Answer:
First number = 4
Second number = 9
Step-by-step explanation:
If the first number = x, the second number = x + 5.
The calculation can be expressed as follows:
x + 2(x + 5) = 22
First, expand the bracket 2(x + 5):
x + 2x + 10 = 22
Combine like terms:
3x + 10 = 22
Subtract 10 from both sides:
3x = 12
Divide both sides by 3:
x = 4
First number = 4
Second number = 4 + 5 = 9
Answer:
The elements of S-block elements are 14, so therefore to create an inequality model we declare S to be the unknown variable.
therefore since we have 14 elements we use an inclusive class interval from 1-14. the model is given as
1≤S≥14
Step-by-step explanation:
you have to declare variables before for the unknowns.
you also declare the class interval to be inclusive class interval or exclusive class interval.
At x=2, y=4
At x=4, y=16
So the total change in y from x=2 to x=4 is 16-4=12
And since average rate of change = total change in y divided by total change in x within the same period, therefore the answer is 12/2 = 6
Hope that helps. Let me know if you have any questions.
I think the answer is b i've never learned this sorry :(
