Answer:
D. y = -1/3x
Step-by-step explanation:
The line through the origin means the equation will be a proportion of the form y = kx. (You can also see this by looking at the answer choices.) The value of k is ...
k = y/x . . . . . divide the above equation by x
For the given point (x, y) = (-3, 1), the value of k can be seen to be ...
k = 1/-3 = -1/3
Then the equation for the line is ...
y = -1/3x . . . . matches D
Answer:
36 because the absolute value of -9-3 is 12, and then 12 times 3 is 36
Answer:
226.08
Step-by-step explanation:
Atop = (3.14)(4)²
= 50.24
Abottom = Atop = 50.24
Aside = C x H
C = 2πr
= 2(3.14)(4)
= 25.12
25.12 * 5
= 125.6
125.6 + 50.24 + 50.24
= 226.08
5x+3(x-2)=90
5x+3x-6=90
8x-6=90
+6 +6
8x=96
\8 \8
X=12
