Step-by-step explanation:
Let the required number be x.
According to the given information:

Hence the required number is 31.
Answer:
If these are addition:
1) 7
2) 3
3) 1
4) -3
5) 0
6) -5
If they are subtraction:
1) 9
2) 9
3) -7
4) 7
5) -4
6) 3
Step-by-step explanation:
Difference is subtraction, but your examples (7 and -3 = 10) implies that these are addition problems. Next time please set them up in a mathematical form.
This is how the problems would be set up:
Addition:
1) 8+(-1)= 7
2)6+(-3)= 3
3)-3+4= 1
4)2+(-5)= -3
4)-2+(-2)= 0
6)-1+(-4)= -5
Subtraction:
1) 8-(-1)= 9
2)6-(-3)= 9
3)-3-4=- 7
4)2-(-5)= 7
4)-2-(-2)= -4
6)-1-(-4)= 3
Answer:
D
Step-by-step explanation:
To check this answer, you could obviously graph the points, but without graphing, you can tell the line would be straight because each x value is multiplied by the same number to get the corresponding y value.
3 x 5 = 15, 4 x 5 = 20, etc. This shows linear growth. If each x value were multiplied by twice itself (3 x 6, 4 x 8, and so on), you wouldn't have a straight line because the number that x is multiplied by changes depending on the value of x.
B is the answer
just like the picture
( T' is not exact. it just shows the reflection)
Using it's concept, the range of the function is given as follows:
0 ≤ m ≤ 1200.
<h3>What is the range of a function?</h3>
The range of a function is the set that contains all possible output values for the function.
For this problem, we have to consider these two bullet points next, considering the mass is the output value of the function.
- The smallest possible mass for the substance is of 0 grams, as after the substance decays to 0 grams, it will not assume a negative value, it will just disappear.
- The greatest possible mass for the substance is the initial mass of 1200 grams, as the substance does not adquire mass with time, it just loses it.
Considering these masses, the range of the function is given as follows:
0 ≤ m ≤ 1200.
