Answer:

y=-\frac{4}{5}x +4

Step-by-step explanation:

Recall that slope-intercept form is the following form: y=mx+b, where m is the slope and b is the y-intercept.

To get an equation into slope-intercept form, we just need to solve for y.

We begin with the equation 4x+5y=20. With this, we can solve for y to get our answer.

4x+5y=20\\\\5y=-4x+20\\\\y=-\frac{4}{5}x +\frac{20}{5} \\\\y=-\frac{4}{5}x +4

Help!! Simplify (see photo) pls explain.
wolverine [178]

Answer:

The answer to your question is: 4x²y³

Step-by-step explanation:

Simplify                                     ∛(-64x⁶y⁹)

                                                 

First, find the prime factors of 64

      64   2

      32   2

      16    2

       8    2

       4    2

       2    2

        1              then 64 = 2⁶

                                            ∛ (-2⁶x⁶y⁹)

Roots can be expressed as fractional powers where the numerator is the power of the number inside the root and the denominator is the root.

Ex.        -2 ⁶/³       x⁶/³      y⁹/³

Now simplify

                       (-2)²  x²  y ³

Finally

                       4x²y³

PLEASE HELP !!!!!
Anastaziya [24]

Answer:

  -10%

Step-by-step explanation:

  price elasticity of demand = % change in demand / % change in price

Here, the "price" changes from 15 to 45, so its percent change is ...

  ((new value)/(old value) -1) × 100%

  = (45/15 -1) × 100%

  = 200%

The % change in demand is given as -20%, so the price elasticity is ...

  price elasticity of demand = (-20%)/(200%) = -0.10 = -10%
