Answer:
B and D
Step-by-step explanation:
A can't be correct because the length of a segment is always positive. B is correct because we have to take the absolute value of the distance between endpoints to find the length of the segment. C is not correct because AC is obviously longer than BC so how would AB + AC = BC? D is correct because it models the Parts Whole Postulate.

Juan owes his cousin, Benito, $10.00. Benito is tired of waiting for Juan to pay him back. To try and get Juan to pay up more quickly, Benito has decided to add $1.00 per day to the amount Juan owes him. Juan also owes his brother, Tavon, $15.00. Tavon liked Benito's idea of charging additional money, but because he is Juan's brother, decided he would only charge $.50 per day. Write and solve an equation that shows the number of days it will take for Juan to owe Benito and Tavon the same amount of money

Answer:
Equation: 10+x= 15 +0.5x
Time: 10 days
Amount: 20$
Step-by-step explanation:
Equation for Benito:
10 + x*1Equation for Tavon:
15 + x*0.5Since the sums equalize at some time, we get:
10+x= 15 +0.5xx - 05x = 15- 100.5x = 5x= 5/0.5x= 10 daysAfter 10 days, Juan will owe both Benito and Tavon $20

Consider the table for the exponential function, LaTeX: p\left(x\right)=2^xp ( x ) = 2 x, shown below. Calculate the Average Rate of Change between the interval [2, 6].
Answers
Answer:
15
Step-by-step explanation:
To find the average rate if change of the exponential function between the interval [2, 6], use the formula, [tex] m = \frac{p(b) - p(a)}{b - a} [/tex]
Where,
[tex] a = 2, p(2) = 4 [/tex]

find the equation of the line passing through the point (-4,1) and the perpendicular to the line y=1/3x+4
Answers
Answer:
The answer is
[tex]y = - 3x - 11[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question
[tex]y = \frac{1}{3} x + 4[/tex]Comparing it with the general equation above
Slope / m = 1/3
Since the lines are perpendicular to each other the slope of the other line is the negative inverse of the original line
That's
Slope of perpendicular line = - 3
Equation of the line using point (-4 , 1) and slope - 3 is
[tex]y - 1 = - 3(x + 4) \\ y - 1 = - 3x - 12 \\ y = - 3x - 12 + 1[/tex]We have the final answer as
y = - 3x - 11Hope this helps you

(See explanation below for further details)
Step-by-step explanation:
A second order polynomial (quadratic function) can be well represented with at least three distinct points. Let is take five equidistant different points:
x = 0
[tex]f(0) = 3\cdot (0)^{2}-8\cdot (0) +2[/tex]
[tex]f(0) = 2[/tex]
x = 1
[tex]f(1) = 3\cdot (1)^{2}-8\cdot (1)+2[/tex]
[tex]f(1) = -3[/tex]
x = 2
[tex]f(2) = 3\cdot (2)^{2}-8\cdot (2)+2[/tex]
[tex]f(2) = -2[/tex]
x = 3
[tex]f(3) = 3\cdot (3)^{2}-8\cdot (3)+2[/tex]

The expression 98 divided by 3 to a mixed number is 32 2/3
How to change the quotient 98 divided by 3 to a mixed numberFrom the question, we have the following parameters that can be used in our computation:
Number = 98 divided by 3
Divide 98 by 3
so, we have the following representation
Quotient = 32
Next, we have
Remainder = 98 - 32 * 3
Evaluate the products
Remainder = 2
Hence, the fraction to a mixed number is 32 2/3
