A linear function is a straight line that has a slope, and follows the formula: <em>
y = mx + b</em>

In which:
y = y
m = slope
x = x
b = y -intercept

A ball is thrown into the air from an apartment balcony and falls to the ground. The height of the ball, h metres, t seconds aft

andriy [413]

Answer:

$1+2\sqrt{2}$ seconds

Step-by-step explanation:

When the ball hits the ground, its height will obviously be 0. Therefore, you can set up the equation the following way:

$0=-5t^2+10t+35 \\\\-5(t^2-2t-7)=0$

Plugging this into the quadratic equation, you get:

$t=\dfrac{2\pm\sqrt{4+28}}{2}= \\\\\dfrac{2\pm4\sqrt{2}}{2}= \\\\1\pm2\sqrt{2}$

Since the time must be positive, it takes the ball $1+2\sqrt{2}$ seconds to hit the ground, or around 3.828. Hope this helps!

4x -5 = 2(2x +1)<br> I need help

Nostrana [21]

Answer:

No Solution

Step-by-step explanation:

$4x-5=2\left(2x+1\right)$

Expand:

$4x-5=2* \:2x+2* \:1$

$4x-5=4x+2$

Add 5 to both sides:

$4x-5+5=4x+2+5$

$4x=4x+7$

Subtract 4x from both sides:

$4x-4x=4x+7-4x$

$0=7$

No solution as this is false.
