WILL GIVE BRAINLIEST ANSWER!!!!Which of the following points satisfies the inequality 2x - 3y < 1?

(-2,1)
(1/2, 0)
(2, -1)

Answers

Answer 1
Answer: Check first one:
2(-2)- 3(1) < 1
-4 -3 < 1
-7 < 1
This is true, let's check others, just to be sure
Check second one:
2(1/2) - 3(0) < 1
1 - 0 < 1
This is false
Check third one :
2(2)- 3(1) < 1
4- 3 < 1
This is false

So answer is (-2,1)
Answer 2
Answer: (-2,1) satisfies
2×-2-3×1=-7
-7<1

whatn is x and y

Answers

5x + y = 2      ⇒ 10x + 5y = 4
2x + 3y = 62  ⇒ 10x + 15y = 310
                                   -10y = -306
                                    -10      -10
                                         y = -30.6
                            5x - 30.6 = 2
                                 +30.6  +30.6
                                      5x = 32.6
                                       5        5
                                        x = 6.52
                                   (x, y) = (6.52, -30.6)
ok sure!
first we have to find y

so...
lets start with the first one:

5x+y=2 (we cannot have two variables together so:
5x+y=2
   -y =-y  so.. now we have 5x= 2-y (but we must get y positive and by itself!) 
                                             -2    = -2
  so: now you have 
5x-2=-y but need a positive variable so multiply each side by a (-1) 
(-1) 5x-2=-y (-1) So..
-5x +2 =y so now we know Y!
therefore whenever you see why in the next problem insert in its place: -5x +2 
 
I hope it helps!! :) 

Nethan made 8 rose bouquets and 6 daffodil bouquets. Nethan only has enough flowers to make at most 20 rose or daffodil bouquets total. Let x represent the number of more rose bouquets and y represent the number of more daffodil bouquets that Nethan can make. Show the relationship between x and y graphically.

Answers

Answer:

Nethan made 8 rose bouquets and 6 daffodil bouquets.

Nethan only has enough flowers to make at most 20 rose or daffodil bouquets total.

Let x represents the number of more rose bouquets.

Let y represents the number of more daffodil bouquets.

The maximum bouquets that can be made = 20

And the number of bouquets made are = 14

So, additional bouquets are = 20-14=6

In equation form we can show like :

x +y= 6

or y=6 -x

or x=6- y

Putting values of x as 0,2,4 and 6 we get:

When x = 0 then y = 6  

When x = 2 then y = 4

When x = 4 then y = 2

When x = 6 then y = 0

You can see the graph attached.

Solve the equation: 7x = 42.
A. x = – 7
B. x = – 6
C. x = 6
D. x = 7

Answers

7x=42
Divide both sides by 7
42÷7 =6
6 x 7 = 42
C. x = 6
7x = 42

7x/7 = 42/7
x = 42/7
x = 6

Answer: x = 6

Which value, when placed in the box, would result in a system of equations with infinitely many solutions?y = 2x – 5

Answers

For a system of equations to have infinitely many solutions it must describe identical lines.
If you multiply the first equation by 2, then move the x term to the left side, you would get 2y-4x=-10
