If the resultant line is a straight line,it represents a direct variation.
Answer:
y = mx + b
slope(m) = -2/3
(2,-5)...x = 2 and y = -5
now we sub, we r looking for b, the y int
-5 = -2/3(2) + b
-5 = - 4/3 + b
-5 + 4/3 = b
- 15/3 + 4/3 = b
- 11/3 = b
equation is : y = -2/3x - 11/3...but we need it in standard form
Ax + By = C
y = -2/3x - 11/3
2/3x + y = - 11/3....multiply by 3
2x + 3y = -11 <== standard form
Since the carts stick together and come to rest after the collision, the initial speed of the 3.0-kg cart is 12 m/s.
Given the following data:
To find the initial speed of the 3.0-kg cart, we would apply the law of conservation of momentum:
For a perfectly inelastic collision:
When the carts stick together and come to rest after the collision, the final velocity is zero (0).
Substituting the given parameters into the formula, we have;
Initial speed = 12 m/s

Answer:
m∠A = 60°
Step-by-step explanation:
Complementary Angles add up to 90°
Step 1: Set up equation
8x + 20 + 7x - 5 = 90
Step 2: Solve for x
15x + 15 = 90
15x = 75
x = 5
Step 3: Find m∠A
m∠A = 8x + 20
m∠A = 8(5) + 20
m∠A = 40 + 20
m∠A = 60°
3x − 5y + 3z = 9
