The x^2 over the x is like subtracting x from x^2, so the new equation would be 9-x/-3. You divide 9 by -3 to get the final answer of -3-x, or -x-3, which is E.

PLEASE HELP, ILL GIVE BRAINLIEST!!
elixir [45]

Answer:

as mentioned above we have to solve it by cross multiplication.

Step-by-step explanation:

So,

4(3x-3)=5(2x-2)

12x-12=10x-10

12x-10x=-10+12

2x=2

X=2/2=1 Answer

Do 14 and 15 for 80 points :)
Savatey [412]

Answer:

14) t=2hours

15)a=5/4

Step-by-step explanation:

14) The graph of y = -0.5 l t l is an inverted "V-shaped" graph with highest point when t = 0 and y = 0.  

To obtain the graph of r = -0.5 l t - 1 l + 0.5, translate the graph of                           y = -0.5 l t l one unit to the right and 0.5 units upward.  The highest point on this graph occurs when t = 1 and r = 0.5.

Maximum rate of rainfall = 0.5 inches/hr

The rain stops when r = 0.  So,  -0.5 l t - 1 l + 0.5 = 0

                                                   l t - 1 l = 1

                                                    t - 1 = 1 or t - 1 = -1

                                                    t = 2 or t = 0

t > 0, so the rain stops when t = 2 hours

15)The vertex of the path of the ball is (6, 0), so the equation

has the form y = a⎜x − 6⎟ . Substitute the coordinates of

the point (5, __5

15)The vertex of the path of the ball is (6, 0), so the equation

has the form y = a⎜x − 6⎟ . Substitute the coordinates of

the point (5, __5

4) into the equation and solve for a.

y = a ⎜x - 6⎟

_5

4 = a ⎜5 - 6⎟

_5

4 = a ⎜-1⎟

_5

4 = a

An equation for the path of the ball is y =

_5

4

⎜x − 6⎟.

olga nikolaevna [1]

Answer:

x=2

sx = 2 - (2 x 0.04)

sx = 2 - 0.08

sx = 1.92

lx = 2 + (2 x 0.04)

lx = 2 + 0.08

lx = 2.08
