Answer:
Step-by-step explanation:
y = -2x - 3
7x - 5y = -6
7x - 5(-2x - 3) = -6
7x + 10x + 15 = -6
17x = -21
x = -21/17
y = -2(-21/17) - 51/17
y = 42/17 - 51/17
y = -9/17
(-21/17, -9/17)
Answer: x=8.56365
Step-by-step explanation:
You have the angle and hypotenuse and have to find the opposite so you use sin.
Sin#=o/h
Sin35=o/20
Then I just put that into my calculator and got x= 8.56365. (I added the decimals cause idk what you need to round to)
First of all we have to find the slope
y₂-y₁
--------
x₂-x₁.
2 - (-2)
------------
0 - 7
4
---
-7
this is the slope
Answer:
47.1 inches
Step-by-step explanation:
As your hint says C=π*d
C= circumference which is what you are solving for
they said to use 3.14 for pi
d= diameter which is 15 inches
C= 3.14*15 = 47.1
