Yes, they can have both positive and negative oxidation numbers.
Answer:
5y = -2x + 31
Step-by-step explanation:
Given equation:
y = 
Coordinate = (-7,9)
Unknown:
Equation of the line perpendicular = ?
Solution:
The slope - intercept format of a line is given as;
y = mx + c
where y and x are the coordinates
m is the slope
c is the y-intercept
y = 
From the given equation; slope is 
A line perpendicular will have a slope that is negative and the inverse of this;
slope of perpendicular line = 
Since y= 9 and x = -7;
So;
9 =
+ C
9 =
+ C
C = 9 -
= 
Now,
y =
x + 
mulitply through by 5;
5y = -2x + 31
Answer:
Step-by-step explanation:
3x-6y=48
Turn the equation into slope intercept form (y=mx+b)
x-2y=16 (Subtract x)
-2y=16-x (Divide by -1/2)
y=1/2x-8
The y-intercept is b, so -8 is the y-intercept.
The slope is m, so the slope is 1/2.
The probability that the cat lands on its feet both times it falls out of a tree is 0.85
<h3>How to determine the probability?</h3>
The probability that the cat lands on its feet is given as:
P(Feet) = 0.92
The probability that it lands on its feet twice is calculated using:
P = P(Feet) * P(Feet)
So, we have:
P = 0.92 * 0.92
Evaluate
P = 0.85
Hence, the probability is 0.85
