Answer:

(Infinitely), (No solution), (One solution), (One solution)

Step-by-step explanation:

1. 5x + 9 = 9 + 5x (Infinitely)

2. -4x + 8 = -4x - 8 [minus -4x from both equation, we get 8 = -8, which is impossible] (No solution)

3. x - 3 = 3 - x [2x = 6, x = 3] (One solution)

4. 3x + 7 = 7x + 3 [4x = 4, x = 1] (One solution)

Absolute value of |x|-2=5
Stells [14]

Answer:

x = ± 7

|-7|-2=5

|7|-2=5

± means positive or negative

Step-by-step explanation:

|x|-2=5

Get x by itself by adding 2 to both sides.

x - 2 + 2= 5 + 2

-2 + 2 cancels out

x = 5 + 2

x = 7

Absolute value is how far a number is from 0.

x can be either positive or negative.

PLEASE I DESPERATELY NEED HELP WITHH THIS!!!!!!! I’ll give brainless and extra points!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Rina8888 [55]

Answer:

1. 4x + 6

2. -15x + 11

5. -x + 4

6. -4x + 7

9. 5x - 2

12. x + 16

Step-by-step explanation:

Remove the parenthesis for each one so everything's out in the open. Next, you group like terms. The numbers with variables on one side, and the other numbers on the other side. For example:

x + 3x - 2 + 8

Then, you combine like terms:

4x + 6

That's mostly how you do each one.

Chad casts a shadow that is 14.3 feet long. The straight-line distance from the top of Chad’s head to the end of the shadow crea
Elan Coil [88]
Imagine right triangle with first leg to be the Chad length and second leg to be the Chad's shadow. Second leg has length 14.3 ft and since t<span>he straight-line distance from the top of Chad’s head to the end of the shadow creates a 23° angle with the ground, you could consider the trigonmetric function
</span>
\tan 23^{\circ}= \dfrac{\text{Chad's length}}{\text{Chad's shadow length}},

then \tan 23^{\circ}= \dfrac{\text{Chad's length}}{14.3}, \\ \text{Chad's length}=14.3\cdot \tan 23^{\circ}=6.1.<span />
