
a = 0.93
