The next 3 terms would be: -14, -17, and -20 (the pattern is your -3 each time) the 100th term would be -279 i think because there is 93 spots left after the first 7 terms, so 93 x -3 = -279

| -6x - 3 | > 15

This expression can be written as:

a) -6x - 3 > 15 
b) -15 > - 6x - 3

Solving a part:

- 6x - 3 \ \textgreater \  15 \\  \\ 
- 6x \ \textgreater \  18 \\  \\ 
x \ \textless \  -3

Solving b part:

-15 \ \textgreater \  - 6x - 3 \\  \\ 
-12 \ \textgreater \  - 6x \\  \\ 
2 \ \textless \  x

or we can write:
x > 2

So the solution to given inequality is:
x \ \textless \  -3  \\ or  \\ x \ \textgreater \  2

The second option correctly lists this solution.

Drag a symbol to the first box and a number to the second box to complete the solution to this inequality. Each number or symbol
Over [174]

Answer:

z

Step-by-step explanation:

Given the inequality: -2(z + 5) + 20 > 6

Step 1: Distribute the bracket

-2(z + 5) + 20 > 6\\-2z-10+20>6\\-2z+10>6

Step 2: Subtract 10 from both sides

-2z+10-10>6-10\\-2z>-4

Step 3: Divide both sides by -2

Note that when you divide an inequality by a negative sign, the inequality sign is reversed.

-2z>-4\\\dfrac{-2z}{-2}< \dfrac{-4}{-2}\\\\$Therefore, $z

A rubber ball bounces after it is dropped from a height of 212 feet, and it
Tema [17]

Answer:

C. 8 bounces

Step-by-step explanation:

To solve this, you can write an equation before turning it into an inequality:

y = 212*(1/2^x)

(x is bounces, y is height)

Now you can change it into an inequality to fit the height of less than 1:

1 > 212*(1/2^x)

In order for the right side of the equation to be less than 1, 2^x must be greater than 212 (because 212*(1/212) is 1, so if the denominator is greater, it'll be less than 1). 2^8 is 256, which is greater than 212, so that means x is 8.

Because x represents bounces, that means the ball's height will be under 1 foot after 8 bounces.
