(-3, 1)
4x-9y=-21
+-4x-3y=9
-12y= -12
y=1
4x- 9(1)= -21
4x-9=-21
+9 +9
4x= -12
x=-3
Answer: 13 is c im pretty sure and 14 is a im think hope fully it helps
Step-by-step explanation:
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
It would be $45. The equation is 500×0. 06×1.5
The answer is $62.00
Explanation: If you take $48.50 times 6 you get $291 now subtract $291 from $663 you will have an answer of $372 that is how much the total of tables came to now divide 372 by 6 for the number of tables and you will be left with 62
