Answer:

B.

Step-by-step explanation:

First, notice that we can cancel out an x in the second term. Thus:

\frac{3x^2}{x^2+x} =\frac{3x^2}{x(x+1)} =\frac{3x}{x+1}

As with the last question, change the sign to multiplication and "flip" the second term:

\frac{2x-1}{x+1}\cdot \frac{x+1}{3x}

Multiply straight across:

=\frac{(2x-1)(x+1)}{(x+1)(3x)}

Cancel the (x+1) term:

=\frac{2x-1}{3x}

Cannot be simplified further.

Someone please help​
dedylja [7]

Answer:

1. y = -2x + 5

2.  y = 3/5x + 5

3. y = -4/5x - 4

4. y = - 1

5. yes

6. yes

7. yes

8. no

Step-by-step explanation:

1.   (4,-3) parallel to y= -2x

     -3 = -2(4)+b

     b=5

2. (-5,2) parallel to y = 3/5x

    2= 3/5(-5)+b

     b=5

3. (-5,0) -4/5x

   0 = -4/5(-5)+b

    b = -4

4. (-4,-1)

    y= -1

5. yes

6. yes

7. yes

8. no

  • Same slope = parallel ex. y = -5x +7, y = -5x +12
  • opposite reciprocal  = perpendicular ex. y = -5x +7, y = 1/5x + 12
  • to find "b" with slope and point

          (x,y)  y = mx + b

          plug in the y value and x value in the eqaution and m=slope, solve for b

If DM=35, what is the value of r ?
balu736 [363]

Answer:

r=12.5 units

Step-by-step explanation:

Well assuming that DM means diameter of a circle, then r should be the radius of the circle.

Diameter of a circle is twice the radius of the circle, hence with the value of Diameter, you should half it to get the value of radius.

Given  diameter =25

Radius will be= 25/2 = 12.5 units

Using the Taylor rule, if inflation is 1 percent, desired inflation is 2 percent, and output is 2 percentage points below potent
antoniya [11.8K]

Answer:

1.5%

Step-by-step explanation:

According to the Taylor rule, the federal funds rate targeted by the Fed is:

FFR = 2+AI+0.5*(AI-DI)+0.5PD

Where AI is the actual inflation (1%), DI is the desired inflation (2%) and PD is the deviation from potential (2%):

FFR = 2+1+0.5*(1-2)+0.5*(-2)\\FFR=1.5\%

The Fed should target a federal funds rate of 1.5%.
