Answer:
The second one, question 4, would be C, y = -2x + 16
Step-by-step explanation:
You're trying to make an equation out of the information on the graph.
So, start with the format y = mx + b.
The variable m represents the slope. Use rise/run. I chose to use the points (0, 16) and (2, 12).
You would end up with a rise over run that looks like this: 4/2. Simplified, the slope would be 2. Because this line is moving downwards, your slope is negative.
So far, you have y = -2x + b.
The variable b represents the initial value, or where the line first touches the y-axis. You can see that the initial value is 16.
Plug that in. y = -2x + 16.
Hope this helps! Sorry I couldn't answer both, good luck on that test! <3
Answer:
Step-by-step explanation:
Well this is pretty simple
for the area we need to use the formula A=3.14*radius*radius
so we just plug it in and we get 3.14*8*8 which is 200.96 centimeters squared
for circumference we need to do C=3.14*diameter
to find the diamter we need to do 8 (radius) x 2 which is 16
plugging it in that would be 3.14 * 16 which is 50.24
So in this case the the area is 200.96 and the circumference is 50.24 :)
Good evening ,
Answer:
(C) 36
Step-by-step explanation:
The length of the continuous solid path from P To Q = 3×(Length of the dashed line) = 3×(12) = 36 in.

Answer:
-12
Step-by-step explanation:
2(6a-2b)-8(-2)
=2[6(-1)-2(4)]+16
=2[-6-8]+16
=2[-14]+16
=-28+16
=-12
