Answer:

f(-1)=7

Step-by-step explanation:

I am going to assume your question meant the equation

f(x)=2x^{2} -4x+1

So f(-1) can be found by substituting all the x terms in the equation with -1

f(-1)=2(-1)^{2} -4(-1)+1

And simplifying for our answer

f(-1)=2(1)+4+1

f(-1) = 2+4+1

f(-1)=7

Calculate the midpoint between (2,-5) and (4, -7).
balandron [24]

The midpoint between (2,-5) and (4, -7)  is Option D.(3-6)

Step-by-step explanation:

Given:

Points (2,-5) and (4, -7)

To Find:

Midpoint of the points=?

Solution:

The midpoint that lies between the two points is given by

(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Where

(x_m, y_m)= coordinates of the midpoint

(x_1, y_1)= coordinates of the first point

(x_2, y_2)= coordinates of the second point

we have,

x_1= 2

y_1= -5

x_2= 4

y_2= -5

Substituting the values in the mid point formula,

(x,y)=(\frac{(2+4)}{2},\frac{(-5-7)}{2})

(x,y)=(\frac{(6)}{2},\frac{(-12)}{2})

(x,y)=(3,-6)

If n is used as the initial amount of liquid in both A and B:

4(n-120) = n+120
4n-480 = n+120
3n = 600
n = 200

Each container originally held 200ml. Container A now has 80ml and Container B has 320ml
