Answer:
A)Her statement is not correct because a negative times a negative is a positive but if you times it by negative again then it will be negative again not positive
B)(–3) – (–5) = (–3) + 5 = 2
c)Yes she is correct
5 – (–3) = 5 + 3 = 8
(–3) – (–5) = (–3) + 5 = 2
Step-by-step explanation:
(-1,-1)(-3,-3)
slope = (-3 - (-1) / (-3 - (-1) = (-3 + 1) / (-3 + 1) = -2/-2 = 1
Answer:
8.5% (you can approximate that, that's the exact number and it isn't too funky)
Step-by-step explanation:
Percentage is out of 100, and over here we see that 200 is 2 times the amount of 100. So that means that if we divide 200 by 2, we get 100, which means we also divide 19/2 to get 8.5. That means, out of 100 light bulbs, 8.5 of them burned out. This is really easy to convert because the percentage is already out of 100, so you just make 8.5 into a percent which is 8.5%
Let me know if you have any questions.
Step-by-step explanation:
82 + 16 = 98
Expression A: 122 - 82 = 40
Expression B: 2(62) + 23 = 147
Expression C: 102 - 32 = 70
None of them has the same value as 82 + 16.
