Answer:
(-1,-1)
Step-by-step explanation:
finding y
-6x + 5y = 1
+ (6x + 4y = -10)
---------------------------
9y = -9
y = -1
finding x
-6x + 5(-1) = 1
-6x - 5 = 1
+ 5 = +5
-6x = 6
x= -1
Answer:
Your answer is 15, 100% of the exam is 15 questions.
Step-by-step explanation:
60% x ? = 9
We need to do 9 divided by 60%
Which is actually 9 divided by 60/100.
Which is equal to; (100 x 9) divided by 6.
Which is then 900 divided by 60 which equals 15.
Answer: 15
4x³ - 6x² + 10x - 15
2x²(2x) - 2x²(3) + 5(2x) - 5(3)
2x²(2x - 3) + 5(2x - 3)
(2x² + 5)(2x - 3)
The answer is B.
