Answer:

x<3

Step-by-step explanation:

2.40 + 2.20x < 9

move the constante to the right hand side and change its sign

2.2x<9-2.4

calculate: subtract the numbers 9-2.4

2.2x<6.6

Divide both sides of the inequality by 2.2

Find the slope of a line parallel to this given line

dybincka [34]

bearing in mind that parallel lines have the same exact slope, then any parallel line to the one above will have the same slope as that one.

$\bf \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \qquad \implies y = \stackrel{\stackrel{m}{\downarrow }}{-\cfrac{7}{3}}x-4$

5. A ball is thrown straight up leaving the player's hands at at 7.5 m/s. If air resistance is ignored, how high can the ball tr

aleksley [76]

The maximum height reached is 2.87 meters

<h3>What is maximum height?</h3>

The maximum height of an object is the highest vertical position along the trajectory of the object.

The given parameters are:

$u = 7.5ms^{-1}$ --- the initial velocity
$v = 0ms^{-1}$ --- the final velocity
$a =-g$ --- the acceleration

To calculate the height (s) of the ball, we make use of the following equation of motion:

$v^2 = u^2 + 2as$

Substitute known values

$0^2 = 7.5^2 - 2gs$

$0 = 56.25 - 2gs$

Collect like terms

$2gs = 56.25$

Substitute 9.8 for g

$2 \times 9.8 s = 56.25$

$19.6 s = 56.25$

Divide both sides by 19.6

$s = 2.87$

Hence, the maximum height reached is 2.87 meters
