5/4
(15/16)(4/3) The 4/3 is the reciprocal of 3/4
=5/4
1/3x+11.
1/3 of a number can be shown as 1/3x, since the number is not identified.
We can represent 11 more as +11.
This, our expression is 1/3x+11
Hope this helps!
Above, I changed the fraction form of x and y into exponential form so it is easier to see the differentiation. Now, we can differentiate:
Now that we have dy/dx, we can plug in the x, which is 4, and the y, which is 4/19. We know these values of x and y because your question stated y(4) = 4/19.
4/7 make into slope form which will get you that
Answer:
A=-2
B=-8
Step-by-step explanation:
In order for the system of linear equations to have infinitely many solution, they must be the same equation.
Ax-y=8
2x+y=B
We need to choose A and B so they are the same equation.
I notice they are both in the same form but in the second column you have opposites;
the -y and y.
So im going to multiply either equation by -1 so that part is exactly the same.
Don't choose both; choose only one.
Let's multiply the first equation by -1.
Doing this gives us the following:
-Ax+y=-8
2x+y=B
So now we can choose A and B so these equations appear exactly the same.
We need -A=2 and B=-8.
-A=2 implies A=(opposite of 2) which is -2.
Conclusion:
A=-2
B=-8
