X + 4y = 9 Convert to slope / intercept form:-
y = (-1/4)x + 9/4
so the line perpendicular to this will have a slope -1 /(-1/4) = 4
so our equation will be y - y1 = 4(x - x1) where x1y1 is a point on the line.
x1 = 8 and y1 = -3:-
y - -3 = 4(x - 8)
y = 4x - 35
-4x + y = -35 is the answer
<span>Which of the following inequalities is correct?
-9 ≥ -7 is wrong as 9>7 but -9 < -7
-10 > |-10| is wrong as </span>|-10|= 10<span>
6 ≤ |-6| is right cause </span>|-6| =6 and we have 6=6 or <span>6 ≤ |-6| is also right</span><span>
0 < -13 is totally wrong

Answer:
Is the power produced directly proportional to the wind speed.
No.
A proportional function can be described as y = a * x
So (0, 0) is on the graph, not (3, 0).
0 / 3 = 0
3800/6 = 633.33
7600/9 = 844.44
13600/12 = 1133.33
The quotient y/x should be always the same.
Answer:
Ecological correlation
Step-by-step explanation:
According to a different source, the options that come with this question are:
- Ecological correlation
- Extrapolation
- Lurking variable
- Influential observation
Sarah should be careful about the use of an ecological correlation. An ecological correlation describes two variables that are group means, as opposed to a correlation between two variables that describe individuals. In this case, Sarah did pick 75 random students in each state. However, she then obtained the height and weight means for each state, and proceeded to compare these. Therefore, Sarah is not comparing individual values, but means. It is important to notice this, because correlations at a group level can be much higher than those at the individual level.
Answer:
see below
Step-by-step explanation:
First, she should subtract 6 from both sides of the inequality. This makes it so that the x terms are on one side and the non-x terms are on the other side so she can then solve for x by multiplying the entire inequality by 2.
