Letter A is the answer because
4y = 15 - 3x
so y = 15/4 -3x/4
I would start by plugging in a number for x. Just any random number. Let's take 2 for example. Then the equation would go from 2x + y = -4, to 2(2) + y = -4. Then solve.
2(2) + y = -4
4 + y = -4, after you've done that, plug in a number for y, that completes the equation. In this case, the only acceptable number, would be -8. Because it completes the number sentence.
4 + (-8) = -4
-4 = -4.
Now plug in other numbers, to get the same outcome. Hope this helped!

16/10=1.6 so the smallest number of combos would be 1.

the range is the spread of your data from the lowest to the highest value in the distribution
Answer:
x = 3.162
Step-by-step explanation:
Your first step is to get x by itself by subtracting 3 from both sides.
3-
= -7
- = -10
Now multiply by both sidex by -1 to make x positive.
= 10
now take the square root of both sides.
= 
x =
x = 3.162
