X^2-4x+3=0 solutions <br>larger and smaller solutions

andrew11 [14]

Answer:

x = 3 or x = 1

Step-by-step explanation:

Solve for x over the real numbers:

x^2 - 4 x + 3 = 0

Subtract 3 from both sides:

x^2 - 4 x = -3

Add 4 to both sides:

x^2 - 4 x + 4 = 1

Write the left hand side as a square:

(x - 2)^2 = 1

Take the square root of both sides:

x - 2 = 1 or x - 2 = -1

Add 2 to both sides:

x = 3 or x - 2 = -1

Add 2 to both sides:

Answer: x = 3 or x = 1

The environmental science club is printing T-shirts for it's 15 members. The printing company charges a certain amount for each

alexandr402 [8]

Answer:

Step-by-step explanation:

Let $X$ be the cost of each shirt. From the information provided in the problem, we can setup the following equation:

$15X + 20 = 162.50$

Solving for $X$ will give us the answer:

$15X = 142.50$

$X = 9.5$

The height

andre [41]

The ball describes a parabola, as you can see in the attached picture. So, the point where the ball strike the ground is the point where the parabola meets the x axis. In fact, the x-axis is the set of points where y=0, which means that the ball has height 0 or -again- it hits the ground.

So, we have to set y=0 in our equation and look for the positive solution. We have

$-\dfrac{1}{14}x^2+6x+3=0 \iff x=42\pm\sqrt{1806}$

And the positive solution is

$42+\sqrt{1806}$

So that's the distance from the child where the ball strikes the ground.
