Answer:

D.) x = 3

Step-by-step explanation:

4 + 3x = 2(3x - 7) + 9

4 + 3x = 6x - 14 + 9

3x - 6x = 9 - 14 - 4

-3x = -9

x = -(-9)/3

x = 9/3

x = 3

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}

Can someone plz answer B and C
Shkiper50 [21]

B. 
When two lines intersect they form two pairs of opposite angles.
Vertical angles are always congruent, which means that they are equal.
so  m<7 = m<8 or m<3y + 19 = m<5y-29


C. solve for y and measure <7 and <8

 3y + 19 = 5y-29
5y - 3y = 19+29
2y = 48
y = 24

so
5y-29 = 5(24) - 29 = 91
3y + 19 = 3(24) + 19 = 91

so <7 = 180 - 91 = 89
<7 = <8 = 89
