Answer: Since the y intercept is (0, 4), b = 4 and the slope, m, is given as 2/3.
Step-by-step explanation:
Let the weight of triangle be x units. You are given that the weight of square is 1 unit.
1) On the left side of the balanced beam you can see 3 triangles and 5 squares. The weight on left side is 3·x+5·1=3x+5 units.
2) On the right side of the balanced beam you can see 2 triangles and 7 squares. The weight on right side is 2·x+7·1=2x+7 units.
3) If the whole system is balanced, then the weights on left and right sides are equal:
3x+5=2x+7.
Solve this equation:
3x-2x=7-5,
x=2 units.
Answer: option A
Answer:
y=-2x-4
Step-by-step explanation:
The slope has a Y-intercept at the -4, which narrows the choices down to 2. Since the slope is leaning left, it's a negative, which will make the answer to this y=-2x-4
