Pleas find x and y for the image above

(- 2, 11 ) and (- 1, 6 )

Step-by-step explanation:

Equate the right side of both, that is

x² - 2x + 3 = - 5x + 1 ( subtract - 5x + 1 from both sides )

x² + 3x + 2 = 0 ← in standard form

(x + 2)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x + 1 = 0 ⇒ x = - 1

Substitute these values into f(x) = - 5x + 1

f(- 2) = - 5(- 2) + 1 = 10 + 1 = 11 ⇒ (- 2, 11 )

f(- 1)= - 5(- 1) + 1 = 5 + 1 = 6 ⇒ (- 1, 6 )

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

you'll have to attache the image of the bar graph in order for us to answer : )
