Answer:
GCF(15a; 28b²) = 1
Point-slope form is y1 - y2 = m(x1 - x2). We know that the slope is 2, and we have a point of (1, -1). If we plug in our numbers, we will get y -(-1) = 2(x - 1). This gives us y + 1 = 2(x - 1). Therefore, the answer is B.
The slope will be the same, so we know the equation will be y=-2x+b. But there is a different b.
For x=4, y will be 1 because the point (4,1) is given.
So 1=-2*4 + b => b = 9
So the equation of our parallel line is y=-2x+9
If we subtract 1 from both sides, we get y-1 = -2x + 8
Then factor out -2 on the right hand side: y-1 = -2(x - 4)
That's answer A!
Answer:
2
Step-by-step explanation:
Factors for 50: 1, 2, 5, 10, 25, 50
Factors for 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Both share factors 1 and 2, therefore your final answer is 2 since it's the greatest digit in this case.
