A line passes through the points (2, -4) and (4, 2). What is the equation of this line in slope-intercept form?
Aneli [31]

Answer:

A.

Step-by-step explanation:

Slope = y2-y1/x2-x1

(2,-4) = (x1,y1)

(4,2) = (x2,y2)

Slope = (2+4)/(4-2)

          = 6/2

          = 3

Y=mx+b   [Plugging (4,2) into this]

2 = 3×4 +b

2 = 12 + b

b = -10

Which function represents g(x), a reflection of f(x) = 6across the y-axis?
Otrada [13]

Answer: D.) g(x) = 6(3)^{-x}


Step-by-step explanation: We are given an exponential function f(x).

g(x) is an exponential function that is being reflected across y-axis.

According to rules of transformations y=f(-x).

That is variable x is being multiplied by a negative sign.

In the given options g(x) = 6(3)^{-x}, the variable x is being multiplied by a negative sign.

Therefore, correct option is D option.

Is the expression X space logical or space (Y space logical and space Z )equivalent to (X space logical or space Y )space logica
Anit [1.1K]

Answer:

To prove:

X+Y.Z=(X+Y).(X+Z)

Taking R.H.S

= (X+Y).(X+Z)

By distributive law

= X.X+X.Z+X.Y+Y.Z --- (1)

From Boolean algebra

X.X = X

X.Y+X.Z = X.(Y+Z)

Using these in (1)

=X+X(Y+Z)+Y.Z

=X(1+(Y+Z)+Y.Z --- (2)

As we know (1+X) = 1

Then (2) becomes

=X.1+Y.Z

=X+Y.Z

Which is equal to R.H.S

Hence proved,

X+Y.Z=(X+Y).(X+Z)
