sandy hits a baseball that flies 114 meters through the air and into the stands.

if it takes the ball 4.1 seconds to travel that distance, what is its average speed?

a. 73 m/s

b. 16 m/s

c. 28 m/s

d. 5 m/s

The answer would be C.

Step-by-step explanation:

You would want to do 114/4.1

It equals 27.8

So to round up it would be 28 m/s

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
