Hi! To solve this just subtract 7 from both sides to get x = -4.
Hope this helped :)

<span>Subtract 7 from both sides of the equation. Check: Substitute -4 for x in the original equation. If, after the substitution, the left side equals the right side, your answer is correct. ( -4 ) + 7 = 3 </span>

For a given function ƒ(x) = x2 – x + 1, the operation –ƒ(x) = –(x2 – x + 1) will result in a
Mekhanik [1.2K]

Given:

The function is:

f(x)=x^2-x+1

To find:

The result of the operation -f(x)=-(x^2-x+1).

Solution:

If g(x)=-f(x), then the graph of f(x) is reflected across the x-axis to get the graph of g(x).

We have,

f(x)=x^2-x+1

The given operation is:

-f(x)=-(x^2-x+1)

So, it will result in a reflection across the x-axis.

Therefore, the correct option is A.

The price elasticity of demand of the pen will be -0.2.

<h3>How to compute the elasticity?</h3>

The demand and supply schedule will be:

Price Qd. Qs

$10. 250. 100

$20. 200. 90

$30. 180. 80

The price elasticity of demand from $1 to $2 will be:

= Percentage change in quantity demanded/percentage change in price

Percentage change in quantity demanded will be:

= (200 - 250)/250 × 100

= -20%

Percentage change in price will be:

= (20 - 10)/10 × 100

= 100%

Therefore, the elasticity of demand will be:

= -20/100

= - 0.2

The value gotten illustrates an inelastic demand.

In order to increase the total revenue, the price can be reduced as it will lead to more sales.
