If you would like to solve - 21 + (- 13) + (- 9), you can calculate this using the following steps:

- 21 + (- 13) + (- 9) = - 21 - 13 - 9 = - 43

The correct result would be A. - 43.

Write an inequality using variables x and y whose graph is described by the given information. The points (2,5) and (-3,-5) lie
luda_lava [24]

The inequality using variables x and y which satisfy the points are; y>-3x+3.

<h3>What is inequality?</h3>

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Given that the points (2,5) and (-3,-5) lie on the boundary line.

The system of inequality is given by:

y>-3x+3-

Now, the point that will lie in the solution set to the following system of inequality are the point that satisfies the inequality.

a)  (6, 5)

when x=6 and y= 5

then we have:

y>-3x+3

6 > -3×5 + 3

6>- 15+3

5 > -12

This means that the point will lie in the solution set.

Also, (-2, -3) when x= -2 and y= -3

then we have:

5 > -3×(-2) + 3

5> 6 + 3

5> 9

Hence, the inequality using variables x and y which satisfy the points are; y>-3x+3.

I WILL MARK BRAINLIST, HELP PLEASE
Rudik [331]

Answer:

 t = 204    

Step-by-step explanation:

Let t = initial number of trees

 

"remove 5 trees at the start of the season"  means

    (t    - 5)     remain

 

"each remaining tree made 210 oranges for a total of 41,790 oranges"    means

        ( t   - 5)           *        210                  = 41790

 

Now, you can solve for t:

       (t-5)(210) = 41790                     [just re-writing]

       210t - 1050 = 41790                    [distribute]

       210t = 42840                            [add 1050 to each side]

         t = 204                                  [divide each side by 210]

 

There were initially 204 trees.  After 5 were removed, the remaining 199 produced 210 oranges each for a total of 199*210 = 41790 oranges.

Tagged? 84 if the 10 weren’t thrown back in general? 94+20=114 I’m not sure if this answers your question, sorry if it doesn’t, your question wasn’t very specific.
