Answer:
4 Can I have brainiest me trying to level up
Step-by-step explanation:
Let's make the parenthesis go bye
8-4
so it would be 4
3. The correct answer is 2) 3m² - 6.
(2m² + 3m - 4) + (m² - 3m - 2) Given
2m² + m² These numbers are like terms, because they both end in m².
3m² Since m² can also be written as 1m², and 2 + 1 = 3, this is the sum of 2m² and m² (1m²).
3m + (-3m) These numbers are like terms, because they both end in m. -3m is negative because it was being subtracted.
0 Since we're adding a negative, it's the same as subtracting something. 3m - 3m is 0.
-4 + (-2) These numbers are like terms, because they are both simple integers with no variable. Once again, we're adding a negative because it was being subtracted.
-6 -4 + (-2) is the same as -4 - 2, which is -6. Remember that when you're subtracting from a negative, the number seems to become larger. For instance, 1 - 1 is 0, but -1 - 1 is -2.
3m² - 6 Put all of the terms together. We don't have to write out 0, because 0 is the same as nothing.
5. This one is a bit unclear, but I think that the correct answer is 2) II and IV. The slope formula can be written as y = mx + b, where m is the slope and b is the y-intercept, or the place where the line crosses the y-axis. In this equation, b is 2, which is a positive number, so the y-intercept shifts upward. This means that the answer is either 2 or 3. As for |x - 6|, the way this is written makes the equation somewhat confusing. I believe that the bars are meant as absolute value bars, which, put simply, turn negatives into positives. This means that this part is x + 6, so the line shifts to the right. However, if they were intended as parentheses, the line would shift to the left, because we're subtracting 6 from x. I'm almost certain those were intended as absolute value bars, though, so I think that the answer is 2.
Hope this helps!
Answer:
6 days ; 2300 calories
Step-by-step explanation:
Given the following :
Current consumption :
Simba = 1520 calories per day
Increases by 130 calories per day : After d days ;
S(d) = 1520 + 130d
Where ; d = number of days
Cuddle = 3380 calories
Decreases by 180 calories each day; after d days ;
S(d) = 3380 - 180d
Pattern continues until they both consume same number of calories each day
S(d) = C(d)
1520 + 130d = 3380 - 180d
130d + 180d = 3380 - 1520
310d = 1860
d = 6
Number of calories they will be consuming them ;
Using : S(d) = 3380 - 180d
S(6) = 3380 - 180(6)
S = 3380 - 1080
S = 2300
They will be consuming 2300 calories by then.
