Answer:
7
Step-by-step explanation:
I assume that 3,14 is 3.14
=3.14 x (200-175)2 - 150
=3.14 x (25)2 - 150
=3.14 x 50 - 150
=157-150
=7
Answer:
y = 5
slope = 0
Step-by-step explanation:
Answer:
I think it's the first one... but I'm not pretty sure.
Using the cross product property on this proportion gives us the following equation:
20 (2x - 9) = 10 (9)
Use the distributive property and multiply
40x - 180 = 90
Add 180 to both sides
40x = 270
Divide 40 from both sides
x = 270/40
Simplify fraction
x = 27/4
This should be your answer. Let me know if you need any clarifications, thanks!
Answer:
y=mx+b
y=-4/5x+5b
Step-by-step explanation:
(0,-5)
(-5,-1)
-1+5 is 4
-5-0 is -5
-4/5 is the slope
use one of the points and substitute x to find the y intercept, which gives you the full equation, which is y=-4/5x+5
