Answer:
8by + 2ax - 4bx - 4ay
Step-by-step explanation:
I assume you mean expand so:
(a - 2b)(3x - 5y) + (2b - a)(x - y)
3ax - 5ay - 6bx + 10by + 2bx - 2by - ax + ay
Now collect like terms:
2ax - 4ay - 4bx + 8by
This is your answer but in a better order:
8by + 2ax - 4bx - 4ay
Answer:
B) 59 cm²
Step-by-step explanation:
4x8=32
2x3=6
3x7=21
32+6+21=59 cm²
You will need to simplify the equation by:
2x - 8y = 32
put the x on the other side but negative.
-8y = -2x +32
ok so it will need to divide the negative 8 on y.
y = -2/-8x + 32/-8
simplify:
y = 1/4 + -4
So the slope is 1/4
The y intercept is -4
I think the question for this problem is to formulate an equation that could describe the behavior of the trend. To do this, let's see the trend first. In the first hour, the number of transactions is 10. In the 2nd hour, the transactions is 2(10) = 20. In the third hour, the transactions is 20(2) = 40. So, we can see that the trend is 10, 20, 40, 80, ....and so on. You notice that this is a geometric progression, where r=2. Thus, the equation for this will be:
Number of transactions = 10(r)ⁿ⁻¹ = <em>10(2ⁿ⁻¹), where n is the number of hours</em>
Many people view it as something dangerous/ not good for people
