Yes... it can be a horizontal line
Answer:
(42,28)
Step-by-step explanation:
set up the problem by converting percentages to decimal
x+y=70
.30x+.80y=50(x+y)
solve for x, so minus y in order to get it x alone. equation should look like this: x=70-y
30(70-y)+80y=50(70-y+y)
solve the equation for y
y=28
plug the value of y into the equation x=70-y
x=70-28
solve for x
x=42
check the solution of (42,28)
42+28=70
30*42+80*28=50(42+28)
simplify the equations
70=70
3500=3500
the ordered pair is a solution
so James needs 42 liters of 30% antifreeze and 28 liters of 80% antifreeze.

The slope will be positive because -/-=+ and +/+=+
Answer:
I believe the answer would be 4
Step-by-step explanation:
I'm going to use (a) to represent the side length in my explanation. side length is equivalent to the square root of the surface area over 6. The 6 is coming from there being 6 faces on a cube. So to solve this equation, you would first write it out. a=96/6. Next you would divide 96/6, giving you 16. and then lastly, you would find the square root of 16, which is 4. giving you a final answer of 4.
Hope this helps, and you understand it more!
