Solve the inequality: f(x)≤g(x). write the solution in interval notation.

1 answer:

3 0

The goal is to isolate x in both equations by adding, subtracting, multiplying or dividing both sides of the inequality by an identical value.

3x + 7 < 10
Subtract 7 to both sides
3x < 3
Divide both sides by 3
x<1

6x - 14 > 4
Add 14 to both sides
6x>18
Divide both sides by 6
x> 3

So x must be both lower than 1 OR bigger than 3. Solution (-∞;1)∪ (3;+∞) (corrected from a previous version)

Answer:

$278.2 \: ft$

Step-by-step explanation:

Descended feet:

$94 \: s \times 3.3 \: \frac{ft}{s} \: = 310.2 \: ft$

Ascended feet:

$32 \: s \times 1 \: \frac{ft}{s} = 32 \: ft$

Total elevation:

$(310.2 - 32) \: ft = 278.2 \: ft$

Answer:

6x³ - 8x + 9

Step-by-step explanation:

Step 1: Write out expression

2x + 7 + 6x³ - 1 + 3 - 6x - 4x

Step 2: Combine like terms (x)

6x³ - 8x + 7 - 1 + 3

Step 3: Combine like terms (constants)
