Select the correct answer from each drop-down men. A jewelry artisan has determined that her revenue, y, each day at a craft fair is at most -0.5x2 + 302, where x represents the number
of necklaces she sells during the day. To make a profit, her revenue must be greater than her costs, 2.1 + 150.
Write a system of inequalities to represent the values of x and y where the artisan makes a profit. Then complete the statements.
of this system.
The point (30,230) is
The point (10,300) is
of this system

the answer is c. 23/3

step-by-step explanation:

compare

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
