1. Given the equation (x – 3)2 – 32 = 17 a)
m_a_m_a [10]
We know that

The square root property<span> is one method that is used to find the solutions to a quadratic equation.  This method involves taking the square roots of both sides of the equation.  
</span>(x – 3)² – 32 = 17-------> (x – 3)² = 17+32-----------> (x – 3)² = 49
(x – 3)² = 7²--------> <span>will take the square root of each side
</span>so
√(x – 3)²=(+-)√7²------> <span>notice the use of the </span> sign (+-), this will give us both a positive and<span>  a negative root
</span>
then

x-3=7--------> x=10
x-3=-7-------> x=-4

the answer Part a) is
x=10
x=-4

Part b) Explain why the given equation has two solutions.

the answer part b) is
Because exist<span> the possibility of two roots for every square root, one positive and one negative</span>

Chantal bicycles at a speed of 20 miles per hour and has already riden 45 miles when Trisha begins cycling. Trish bicycles at a
melomori [17]

Answer:

Chantal and Trisha will have both traveled 105 miles in 20 minutes.

Step-by-step explanation:

y is distance in miles, x is time in hours.

The two equations are:

y = \frac{20}{x} + 45

y = \frac{35}{x}

Set them equal to each other and solve for x:

\frac{35}{x} = \frac{20}{x} + 45

\frac{35}{x} - \frac{20}{x} = 45

\frac{35-20}{x} = 45

\frac{15}{x} = 45

x = \frac{15}{45} = \frac{1}{3} hours = 20 minutes

Plug that back into the equations to confirm this x gives the same y:

y = \frac{20}{1/3} + 45 = 105 miles

y = \frac{35}{1/3} = 105 miles
