Answer:

(-1,2)

Step-by-step explanation:

To find the solution, we need to substitute in the points into the equation

5x-2y = -9

(1,-3)

5(1) -2(-3) = -9

5 +6=-9

11 =-9

This is not true so this is not a solution


5x-2y = -9

(2,-4)

5(2) -2(-4) = -9

10 +8 = -9

18 =-9

This is not true so this is not a solution


5x-2y = -9

(-1,2)

5(-1) -2(2) = -9

-5 -4 = -9

-9=-9

This is true so this is a solution


5x-2y = -9

(-2,5)

5(-2) -2(5) = -9

-10-10 = -9

-20=-9

This is not true so this is not a solution

Answer:

4. C

5. 7

6. 3

Step-by-step explanation:

Four:

You have to multiply both of them. Just easy math!

Five:

This one is more complicated. You can see that it is asking you to plug in for a,

F(3):

f(3)= 4(3)-5

f(3)=12-5

f(3)=7

F(1.25):

f(1.25)=4(1.25)-5

f(1.25)=5-5f(1.25)=0

So now just subtract the answers. 7-0 equals 7.

Six:

Just look at the graph and see what number corresponds with y(6), or the 6 on the y axis. It appears to be three.

Have a nice day! Hope this helps. Don't forget to mark brainliest!

Crest = Highest point of the wave.

Trough = Lowest point of the wave.

Wavelength = Distance from one crest/trough to the next (m)

Wave Height = Height from trough to crest (m)

Wave steepness = ratio of wave height to wavelength.

Amplitude = distance from the centre of wave to the bottom of the trough (m)

1. How much work is done when a 65 newton force moves a block 5 meters?
Alik [6]

Answer:

i am not sure but i might know how to do it

Step-by-step explanation:

work is described as taking place when a force acts upon an object to cause a displacement. When a force acts to cause an object to be displaced, three quantities must be known in order to calculate the work. Those three quantities are force, displacement and the angle between the force and the displacement. The work is subsequently calculated as force•displacement•cosine(theta) where theta is the angle between the force and the displacement vectors. In this part of Lesson 1, the concepts and mathematics of work will be applied in order to analyze a variety of physical situations
