Answer:
-8
Step-by-step explanation:
If 3x-4y=2, then for any number a we also have a(3x-4y)=a(2) by multiplication property of equality.
Therefore, for a=-4 we have -4(3x-4y)=-4(2) which means the value of -4(3x-4y) is -8.

Step-by-step explanation:
Heart rate will be represented by 
, minutes will be represented by 
.
Here's the equation I came up with:
We can also rearrange it to look like a point-slope equation. Either way works, it's the same equation.
This works because her heart rate is decreasing by a constant value. The initial heart rate is like the y-intercept, while the amount that it decreases by is the slope.
I hope this helps!
Answer: number 3 is 32 number 4 is 40 minutes
Step-by-step explanation:You see in number 3 it says a millipede has 14 more legs than a caterpillar. Also it states the total of the legs are 46. This means you must subtract. 46-14 is equal to 32. And for number 4 it states the total time of all her classes are 1 hour and 10 minutes. The yoga class is 30 minutes longer. This means you must subtract those 30 minutes from the 1 hour and 10 minutes. 1 hour and 10 minutes- 30 minutes is equal to 40 minutes. This is the answer.
Hope this helps!!
