Answer:
-12/5 = -1 2/5 = -1.4 and 6 1/2 = 13/2 = 6.5
Step-by-step explanation:
<span>y=1/5x+5 with the point (-6, 0)
The line perpendicular to this line will have a slope that's the negative reciprocal of this one. So if the slope here is 1/5 (based on y=mx+b, where m is the slope), then the perpendicular slope would be -5/1.
So now that you have the point and the slope, use the point-slope formula.
y - y</span>₁ = m(x - x₁)
m = -5
(x₁, y₁) = (-6, 0)
y - 0 = -5(x + 6)
y = -5x - 30
y = -5x - 30 is the line perpendicular to y=1/5x+5.
The correct answer is 0.56. Hope this helps.
Answer:
2/5
Step-by-step explanation:
Average is the ratio of the sum of the data to the sample size
Sum of data = 2/5-4/5+9/5/+1/5
Sum of data = (2-4+9+1)/5
Sum of data = 8/5
Sample size = 4
Average = 8/5÷4
Average = 8/5× 1/4
Average = 2/5
Hence the average monthly change in water level is 2/5
Circle: When x and y are both squared and the coefficients on them are the same — including the sign.
For example, take a look at 3x2 – 12x + 3y2 = 2. Notice that the x2 and y2 have the same coefficient (positive 3). That info is all you need to recognize that you’re working with a circle.
Parabola: When either x or y is squared — not both.
