It's even better if you have a telescope or binoculars. Both allow you to see planets, the moon, and stars even closer. Telescopes are more powerful than binoculars. With a telescope, you can see the moon close enough to see its features. Labeled images like this one can help you find different places on the moon or other objects in the night sky. Even without a telescope, you will still be able to find some of these place

What does this mean for you and your stargazing? Well, you may not make any major discoveries like Galileo did, but you can look up at the sky in your own backyard. You can see the moon and many of the same stars that early astronomers saw. You can even see planets. For example, this is an image of Venus, Mars, and the moon, as seen from Earth without a telescope or binoculars. It is amazing what you can find if you just look up!

What evidence does the author use to support the idea that a telescope is not needed to learn about Earth's moon?

A. Early astronomers saw many of the same starts without a telescope.
B. Looking up at the sky is enjoyable even if you don't have special tools.
C. You can see even more detail in the sky if you use a telescope.
D. You can see some of the features of the moon without a telescope.

step-by-step explanation:

so then what are you asking?

step-by-step explanation:

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        

7

  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.
