Answer:
y = 3x + 2
y = 6x – 3
y = 2/3x + 6
y = –1/3x – 4
y = 2x + 1
Correct answer:
y = 3x + 2
Explanation:
Convert the equation to slope intercept form to get y = –1/3x + 2. The old slope is –1/3 and the new slope is 3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2
So y = 3x + 2
The answer is the first choice.
P(both even) = (4P1)(3P1) / 9P2
$819.73/$1192.64 × 100% ≈ 68.73%
So change from 50 to 35
first find change
50-35=15
50=100%
15=x%
percent means parts out of 100
15 out of 50=x/100
15/50=x/100
30/100=x/100
30=x
the answer is 30% change
