Answer:

(0,2)

Step-by-step explanation:

Rule for a rotation of 180° about the origin: $(x,y)\rightarrow(-x,-y)$

We are given the point (0, -2).

Applying the rule:

$(0,-2)\rightarrow(0,2)$

A' should be at (0,2).

In the standard (x, y) coordinate plane which equation represents a line through the point (6, 1) and perpendicular to the line

Nata [24]

Answer:

d. -2/3x+5

Step-by-step explanation:

Because the line is perpendicular, the slope must be the inverse of the original slope. The inverse of 3/2 is -2/3. To find the b value, you plug (6,1) into the equation y=-2/3x+b

1=-2/3(6)+b

1=-4+b

5=b

The final equation is y=-2/3x+5

miss Akunina [59]

Answer: Option 'a' is correct.

Step-by-step explanation:

As we know that

Nominal wage is the value of wage in dollars that a particular person gets, whereas the real wage is the value of wage he is actually used that shows the purchasing power of a particular person.

If the wage is increased by 3%, and the inflation is increased by 6%.

Then, the nominal wage has increased but real wage decreased due to increase in inflation.

Hence, option 'a' is correct.
