Answer:
y=-8
Step-by-step explanation:
Remember PEMDAS (Parentheses/Exponents/Multiplication/Division/Adding/Subtracting)
Multiply 4 and -2= -8
-8-2y=8
Now do inverse operations
to get rid of the -8 you add it to the other side = -2y=16
Then to get rid of the -2 you divide it out to get the y by it self to get y=-8
Answer:
Step-by-step explanation:
Please see diagram attached.
Moon A and C are 100,000km + 10,000 = 110,000km from center of planet.
So they are 110,000 + 110,000 = 220,000km apart.
The circumference of a circle is 2•3.14(Pi)•R(radius) or 3.14(Pi)•D(diamater).
Since we have our diameter, 60, we need to multiply it by Pi.
60Pi is your answer.
I hope this helps!

Answer:
-10
Step-by-step explanation:
A slope's equation for 2 points on a coordinate plane is y² - y^1 ÷ x² - x^1
Note that the exponents aren't meaning powered, but just as a marking.
x1 is 2, x2 is 4, y1 is 150, y2 is 130
130-150 / 4-2 = -20/2, so -10
