Arturiano [62]3 years ago
5 0
Converting to vertex form is one way of doing this
2x^2 + 12x + 19 
= 2(x^2 + 6x) + 19
= 2 [ x + 3)^2  - 9] + 19
=  2(x + 3)^2  - 18 + 19
= 2(x + 3)^2 + 1

the minimum value is 1

larisa86 [58]

Answer:

2/9

Step-by-step explanation:

28 marbles in all

"Half of the marbles are red."

28/2 = 14 red

"Half of the non-red marbles are white..."

14/2 = 7 white

"...and the rest are blue."

25 -14 -7 = 7 blue

"Todd chose a <u>white marble</u> at random... " -from the bag that has...

14 red 7 white 7 blue

"... and <u>kept it</u>."- so now the marbles left in the jar are...

14 red 6 white 7 blue

P (white) = Number of white marbles/ Total number of marbles = 6/27 = 2/9

Hanson is at a ball game with his family. he goes to the concession stand to buy soft pretzels and water bottles for everyone. a
guajiro [1.7K]

The system of equation that can be used to represent the situation is as follows:

  • x + y = 16
  • 2x + 3.5y = 47

The number of water bottle bought = 6

The number of pretzel bought = 10

Let

x = number of water bottle bought

y = number of pretzel bought

Hanson buys 16 items. Therefore,

  • x + y = 16

Hanson spends a total of $47. Therefore,

  • 2x + 3.5y = 47

<h3>Combined System of equation:</h3>
  • x + y = 16
  • 2x + 3.5y = 47

Therefore, let multiply equation(i) by 2

2x + 2y = 32

2x + 3.5y = 47

1.5y = 15

y = 15 / 1.5

y = 10

x + 10 = 16

x = 6
