Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{x =  \frac{2}{45} }}}}}

Step-by-step explanation:

\sf{ - 5 =  \frac{ - 2}{9x} }

Apply cross product property

\dashrightarrow{ \sf{ - 5 \times 9x =  - 2}}

\dashrightarrow{ \sf{ - 45x =  - 2}}

Divide both sides by -45

\dashrightarrow{ \sf{ \frac{ - 45x}{ - 45}  =  \frac{ - 2}{ - 45} }}

\dashrightarrow{ \sf{x =  \frac{2}{45} }}

Hope I helped!

Best regards! :D

Which of the following is a solution of 4x + 2y ≤ 6?
cestrela7 [59]

Answer:

D. (1,0)

Step-by-step explanation:

Just plug in each coordinate for x and y into 4x+2y and see which one is less than or equal to 6.

Lets go through all of the possible answers:

<u>A</u>. (0,4)

4(0) + 2(4) ≤ 6

0 + 8 ≤ 6

8 ≤ 6

This is false.  8 is not less than or equal to 6.

<u>B</u>. (5,0)

4(5) + 2(0) ≤ 6

20 + 0 ≤ 6

20 ≤  6

This is false.  20 is not less than or equal to 6.

<u>C</u>. (5,7)

4(5) + 2(7) ≤ 6

20 + 14 ≤ 6

34 ≤ 6

This is false because 35 is not less than or equal to 6

<u>D</u>. (1,0)

4(1) + 2(0) ≤ 6

4 + 0 ≤ 6

4  ≤ 6

This is true, because 4 is less than 6.

The ball's height( in meters above the ground), x seconds after Amir threw it, is modeled by : h(x)=-(x-2)^2 +16 what is the hei
Bess [88]

Answer:

20 m

Step-by-step explanation:

The height of the ball in metres is given as:

h(x) = (x-2)^2 + 16

where xis time, in seconds.

At the instant that the ball is thrown, the time is 0 seconds. This means that the height will be h(0):

h(0) = (0 - 2)^2 + 16\\\\\\h(0) = (-2)^2 + 16\\\\\\h(0) = 4 + 16\\\\\\h(0) = 20 m

The height of the ball is 20 metres.

GarryVolchara [31]

Answer:

Why? You have it there. Anyways, here's the step=by step.

Step-by-step explanation:

The equation for the volume of a cylinder is

V= π × height × radius²

or

V=π × r² × h

What you'll do then is multiply

11.1 × 34.4² × 3.14

Type that in a calculator and boom, you got your answer!
