What is the solution to the inequality 7&lt;=-3x-4
kipiarov [429]

Answer:

The nearest option is -3 (negative 3)

So, Option B is correct.

Step-by-step explanation:

We need to solve the inequality 7 \leq  -3x-4

Solving:

Step 1: Switching sides of inequality and reversing the inequality

-3x-4\geq 7

Step 2: Adding 4 on both sides

-3x-4+4\geq 7+4\\-3x\geq 11

Step 3: Dividing both sides by -3 and reversing the inequality

\frac{-3x}{-3}\leq \frac{11}{-3}  \\x\leq -3.6\\

The nearest option is -3 (negative 3)

So, Option B is correct.

The quadratic function d= -4x+1,100 models a snowboarder's distance, in feet, from the bottom of a hill x seconds after the snow
Fynjy0 [20]

Answer:

16 seconds (Approximately)

Step-by-step explanation:

Given:

The function that gives the distance of snowboarder from the bottom of hill with time 'x' is:

d=-4x^2+1100

Final position of the snowboarder is d=100\ ft

Now, plugging in 100 for 'd' and solving for 'x', we get:

100=-4x^2+1100

Adding -1100 both sides, we get:

100-1100=-4x^2+1100-1100\\-1000=-4x^2

Dividing both sides by -4, we get:

\frac{4x^2}{4}=\frac{1000}{4}\\x^2=250

Taking square root and neglecting the negative root as time can't be negative. So,

\sqrt{x^2}=\sqrt{250}\\x=5\sqrt{10}=15.8\ s\approx 16\ s

Therefore, after 16 seconds, the snowboarder will be at a distance of 100 ft from bottom of hill.
