Answer:

50 A and 50 B

Step-by-step explanation:

A》20

B》10

A + B》100 (for pants)

A + 3B》200 (for shirts)

A = 20

A + 3B = 200

3B = 180

B = 60

(20,60)

B = 10

A + B = 100

A = 90

(90,10)

A + B = 100

A = 100 - B

A + 3B = 200

100 - B + 3B = 200

2B = 100

B = 50

A = 100 - 50 = 50

(50,50)

Revenue:

30A + 50B

(20,10): 30(20) + 50(20)

= 1,100

(20, 60): 30(20) + 50(60)

= 3,600

(90,10): 30(90) + 50(10)

= 3,200

(50,50): 30(50) + 50(50)

= 4,000

The x-coordinate of the vertex of the equation y = 2x2 − 4x + 12 The x-coordinate of the vertex of the equation y = 4x2 + 8x + 3

dolphi86 [110]

So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is $x=\frac{-b}{2a}$ , with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:

y = 2x^2 − 4x + 12: $x=\frac{4}{2*2}=\frac{4}{4}=1$

y = 4x^2 + 8x + 3: $x=\frac{-8}{2*4}=\frac{-8}{8}=-1$

In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.

Answer:

A=32

B=3

C=7

Step-by-step explanation:

Caitlyn surveyed 100 students to find out their favorite class. There were 29 students who enjoyed biology and 35 students who enjoyed English. There were 12 students who did not enjoy Biology, English, or Math.

29 like Biology so to find B you subtract. 29-6-5=3

35 like English so to find C 35-3-5-20=7

Total of 100 students subtract what you know to find A.

100-15-6-5-3-7-20-12=32
