7 + (-2)
2 plus -7 would equal -5, and so would -7 plus 2. Also, 7 plus 2 is nine; leaving us with the only possible choice... 7 + (-2).

What are three collinear points on line l?
Jet001 [13]

Points A, F, and G are three collinear points on line l.

\boxed{ \ The \ Answer \ is \ B \ }

<h3>Further explanation  </h3>

Let us consider the definition of collinear.  

Collinear  

Collinear points represent points that lie on a straight line. Any two points are always collinear because we can constantly connect them with a straight line. A collinear relationship can occur from three points or more, but they don’t have to be.  

Noncollinear  

Noncollinear points represent the points that do not lie in a similar straight line.  

Given that lines k, l, and m with points A, B, C, D, F, and G. The logical conclusions that can be taken correctly based on the attached picture are as follows:  

  • At line k, points A and B are collinear.  
  • At line l, points A, F, and G are collinear.  
  • At line m, points B and F are collinear.  
  • Point A is placed at line k and line l.
  • Point B is placed at line k and line m.
  • Point F is located at line l and line m.
  • Points C and D are not located on any line.

Hence, the specific answer to this key question is undoubted, i.e., points A, F, and G.  

<u>Note:</u>

All points can, also, be said to be coplanar. This is because the three lines intersect with each other and lie on a planar surface.

Coplanar  

Coplanar points represent a group of points that lie on the same plane, i.e. a planar surface that extends without end in all directions. Any two or three points are always coplanar, but four or more points might or might not be coplanar.

How to solve k(a)=4a + 2: find k(a-3)
uysha [10]

If you meant to say k=(-3)

First thing you would do is plug in the (-3) to a

Your equations would look like this:

k(a) = 4(-3) + 2

You would multiply 4 × -3, giving you -12.

k(a) = 12 + 2

Then you would add 12 + 2, giving you 14.

k(a) = 14

k(a) would equal 14.

A machine shop is manufacturing a pair of gears that need to be in a ratio as close to 1.1839323 as possible, but they can’t mak
Afina-wow [57]

Answer: Driven gear will have 50 teeth, and driver gear will have 42 teeth

Step-by-step explanation: First we have to know the formula of gear ratio which is started below

(No of teeth on driven)/(No of teeth on driver)

Note: we should all know in the combination of a gear system, we have two gears, the driver gear and the driven gear

So since the least amount of teeth for any gear is 50, we assume the no of teeth on the driven is 50

And no of teeth on the driver is x

50/x = 1.1839323

Cross multiply

x x 1.1839323 = 50

x = 50/1.1839323

x = 42.23

To the nearest whole number = 42

So therefore, number of teeth on the driver gear is 42

PLEASE HELP!!! Find the area of each figure to the nearest tenth. Show your work
Anettt [7]
I cannot make out the height along the left side.  However this problem is quite simple, let s= that measurement along the left side vertical line.  The area of this figure is just the area of a rectangle added to the area of a triangle...

A=(110*s)+(180-110)(s-50)/2

A=110s+35s-3500

A=(145s-3500) cm^2

...

The second problem is just a triangle:

A=4*6/2

A=12 cm^2
