If I’m not mistaken I think this is what you’re asking for?
J. Would be your answer
It has a negative slope and the rise/run is -1/1, so the slope is -1x or -x
Answer:
C. 48
Step-by-step explanation:
first you solve 84 divided by 7 and your answer is 12 then you do 12x4 which is 48
For part a: you just need to find how far the vertex has been moved from the origin, or the point (0,0). As the vertex is at the point (2,-3), it has been translated right 2 horizontally and down 3 vertically.
For part b: you use the info found in part a to create the equation in the form of y=A(x-h)^2+k. In this case, A =1, so you can ignore it. The h value is the horizontal distance the vertex has been moved. Since it has been moved right 2, this part of the equation would be (x-2). I know it seems like it should be plus 2, but values in parentheses come out opposite. For the k value, find the vertical shift, which is down3, or -3.
Now that you have h and k, substitute them back into the equation.
Your final answer for part b is: y=(x-2)^2 -3.
Answer:
Step-by-step explanation:
Assume as a basis the final mixture is 1000 mL. That means 399 mL of alcohol
Let x = mL of Soln A and y = mL of soln B.
x = 2y.
Now x + y = 1000
and 0.2x + 0.17y = 399
but x = 2y so 0.4y + 0.17y = 399
0.57y = 399.
y = 700 mL (That is your mL of solution B)
