Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 4x -
zepelin [54]

Answer:it has one and only one solution.

Step-by-step explanation:

The given system of equations is expressed as

4x - 5y = 24 - - - - - - - - - - - - -1

2x + 3y = -10 - - - - - - - - - - - - - 2

We would eliminate x by multiplying equation 1 by 1 and equation 2 by 2. It becomes

4x - 5y = 24

4x + 6y = - 20

Subtracting, it becomes

- 11y = 44

Dividing the left hand side and the right hand side of the equation by

- 11, it becomes

- 11y/- 11 = 44/- 11

y = - 4

Substituting y = - 4 into equation 2, it becomes

2x + 3 × - 4 = -10

2x - 12 = - 10

2x = - 10 + 12

2x = 2

Dividing the left hand side and the right hand side of the equation by

2, it becomes

2x/2 = 2/2

x = 1

Pls help u guys im litterally about kahshoot myself bc of school I just wanna cry
GarryVolchara [31]

Answer:

First blanks: 36 and 36

Second blanks: -7 or 7

Step-by-step explanation:

Simplify (x+6)^2 and you get x^2+12x+36. 36 is what’s missing in that blank, and it needs to be added to both sides. Next, the second set of blanks is what you get when you take the square root of both sides of the equation. Sqrt((x+6)^2)=x+6. Sqrt(49)= -7 or 7. So you have to put 7 and -7 in the second set of blanks.

Solve the system of inequalities: a) .4x−1≤0 <br> 2.3x≥4.6
OleMash [197]

Answer:

(a) x \leq 2.5

(b) x \geq 2

Step-by-step explanation:

Solving (a):

0.4x - 1 \leq 0

Add 1 to both sides

0.4x - 1 + 1\leq 0 + 1

0.4x \leq 1

Solve for x

x \leq 1/0.4

x \leq 2.5

Solving (b):

2.3x \geq 4.6

Solve for x

x \geq 4.6/2.3

x \geq 2
