3/4 I think is the answer not sure sorry if it's wrong
Let's check the answer
Start with equation (1). Plug in (x,y) = (-10,-1)
x + 5y = -15
-10 + 5y = -15 ... replace x with -10
-10 + 5(-1) = -15 ... replace y with -1
-10 - 5 = -15
-15 = -15 ... true equation
So we've confirmed one equation so far. Let's check the other equation
--------------------
Start with equation (2). Plug in (x,y) = (-10,-1)
y = (1/5)*x + 1
y = (1/5)*(-10) + 1 ... replace x with -10
-1 = (1/5)*(-10) + 1 ... replace y with -1
-1 = -2 + 1
-1 = -1
Since both equations are true when (x,y) = (-10,-1), this confirms the answer. Nice work on getting the correct answer.
Visually we can see the two lines crossing at (-10,-1). See the attached image. Note: 1/5 = 0.2 so the second equation can be written as y = 0.2x+1
Answer:
Yes, they do
Step-by-step explanation:
Yes, y = 3x represents direct variation. The fact that the line (graph) of y = 3x goes through the origin (0,0) reinforces this statement.
Multiplicative Identity Property
The product of any number and 1 is the number itself
To get the answer divide the diameter by two, so you can get the radius. So plug it into the formula A=π
8²=π
(8²)=64π
=200.96 and for multiplying pie I just used 3.14 instead the entire number so I could get it by having the decimal in the hundredths place.
