A square has an area of 64 square feet. What is the length of each side of the square?

Correct me if I'm wrong but my answer is:

$\sqrt{64} = 8$

Step-by-step explanation:

No you are correct. That's the correct end result. Technically you should start with

Area = s^2

Area = 64 ft^2

s^2 = 64

sqrt(s^2) = sqrt(64)

s = 8

s = - 8 has no meaning.

Your way is fine.

$\textbf{answer: }$

$\textrm{the slope of the line segment pq is }\frac{1}{2}$

$\textbf{step-by-step explanation: }$

$\textrm{formula to find slope: }\\ \frac{y2 - y1}{x2-x1}$

$\frac{4 - 1}{)}$

$4 - 1 = 3\\ ) = 6\\ \frac{3}{6} = \frac{1}{2}$

$\textrm{m =}\frac{1}{2}$

What is the slope of the line segment pq?

Answer from: Quest

a. we have two

lines: y = 4-x and

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b. 4-x = 8-x^-1

x 4-x 8-x^-1

-3 7

8.33

-2 6 8.5

-1 5 9

0 4

1 3

2 2

7.5

3 1 7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:

x=-4.236

y = 4-x = 4 – (-4.236)

= 8.236

y = 8-x^-1 = .236)^-1

= 8.236

x=0.236

y = 4-x = 4 – (0.236) = 3.764

y = 8-x^-1 = 8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c. to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x and y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines. the

solution is, as stated, the point where the two lines cross on the graph.
