Answer:
The answer to your question is 1
Step-by-step explanation:
Data
slope = m = -3
y-intercept = 3
Process
1.- Find the equation of the line in the slope-y-intercept form
y = mx + b
-Substitution
y = -3x + 3
2.- Find the x intercept
-If y = 0
0 = -3x + 3
-3 = -3x
-3/-3 = x
x = 1
-The x-intercept is 1
Answer:
x= 14, –12
Step-by-step explanation:
The given question might make you believe that it's difficult due to it's frightening digit (168) but in fact in you use the following methods, it's going to be a pieces of cake.
the delta formula:
Δ=b²–4ac===> (–2)²–4(1)(–168)=676
well this can be on of the methods and the other one is
The full square formula:
[/tex]
now what you need to do is to put this on both side of the equation (½b)²=1
Its either D or A go with ur gut I think u got it right :)

A standard deviation of 24 means that the actual scores of students range from 24 less than to 24 greater than the mean (average) score of 120. So to find the score that is half a deviation less than the mean score, you would divide 24 by 2 (to get half the mean) and then subtract that number from 120 (the average score).
