Answer:

x = -2a/(y - 2).

Step-by-step explanation:

y= 2(x-a)/x

Cross multiply:

xy = 2(x - a)

xy = 2x - 2a

xy - 2x = -2a

x(y - 2) = -2a

x = -2a/(y - 2).

Answer:

y = 2(x-a)/x

xy = 2x-2a

xy-2x = -2a

x(y-2) = -2a

x = (-2a)/(y-2)

Graph the function by making a table of values which table is correct
Talja [164]

It is often more convenient to evaluate a polynomial when it is written is "Horner form."

... f(x) = (((10x -4)x -8)x +3)x -6

The graphs offered can be distinguished by their values of f(1) and f(2), so our table can be a short one.

... f(1) = (((10·1 -4)1 -8)1 +3)1 -6 = -5 . . . . . . . eliminates graph d

... f(2) = (((10·2 -4)2 -8)2 +3)2 -6 = 96 . . . . eliminates graphs a and c

The appropriate choice is b.

10 points please help and explain how ;) brainliest answer first person to get it right
OverLord2011 [107]

Answer:

Open dot at -1 and shaded to the right.

Step-by-step explanation:

First you have to solve the inequality are you get |y|>-1

Now you can plot the inequality by placing an open dot on -1 since the inequality is greater than.

Since the inequality is greater than, you also have to shade when all y values are greater than -1 so you would shade to the right.

What is the solution to –2(5y – 5) – 3y ≤ –7y + 22?
Gre4nikov [31]
-2(5y - 5) - 3y < = -7y + 22
-10y + 10 - 3y < = -7y + 22
-13y + 10 < = -7y + 22
-13y + 7y < = 22 - 10
-6y < = 12
y > = -12/6
y > = -2....answer B
