Worth 50 points if you help<br> Plz it’s due in 3 hours it’s math and show ur work plz

Answer:

1 We set z=-4

(2*-4 + b)(-4 - 3) = 0

(-8 + b)(-7) = 0

Set the factor (-8 + b) equal to 0.

-8 + b = 0

Solving for b, we get 8

b = 8

2We simplify the equation to the form, which is simple to understand

6x-12=51-3x

We move all terms containing x to the left and all other terms to the right.

+6x+3x=+51+12

We simplify left and right side of the equation.

+9x=+63

We divide both sides of the equation by 9 to get x.

x=7

3 Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 6x = 35 + -8

Combine like terms: 8 + -8 = 0

0 + 6x = 35 + -8

6x = 35 + -8

Combine like terms: 35 + -8 = 27

6x = 27

Divide each side by '6'.

x = 4.5

Simplifying

x = 4.5

4 Combine like terms: 6x + x = 7x

14 + 7x = 70

Solving

14 + 7x = 70

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-14' to each side of the equation.

14 + -14 + 7x = 70 + -14

Combine like terms: 14 + -14 = 0

0 + 7x = 70 + -14

7x = 70 + -14

Combine like terms: 70 + -14 = 56

7x = 56

Divide each side by '7'.

x = 8

Simplifying

x = 8

5 15-4=11+3=14

19-14= x=5

6Combine like terms: -2 + 10 = 8

8 + 6x + 8x = 8

Combine like terms: 6x + 8x = 14x

8 + 14x = 8

Add '-8' to each side of the equation.

8 + -8 + 14x = 8 + -8

Combine like terms: 8 + -8 = 0

0 + 14x = 8 + -8

14x = 8 + -8

Combine like terms: 8 + -8 = 0

14x = 0

Solving

14x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '14'.

x = 0

Simplifying

x = 0

7idk sorry

8Solving

0.8 + 0.4x = 2

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-0.8' to each side of the equation.

0.8 + -0.8 + 0.4x = 2 + -0.8

Combine like terms: 0.8 + -0.8 = 0.0

0.0 + 0.4x = 2 + -0.8

0.4x = 2 + -0.8

Combine like terms: 2 + -0.8 = 1.2

0.4x = 1.2

Divide each side by '0.4'.

x = 3

Simplifying

x = 3

Step-by-step explanation:

i hope this is right good luck

4x+y=8 and x+3y=8 graphed

IRISSAK [1]

$standard \ linear \ equation\ :\\\\y=ax+b\\\\ \begin{cases} 4x+y=8\ \ |\ subtract\ 4x\ to\ both\ sides\\ x+3y=8 \ \ |\ subtract\ x\ to\ both\ sides \end{cases}\\\\\begin{cases} y=-4x+8 \\ 3y=-x+8\ \ | \ divide \ each \ term \ by \ 3 \end{cases}$

$\begin{cases} y=-4x+8 \\ y=-\frac{1}{3}x+\frac{8}{3} \end{cases}\\\\y=-4x+8\\ To \ find \ the \ x-axis \ intersection \ point, \\set \ y \ equal \ to \ zero \ and \ solve \ for \ x : \\ \\y=0 \ \to 0=-4x+8\\\\4x=8 \ \ | \ divide \ both \ sides\ by\ 4 \\\\x=2\\\\ point : \ \ (2,0)$

$To \ find \ the \ y-axis \ intersection \ point, \\set \ x \ equal \ to \ zero \ and \ solve \ for \ y : \\ \\x=0 \ \to y=-4 \cdot 0+8\\ y=8 \\ point: \ \ (0,8)$

$y=-\frac{1}{3}x+\frac{8}{3}\\\\ \ the \ x-axis \ intersection \ point \\ \\y=0 \ \to 0=-\frac{1}{3}x+\frac{8}{3}\\ \frac{1}{3}x=\frac{8}{3} \ \ | \ multiply\ both\ sides\ by\ 3 \\\\x=8 \\\\point: \ \ (8,0)$

$the \ y-axis \ intersection \ point \\ \\x=0 \ \to y=-\frac{1}{3} \cdot 0+\frac{8}{3} \\ y=\frac{8}{3} \\ point : \ \ (0,\frac{8}{3})$

$Answer :\\\\ \begin{cases} y=-4x+8 \ \ | \ multiply \ each \ term \ by \ (-3) \\ 3y=-x+8 \end{cases}\\\begin{cases} -3y=12x-24 \\ 3y=-x+8 \end{cases}\\+-------\\0=11x-16\\11x=16\ \ | \ divide \ both \ sides\ by\ 11\\x=\frac{16}{11}$

$y=-4 \cdot \frac{16}{11}+8 \\ y=- \frac{ 64}{11}+\frac{88}{11}\\y= \frac{24}{11}\\\\\begin{cases} x=\frac{16}{11} \\ y=\frac{24}{11} \end{cases}$
