Answer:
C none of the above
Step-by-step explanation:
A negative divided by a negative is a positive
- ( l/ -m) = + l/m
A is negative
B is negative ( negative negative negative is negative)
Answer:
(a + 8)(a + 1)
Step-by-step explanation:
We know that the first term is squared, so we can put it out like this:
a * a
The third term has to be separated so that the sum of the two factors is the coefficient of the second term, 9.
8 = 4 * 2 (does 4 +/- 2 = 9? nope, we can't use that)
8 = 8 * 1 (does 8+/- 1 = 9? yes, when 8 + 1)
So the factor is a + 8 and a + 1.
Put this together and (a+8)(a+1)
4k-7=2k+3
-2k. -2k
2k-7=3
+7. +7
2k=10
2÷2 2÷10
k=5
4(5)-7=13
Answer D
Answer:
y = -5/2x + 1
Step-by-step explanation:
y=mx+b
m is slope
b is y intercept
= 1

1/4 * 1/8 * -1024
= 1 / ( -32)
= -1/32
