Answer:

The equation 4x -6y = 12 is in

"standard" form. if you modify it to be in the "slope intercept" (y=mx+b)

it will be modified to help more easily graph

y= 2/3 x -2 is the same equation in slope intercept (graphing) form...

here you can see that slope (rise over run) is positive and is 2/3 thus it goes from lower left to upper right... the "y-intercept" (the B) is at "-2" thus the line intercepts the y axis at -2

you can find the x and y intercepts by replacing the x with a 0 to get  the y intercept, and then replacing the y with a 0 to get the x intercept

9-8x=35 explain please
ANEK [815]

9 - 8x = 35

subtract 9 from both sides

-8x = 26

divide both sides by -8

x= -26/8

you can simplify this to -13/4

Anne’s marginal income tax rate is 32 percent. She purchases a corporate bond for $10,000 and the maturity, or face value, of th
Alex73 [517]

Answer:

Anne’s after-tax rate of return from the corporate bond is 3.5% or 5% x (1-.3). Because interest from the bond is taxed annually and her rate is assumed to be constant, the after-tax rate of return doesn’t depend on her investment horizon. Thus, her annual after-tax rate of return remains at 3.5% if the bond matures in ten years.

You can use any data set in this table (except the row with x) to get the ratio.

so 20/196 is the ratio which equals about .102041

then multiply that decimal by the weight in the x row to see what x is

so 1078(.102041) = 110.000198 just round that to 110. you can also verify that ratio by checking other data points. for instance

490(.102041) = 50.00009 or 50

so you know x is 50 so answer is either b or d

then you know the ratio .102041, so does (10/98) = .102041

or does (98/10) = .102041

if you do the division you will see that (10/98) = .102041

so the answer is D

Write an expression that represents the area of a circle with radius 3x^3. (For any circle with radius r, a=π r^2 = π .r .r ^.)
aalyn [17]

9514 1404 393

Answer:

  B. 9πx^6

Step-by-step explanation:

Putting the given radius into the area formula gives ...

  A = πr^2

  A = π(3x^3)^2 = π(3^2)(x^(3·2))

  A = 9πx^6
