There are two of them:
1). (n * a) means n + n + n + n + n + n + n + . . . 'a' times.
2). (n * a) also means a + a + a + a + a + a + a + a + . . . 'n' times.
Answer:
A) y = x^2 -1
B) -y = 2x^2 +1 We multiply B) by -1
B) y = -2x^2 -1
We can then say x^2 -1 = -2x^2 -1
3 x^2 = 0
x = 0
************* Double-Check: ******************
Equation A) y = -1 and
Equation B) y = -1
Step-by-step explanation:
Answer:
There will be 9 groups of 8 and 1 group of 6.
Step-by-step explanation:
78/8 = 9.75
This means there will be 9 groups of 8.
