Find the x and y intercepts of the equation 8x+y=-9
Juliette [100K]

Answer:

see explanation

Step-by-step explanation:

To find the intercepts, that is where the graph crosses the x and y axes.

• Let x = 0, in the equation for y-intercept

• Let y = 0, in the equation for x-intercept

x = 0 : 0 + y = - 9 ⇒ y = - 9 ⇒ (0, - 9 ) ← y- intercept

y = 0 : 8x + 0 = - 9 ⇒ x = - \frac{9}{8} ⇒ ( - \frac{9}{8}, 0) ← x- intercept

The average height of a barometer during one week was 30.84 inches. for six week days of the same week the average height was 30
balandron [24]

The height of the barometer on Sunday = 34.8 inches

How is the barometer height on Sunday calculated?

Consider the barometer height for one week,

The average height of a barometer during one week = 30.84 inches

The total height of a barometer during one week = 30.84 * 7

                                                                                  = 215.88

Consider the barometer height for 6 weekdays,

The average height of a barometer for 6 weekdays of the same week= 30.18 inches

The total height of a barometer for 6 weekdays = 30.18 *6

                                                                                =181.08

The barometer height  on Sunday = One week height- 6 days height

                                                         =215.88 - 181.08

                                                         =34.8  inches

What is a height?

  • Height is the distance vertically between an object or figure's top and bottom.
  • Height is also referred to as altitude .
  • Average height is the sum of all the heights divided by the number of the given heights.
