Answer:
b)When they are on the same side of the Sun, the distance between Mars and Earth is approximately 8 times 10 Superscript 7 kilometers. and c)When they are on opposites sides of the Sun, the distance between Mars and Earth is approximately 3.8 times 10 Superscript 8 kilometers.
Step-by-step explanation:

Slope intercept form is y = mx + b
so make the equation look like that.
-9x + 10y = -9 ... add 9x on both sides
10y = -9 + 9x
10y = 9x - 9
<span>
y = (9/10)x - (9/10)

Answer:

Step-by-step explanation:
step 1
Find the value of x
we know that
r is the midpoint of qs
so
QR=RS
QS=QR+RS------> QS=2RS -----> equation A
RT=RS+ST ----> equation B
see the attached figure to better understand the problem
Substitute the given values in the equation B and solve for x





step 2
Find the value of RS

substitute the value of x


step 3
Find the value of QS
Remember equation A
QS=2RS
so
