The equation of a line in slope intercept form is y=mx+b, which when you plug in the numbers becomes y=2x-1.
The variable a cannot be zero because that would make -9a = zero and 8 divided by zero is indeterminate.
X^2+4x-12
x^2+6x-2x-12
x(x+6)-2(x+6)
(x-2)(x+6)
So, B is the answer
Answer:
That probability is 0.1838 or 18.4% or enter 18.4
Step-by-step explanation:
mean 35 sd 5
20 is 3 sd s to the left of the mean
30 is 1 sd to the left.
The empirical rule has 68% within 1 sd or 34% on one side
It has 95% within 2 sd or 47.5% on one side
It has 99.7% within 3 sd or 49.85% on one side
Therefore between 3 sd and 1 sd on one side is 49.85-34=15.85% or enter 15.9
mean of 48 sd 7
between 48 and 55 is between -1 and 0 sd or 34% enter 34. The last one doesn't seem to post easily:z=(x-mean)/sd or z< (1217-1481)/293 or z <-264/293 or -0.901,
That probability is 0.1838 or 18.4% or enter 18.4
Answer:
The slope would be -2 with a y-intercept of (0, -3).
I hope this helped to answer your question.
