Answer:
3 (m^2 - 16)
Step-by-step explanation:
factoring means taking out a common multiple of all the terms in the expression
in this case, if you multiply 3 and m^2, 3 and -16, you would get 3m^2-48
so you take the three and put it outside of the parenthesis that contains the factored terms
this leaves you with 3 (m^2 - 16)
Answer:
Step-by-step explanation:
A coefficent is the number in front of the letter and a constant is just a number
Answer:
1) after 4 weeks, Lin has more with $65
2) after 3 weeks they both have same amount
Step-by-step explanation:
let 'w' = number of weeks
1) <u>equation for Han</u>: y = 100 - 15w
y = 100 - 15(4)
y = 100 - 60
y = $40 after 4 weeks
<u>equation for Linn</u>: y = 25 + 10w
y = 25 + 10(4)
y = 25 + 40
y = $65 after 4 weeks
2) 100 - 15w = 25 + 10w
75 - 15w = 10w
75 = 25w
w = 3 weeks
Answer:
y=1/3x -4
Step-by-step explanation:
3y-x=-12
y= 1/3x-4
m=1/3
(gradient is the same since its parallel)
y=mX+c
(2) = 1/3(18) + c
2 = 6 + c
2 - 6 = c
c= -4
(y-intercept)
Therefore: y=1/3x-4
