Write the ictter of the correct answer in the box containing the exercise number. If the answer has a shade in the box
We can assign the value "2x" as the amount of money that Amelia which to achieve in twelve years.
So, his initial money is X.
We can try each percent to test if it could double the amount in 12 years.
x+0.06*12years*x=1.72X
x+0.12*12*x=1.44x
x+0.1*12*x=2.2x
x+0.166*12*x=2.992x
Therefore, the answer is 10 percent.
So to solve problems like these you can work out each equation by substituting the x and y with the coords from the vertex (2,-4) and which ever one is true is the corresponding equation.
Lets try the first one
A) y = 2( x-2)^2-4 this would become
-4 = 2(2-2)^2-4 we solve this and get
-4 = 2(0)-4
-4 = -4
so it seems like A is the correct answer, of course we'd wanna check out the other answers just to be sure.
Lets try one and do C
C) -2 = 2(-4-2)^2+2
-2 = 2(-8)^2+2
-2 = 130
These aren't equal so this can't be our equation
So you can also do one more just to be super sure you have the right answer but I think A is the correct one :)
87 1/2 is the answer. hope it help.
Answer:
y = -4/3x +4
Step-by-step explanation:
y= mx+b
solve for y.
4x+3y=12
Step 1: Add -4x to both sides.
4x+3y+−4x=12+−4x
3y=−4x+12
Step 2: Divide both sides by 3.
Let's solve for y.
4x+3y=12
Step 1: Add -4x to both sides.
4x+3y+−4x=12+−4x
3y=−4x+12
Step 2: Divide both sides by 3.
3y / 3 =-4x +12 /3
y = -4/3x +4
hopes this helps you out
