Answer:
B -3.
Step-by-step explanation:
The slope = (y2-y1)/(x2-x1)
= (-2-4)/(8-6)
= -6/2
= -3.
Answer:
x = -2, 1/2
Step-by-step explanation:
Step 1: Isolate everything to 1 side
2x² + 3x - 2 = 0
Step 2: Factor
(2x - 1)(x + 2) = 0
Step 3: Find roots
2x - 1 = 0
2x = 1
x = 1/2
x + 2 = 0
x = -2
So,
If this was mental math, I would round 1.87 to the nearest pound and 2.46 to the nearest half pound, making the following addition problem:
2 + 2.5 = 4.5
Because 1.87 is closer to 2 than to 1.5 or 1, and 2.46 is sooo close to 2.5.
So I would say about 4.5 pounds of meat.
But if you're rounding to the nearest pound for both, then you have this equation:
2 + 2 = 4
Because in 1.87, 8 is greater than or equal to 5, and in 2.46, 4 is less than or equal to 5.
So in that case, it would be about 4 pounds of meat.
