Um try c but i’m just guessing sorry
4y = -23 + 39
4y = 16
y = 4
Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9
x = -9
y = 4
Answer:
He should have used the median and IQR because of the outlier.
Step-by-step explanation:
The better statistical measures to employ when a data set contains outliers are the median and IQR.
From the question, it is possible to draw an inference that the home prices for Cinnamon Court are higher than those of Pepper Hill Road by employing the median.
Also, it is possible to draw an inference that home prices on Cinnamon Court are less variable than on Pepper Hill by using the IQR.
To factor this notable trinomial, you have to find two numbers that summes give -5 and multiplied give 6*(-25) = -150
Then let's call n1 and n2 the two numbers and a the number before x^2 (6)
ax^2+sx+fn = (ax + n1)(x + n2/a)
Numbers are -15 and +10
-15+10 = -5
-15*10 = -150
So
(6x-15)(x + 10/6)
Or write it as a sum
6x^2 + 10x - 15x - 25
And factor
6x^2 + 10x = 2x(3x+5)
-15x-25 = -5(3x+5)
(2x-5)(3x+5)
