Answer:
51 ft
Step-by-step explanation:
y-12 = -1/4 (x-3) = 51 ft
Answer:
y=-3/2x+13
Step-by-step explanation:
Convert to slope-intercept form (y=mx+b):
-3x+2y=10
-3x-10+2y=0
-3x-10=-2y
-3/2x-5=y
y=-3/2x-5
Parallel lines have the same slope, so the slope of the equation will be m₁=m₂ where -3/2=-3/2
Solving for b, the y-intercept, we get:
y=-3/2x+b (Equation so far)
7=-3/2(4)+b [Plugging in (4,7)]
7=-12/2+b
7=-6+b
13=b
Therefore, the equation of the line that is parallel to the line -3x+2y=10 and goes through the point (4,7) is y=-3/2x+13
Answer:
Step-by-step explanation:
The closer the r value is to 1, the stronger the correlation between the numbers. If r is positive, then the slope of the data points tend towards a positive, while if r is negative, then the slope of the data points tend towards a negative. If r = .96, the value is close to 1 and is positive, so it has a strong positive correlation. If r = -.06, the value is far from 1 and is positive, so it has a weak positive correlation. This means that the x and y values for the data do not make sense together. For example, if x was the temperature outside and y was the number of people wearing coats and you observed 20 people outside, a strong correlation coordinate might be (-15, 19). This means that when the temp was -15, 19 people out of 20 will be wearing a coat, which makes sense. If you had that only 2 people wore coats, the data together doesn't make any sense.
