Answer: 0</h3>
Explanation:
The single digits are {0,1,2,3,4,5,6,7,8,9}
So naturally 0 is the first thing to test.
The number 270 is a multiple of 9 because 9*30 = 270. The digits of 270 add to 2+7+0 = 9 showing that it's a multiple of 9. Refer to the "divisibility by 9 rule".
The next possible value of y will be 9 units higher than y = 0, so we go for y = 9. Meaning that 279 is also a multiple of 9 (because 2+7+9 = 18 is a multiple of 9).
I don't entirely know what you mean by 'rate of change', but I'll assume that you mean slope.
0, -4 and 3, 2 are on the coordinate plane.
From 0, we go over three to reach 3.
From -4, we go up six to reach 2.
Since slope is in essence, rise/run, we have the following fraction:
6/3, which can be re-written as 2/1 or just 2.
Hope this helps!
Answer: 7.4
Step-by-step explanation:
3x + 13 = 19
3x = 6
x = 2
Now substitute value of 'x' in the second equation:
2(2) + 1.2(2) + 1
= 4 + 2.4 + 1
= 5 + 2.4
= 7.4
