Determine the y-intercept of the following parabola:
y = 3x2 - 12x - 5

Answers

Answer 1

Answer:

-5

Step-by-step explanation:

Find the y-intercept by plugging in x = 0:

  y = 3x^2 - 12x - 5

  y = 3(0^2) - 12(0) - 5

  y = 0 - 0 - 5

  y = -5

(0, -5)

Evaluate [7] + | - 3|

Answers

Answer:

=[7]+|-3| solve for the absolute value {-3 ->3}

=7+3

=10

Answer:

10

Step-by-step explanation:

Whenever you see those numbers in those specific brackets, it's asking for the absolute value of that number.

The absolute value is the distance from 0.

So, if you see -3 in those brackets, it's 3 because both -3 and 3 are 3 spaces from 0.

So 7 + 3 = 10.

If 3 tickets to a certain show cost $13.20, what would 7 tickets cost?

What is this answer?

Answers

Answer:

$ 30.8

Step-by-step explanation:

ratio and proportion:

3 tickets  = 7 tickets

$13.20            x

then cross multiply:  3 (x) = 13.20 (7)

simplify: 3x = 92.4

solve for x = 92.4 / 3

x = $ 30.8

therefore,

7 tickets costs $ 30.8

Answers

Answer:

x = 133                                         x = -7

Step-by-step explanation:

| x/7 - 9| = 10

There are two solutions, one positive and one negative

x/7 - 9 = 10             x/7 - 9 = -10

Add to to each side

x/7 - 9+9 = 10+9             x/7 - 9+9 = -10+9

x/7 = 19                              x/7 = -1

Multiply each side by 7

x/7 *7 = 19 *7                             x/7*7 = -1*7

x = 133                                         x = -7
