Answer:

2x -y = 2

Step-by-step explanation:

If you want it in standard form this is what it would look like 2x-y=2

first, the easiest thing to do is multiply the whole thing by 3, since the fractions denominators are the same.

you should get:

2x -y = 2

standard form formula = Ax + By = C

so luckily, the equation above we just solved is already in standard form after multiplying everything by 3

remember that in standard form, A cannot be negative, and we can't have any fractions in the equation

Evaluate the expression when x=10, y=−2, and z=−5.
Vlad [161]

\frac{ -  {x}^{2} + 6z }{y}

if x=10 y=-2 and z=-5 then...

\frac{ { - 10}^{2}  + 6 \times  - 5}{ - 2}

we solve this to get...

<em>65</em>

therefore the answer to your question would be 65

hope this helped-have a good day bro cya)

If the Price Elasticity of Demand for a product is -.8, and the product currently sells for $100 per unit, how much will demand
egoroff_w [7]

Answer: Percentage change in quantity would decrease by 12.5%.

Step-by-step explanation:

Since we have given that

Price elasticity of demand = -0.8

Price of each unit = $100

After change, price of each unit becomes = $110

% change in quantity would be

\dfrac{New-old}{old}\times 100=\dfrac{110-100}{100}\times 100=10\%

As we know the relation between price, quantity and elasticity.

e_D=\dfrac{\text{\% change in quantity}}{\text{\%change in price}}\\\\-0.8=\dfrac{10\%}{x}\\\\x=\dfrac{10}{-0.8}\\\\x=-12.5\%

Hence, Percentage change in quantity would decrease by 12.5%.
