Find the GCF (Greatest Common Factor)
GCF = 3
Factor out the GCF ( Write the GCF first. Then, in parentheses, divide each term by the GCF)
3(3x^2/3 + -12x/3 - 15/3)
Simplify each term in parentheses
3(x^2 - 4x - 5)
Factor x^2 - 4x - 5
<u>3(x - 5)(x + 1)</u>
Answer:
A) y = 0.76x + 3.72
Step-by-step explanation:
Data points: (2, 5) and (11,12)
Slope:
m=(y2-y1)/(x2-x1)
m=(12-5)/(11-2)
m=(7)/9
m= 0.78
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = 0.78(x - 2)
y - 5 = 0.78x - 1.56
y = 0.78x + 3.44
Choice A is the closest to this solution

Answer:
x = 6
Step-by-step explanation:
The sum of segments is used:
EF +FG = EG
3x +(5x +16) = 11x -2 . . . . substitute given expressions
8x +18 = 11x . . . . . . . . add 2
18 = 3x . . . . . . . . subtract 8x
6 = x . . . . . . divide by 3
The value of the variable is 6.
__
<em>Check</em>
The segment lengths are ...
EF = 3x = 3·6 = 18
FG = 5x+16 = 5·6 +16 = 46
EG = 11x -2 = 11·6 -2 = 64 = 18+46 . . . answer is correct
