Answer:
b = 
Step-by-step explanation:
b +
= 1
← change to an improper fraction
b +
= 
Multiply through by 12 ( the LCM of 3 and 4 ) to clear the fractions
12b + 8 = 15 ( subtract 8 from both sides )
12b = 7 ( divide both sides by 12 )
b = 
Answer:
W=A/L
Step-by-step explanation:
If the area of the rectangle is L*W, you can just rearrange the equation A=L*W to get W=A/L, an equivalent equation.
Answer:
(3,1.5)
Step-by-step explanation:
first write the formula of finding the midpoint
step 1: M=(x1+x2÷2,y1+y2÷2)
step 2: substitute for coordinates x1,x2,y1 and y2
step 3:(-8+2÷2,5+-2÷2)
step 4: (-6÷2,3÷2)
step 5: (-3,1.5)
im done
The slope of this trend line is m = (0-28) / (14-0) = -2. The y-intercept can be read directly from the graph: It is 28. Thus, the equation of this trend line is k = -2J + 28.
