Solve the equations. Show the solution sets on a number line. Check your answers. c 9k+3 =−4

Naddika [18.5K]

Answer:

k = -7/9

Step-by-step explanation:

9k + 3 = -4

9k = -7

k = -7/9

On the number line just make a closed circle at -7/9. No line would be drawn, just the dot

-7/9 would be between 0 and -1, closer to -1

Solve using substitution x=(3y+1) and x+4y=15

natka813 [3]

The solution is: x= 7 and y = 2

Step-by-step explanation:

Given equations are:

$x = 3y+1\ \ \ \ Eqn\ 1\\x+4y = 15\ \ \ \ Eqn\ 2$

Putting x = 3y+1 in equation 2 from equation 1

$3y+1+4y = 15\\7y+1 = 15\\$

Subtracting 1 from both sides

$7y+1-1 = 15-1\\7y = 14$

Dividing both sides by 7

$\frac{7y}{7} =\frac{14}{7}\\y = 2$

Putting y=2 in equation 1

$x = 3(2) +1\\x = 6+1\\x = 7$

Hence,

The solution is: x= 7 and y = 2

Please help me<br> Expressions

11111nata11111 [884]

1a= (2x+5)+3x+15

1b= (2(4)+5)+3(4)+15=40

2a= (3x+5)•(4x-3)

2b= (3(2)+5)•(4(2)-3)=55

2c= 2(x) or 2(2)

How I got 2c is the perimeter of the rectangle LMNP subtract from (2(2)+9)+(2(2)+9)=26 which in return means you subtract 30 from 26 and get 4 which is 2(2) or 2x
