Answer:
y = -4x + 7
Step-by-step explanation:
As we can see, we want to write the equation of the line
we have this as;
y = -4x + b
To get the y-intercept, we use the values in the point given
we substitute x = 9 and y = -29
So we have;
-29 = -4(9) + b
-29 = -36 + b
b = 36-29
b = 7
So the equation is;
y = -4x + 7
The answer is (x+5)(x-8)

<span>P(9,12): For all intents and purposes, the hypotenuse is "r", the opposite side is "y", and the adjacent side is "x".
x = 9 (from the P(9,12))
y = 12 (also from the point)
Using the Pythagorean Theorem, you find out that r = 15.
Therefore, since cos θ = x/r
cos θ = 9/15 or 3/5
Answer: 3/5</span>
Answer:
x = 3; y = -6
Step-by-step explanation:
x - 2y = 15
2x + 4y = -18
Multiply both sides of the first equation by 2. Write the second equation below it, and add the two equations.
2x - 4y = 30
(+) 2x + 4y = -18
---------------------------
4x = 12
4x/4 = 12/4
x = 3
Now we substitute 3 for x in the first equation and solve for y.
x - 2y = 15
3 - 2y = 15
-2y = 12
y = -6
Answer: x = 3; y = -6
3. Greater than
Median is the middle number of the data set. But in this senario, there are 2 numbers in the middle. So you can take 4+5/2=4.5
To find Mean, you can must take all the numbers in the data set divided by the number of data collected.
In this case, (3+3+4+5+5+9)÷6
You will find that the mean is greater than the median.
