rate of change as in the gradient??
if yes then the formula would be rise over run, so y over x, therefore 1/3
Step-by-step explanation:
4x + 2y = 10 --------(1)
2x + 3y = 33 -----------(2)
Multiply 2 with eq. (1) and 4 with eq. (2)
8x + 4y = 20 ____________(3)
8x + 12y = 132 ______(4)
Subtracting (3) from (4),
8x + 4y = 20
- 8x -12y = -132
----------------------
0 -8y = -112
y = 112/8
y = 4 is the answer.
Putting the vakue of y in eq. (2),
2x + 12 = 33
2x = 33-12
2x = 21
x = 21/2 is the answer.

Step-by-step explanation:
Answer:
1024 outcomes
Step-by-step explanation:
Within a particular single question, we can select only 1 correct answer from 2 options. The number of ways of doing this is 2C1 and this is 2
This means for each question, there are only 2 possible outcomes. Now for 10 questions, the total number of possible outcomes would be the outcome of each of the questions multiplied by one another.
That would be (2)^10 which is 1024 outcomes
Its 5.9 cus you have the perimeter to 68 and the with 8.9 so its 5.9
