Answer:
2.0833
Step-by-step explanation:
2 3/4 + 3 1/2 =6.25
6.25(1/3)=2.0833
We factor the denominators
Factor x^2 - 16
x^2 - 4^2
We use a^2 - b^2 = (a+b)(a-b)
so x^2 - 4^2 = (x+4)(x-4)
Replace it in the given equation
Excluded values are the values that makes the denominator 0
we have (x-4) and (x+4) in the denominator
We set the denominator =0 and solve for x
x-4 =0
Add 4 on both sides
x= 4
x+4=0
subtract 4 onboth side
so x= -4
Excluded values are x=-4 and x=4
Answer:
C
Step-by-step explanation:
It costs 12 dollars per person so that will be the "slope" of the equation. The base is 100 dollars so that will be the y-intercept. Together it is 12x+100
Answer:
Step-by-step explanation:
Equation of a line which passes through two points (x1,y1) and (x2,y2) is given by:
(x1,y1) = (4,-2)
(x2,y2) = (-4,-4)
Substituting the values in the equation:
