Jamal throws a bean bag into the air. This graph shows the height of the bean bag, h, in feet after t seconds.

The graph shows a parabola which opens downwards. The horizontal axis is labeled t and ranges from zero to two. The vertical axis is labeled h and ranges from zero to fourteen. The curve begins at zero, midway between four and six, then moves upwards until a point midway between zero point five and one, fourteen, then moves downwards until stopping at the t-axis at a point between one point five and two, zero.

What is the meaning of the t-intercept?


The bean bag is released when t equals zero.


The bean bag is thrown from a height of 5 feet.


The bean bag hits the ground after 1.7 seconds.


The bean bag has a speed of 1.7 feet per second when it lands.

SOLUTION

my

Answers

Answer:

5x + 3y = 95

8x + 6y = 170

x = 10 ; y = 15

Step-by-step explanation:

Let :

x = pack of juice boxes

y = pack of water bottles

Pack of juice box = $5

Pack of water bottles = $3

Amount of money spent :

5x + 3y = $95

Number of drinks purchased :

8x + 6y = 170

Using both equations ;

5x + 3y = 95 - - - (1)

8x + 6y = 170 - - - (2)

Multiply (1) by 6 and (2) by 3

30x + 18y = 570

24x + 18y = 510

Subtract :

6x = 60

x = 60 / 6

x = 10

Put x = 10 in (1)

5(10) + 3y = 95

50 + 3y = 95

3y = 95 - 50

3y = 45

y = 45 / 3

y = 15

x = 10 ; y = 15
