Identify the slope (m) and y-intercept (b) of each linear equation.<br> 52. 3x+4y=24
nekit [7.7K]

Answer:

Step-by-step explanation:

  [1]    3x - 4y = -24

  [2]    -x - 16y = -52

Graphic Representation of the Equations :

   -4y + 3x = -24        -16y - x = -52  

 

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -16y + 52

// Plug this in for variable  x  in equation [1]

  [1]    3•(-16y+52) - 4y = -24

  [1]     - 52y = -180

// Solve equation [1] for the variable  y

  [1]    52y = 180

  [1]    y = 45/13

// By now we know this much :

   x = -16y+52

   y = 45/13

// Use the  y  value to solve for  x

   x = -16(45/13)+52 = -44/13

Solution :

{x,y} = {-44/13,45/13}

Solve these inequalities
Setler [38]

Answer:

x>±4

x<±1

Step-by-step explanation:

Given the inequalities

x² > 16

Square root both sides

√x² > ±√16

x > ±4

The solution is x>±4

2) x² < 1

Square root both sides

√x² <±√1

x < ±1

Hence the solution is x<±1

Evaluating Expressions<br>x-7<br><br> for x=-8 <br><br>for x=-11<br><br>for x= 16
kow [346]
You just substitute in what x equals. ex. x=16, x-7 : 16-7=9.

x-7

1. x= -8; -8-7= -15
2. x= -11; -11-7= -18
3. x=16; 16-7= 9
