Answer: r=-2
Step-by-step explanation:
5r=(−3)(r)+(−3)(3)+−7
5r=−3r+−9+−7
5r=(−3r)+(−9+−7)
5r=−3r+−16
5r=−3r−16
5r+3r=−3r−16+3r
8r=−16
8r/8 = -16/8
r=-2
Answer:
The answer to your question is below
Step-by-step explanation:
-4x² + 9y² + 32x + 36y - 64 = 0
-4x² + 32x + 9y² + 36y = 64
-4(x² + 8x ) + 9(y² + 4x ) = 64 Factor coefficients
-4(x² + 8x + 4²) + 9(y² + 4x + 2²) = 64 - 64 + 36 Complete trinomials
-4(x + 4)² + 9(y + 2)² = 36 Factor trinomials

Divide by 36
Simplify
D. 6x + 34 > 82 is the answer
Answer: 686 N
Step-by-step explanation:
Hi!
Second Newton's law is: F=m*a, where F is force, m is mass, and a acceleration
On the Earth's surface, weight is the gravity force W=m*g, where g=9.8 m/s² is the acceleretion of gravity on Earth. So the weight of someone with mass m=70 kg is W=70*9.8 kg*m/s² = 686 N.
The unit N (Newton) is defined as 1 N = 1 kg*m/s²
