Y = -7x + 2
y = 9x - 14
-7x + 2 = 9x - 14
14 + 2 = 9x + 7x
16 = 16x
1 = x
y = -7x + 2
y = -7(1) + 2
y = -7 + 2
y = -5
solution is : (1,-5) <==
If the question is y = blank(x) + blank (I can’t see the left of the equation
Then the answer is y = 2x + -4
Answer:
The correct option is B
(-1)(1/2)(-1)(1)
Step-by-step explanation:
First thing to notice is that there is are two brackets with negative values, which means that the result must also be positive (or have two brackets with negative values).
Looking at the options, we can screen out options A and D, they have three brackets with negative values, and can't be chosen.
It is now between options B and C.
Option B, by inspection is simply 1/2
Option C is 12/4 = 3
The problem itself is 12/35
12/24 = 1/2
12/36 = 1/3
Since 12/35 is about 1/3, it is closer to 1/2 than 3, so 1/2 is the best option.
Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>It can be rewritten as:</u>
- v(d) = 2^d, where d- number of divisions
<u>If number of divisions is 8, then:</u>
- v(8) = 2^8 = 256 virus cells
Correct choice is B
